BACKGROUND OF THE INVENTION

The inventions and embodiments thereof of this subject patent application may pertain to devices, systems, and/or methods of thermal therapies and/or hydrotherapies to the whole human body or portion(s) thereof, such as, but not limited to, the face and/or the head. The human face in particular has some unique anatomical features (e.g., unique neuroanatomical circuitry and vasculature features) that makes thermal therapies and/or hydrotherapies applied to the face more desirable than targeting many other portions of the human body.

I. Brief History of Hydrotherapy

The history of hydrotherapy dates back thousands of years. Hydrotherapy, used since the time of the ancient Egyptians to promote healing, has the potential to boost mental, physical, and emotional health and may benefit those with specific medical conditions. Immersion in cold or hot water was used for health and wellness purposes in ancient Egyptian, Greek, Roman, Celtic, Indian, and Hebrew societies. Therapeutic practices utilizing hydrotherapy have been documented in ancient Chinese society, where cold water with tea extracts was used specifically to relieve pain and treat burns since 1550 BC. In ancient Greece, warm water baths were enhanced with minerals in order to treat various illnesses.

The father of “modem” hydrotherapy is thought by many to be Vincent Priessnitz, an Austrian farmer bom in the 1700’s who prescribed combinations of “water, food & air” in place of traditional medicine as cures for common ailments. Subsequently, a Bavarian priest by the name of Sebastian Kniepp advocated for Priessnitz’s work with hydrotherapy, which lead to formal administration of the technique by health professionals in Europe.

Hydrotherapy may have introduced to the United States (U.S.) in 1844 at a clinic in New York City. Hydrotherapy spas sprung up in various U.S. cities; a tourism industry became established focused around these spas, particularly among the wealthy elite. Due to the rise and eventual dominance of allopathic medicine in the twentieth century, the popularity of hydrotherapy waned as it was relegated to a position of “alternative” medical therapy. However, the therapeutic benefits of hydrotherapy are profound and are beginning to be rediscovered in recent years and appreciated once again. Hydrotherapy has the added benefit of being relatively low cost and relatively accessible to the general population, as compared to other treatment modalities.

II. Hydrotherapy: Mechanisms of Action

Hydrotherapy may utilize one to three mechanisms of action, namely, thermal, mechanical, and/or chemical.

A. Thermal

Water is four (4) times more efficient at heat transfer than ambient air. Thermal delivery devices, systems, and/or methods of use may leverage this heat transfer property of water (or other liquids) along with the anatomical fact of the trigeminal nerve, and/or that the upper half of the (human) face contains glabrous skin. Recall, together with the palms/soles, the (upper) face is the most efficient region of human body for heat transfer (because of arteriovenous anastomoses [AVAs]). Facial sensitivity to temperature most likely enhances the thermal therapeutic effect of hydrotherapy.

Cold water induces peripheral vasoconstrictive effects in addition to decreased nerve cell conductivity. These responses could potentially be utilized to interrupt pain signaling pathways. Warm water, on the other hand, prompts vasodilation in the vasculature which can subsequently improve blood flow and tissue perfusion/ oxygenation.

B. Mechanical

Three mechanical properties contribute to the efficacy of traditional hydrotherapy: buoyancy, hydrostatic pressure, and density. Such mechanical properties may offset gravity, serves as a form of resistance and compression, and acts as a thermal conductor.

C. Chemical

The chemical properties of water to dissolve waste solutes for excretion and create free ions when combined with minerals, are thought to provide further therapeutic benefit. Exogenous drugs can be added to a water bath to facilitate transdermal administration of therapeutics. Transdermal drug application can also take advantage of the vasodilation associated with warm water immersion. Oxygen nanobubbles in water can also have additional beneficial effects. One study demonstrated that oxygen-nanobubble water enhanced growth of both plants and animals (trout and mice).

III. Skin

Skin (cutaneous) sensory nerve endings in the skin may elicit sensations of: touch, itch, warmth, cold, and pain. Nerve branches may enter the skin (dermis) from the subcutaneous fat and form superficial and/or deep nerve plexuses. Unmyelinated nerve branches from either plexus may terminate in nerve endings that may be simple or specialized. Terminals from a single axon may serve an area as broad as one (1) square centimeter and may overlap with nerve endings from other axons. Note, all (to a majority of) axons that end in the epidermis are nociceptors; i.e., neurons that transmit pain messages. Nerve densities of range between 2 and 3,976 neurites per square millimeter of skin surface, depending upon the skin location and the individual. However, the hands and the face are the most densely innervated regions with respect to skin nerves. Inflow of cutaneous sensory information from skin (cutaneous) sensory nerve endings is strongly controlled and modulated by the cerebral cortex of the brain. The skin has a high sensitivity to rapid mechanical stimulation, with positional movements of less than 1 micrometer (pm) detectable.

Sensations of cold persist continuously when skin temperature is below eighty-six (86) degrees Fahrenheit (°F) (or thirty [30] degrees Celsius [30 °C]), and sensations of warmth persist continuously when skin temperature is above 98.6 °F (37 °C). Changes in temperature of 0.054 °F (0.03 °C) may be detected, especially if the skin temperature changes faster than 0.126 °F per second (sec) (0.007 °C/sec). Important to at least some embodiments described herein is that thermal sensitivity is highest on the face. At skin temperatures below 64.4 °F (18 °C) or above 113 °F (45 °C), pain (e.g., as a burning sensation) is produced. Pain may also be induced by pressure greater than fifty (50) grams per square millimeter and/or by disruption of the skin. See e.g., William L. Weston, MD, et al., Chapter 1, Color Textbook of Pediatric Dermatology (Fourth Edition), 2007.

Thus, thermal stimulation of skin (cutaneous) sensory nerve endings may produce sensations of pain (cold and/or heat), at skin temperatures below 64.4 °F (18 °C) or above 113 °F (45 °C), which may be a cornerstone for at least some embodiments described herein. Studies also show that pain is at least associated with higher activity in the brain’s parabrachial nucleus (PBN); and that facial pain is associated with higher activity in the PBN as compared to body pain. Facial skin is more sensitive to pain than body skin. This is likely due to the face being a densely innervated region; that at least a majority of facial (and/or cranial) nerves being directly wired (connected) to the brain versus body (spinal) nerves that are indirectly wired (connected) to the brain via the spinal cord; and because the distance a nerve signal must travel from cutaneous nerve endings to the brain (for signal interpretation) is generally (mostly) shorter for facial (and/or cranial) nerves than body nerves connected to the spinal cord. Sensory neurons from the head and face are wired directly into one of the brain's principal emotional signaling hubs, while sensory neurons from the body are connected only indirectly (e.g., via the intermediary of the spinal cord). See e.g., Erica Rodriguez, et al., A craniofacial- specific monosynaptic circuit enables heightened affective pain, Nature Neuroscience, 2017.

IV. Cranial Nerves

Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), in contrast to spinal nerves (which emerge from segments of the spinal cord). Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head, including the face, and the neck. The cranial nerves are usually/often considered components of the peripheral nervous system (PNS), although on a structural level the olfactory, optic and terminal nerves are more accurately considered part of the central nervous system (CNS). In humans there are typically twelve (12) pairs of cranial nerves: (I) olfactory nerve (mostly afferent); (II) optic nerve (mostly afferent); (III) oculomotor nerve (mostly efferent); (IV) trochlear nerve (mostly efferent); (V) trigeminal nerve (afferent and efferent) (see FIG. 38); (VI) abducent nerve (mostly efferent); (VII) facial (intermediate) nerve (afferent and efferent; (VIII) vestibulocochlear nerve (mostly afferent); (IX) glossopharyngeal nerve (afferent and efferent); (X) vagus nerve (afferent and efferent); (XI) accessory nerve (mostly efferent); and (XII) hypoglossal nerve (mostly efferent). The (V) trigeminal nerve is often broken down in three subnerves, the ophthalmic nerve, the maxillary never, and the mandibular nerve. The twelve (12) pairs of cranial nerves are nerves associated with the brain. The fibers in cranial nerves are of diverse functional types. Some cranial nerves are composed of only one type, others of several. In cranial nerve attachment to the brain, the first two cranial nerves (I) and (II) are associated with the forebrain, nerves (III) and (IV) with the midbrain, and nerves (V) to (XII) with the hindbrain. Cranial nerves generally permit one-way communication or two-way communication, meaning that some cranial nerves transmit information at least mostly to the brain (afferent), others at least mostly only transmit instructions out (efferent) from the brain, and the remainder are structured to receive and transmit information. Cranial nerves that are exclusively or mostly afferent are (I), (II), and (VIII); the mostly efferent cranial nerves are (III), (IV), (VI), (XI), and (XII); and the cranial nerves that contain both afferent and efferent fibers are (V), (VII), (IX), and (X). At least some embodiments of the present invention may benefit more from thermally stimulating afferent cranial nerves.

V. Neurotransmitters

Additionally, studies show that PBN stimulation/activation is associated with neurotransmitter production, such as, but not limited to, dopamine. Similarly, pain is associated with neurotransmitter (such as, but not limited to, dopamine and noradrenaline [norepinephrine]) re- lease/production.

For example, plasma noradrenaline (norepinephrine) and dopamine concentrations were increased by 530% and by 250% respectively from a body (not face) cold water immersion at 57.2 °F (14 °C) that generated skin pain at this cold temperature. See e.g., Sramek P, el al., Human physiological responses to immersion into water of different temperatures, Eur. J. Appl. Physiol., 2000.

Note, production and/or release of dopamine from thermal (cold and/or hot) therapy may be superior to dopamine release from exercise, as dopamine from exercise tends to be rapidly metabolized solely for energy thus limiting dopamine’ s role as a neurotransmitter and/or hormone.

In the brain, serotonin modulates mood, anxiety, appetite, and potentially cognitive performance. Serotonin regulates thermogenesis in brown adipose tissue (BAT) with effects on energy balance, obesity, and related metabolic conditions. Thermogenesis in BAT may be activated by cold exposure or by activating the sympathetic nervous system, resulting in conversion of energy resources into heat, instead of activating ATP (adenosine triphosphate) synthase to produce ATP for regular cellular metabolism. The sympathetic nervous system itself may be activated by cold exposure. Serotonin may be produced and/or released as a result of cold exposure.

Exposure to cold is known to activate the sympathetic nervous system and increase the blood level of beta-endorphin and noradrenaline and to increase synaptic release of noradrenaline in the brain as well. Additionally, due to the high density of cold receptors in the skin, cold therapy may result in sending sufficient electrical impulses from skin nerve endings to the brain, which may result in an anti-depressive effect. While dopamine, noradrenaline, and/or serotonin may boost mood, among other effects, oxytocin may play important roles in feelings of love/bonding, psychiatric, metabolic, blood sugar, and/or immune system pathways. Oxytocin may also play important roles with maintaining bone density and a youthful body composition. Further, oxytocin deficiency is associated with low mood. Ensuring adequate oxytocin levels may be important to maintenance of good physiological and psychological health. Release of oxytocin may promote thermogenesis, brown fat cell production, and/or burning of fat for warmth. Cold exposure may upregulate produc- tion/release of oxytocin in the hypothalamus in the brain. Like dopamine, noradrenaline, serotonin, and endorphins, oxytocin may also be released and/or modulated via cold exposure.

Thus, thermal stimulation of skin (cutaneous) sensory nerve endings may produce sensations of cold, warmth, and/or pain, at skin temperatures below 64.4 °F (18 °C) or above 113 °F (45 °C); and this thermal stimulation may thus in turn cause release of neurotransmitters (such as, but not limited to, dopamine, noradrenaline [norepinephrine], endorphins [e.g., beta-endorphin], serotonin, oxytocin, the four happy hormones, and/or the like).

Also note, that thermal stimulation of skin (cutaneous) sensory nerve endings is not just limited to producing sensations of cold, warmth, pain, and/or neurotransmitter release. Thermal (cooling and/or heating) stimulation of skin (cutaneous) sensory nerve endings may produce other and/or additional results, such as but not limited to, vasodilation; vasoconstriction; changes in plasma renin activity; changes in plasma cortisol; changes in blood aldosterone; diuresis; changes in rectal temperature; changes in peripheral catecholamine concentration; changes in cerebral blood flow; respiratory system changes; nervous system changes; changes in musculoskeletal system; changes in the gastrointestinal system; changes in reproduction systems; changes in urinary and/or renal system; changes in hematology; changes in immunology; hormonal changes; changes in the endocrine system; changes in the eyes; changes in the skin; changes in hair; and/or changes in temperature regulation. See e.g., Mooventhan, et al., “Scientific Evidence-Based Effects of Hydrotherapy on Various Systems of the Body,” North American Journal of Medical Science, Volume 6, Issue 5, May 2014, which lists many health and/or medical issues that are affected by, changed by, and/or improved by various thermal therapies; wherein the teachings of this reference are incorporated by reference as if fully set-forth herein.

Release, production, and/or control of neurotransmitters (such as, but not limited to, dopamine, noradrenaline [norepinephrine], endorphins [e.g., beta-endorphin], serotonin, oxytocin, the four happy hormones, and/or the like) and/or thermal therapy may be associated with a variety of health issues, medical conditions, and/or the like, such as, but not limited to: psychiatric conditions; depression; schizophrenia; bipolar, attention-deficit / hyperactivity disorder (ADHD); post-traumatic stress disorder (PTSD); multiple sclerosis (MS); tinnitus; mood swings, aggression, anxiety, panic attacks, dementia; Alzheimer's disease; Parkinson's disease; (tobacco and/or nicotine) smoking; (chemical) addiction; behavioral addiction; (chemical) dependence; behavioral dependence; obsessive-compulsive disorder (OCD); brain injury, headache; migraine; hangover; heart-rate; blood pressure; blood oxygenation; cardiovascular issues; blood glucose level; insulin level/sensitivity; sinus problems; eye problems; relieves pain and suffering particularly in rheumatism, fibromyalgia, and/or asthma; improves cardiac function and cardiac function in heart failure; improves peripheral blood flow in ischemic limbs; in myocardial infarction, thermal therapy increases eNOS vascular endothelial growth factor mRNA levels; provides a noninvasive therapy for myocardial infarction; improves exercise tolerance and endothelial function; improves peripheral circulation in cerebral palsy; reduces LDL cholesterol and increases HDL cholesterol; prevents (or prolongs onset) ischemic heart disease; reduces symptoms of ischemic heart disease; improves quality of life in patients with chronic obstructive pulmonary disease (COPD); improves bronchial patency; reduces frequency of infections; increases cutaneous blood flow; urine production; kidney health; cancer growth; sexual function (for men and women); metabolic rates; muscle growth; anti-aging; longevity increasing, slowing aging; reversing aging, portions thereof; combinations thereof; and/or the like.

For example, reduced norepinephrine and dopamine may be an important indicator for Alzheimer's disease; and non-reduced or higher norepinephrine and/or dopamine levels may be used to delay onset and/or treat Alzheimer's disease. For example, body (and not face) cold water (57.2 °F [14 °C]) immersion increased metabolic rate by 350 %. For example, increased dopamine levels have been shown to improve sexual function in men and in women. For example, dopamine makes the heart beat stronger and/or more forcefully, which in turn helps to circulate oxygen enriched blood more efficiently. For example, dopamine increases urine production, which helps the body rid itself of blood and/or tissue toxins. For example, in contrast to dopamine effects on differentiated cells, dopamine exerts an inhibitory effect on cancer growth (e.g., dopamine shown to slow brain cancer and breast cancer). For example, dopamine facilitates building muscle without working out/exercise.

For example, thermal therapy may reduce symptoms associated with chemical addictions and/or chemical dependencies, wherein such chemicals may include, but are not limited to: nicotine, alcohol, ethanol, caffeine, opioids, medications, over the counter medications, prescription medications, controlled substances, drugs, delta-9-tetrahydrocannabinol (THC), tobacco, mariju- ana, cocaine, benzodiazepines, glucose, sucrose, fructose, lactose, sugar, adrenalin, portions thereof, combinations thereof, and/or the like. Similarly, behavioral addictions and/or dependencies, such as, but not limited to, eating, food, sex, gambling, portions thereof, combinations thereof, and/or the like, may be improved by thermal therapies.

Thus, thermal stimulation of skin (cutaneous) sensory nerve endings, that produces neurotransmitters (such as, but not limited to, dopamine and noradrenaline [norepinephrine]) may be used to affect, change, treat, and/or reduce symptoms any of these medical conditions or the like. VI. The Trigeminal Access Point of the Human Face

A direct connection from facial sensory neurons to a nucleus in the brain, called the para- brachial nucleus, has been identified that delivers pain signals, and does not exist between sensory neurons in the body and the brain. Because of this, hydrotherapy and/or thermal therapy of the face may not only be more effective (than treating other portions of the human body) but also does so without the negatives of whole-body hydrotherapy, such as the difficulties in transporting and changing the temperature of large volumes of water, and the discomfort of exposing the entire body to cold water or hot water. Another key feature of the neuroanatomical circuitry of the face is its trigeminal nerve with its connections to the vagus nerve at the level of paratrigeminal nucleus in the brain and though its interactions with the baroreceptors in the neck, which promote parasympathetic outflow. Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein that target the face, may be used to stimulate vagus nerve activity in an easier, more efficient, safer, and less expensive way as compared to the vagus nerve stimulator.

Pain, light touch, pressure, vibration, temperature, and/or proprioception (spatial awareness) may be five forms of sensory information that are detected at or near the surface of the human face/head and relayed to the central nervous system by means of the trigeminal nerve - also known as the fifth cranial nerve (CN V). See e.g., FIG. 38 for a diagram of the trigeminal nerve (or see depictions of the trigeminal nerve in human anatomy books and/or videos). The trigeminal nerve is composed of three branches, the sensory ophthalmic nerve or VI (eye level), the sensory maxillary nerve or V2 (at the level of the cheek bone), and the mixed sensory and motor mandibular nerve or V3 (at the level of the jaw). The motor component of V3 controls the muscles of mastication (jaw muscles).

For the most part, sensory input from the human face navigates first to the trigeminal ganglion (TG) and then to centrally located trigeminal nuclei, while motor output flows in the opposite direction from the motor nucleus to the human face. The exception to this pathway is the route taken by proprioceptive afferents from muscle spindles in the muscles of mastication and other muscles of the head and neck. These proprioceptive fibers, which convey sensory information regarding jaw opposition and head position, travel to the mesencephalic nucleus, where their cell bodies reside. Superior to the TG, the mesencephalic nucleus is positioned in the caudal midbrain and rostral pons.

The TG resides just outside the human brainstem. There are two bilateral trigeminal ganglia, one on the right and left sides of the brainstem. The TG can be found residing within Meckel’s caves, existing immediately lateral to the superior pons. Within the TG lie the soma (aka cell bodies) of the pseudounipolar neurons that extend peripherally to innervate various structures of the face and the head (of a human).

After receiving sensory input from the human face, the first order sensory neurons within the TG then send out afferent projections that travel to the brainstem at the level of the mid-pons and either synapse there on the chief sensory nucleus (CSN) or continue downward along the spinal trigeminal tract (STT) and synapse in the spinal trigeminal nucleus (STN). Both the CSN and the STN contain second order neurons.

The STN is an elongated nucleus medial to the STT. Sensory afferents within the STT continue their descent until they reach their destination spot within the STN. The STN, which extends from the caudal pons into the upper cervical spinal cord, splits into three subnuclei, the pars oralis (most superior), pars interpolaris, and pars caudalis (most inferior). It is somatotopi- cally arranged, whereby sensory input from the lateral face lies more inferiorly while sensory input from medi l midline structures lie superiorly.

The pars caudalis extends from the inferior medulla to C2 or C3. The second order neurons in the CSN or STN then project fibers to third order neurons located in the thalamus, primarily the ventral posteromedial thalamic nucleus, via the trigeminothalamic tract. Third order neurons from the thalamus project to the postcentral gyrus of the primary sensory cortex. Animal studies using Evans blue indicate that the TG is not shielded by the blood brain barrier (BBB), which would make it accessible to drugs that are not CNS -penetrant. It has been suggested that the TG might be the anatomical target of certain anti-migraine drugs (e.g., monoclonal antibodies, gepants, and/or triptans). Transdermal therapies could also act directly on the TG without having to go through the BBB.

When viewed microscopically, different components of the TG have been identified. These include the neuron-glia unit (NGU), nerve bundles (consisting of grouping of individual nerve fibers), extracellular matrix with micro-vessels, and occasional mast cells and stromal cells. All the components are interdependent on one another. Within the NGU, there are three neurons covered by a divided layer of satellite glial cells. The lack of astrocytes might account for the absence of a true BBB.

The upper half of the human face is one of only three anatomical regions on the human body that contains “glabrous” hairless skin. Glabrous skin regions on the forehead, palms of the hands, and soles of the feet are capable of the most efficient heat transfer of any other location in the human body. This capacity for heat transfer is due to the distinct interface of the blood vessels directly beneath the skin. Everywhere else in the human body, blood usually flows from artery to capillary to vein. Glabrous skin regions contain unique vascular structures called arteriovenous anastomoses (also known as AVAs), where the blood flows directly from arteries straight into veins. Because there are no tiny capillaries to flow through, AVAs can absorb or give off significant amounts of heat (as compared to other regions of the human body without AVAs). IV. Neuroanatomy of the Trigeminal System & Related Structures

A. The Parabrachial Nucleus

Dopamine is an important chemical messenger, called a neurotransmitter, that is vital to establishing reward and motivation behavior (in humans). Numerous dopaminergic neurons (nerve cells) have been found to display a short-latency response to nociceptive (pain-related) sensory stimuli.

One study used multiple techniques to study the communication between the neurons in the parabrachial nucleus and dopaminergic neurons in the substantia nigra pars compacta (part of the basal ganglia important in orchestrating movement) and the ventral tegmental nucleus (a midbrain nucleus important in mediating reward, motivation, and repulsion), including tracer studies and concurrent extracellular recordings of neurons. The study authors found extensive interactions between parabrachial and dopaminergic neurons. They concluded that the parabrachial nucleus plays a key role in conveying short-latency nociceptive information to the dopaminergic neurons.

It is well-established that craniofacial pain is subjectively experienced more intensely than pain originating from other anatomical regions of the human body. This qualitative difference was observed in a study of human subjects which reported a subjective feeling of increased fear associated with facial pain in comparison to extremity pain, despite similar intensity ratings assigned to both stimuli.

Similarly, a human neuroimaging study revealed higher levels of amygdala activation on functional MRI (fMRI) when a noxious thermal stimulus was applied to the face, in comparison to when the same noxious stimulus was applied to the hand. Interestingly, repetitive application of noxious thermal stimuli to the extremities resulted in habituation (decreased perception of pain over time), whereas repetitive noxious stimulus to the face produced increased sensitivity to pain over time.

Greater facial sensitivity to pain was corroborated by an animal study on mice performed by researchers from Duke University Medical Center that observed heightened activation of the lateral parabrachial nucleus (a critical part of the affective pain circuit) involving greater numbers of neurons when noxious stimulus was applied to the face in comparison to the hindpaw. Through these experiments, the investigators identified a previously uncharacterized monosynaptic (involving one synapse, the tiny space between neurons across which chemical signals are sent) connection between craniofacial sensory neurons and neurons in the nociceptive lateral parabrachial nuclei. When this circuit was experimentally stimulated in mice, they responded by increasing avoidance behaviors and stress cries, while experimentally blocking the monosynaptic circuit decreased their facial pain sensitivity.

Thermal sensitivity on the (human) face is greater than anywhere else on the body. While this is clearly the case for noxious/painful/unpleasant stimuli, the same is likely to be true for more mild/ temperate thermal sensory input. Thermal delivery devices, systems, and/or methods as discussed herein may leverage this biological organization to maximize the benefits of hydrotherapy through its direct application to the (human) face.

B. Paratrigeminal nucleus

The paratrigeminal (PTG) nucleus consists of a mass of interstitial cells in the dorsal tip of the spinal trigeminal tract that collects sensory information from the vagus, trigeminal, spinal, and glossopharyngeal nerves and organizes this afferent neural input for nociceptive processing and mediating the baroreceptor reflex.

From its location rostral to the obex (the lowest point in the 4 ^th ventricle, or open space in the brain through which cerebrospinal fluid flows), the PTG nucleus serves an important role integrating visceral and somatosensory afferent information and likely modulates autonomic function through its projections to the dorsal vagal complex. The connections between PTG and the vagus are neurochemically unique, involving enkephalins (a naturally produced opiate) and nitric oxide, which dilates blood vessels amongst other functions.

C. Trigeminal-Baroreceptor reflex

Immersion of the (human) face in cold water slightly elevates blood pressure and induces baroreflex bradycardia (slowed heart rate). These results indicate that there is a coordinated in- teraction between trigeminal sensory information and carotid arterial baroreceptors that stimulates a vagal-mediated effect on cardiac activity. Some study authors suggest that trigeminal sensory afferent input to the central nervous system (from trigeminal cutaneous receptors) increases vagal cardiac outflow and then augments vagal responses to arterial baroreceptor input.

D. Trigeminal Nerve Control of Cerebral Blood Flow

Activation of the trigeminal nerve modulates cerebral blood vessels via three separate mechanisms, all of which improve cerebral blood flow (CBF). First of all, there is retrograde movement of the electrical discharge of the trigeminal nerve that triggers the expulsion of vasoactive peptides (protein signaling molecules that act on blood vessels) onto the cerebral vasculature leading to cerebrovasodilation. Secondly, sensory afferents of the trigeminal nerve are part of a parasympathetic reflex arc that enhances CBF through cerebrovasodilation. Thirdly, the trigeminal nerve directly communicates with the rostral ventrolateral medulla (RVLM), causing a pressor response (increasing systemic blood pressure). The RVLM, a vital medullary nucleus, helps to regulate systemic vasomotor changes.

Another access point for the trigeminal nerve’s influence on cerebral perfusion is through the sphenopalatine ganglion (SPG), an important supplier of parasympathetic innervation to the cerebrovasculature. The ability of SPG stimulation to vasodilate cerebral blood vessels, enhance ipsilateral CBF, and improve cortical perfusion was verified in preclinical studies. Research on rats and dogs suggests that it also enhances the permeability of the blood brain barrier (BBB). The SPG, which contains both autonomic and sensory nerves, has a close association with the trigeminal nerve. It may be the last synaptic connection in the trigeminal nerve impulse spread associated with the group of headaches known as the trigeminal autonomic cephalgias, which include cluster headaches. Furthermore, the SPG might play a key role in spreading the outflow of trigeminal electrical activity during migraine to the tissue layers lining the brain, called the meninges. The autonomic nerves of the SPG innervate the lacrimal glands and the nasal and sinus epithelia. It is located directly posterior to the bony structures of the nasal cavity within the pterygopalatine fossa of the skull.

The activity of the trigeminal nerve has a considerable influence on cerebral perfusion in both normal and disease states. The importance of cerebral perfusion to brain function and health cannot be overstated. Disease states that are overtly characterized by abnormal cerebral perfusion include acute ischemic stroke, subarachnoid hemorrhage, and traumatic brain injury. All these pathologies have the possibility of being helped by trigeminal nerve stimulation. Furthermore, there appears to be a highly significant inverse relationship between CBF and the development of white matter hyperintensities (WMH). In other words, poor cerebral perfusion predicted later leukoaraiosis (another term for WMH) while good CBF decreased the likelihood of its development. WMH are manifestations of brain damage from small vessel disease that, when present en masse, increase risk for cognitive impairment and dementia as well as other brain pathologies.

New advances in brain magnetic resonance imaging (MRI) studies are showing “pre- visible” changes in white matter regions of the brain that precede the appearance of recognizable WMH. This transitional pre- visible disease state is characterized by interstitial fluid mobility and water content and may be reversible by improving perfusion. Later changes include demyelination and axonal damage, which may be irreversible, leading to vascular cognitive impairment and dementia. Thus, attacking the disease process at an earlier stage by enhancing CBF, such as through trigeminal stimulation, is critical.

VIII. Face Desirable Location For Targeted Thermal- and/or Hydro- Therapy

The face versus the body may be a more desirable target of such thermal stimulation of skin (cutaneous) sensory nerve endings, because: the face is highly innervated; face skin reacts more strongly and faster than body skin in response to thermal stimulation; face skin feels cold, heat, and/or pain more intensely than body skin; facial and/or cranial nerves are wired directly to the brain versus body nerves which are wired to the spinal cord; a high density of facial skin nerve endings compared to many other parts of the body; and/or that nerve signals have a shorter distance to travel for facial and/or cranial nerves versus body nerves.

Additionally, thermally treating the (human) body (wherein “body” may be from below the neck) and not the face (or both the body and the face together) may have disadvantages versus just thermal treatment of the face only, because thermally treating the body and not the face (or both the body and the face together) is more likely to result in hypothermia or heat exhaus- tion/stroke because the entire body is being cooled/heated as compared against just thermally the face only, wherein only the face is being cooled/heated.

The entire body has both more mass and more surface area as compared to just the face. Thus, thermally treating the body and not the face (or both the body and the face together) may have disadvantages versus just thermal treatment of the face only, because thermally treating the body and not the face (or both the body and the face together) requires more energy to cool/heat that entire body as compared against just the face only, because of the larger amount of mass and surface area. Similarly, because the body is so much larger than the face, the size of the equip- ment for cooling/heating the body is much larger than equipment for cooling/heating just the face, which has less mass and less surface area. Thus, there may be scenarios where cooling and/or heating only the head, the face, or a portion thereof and not cooling and/or heating the remainder of the subject’s body may be desired.

IX. Health Benefits of Hydrotherapy

There are a multitude of documented and purported benefits for hydrotherapy, such as, but not limited to: promotion of physical health (cardiovascular, endocrine, neurological, and/or immune); fortification of mental health and sense of wellbeing; aesthetic enhancement; rehabilitation, recovery, and/or physical therapy; disease treatment; disease prevention; portions thereof; combinations thereof; and/or the like.

Psychological benefits of hydrotherapy have also been well-established. Recovery from mental fatigue has been specifically described following immersion in water of a mild temperature. Enhanced relaxation, quality of life, and relief from mental stress and/or depression have also been characterized and documented.

A study on thermoneutral water immersion demonstrated its ability to improve cardiac output at a specified oxygen consumption level. Relative hyperperfusion of peripheral tissue was a natural consequence of this process. When subjects engaged in exercise immersed in water were compared to subjects exercising out of water, the study authors found that cardiac output increased by 50% due to water immersion, which amplified further when the temperature of the water was lowered. Both greater stroke volume and decreased peripheral resistance during water immersion were responsible for boosting cardiac output, enhancing overall blood flow to the tissues of the body.

One study investigated the effects of water immersion on cerebral perfusion. The study authors enrolled nine young and healthy male (human) subjects and subjected them to normo- thermic water immersion up to the level of the right atrium. This raised multiple physiologic measures of cardiovascular transport and aerobic respiration, including mean arterial pressure, cardiac output, and end-tidal carbon dioxide, and enhanced cerebral blood flow velocities in the middle and posterior cerebral arteries at the same time. These changes disappeared when water immersion stopped. This study shows the potential impact water immersion might provide to improve cerebrovascular as well as cardiovascular and respiratory health.

A. Warm Water Immersion

The potential benefits of vasodilation due to warm water immersion (WWI) cannot be overstated. Dilation of the vasculature leads to improved blood flow, tissue perfusion and oxy- genation. In a group of young women, “passive heating” via hydrotherapy resulted in higher middle cerebral artery velocity and overall cerebrovascular conductance. The potential neurological benefits of this finding are enormous, particularly for patients suffering from stroke, or other cerebrovascular disorders.

One study measured an increase in serum levels of Brain-Derived Neurotrophic Factor (BDNF) following a 20-minute warm water bath. BDNF is a protein chemical messenger that has been linked to the proliferation, growth, differentiation, and maintenance of neurons. Regular warm water immersion (WWI) hydrotherapy could stimulate neurogenesis (creation of new neurons) and even reduce risk of dementia and cognitive decline. A decrease in cortisol levels was also observed, correlating with patient reports of reduced stress and an overall sense of wellbeing associated with hydrotherapy.

Interestingly, the trigeminal ganglion CGRP intercellular signaling pathway involves BDNF. Neurons within the trigeminal ganglion closely communicate with surrounding satellite glia cells via calcitonin gene-related peptide (CGRP) signaling. The glial cells release BDNF, which might play a role in a positive feedback loop to increase production of CGRP and promote nociceptive transmission through a tyrosine kinase (TrkB) receptor signaling pathway. This link between trigeminal ganglion intercellular communication and BDNF production suggests that hydrotherapy applied to the (human) face might also increase BDNF levels through this CGRP intercellular signaling pathway.

A 20-minute daily foot bath in warm water (41 degrees Celsius [106 degrees Fahrenheit]) in a group of elderly subjects resulted in a 22% reduction in the prevalence of sleep disorders. Given the prevalence of sleep disturbances in this population, these results are quite remarkable. The non-pharmacological nature of hydrotherapy makes it an ideal intervention to minimize polypharmacy (which can also adversely impact the geriatric population).

A review article evaluated nine (9) studies on the effects of WWI, which included multiple studies that investigated its impact on cardiovascular perfusion. These studies showed that WWI was able to circumvent the ischemic effects of vascular disease through vasodilation. Another pattern observed in subjects following WWI was reactive hyperemia, which is a phenomenon of enhanced blood flow that occurs as a compensatory response to a transient reduction or occlusion of blood flow. By lowering vascular resistance, reactive hyperemia enhances cardiopulmonary function. This phenomenon is frequently seen following exercise. In this way, the physiologic effects of WWI mirror the cardiovascular benefits of working out. An investigation of the impact of warm water immersion (or cycling) on cardiorespiratory fitness yielded impressive results. Those researchers designated two experimental groups: warm water immersion in a 42 degree Celsius (108 degree Fahrenheit) bath vs. cycling aerobic exercise. Both groups engaged in their respective activity for 30 minutes, 3 times per week over the course of 2 months. At the end of the study period, both groups experienced increases in both cardiorespiratory fitness (VC max) and brachial artery flow-mediated vasodilation, as compared to baseline measures (p < 0.05). The authors concluded that “passive heat training” could be a useful adjunct to cardiovascular exercise.

Of note, a separate group of investigators found increased levels of oxyhemoglobin (oxy- Hgb) in healthy human subjects that underwent a warm water foot bath. This improvement in the oxygenation of blood hemoglobin followed a dose-response, with more pronounced elevations in oxy-Hgb levels correlating with greater increases in water temperatures (38, 40, and 42 degrees Celsius [100, 104, and 108 degrees Fahrenheit]). Not only is more blood able to reach tissue (secondary to blood vessel dilation), but that blood can carry greater amounts of oxygen once it arrives.

These findings are consistent with results from another study investigating the impact of warm water immersion on various markers of cardiovascular health. Here, a group of healthy, young (albeit sedentary) subjects underwent WWI for 30 minutes per day, 3 times per week for 8 weeks. In comparison to the control group that underwent immersion in isothermal water, WWI was associated with reduced blood pressure and decreased carotid artery atherosclerosis and stiffness. Furthermore, WWI subjects exhibited elevated flow-mediated vasodilation (in comparison to isothermal controls).

The reduction in carotid artery stiffness from WWI extends peripherally. Research found a decrease in cardio-ankle vascular index, a measure of peripheral arterial atherosclerosis, following a warm water foot bath in healthy women between the ages of 29 and 60, suggesting less arterial stiffness and enhanced peripheral blood flow. Another study examined the effects of a 5- minute WWI up to heart level on a group of 10 men between the ages of 27 and 57; and that study found significant acute reductions in both peripheral and aortic arterial stiffness as well as enhanced perfusion of the coronary arteries (the arteries supplying blood to the heart). These improvements in widespread vascular health outcome measures collectively support the use of hydrotherapy to promote cardiopulmonary health and enhance cerebrovascular and peripheral vascular perfusion. The benefits of WWI extend to metabolic health and glucose control. One study demonstrated an ability of WWI to lower fasting blood glucose and insulin level in a group of sedentary overweight adults after repeated immersion in water heated to 39 degrees Celsius. Release of an acute inflammatory marker (IL-6) was also triggered by WWI leading to a paradoxically longterm anti-inflammatory effect.

B. Cold Water Immersion

Cold water immersion (CWI) has been associated with improvements in stress management, pain management, metabolism, attention, cognition, and/or overall mood. Cold water exposure activates specific nuclei within the reticular activating system (such as the locus coeruleus and raphe nuclei) resulting in a general state of alertness as well as a greater capacity of the central nervous system to recruit motor neurons. These systemic and functional effects can be attributed to the impact of CWI on the human sympathetic nervous system. Indeed, an increase in heart rate, blood pressure, metabolism, and peripheral catecholamine levels have been observed with CWI.

Like with WWI, there is evidence that CWI increases BDNF expression. A study published in 2013 evaluated the effects of cold-water swimming on chemical signaling in the brains of experimental rats. The study authors specifically analyzed the expression of different neuro- trophins (a general term for neuronal growth factors), including BDNF, within the hippocampus of the brain, the brain’ s memory center. Cold water swimming increased hippocampal BDNF expression relative to controls.

An increase in heart rate variability (the variation in heart rate due to adjustments in autonomic activity) can be observed during cold water hand immersion. Heart rate variability is a marker of cardiovascular adaptability and health. In comparison to hot water hand immersion (at significantly high temperatures of 48 degrees Celsius [118 degrees Fahrenheit]), individual pain tolerance with higher reported pain thresholds was seen during hand CWI. This is likely due to both decreased nerve conduction velocity in addition to diminished pain perception associated with high levels of sympathetic activation. Indeed, one study determined that local application of cold temperature induces an analgesic effect via reduction in measured nerve conduction velocity and inhibition of nociceptive receptor sensitivity.

One study made an impressive discovery regarding the release of chemical messengers during cold water exposure. They found that cold water immersion of the human body resulted in a 250-500% increase in circulating levels of catecholamines such as epinephrine, norepinephrine, and dopamine. Cold-induced sympathetic activity promotes the release of norepinephrine both peripherally (from the adrenal glands) as well as within the central nervous system (CNS), most notably at the locus coeruleus. Increased levels of circulating norepinephrine are also accompanied by elevated beta-endorphin. Notably, there is an absence of a concurrent increase in the stress hormone cortisol. This combination of stress hormones (catecholamines without cortisol) produces what Nobel prize winner Hans Selyer described as ‘eustress,’ during which one experiences heightened energetic state without a concurrent degree of anxiety or other negative mental impact.

One study of young healthy men found that those who experienced cold water immersion for at least 11 minutes per week saw an increase in brown fat thermogenesis. This translated to a compensatory increase in core body temperature and a subsequent boost in their basal metabolic rate. The elevation in core body metabolism has both acute and long-term features. Immediately upon entering the water and during CWI, the body will attempt to generate heat to compensate for the cold environment through shivering. However, following repetitive, chronic exposure to cold water, the human body will increase its stores of brown fat. This type of adipose tissue is literally shaded brown due to an increased number of mitochondria within individual cells. The mitochondria produce an uncoupling protein which decouples the proton (positively charged hydrogen ion) gradient created to produced chemical energy in the form of ATP and instead releases energy in the form of heat.

It is the increase in mitochondrially-dense brown fat stores (typically located beneath the clavicle, surrounding the heart and upper back) that requires more calories for maintenance (resulting in an increased metabolism on a long-term basis). Not only does CWI increase brown fat stores, but elevated norepinephrine, in fact, targets receptors on less metabolically active “white” adipose tissue to transform them into more metabolically active brown adipose tissue (BAT). The mitochondrial uncoupling that occurs in brown fat makes individual mitochondria less efficient at producing energy but also protects mitochondria and their associated cells from the damaging effects of reactive oxidative species, aka free radicals. Mitochondrial health is optimized in brown fat, while total available energy in the tissue increases due to the increase in mitochondrial number from mitochondrial biogenesis, the production of new healthy mitochondria. The molecular mechanism underlying the induction of mitochondrial biogenesis following CWI was elucidated from studies investigating the effects of leg CWI after exercise. These studies found that CWI upregulated the gene expression of peroxisome proliferator-activated receptor y coactivator- la (PGC-la), a gene-regulating protein. By modifying gene activity, the regulatory protein induces vascular and metabolic changes, including exercise-induced mitochondrial bio- genesis, to enable organisms to meet the demands of exercise. The upregulation of PGC-la was found to extend beyond the cold water exposed limb, implying that a systemic (whole body) response occurs, which might be accomplished by catecholamine activation of AMP-activated protein kinase (AMPK). These mitochondrial effects have been shown to persist after multiple rounds of CWI. Leg CWI demonstrates that limited exposure to cold water to specific body part can have health benefits for the entire body. There is evidence suggesting that adaption to CWI and other cold exposures is centrally directed by the brain. This enables a coordinated wholebody response that could be leveraged to promote health by only using CWI on less than the whole-body.

Another study measured biological indicators of metabolic and cardiovascular health in a group of healthy young men immediately following immersion in water at various temperatures (32, 20, 14 degrees Celsius [90, 68, 57 degrees Fahrenheit]). As a point of reference, baseline (human) body temperature is 37 degrees Celsius (98.6 degrees Fahrenheit). Immersion in water at 32 degrees Celsius produced a somewhat calming effect (as indicated by an 11% and 15% decrease in blood pressure and heart rate, respectively). This parasympathetic response was paired with a 24% decrease in cortisol, a stress hormone. A significant increase (107%) of diuresis (excretion of bodily fluids) was also observed. In 20-degree Celsius water, an increase (93%) in metabolic rate was noted. This effect became even more pronounced for the group immersed in colder water (14 degrees Celsius): an impressive 350% increase in metabolic rate was measured, with resultant increases in heart rate and blood pressure, both systolic and diastolic (by 5%, 7%, and 8%, respectively). The boost in metabolism was accompanied by a 530% increase in norepinephrine levels and a 250% increase in Dopamine. This surge of catecholamines was not paired with a concurrent increase in cortisol, consistent with the physiologic state known as eustress. Increased metabolism and an improved overall mood were found to be associated with cold water immersion (CWI), as reflected by the biomarkers listed above.

An interesting physiological and biochemical phenomenon observed with CWI is increased minute ventilation (respiratory rate), decreased end tidal CO2 levels, and cerebral vasoconstriction. These changes occur as part of a cold shock response (CSR) when someone is initially exposed to CWI, which can cause symptoms of dizziness. However, the CSR can be partially offset through leg exercise (kicking) begun 30 seconds after entering the water. Furthermore, another study showed that providing detailed instructions on suppressing reflex hyperventilation before CWI could prevent any meaningful decrease in cerebral blood flow velocity even in cold water naive participants. The CSR might seem like a drawback, but in fact, there is evidence that the limited stress provided by CWI can be used to optimize physiologic function and thus combat the negative effects of injury, a process known as hormesis. One study demonstrated that rats preconditioned with cold water swimming suffered less cognitive impairment than control mice following experimentally induced traumatic brain injury (TBI). Cognitive function was assessed using the Morris water maze, an evaluation where a rodent is taught to find a submerged platform in repeated trials. The neuroprotection demonstrated through preserved cognitive functioning was accompanied by an increase in the number of circulating endothelial progenitor cells (blood vessel precursor cells) and by enhanced angiogenesis (growth of new blood vessels) in the hippocampus (memory center) of the preconditioned rats.

One study investigated the effects of cold-water facial immersion on cerebral perfusion as measured by middle cerebral artery mean flow velocity (MCA Vmean). The middle cerebral artery (MCA) is one of the major arteries to the brain. Nine trained divers (all male) were evaluated during exercise, apnea, and facial immersion in 10 degree Celsius (50 degree Fahrenheit) water. Facial immersion in cold water was shown to enhance MCA Vmean independent of carbon dioxide elevation (which also increases MCA Vmean).

CWI of the (human) face induces a demonstrably powerful parasympathetic response, which could be mediated by the paratrigeminal nucleus interconnections with the vagus nerve, and the communication between trigeminal sensory information and carotid baroreceptors, that augment vagal outflow. This stimulation of the parasympathetic nervous system by CWI resembles the mechanism of action of the vagus nerve stimulator (VNS), which has been used in the treatment of thousands of people with drug-resistant epilepsy and depression since 1997 and 2005, respectively. Thus, facial CWI, provided by thermal delivery devices, systems, and/or methods of use as taught herein, could enable a more natural, simpler, safer, and less expensive way to stimulate the vagus nerve.

Regular winter swimming has been associated with improvements in negative mood state, muscle tension, fatigue, and even memory. For swimmers suffering from either fibromyalgia or rheumatism, regular cold-water immersion improved associated pain symptoms. There are also purported immune benefits associated with cold exposure. Following immersion in 18-degree Celsius (64-degree Fahrenheit) water, increased circulating levels of leukocytes, granulocytes, and natural killer (NK) cells were measured.

A studies review analyzed 17 small trials that included a total of 366 (human) subjects to evaluate the benefit of CWI in preventing and treating muscle soreness after exercise. Those au- thors concluded that there is evidence that CWI decreases delayed onset muscle soreness following exercise compared to rest or no intervention. Beneficial effects of CWI were seen at 24 hours, 48 hours, 72 hours, and 96 hours following exercise.

A study evaluated the effects of CWI on different inflammatory markers and hormonal levels as a way of trying to elucidate its analgesic and anti-inflammatory properties. The inflammatory markers evaluated included the interleukins, IL-l-beta and IL-6, and tumor necrosis factor (TNF) alpha, and the hormones assessed included plasma adrenocorticotropic hormone (ACTH), cortisol, and the catecholamine hormones epinephrine and norepinephrine. This study authors evaluated a group of 10 healthy women subjected to winter swimming at a water temperature of 0-2 degrees Celsius three times per week for a duration of 12 weeks. These study authors found a reduction in plasma ACTH and cortisol during weeks 4-12 of CWI compared to the first week, which they attributed to habituation. While epinephrine remained unaffected, CWI boosted norepinephrine levels by 2 to 3 -fold. These findings again demonstrate a eustress response. Cold exposure did not alter levels of any of the inflammatory markers. Given the positive correlation between CWI and norepinephrine levels, researchers hypothesized that norepinephrine may be responsible for the pain-relieving effects of cold exposure.

A study investigated the effects of CWI on young, healthy undergraduate students. After filling out a mood profile survey called the Profile of Mood States (POMS) questionnaire, 42 students were exposed to immersion in cold sea water at 13.6 degrees Celsius while 22 students served as controls. Participants, both in treatment and control groups filled out the POMS again following the intervention. The study authors found a significant improvement in mood in the CWI group compared to baseline. CWI reduced negative emotions and elevated positive emotions. No improvement was seen in controls when they repeated to questionnaire. In fact, the control droop scored higher on levels of depression compared to baseline.

The release of dopamine from cold exposure induced by CWI is another key human physiologic response. Very brief durations of cold exposure can result in persistent dopamine elevations that boost mood, energy, and focus. Numerous disease processes involve dopamine derangements, such as Parkinson’s disease, substance abuse, disorders, and ADHD. There is strong potential that CWI might provide benefit in these conditions.

Elevated serotonin levels are also associated with CWI. Along with norepinephrine and dopamine, serotonin plays a central role in mood and well-being. Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are two major classes of antidepressant medications. CWI has been shown to boost serotonin levels by reducing in- flammatory signaling. Inflammatory cytokines can trigger depressive symptoms, including poor mood, low energy, and social isolation. A particular inflammatory cytokine called indoleamine 2,3-dioxygenase (IDO) breaks down tryptophan, a precursor to serotonin. Thus, induction of IDO from pro-inflammatory cytokine signaling lowers serotonin levels, which may promote the development of depressive symptoms. This molecular mechanism was identified in experimental rats that expressed depressive behavior. After exposure to cold water from swim training, the rodents’ release of IDO fell, and their depressive symptoms decreased. In this way, CWI might also work in humans to counteract inflammation-induced depression.

There is also evidence that the hypothalamic hormone oxytocin, which is known for its anti- stress effects, might also play a key role in mediating health benefits from CWI. Oxytocin may promote thermogenesis by increasing brown adipose tissue (BAT) activity via the sympathetic nervous system, which is regulated by the hypothalamus. A preclinical study showed that experimental mice upregulated oxytocin in their brains in response to both short and long-term cold exposure. Additionally, correlation between genes involved in thermoregulation seems to depend on oxytocin receptor expression genes. In the absence of oxytocin activity, BAT metabolism and cold-induced thermogenesis are impaired, suggesting that oxytocin has a regulatory role in these processes. Like norepinephrine, oxytocin has the capacity to “brown” white adipose tissue (WAT), which has been demonstrated in inguinal WAT, with associated benefits in fighting obesity and poor metabolic health. Oxytocin may influence other pathways involved in BAT activity, including alpha-melanocyte stimulating homone (a-msh), endocannabinoids, and steroidogenic factor 1 (SF1). It might also downregulate corticotropin releasing hormone (CRH) during adaptation to chronic stress. Studies suggest that oxytocin activity within the brain pertaining to cold adaptation occurs in the hypothalamus and the rostral medullary raphe, although other brain regions or peripheral sites may be involved. Several studies show that bone increases production of oxytocin following cold exposure, for example. Preliminary studies suggest that oxytocin (which can be induced by cold exposure, such as CWI) has far-reaching health benefits. It acts as a good serine protease dipeptidyl peptidase-4 (DPP4) inhibitor, a certain class of anti-diabetic medication that helps lower glucose levels. Research is showing that it may have cardioprotective effects mediated through the release of atrial natriuretic peptide and nitric oxide, which have cytoprotective (cell protective) functions and aid in reperfusion of ischemic heart muscle. Oxytocin is also known to have both anti-inflammatory and pro-immune properties.

C. Homeostasis & Thermoregulation The human body possesses an internal thermostat that regulates the body’s core temperature on a generally 24-hour cycle. Approximately 2 hours prior to waking, one experiences their temperature minimum which then steadily increases into the afternoon (when maximum daily temperature is generally reached). Often a fluctuation of roughly 0.9 degrees Celsius (0.5 degrees Fahrenheit) is observed over the course of a given 24-hour cycle.

It is possible to ‘hack’ this daily cycle to achieve more alertness by experiencing cold early in the morning. This will signal your body to raise your core temperature due to the cold environment. The inverse is also true; warm water immersion prior to bed time assists with cooling down core body temperature and facilitating the transition into sleep, reducing sleep latency and enhancing sleep depth.

The palms, soles, and upper half of the (human) face are the three anatomical regions of the human body that are most effective at heat transfer. Whereas blood typically flows from artery to capillary to vein, these three regions generally lack capillaries. Known as AV As (arteriovenous anastomoses), the warm arterial blood flows directly into the venous draining system, allowing for significant heat to be given off or absorbed (depending on the surrounding environment).

X. Therapeutic Potential of Thermal and/or Hydro Therapy

The thermal delivery devices, systems, and/or methods of use as taught herein may be used for various therapeutic benefits from thermal therapies and/or from hydrotherapies. Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various therapeutic benefits with respect to one or more of the following medical disciplines: aesthetic medicine; cardiovascular; dermatological; ear, nose, and throat (otolaryngology); ophthalmology; neurological; psychological; endocrinology; rheumatology; portions thereof; combinations thereof; and/or the like.

A. Aesthetic Medicine (“Med Spa”)

Aesthetic medicine and/or “med spa” may include treatments for reducing, minimizing, and/or slowing down aging related skin problems, such as, but not limited to, skin wrinkles, agespots, and/or the like. Aesthetic medicine and/or “med spa” may include treatments for hydrating, moisturizing, exfoliating, lifting, plumping, adding/retuming elasticity, and/or the like with respect to human skin. Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various therapeutic benefits to human skin.

B. Cardiovascular Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various cardiovascular therapeutic benefits. The disease process of atherosclerosis causes structural changes in the vascular endothelium and inflammatory reactions that result in a narrowing of the vascular lumen and stiffening of the arterial wall due to buildup of fatty plaque. These pathological changes alter shear stress forces and cause deleterious hemodynamic fluctuations. Evidence of hydrotherapy’s vasodilatory effects, augmentation of arterial blood flow, and reduction in arterial wall stiffness, as demonstrated in research studies, supports the use of hydrotherapy as an adjunctive treatment for atherosclerosis.

Further, one study investigated 32 human patients with chronic congestive heart failure (CHF) secondary to dilated cardiomyopathy who underwent treatment with WWI hydrotherapy (hot water bath) at 41 degrees Celsius (106 degrees Fahrenheit) for 10 minutes. Improvements in cardiac function were observed, including enhanced cardiac and stroke indices and reduced systemic vascular resistance (p < 0.01). Mitral regurgitation (abnormal backflow of blood through the mitral valve) also improved both while the subject was bathing and 30 minutes afterwards. The above findings were further supported by an echocardiographic study of 18 elderly human patients with congestive heart failure (CHF) where the researcher’ s observed improvement in biventricular systolic and diastolic function associated with warm water immersion. WWI was well tolerated by this patient population across the 8-week study period.

C. Dermatological

Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various dermatological therapeutic benefits.

An 8-year observational study of over 14,000 patient records investigated the effect of hydrotherapy on atopic dermatitis and psoriasis. Following 3 weeks of daily hydrotherapy, both the SCORing Atopic Dermatitis (SCORAD) and Psoriasis Area and Severity Index (PASI) clinical outcome measures demonstrated a statistically significant improvement.

In a study of over 800 cases of pediatric atopic dermatitis, the authors reported a clinically and statistically significant improvement in SCORAD outcomes in patients aged less than 16 years. The clinical improvement was especially pronounced in those with severe disease and in patients less than 4 years of age. According to the study authors, hydrotherapy was well tolerated, and no relevant adverse effects were reported. Eighty-five percent (85%) of young people aged 14 to 25 develop acne, and 20% of all adults suffer from the condition, who could benefit from the therapeutic effects of hydrotherapy on the face (or other regions of skin with acne).

A group of Swiss clinical researchers investigated the benefits of 2-3 weeks of hydrotherapy utilizing hot spring water, waterjets, and hydro-pressure on 31 patients suffering from skin bums. It was observed that the skin was more homogenous in structure, color, and viscoelasticity with diminished pruritus following hydrotherapy intervention. These results were “permanent” if hydrotherapy was administered for 3-6 months.

D. Ears, Nose, Sinus, and/or Throat (Otolaryngology)

Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various ears, nose, sinus, and/or throat (otolaryngology) therapeutic benefits. One study found a significant symptomatic benefit in nasal symptom scores in patients with allergic rhinitis treated with steam inhalation at a temperature of 42 to 44 degrees Celsius compared to baseline with a trend towards improvement in total nasal airflow. Another study evaluated the effects of daily nasal saline irrigation, daily steam inhalation, or both, versus usual care in the treatment of patients with chronic or recurrent sinusitis in a randomized controlled trial that enrolled 961 (human) patients who were randomly assigned to each of the four groups. Benefit was determined using the Rhinosinusitis Disability Index (RSDI) questionnaire, which was taken at baseline (871 were completed) and then after three months of intervention (671 of the initial 871 questionnaires were completed). RSDI scores significantly improved in groups with nasal irrigation compared to those without, which was sustained at six (6) months. A benefit found from steam inhalation was fewer headaches.

E. Ophthalmology

Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various ophthalmological therapeutic benefits.

Warm water compresses draped over the eyelids are the current standard of care for blepharitis (aka “dry eye”). Immersion of the face in a warm water may produce similar or better benefits for patients suffering with blepharitis. One study enrolled 42 (human) patients and investigated three warm compress devices, one of which employed moist heat, the OPTASE™ Moist Heat Mask. Only the moist heat compress device was able to effectively lower pathogen levels in Demodex folliculorum blepharitis. Multiple studies have investigated the benefit of applying devices that use moist heat in the treatment of meibomian gland dysfunction, which is may be a significant cause of dry eye disease (DED). In the immediately above noted study for Demodex folliculorum blepharitis in which the authors investigated three warm compress devices, the moist heat compress device was able to significantly improve a composite score of meibum quality and ease of secretion from the meibomian gland. Another study investigated another moist heat device, the Blephasteam, in the treatment of meibomian gland dysfunction. The researchers enrolled seventy (70) patients of a Norwegian population. After six (6) months of treatment, the moist heat device was shown to significantly boost measures of meibomian gland function.

F. Neurological

Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various neurological therapeutic benefits.

A case report described six (6) (human) patients with trigeminal neuropathic pain (half of whom were diagnosed with trigeminal neuralgia) who underwent peripheral nerve stimulation, either of the trigeminal nerve directly or indirectly through the occipital nerve, which communicates with the trigeminal nerve at the level of the trigeminocervical nucleus. All patients experienced a large reduction in their reported facial pain at follow-up compared to their baseline pain levels.

Globally, the prevalence of headache disorder (symptomatic at least once in the past year) is estimated to be 47% (Headache disorders, WHO). The three (3) most common types of headaches are tension, sinus, and migraine headaches (in decreasing order of prevalence). According to the WHO Global Burden of Disease assessment, headache is the sixth leading cause of years lost to disability (YLD), placing a severe economic burden on both individuals and society overall (Headache disorders, WHO). The involvement of the fifth cranial nerve in headache has been thoroughly established, following the original postulation by Wolff in the 1940’ s. There are four (4) major types of headaches associated with the trigeminal nerve: tension headache, migraine, sinus headache, and cluster headache (part of a larger group of headaches known as trigeminal autonomic cephalgias).

An interesting prospective, observational, proof of concept study was conducted by ER physician, James Miner. Dr. Miner administered a 30-minute cold water head bath to treat 18 patients with a mean age of 29 years old who presented to the ER for treatment of headache. Patients met diagnostic criteria either for migraine headache, migrainous headache without meeting full diagnostic criteria for migraine, or tension headache. Dr. Miner’s approach utilized gradual water cooling from lukewarm to cold over a period of 15 minutes since sudden cold exposure from an ice bath or ice pack can acutely worsen headache. The ice bath consisted of porcelain container, similar to the basin of a sink, containing lukewarm water with an icepack at the bottom of the basin that gradually cools the water. The patient then lowered their head back into the water basin in a supine position (on their back) until their head was submerged just above ear level. Before therapy, headache pain was rated severe by ten (10) patient and moderate by eight patients. After 30 minutes, the median headache pain level of all the study participants dropped nearly 20 points on a 100-point scale, and nine (9) patients rated their pain level as mild. An additional 30 minutes of cold-water immersion for a total of 60 minutes had only modest effects (median pain level dropped another two points and one more patients rated their headache pain as mild).

One study assessed how daily nasal saline irrigation, daily steam inhalation, both hydrotherapies, or usual care affected patients’ symptoms with chronic or recurrent sinusitis. The authors conducted a randomized controlled trial that enrolled 961 patients who were randomly assigned to each of the four groups. Benefit was determined using the Rhinosinusitis Disability Index (RSDI) questionnaire, which was taken at baseline (871 were completed) and then after three months of intervention (671 of the initial 871 questionnaires were completed). Both nasal saline irrigation and steam inhalation were linked to less sinus headaches. Also, the application of a warm (moist) washcloth to the face is frequently recommended by healthcare professionals for relieving of sinus headache and congestion.

A study evaluated the application of non-invasive vagus nerve stimulation (nVNS) as a means of reducing the frequency of cluster headache. Ninety-seven (97) cluster headache (human) patients were randomly assigned to standard of care (49) or nVNS (48). After four (4) weeks of treatment, the nVNS group had significantly fewer headaches per week compared to compared to the control group. Furthermore, a significantly higher percentage of subjects in the nVNS group experienced a more than fifty percent (50%) drop in headache frequency compared to the control group. As mentioned above in the anatomy discussion, the trigeminal nerve has interconnections with the vagus nerve through the paratrigeminal nucleus and facial immersion in cold water may be a more efficient, safe, and effective way of stimulating the vagus nerve. Therefore, the thermal delivery devices, systems, and/or methods of use as taught herein may produce similar or better effects to nVNS with even less possibility of having side effects. Migraine headache is associated with several autonomic symptoms. A growing body of literature supports that dysfunction of the autonomic nervous system is linked to the pathophysiology of migraine. For this reason, thermal therapies may have benefits for treating migraine patients. Thermal hydrotherapy was studied as a non-pharmacological adjunct (conventional therapy versus conventional therapy PLUS hydrotherapy) in forty (40) (human) patients suffering from chronic migraine. Patients receiving hydrotherapy placed an arm and foot in a hot bath (39-43 degrees Celsius [103-110 degrees Fahrenheit]) while simultaneously receiving an ice massage to the scalp. Such thermal hydrotherapy was administered for twenty (20) minutes, daily for forty- five (45) days. At the end of the treatment period, the group receiving conventional therapy plus the thermal hydrotherapy experienced a decrease in both the frequency and intensity of headaches.

Four decades ago, preclinical research showed that cooling laboratory rats to 30 degrees Celsius achieved by partial immersion in a water bath significantly preserved beam balance skills following experimentally induced traumatic brain injury (TBI) compared to normothermic controls. There was a tendency toward less impairment of balance skills after cooling to 33 and 36 degrees Celsius.

More recent preclinical research on laboratory rats demonstrated that preconditioning with cold water swimming can preserve cognitive function (assessed using the Morris water maze) following experimentally induced traumatic brain injury (TBI). This is likely due to a hormesis response, in which a time limited mild to moderate stressor leads to changes in gene and protein expression that optimize physiologic function and protect against injury. In this study, the preservation of cognitive function was accompanied by enhanced hippocampus angiogenesis and proliferation of circulating endothelial progenitor cells.

Research on stimulation of the trigeminal nerve is also demonstrating its potential to alleviate damage from traumatic brain injury (TBI), specifically its ability to impact so-called ‘secondary injury’ from ischemia and hypoxia that occurs after the initial head trauma. Trigeminal nerve activity can improve cerebral perfusion on multiple levels, including activation of the rostral ventrolateral medulla, which elevates blood pressure, as well as inducing cerebrovasodilation via trigemino-cerebrovascular and trigemino-parasympathetic interactions. One study investigated the effect of trigeminal nerve stimulation (TNS) on cerebral blood flow (CBF) and brain oxygen tension (PbrO2) following experimentally induced TBI in laboratory rats. The study authors hypothesized that trigeminal nerve stimulation (TNS) would lessen the damage from secondary injury. A controlled cortical impact was delivered to the rats’ brains and then the rats received TNS for one (1) hour following brain injury (TBI). When compared to a TBI group without TNS, the TBI group with TNS showed significant elevations in systemic blood pressure, CBF, and brain oxygen tension (PbrCh) during the hyperacute phase of TBI. The TBI plus TNS group showed additional positive findings compared to the TBI group without TNS, including less brain edema, disruption of the blood brain barrier, and lesion volume, and decreased levels of TNF-a and IL-6 cytokines (inflammatory signals) in the brain neocortex. Overall, the results of this study suggest that TNS could have powerful neuroprotective effects following TBI. Importantly, the improvement in CBF is not merely due to elevation in mean arterial blood pressure (MAP) since CBF rises much more steeply than MAP. Cerebral vasodilation is playing a critical role in VNS -induced enhancement of cerebral perfusion.

The benefits of trigeminal nerve stimulation (TNS) extend to hemorrhagic shock. One study investigated the survival benefit from TNS in the setting of experimentally induced severe hemorrhagic shock in laboratory rats by withdrawing their blood to dramatically lower their blood pressure. When compared to vehicle rats that had trigeminal nerve electrodes placed but did not receive stimulation, the rats in the TNS intervention group showed dramatically prolonged short-term survival. At sixty (60) minutes post induction of severe hemorrhagic shock via blood withdrawal, the survival rate was ninety percent (90%) in the TNS intervention group versus zero percent (0%) in the vehicle group. A cooperative balance between sympathetic and parasympathetic nervous system activity was observed following TNS, which was assessed using heart rate variability. TNS prevented runaway sympathetic hyperactivity by counterbalancing it with parasympathetic tone and postponed hemodynamic decompensation in the absence of fluid resuscitation while improving CBF. Underlying the enhanced tolerance to central hypovolemia from exsanguination were sympathetically mediated low-frequency oscillatory patterns of systemic blood pressure and elevated levels of norepinephrine in the bloodstream induced by TNS. Another important effect found in the TNS group was a reduction in systemic inflammation compared to the vehicle group. This lowering of inflammation may have been a consequence of improved hemodynamics by avoiding hypotension and associated ischemia. Another explanation for depressed immunoreactivity would be that it results from the interaction between the trigeminal afferents and vagal parasympathetic fibers, which form a trigemino-vagal pathway. The dorsal motor nucleus (DMN), an important parasympathetic outflow center, and the nucleus tractus solitarius, which communicates broadly with preganglionic parasympathetic fibers, receive input from trigeminal nerve afferents that are activated by TNS. Then the DMN and nucleus ambigu- ous in the brainstem’s medulla oblongata are responsible for the parasympathetic output of this pathway.

Note, the thermal delivery devices, systems, and/or methods of use as taught herein may be used to stimulate the trigeminal nerve (e.g., via thermal delivery, electrodes, and/or chemical species included in a given immersion liquid).

A clinical trial of seventy-three (73) (human) patients suffering from multiple sclerosis (MS) investigated the efficacy of hydrotherapy in controlling MS related pain and associated symptoms. Thermal hydrotherapy was conducted in a swimming pool with the water temperature at 36 degrees Celsius (97 degrees Fahrenheit). Subjects were randomly assigned to experimental (thermal hydrotherapy) or control (relaxation exercise) groups. Following treatment for a period of twenty (20) weeks, the thermal hydrotherapy group scored significantly lower on reported pain measures (p < 0.028) compared to the baseline. Severity of disability, muscle spasm, depression, and fatigue all improved markedly with the thermal hydrotherapy.

Repeated cold exposure is known to boost the function of specific nuclei within the reticular activating system (such as the locus coeruleus and raphe nuclei), which results an alert, action-ready state. This can promote improved motivation, energy, and capacity for a quick motor response by recruiting motoneurons. Furthermore, stress induced by cold lowers serotonin levels all over the brain, except for the brainstem. A similar serotonin pattern is associated with decreased fatigue in animal models of exercise-associated fatigue. Cold exposure also raises opioid tone (beta-endorphin) and metabolic rate that could aid in lowering pain associated with muscle fatigue and hastening recovery of muscle function. Thus, cryo and/or hydro therapies may be used for treating chronic fatigue syndrome (CFS).

A research team led by Professor Giovanna Mallucci investigated how proteins produced during cold water immersion (CWI) might be used to combat the development of neurogenera- tive disease. What fueled her curiosity was the fact that various hibernating mammals, such as, bears, hedgehogs and bats, lose 23-30% of their synapses during the winter while hibernating but then recover these synapses when they wake up in the Spring. Professor Mallucci later conducted research on human subjects, winter swimmers, who already expose themselves to the extreme cold throughout the winter by swimming at the unheated open-air lido on Hampstead Heath in London. Her research team analyzed the blood of the winter swimmers in 2016, 2017, and 2018 to determine their levels of RBM3 (a cold-shock protein in the brain and a RNA binding protein) and compared them to the RBM3 levels found in a Tai Chi group who trained next to the pool but never actually entered it. All the winter swimmers experienced hypothermia, with core tem- peratures as low as 34 degrees Celsius (93.2 degrees Fahrenheit). A significant number of them had pronounced elevations of RBM3. Neither the hypothermia nor the rise in RBM3 was found in the Tai Chi group.

One study showed that laboratory mice who were subjected to cold exposure (6-18 degrees Celsius for 45 minutes) went through a similar process of synapse breakdown and recovery. These researchers identified cold-shock proteins in the brain, including the RNA binding protein, RBM3, which was found to play a key role in synapse repair. Unlike wild type mice, both prion-infected and 5xFAD (expressing 5 Alzheimer-linked mutations) mice were unable reestablish synaptic connections following cold exposure in tandem with a failure to upregulate RBM3 levels. When RBM3 expression was upregulated in the hippocampus, the prion-infected and 5xFAD mutant mice acquired the ability to regrow synaptic connections following cold exposure. RBM3 overexpression was neuroprotective in both mouse models of neurodegenerative disease, preventing neuronal loss, prolonging survival, and maintaining normal behavior. Randomized, controlled within-subjects crossover study investigated the impact of hydrotherapy on treatment of (human) children with a diagnosis of autism spectrum disorder (ASD) between the ages of 6 and 12. Subjects were randomly assigned to two groups, one of which received hydrotherapy between weeks 1 to 4, the other between weeks 5 to 8. The Child Behavior Checklist (CBCL) was completed at baseline and at weeks 4 and 8. The study authors found significant improvements following hydrotherapy compared to the control group in the subdomains of anxiety/ depression and internalizing problems, as well as in thought problems and attention problems. Intervention also significantly improved the total problems score with a large effect size. A systematic review meta-analysis was performed investigating the benefit of hydrotherapy in autism spectrum disorder (ASD) outcome. The study authors used search criteria that included affected individuals who were at a high functioning level and between the ages of 3 and 18. Measurements evaluating social interactions and behaviors were necessary for the study to be included in the analysis. Four studies met inclusion criteria. Study results showed that hydrotherapy intervention led to better overall social interactions or behaviors.

G. Psychological

Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various psychological therapeutic benefits.

Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various psychological therapeutic benefits to mood disorders, such as, but not limited to, anxiety and/or depression. Ten (10) minutes of warm water immersion in a whirlpool bath produced an overall feeling of well-being as well as a decrease in reported symptoms of anxiety as described in the DSM (Diagnostic and Statistical Manual of Mental Disorders). Immersion in a water bath with high levels of dissolved carbon dioxide bubbles (CO2) has been observed to elicit high parasympathetic activity in human subjects, commonly associated with a subjective feeling of calm.

EEG data supports a relaxation effect from warm water immersion (WWI). A study examining the benefit of thermal hydrotherapy after viscous fluid injections for osteoarthritis took EEG reads during WWI and found reduced relative power of alpha waves in frontal, temporal, and parietal areas. Chronic pain causes a person to be very focused on a painful limb and hydrotherapy may help to break free of that hyperattention. As a way of interpreting the EEG data, a study showed that engaging in a self-hypnotic technique to induce relaxation, called an autogenic exercise, resulted in an acute lowering of alpha wave percentage while theta percentage rose. One study compared the efficacy of hyperthermic baths (HTB) to a moderate-intensity physical exercise program (PEP) as add-on therapy to standard of care for the treatment of depression. The study authors enrolled 45 medically-stable (human) subjects suffering from moderate depression determined by Hamilton Depression Rating Scale (HAM-D) scores. Compliance was poor in the group randomized to participate in the PEP. Nevertheless, adjusted scores using a last-observation-carried-forward technique showed significantly fewer depressive symptoms in the HTB group compared to the PEP group as measure by HAM-D. Greater efficacy from HTB was also seen on a per-protocol analysis on a trend-level.

A double-blind randomized, controlled trial investigated the effects of whole-body cryotherapy on symptoms of depression in otherwise healthy (human) adults. Ninety-two (92) subjects between the ages of 20 and 73 who had been diagnosed with a depressive episode were enrolled. Depression levels were measured using the Beck Depression Inventory-II (BDI-II) and the Hamilton Depression Rating Scale (HAM-D 17). The group treated with cryotherapy showed significantly fewer depressive symptoms compared to the control group as measured by BDI-II and HAM-D 17.

One study compared the EEG alpha frequency power between a group of (human) participants with high mindfulness and low anxiety (HMLA) to a group with low mindfulness and high anxiety (LMHA) during a visual cognitive task, called the color Stroop test. In this test the word of a color is written in a different color, and the patient have to name the actual color not what is written. The HMLA group was found to have improved working memory capacity and accuracy. Because cold water immersion (CWI) enhances alpha frequency, CWI supports improving working memory and cognitive function while reducing anxiety.

One study evaluated the effect of outdoor swimming on mood. Sixty-one (61) (human) swimmers were compared to 22 controls who sat on the beach after a 10- week introductory outdoor swimming course. Mood was evaluated using Profile of Mood States and Short Warwick- Edinburgh Mental Well-being Scale questionnaires. Swimmers were found to have significantly larger declines in negative mood states, such as tension, anger, and depression, and greater improvements in well-being compared to controls at the end of the course. The authors also noted acute improvements in mood (increases in positive mood states and decreases in negative mood states) following swims.

A case report documents effective treatment of a 24-year-old woman suffering symptoms of major depressive disorder and anxiety with a weekly regimen of open cold-water swimming. She had received treatment for these disorders since the age of 17, and her symptoms were refractory to the antidepressants, fluoxetine and then citalopram. She started swimming after the birth of a child with the goal of getting off her medication and being free of symptoms. The patient reported acute improvement after each swim. Eventually she obtained a persistent improvement in mood and progressive decrease in depressive symptoms to the point where she was able to wean off her medication. She maintained her remission free from medication on one year follow-up.

Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various psychological therapeutic benefits to mood disorders, such as, but not limited to, additions and/or substance use (abuse) disorders. The Mayenne Centre in France applied hydrotherapy in their treatment of patients suffering from addictions for both addiction support therapy and prevention. An article described using hydrotherapy in treating a patient with addiction with positive results.

H. Endocrinology

Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various endocrine system (or portions thereof) therapeutic benefits. Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to at least partially treat diabetes.

A clinical trial investigating the acute and chronic effects of warm water immersion (WWI) on a group of sedentary, overweight adults discovered that chronic repeated WWI at 39 degrees Celsius decreased fasting glucose and insulin levels. Extracellular heat shock protein in the plasma also decreased in the setting of chronic WWI, consistent with a reduction in chronic inflammation. Acute WWI triggered elevations in IL-6 and improved nitric oxide (NO) bioavailability. IL-6, an acute inflammatory signaling molecule, is in fact a marker of future antiinflammatory activity in this clinical context. Interestingly, an acute inflammatory response from a time-limited physical stressor, such as exercise can lead to a prolonged anti-inflammatory reaction by triggering the release of anti-inflammatory cytokines, such as IL-1 receptor antagonist (IL- Ira) and IL- 10. This acute inflammation intensifies in the context of hyperthermia. NO is important for many biological processes, including uptake of glucose into tissues. These results support that long-term treatment with thermal hydrotherapy may prove to be a useful adjunct in a multifactorial approach to improve glucose metabolism, even in those with limited exercise capacity.

Cold water immersion (CWI) may improve metabolic health by stimulating the production of brown fat and the “browning” of white adipose tissue (WAT) through the induction of mitochondrial biogenesis (production of new, healthy mitochondria). Brown and beige fat promote metabolic health, improve glucose and insulin sensitivity, and defends against diabetes. In one study six men naive to cold exposure were subjected to cold temperature (10 degrees Celsius) for 2 hours 5 days per week for 4 weeks using a liquid cooling garment. After four weeks of the protocol, the study authors found that participants had a 45% percent increase in the volume of met- abolically brown adipose tissue (BAT), and BAT oxidative metabolism more than doubled. Another study analyzed the impact of cold exposure on weight loss and thus its ability to combat obesity (associated with insulin insensitivity and increased risk for diabetes) in healthy individuals with low BAT activity at baseline. Daily 2-hour cold exposure at 17 degrees Celsius for 6 weeks increased BAT activity and reduced body fat mass at the same time. To directly assess the metabolic effects of BAT activity on metabolic health in humans, another study evaluated the effects of BAT activation on whole-body glucose homeostasis and insulin sensitivity. The study authors recruited 7 BAT-positive men and 5 BAT-negative men who were comparable in age, BMI, and adiposity and subjected them to a thermoneutral environment or 5-8 hours of cold exposure. Significant improvements in whole body glucose clearance, plasma glucose metabolism, and insulin sensitivity accompanied by elevated resting energy expenditures were only found in the BAT-positive group.

I. Rheumatology Thermal therapies and/or hydrotherapies using the thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide various rheumatological therapeutic benefits, such as, but not limited to, treating fibromyalgia, various forms of arthritis, osteoarthritis, chronic ankle pain, and/or the like.

A warm- water based hydrotherapy intervention resulted in a 15% reduction in fibromyalgia related pain when administered over the course of 12 weeks. A systematic review on the management of Fibromyalgia Syndrome (FMS) concluded that “there is strong evidence for the use of hydrotherapy in the management of FMS” and highlighted positive clinical outcomes for pain, tender point count, and health-status.

One study investigated the capacity of cold-water immersion (CWI) to alleviate pain and associated symptoms due to gouty arthritis. They enrolled 76 (human) participants who were divided into two groups, one served as a control and the other was treated with CWI, consisting of exposure to 20-30 degrees Celsius for 20 minutes per day for 4 weeks. Compared to the control group and baseline evaluation, the CWI group scored significantly lower on measures of pain and improved on measures of joint mobility, physical activity, stress, anxiety, and quality of life after two weeks, which was sustained at 4 weeks. Depression scores were also reduced by the end of the study.

One study investigated whether hydrotherapy would provide additional benefit to a group of (human) patients with knee osteoarthritis receiving viscous fluid injections containing hyaluronic acid. A total of nineteen (19) patients were enrolled and randomly assigned to receive hydrotherapy or no additional treatment following their injections. Hydrotherapy treatment consisted of a green tea spa that was administered three (3) times per week for two (2) weeks. The study authors evaluated measures of pain, quality of life, and emotional status. They also took an electroencephalogram (EEG) reading to determine the relative spectral power of alpha waves. The Western Ontario and McMaster Universities osteoarthritis index (WOMAC) pain and function subscale scores were significantly improved compared to baseline in the hydrotherapy treatment group. A difference between the hydrotherapy and control groups was in a pain scale score where pain is rated by visual assessment according to a spectrum of cartoon faces with different facial expression (the visual analogue scale or VAS). Two weeks of hydrotherapy treatment also diminished the relative power of alpha waves in different brain regions, the frontal, temporal, and parietal areas, consistent with mental relaxation.

Deep breathing exercises are associated with a reduction in chronic ankle pain and enhance EEG alpha rhythm power in the occipital region after six weeks of treatment. During working memory and other cognitive tasks, alpha frequency increases in the prefrontal cortex, fronto-central and centro-parietal regions. Interestingly, alpha wave power is boosted by hand CWI in distinct ways depending on whether the water is painfully cold or merely cool, suggesting CWI helps alleviate chronic pain and enhance cognitive functioning. The effect was stronger when the water was colder.

XI. Conclusions

Hydrotherapy has been used since the time of the ancient Egyptians and ancient Greeks to promote health and well-being and is enjoying renewed appreciation after being largely relegated to the status of “alternative” medicine. For example, at least some potential benefits of hydrotherapy and/or thermal therapy, cold and/or warm liquid (water) immersion, may include: enhanced cerebral blood flow; improved peripheral blood flow; respiration health; cardiovascular health; greater release of brain-derived neurotrophic factor (BDNF), which has been referred to as “miracle grow” for the brain; more brown fat production with improved mitochondrial health; better metabolic health and glucose control; enhancing/improving sleep; improved mood, concentration, and cognitive function by boosting release of multiple neurotransmitters, including epinephrine, norepinephrine, dopamine, serotonin, and/or oxytocin. Hydrotherapy and/or thermal therapy could potentially have therapeutic application to overall health and wellbeing, as well as, numerous disease processes, such as, but not limited to, cardiovascular diseases; neurologic conditions, such as headaches; dermatologic conditions; and depression and anxiety. The thermal delivery devices, systems, and/or methods of use as taught herein, may be used to provide such hydrotherapies and/or thermal therapies.

Also, with respect to the human face in particular, at least some of the thermal delivery devices, systems, and/or methods of use as taught herein may provide hydrotherapies and/or thermal therapies directly to the face and thus leverage the unique neuroanatomical circuitry and vasculature of the face to promote health and well-being and/or treat various injuries, diseases, conditions, and/or disorders. The human face has several unique anatomical features. Facial sensory neurons communicate with the trigeminal ganglion (TG), which then communicates with the trigeminal nucleus in the brain. The TG exists outside the blood brain barrier (BBB) and thus provides easy access to the brain that could be conveyed through (facial) transdermal therapies that circumvent the BBB. Furthermore, a unique direct connection from facial sensory neurons to a nucleus in the brain, called the parabrachial nucleus, has been identified that delivers pain signals, and does not exist between sensory neurons in the body and the brain. In this way, the thermal delivery devices, systems, and/or methods of use as taught herein that may target the face, may be used to provide superior health benefits of hydrotherapy and/or thermal therapy more efficiently without some of the negatives of whole-body hydrotherapy, such as the difficulties in transporting and changing the temperature of large volumes of water, and the discomfort of exposing the entire human body to cold water.

Another key feature of the neuroanatomical circuitry of the trigeminal nerve is its connections with the vagus nerve at the level of paratrigeminal nucleus in the brain and though its interactions with the baroreceptors in the neck, which promote parasympathetic outflow. The thermal delivery devices, systems, and/or methods of use as taught herein that may target the face, may then be used to stimulate vagus nerve activity in a more natural, safer, and less expensive way compared to the vagus nerve stimulator. In addition, the trigeminal nerve plays a central role in the modulation of cerebral blood flow via three separate mechanisms, all of which enhance blood flow. Also, unique to the upper half of the (human) face and select areas of the body (e.g., palms and soles) is the presence of glabrous skin, which carries distinctive vascular structures called arteriovenous anastomoses (also known as AV As) that enable faster transfer of heat, either into or out of the body, as compared to regions of the human body without such AVAs. All these features make direct application of hydrotherapy and/or thermal therapy to the face ideal, which has now been made possible in a convenient and unique way by thermal delivery devices, systems, and/or methods of use as taught herein that may target the face.

Note, before invention of a “face soaking device,” a soaking-device 100, a handheld- thermal-device 3400, a handheld-thermal-device 3450, a whole head thermal delivery device 3500, face/head thermal delivery device 3600, face/head thermal delivery device 3700, and/or at least some of the thermal delivery devices 3911 described herein that may target the face 192 (collectively or individually referred to as “thermal delivery device(s) targeting the face”), there was not a good means for heating/cooling the face using an immersive temperature-controlled medium. In some embodiments, the “face soaking device” terminology may be face soaking device at least as substantially (mostly) shown and/or described in U.S. utility patent 10667990, U.S. utility patent 10449341, U.S. utility patent 10667991, U.S. utility patent 11154697, U.S. design patent D863575, U.S. design patent D863576, U.S. design patent D864403, U.S. design patent D889675, and/or U.S. design patent D916303; wherein the “face soaking device” may comprise a vessel (configured to hold an immersion liquid), a breathing apparatus, a headrest, a neck gasket (which provides a water tight seal at the front of the user’s neck but without discomfort or pain to the front of the user’s neck), and at least one heating and/or cooling means for heating and/or cooling the immersion liquid that resides within the vessel portion. Before the invention of the thermal delivery device(s) targeting the face (as discussed herein), a person might dip one’s face into a bowl of water at a given temperature. However, that had at least a problem that a rim of the bowl would dig into the soft tissue of the front of the person’ s neck, causing discomfort and/or pain. Additionally, a mere bowl of water had no integral and/or comfortable means for breathing while that face was underwater and submerged within the water of the given bowl.

Or before the invention of the thermal delivery device(s) targeting the face (as discussed herein), a person might place a hot or a cold damp/wet towel onto their face. However, such a towel very quickly loses its heat/cold and thus quickly becomes non-effective for facial thermal skin therapy. Additionally, if the towel is too wet, such a process may wet undesirable things, such as other parts of the person and/or the person’s surroundings. Or if the towel is too dry, it may too quickly lose its ability to heat and/or cool the face.

Or before the invention of the thermal delivery device(s) targeting the face (as discussed herein), a person might soak their entire body in a bathtub, hot tub, and/or jacuzzi of heated water. However, heating the entire body as opposed to just the face has drawbacks as noted above. Also, hot tubs (and many bathtubs) are often restricted to a maximum water temperature of 104 °F, which may be too cool of an immersion liquid to elicit a proper pain and/or neurotransmitter release response. Additionally, bathtubs can be difficult or awkward to cool, if cooling instead of heating is a desired therapeutic approach to be used. And use of just a bathtub for soaking just the face has the same problems as a bowl of water as noted above.

Or before the invention of the thermal delivery device(s) targeting the face (as discussed herein), a person might use a radiation source (e.g., a light source, such as, but not limited to, a lamp or the sun) to heat their face, with the radiation passing through the air and then into the face. Such a means could not be used to cool the face, often results in dry skin, may result in undesirable skin pigmentation, may result in undesirable skin freckles, may result in undesirable skin moles, may result in undesirable skin sunspots, may result in undesirable skin wrinkles, may result in undesirable skin sun damage, and/or may result in undesirable burns to the skin.

Or before the invention of the thermal delivery device(s) targeting the face (as discussed herein), a person might use heated or cooled blown air onto their face to heat/cool the face via wind, a blower, a fan, or the like. However, a problem with such an approach is that air is a comparatively poor conductor of heat/cool as compared to an immersion liquid like water and/or a skin safe liquid oil. Additionally, blowing such air over the face can lead to undesirable drying of the skin. Or before the invention of the thermal delivery device(s) targeting the face (as discussed herein), a person might use a sauna or steam air mixture to heat the entire body, including the face. However, heating the entire body as opposed to just the face has drawbacks as noted above. Air, even when mixed with steam, is a poor thermal conductor (as compared to water); hence, saunas routinely operate at a temperature of 195 °F whereas a hot tub might only operate at 104 °F, because water is such a better heat conductor than air with steam. And this heating means does not lend itself to a cooling means.

Further, liquids (e.g., water) in general are better a heat transfer than gasses (e.g., air). The thermal conductivity of water is twenty-four (24) times that of air, and the energy required to heat a given volume of water by one degree Celsius is 3,500 times that of air, the cooling power of cold water in terms of human deep body temperature is approximately three times that of cold air at the same temperature. Consequently, a given rate of heat loss can be achieved at a higher cool temperature, and with a narrower skin-environment temperature gradient in water, than in air. In other words, prior art thermal therapies that use air as the heat transfer medium are less efficient than the thermal delivery device(s) targeting the face (as discussed herein), that use an immersion liquid such as, but not limited to, water.

Or before the invention of the thermal delivery device(s) targeting the face (as discussed herein), a person might use a walk-in refrigerator or freezer to cool the entire body, including the face. However, cooling the entire body as opposed to just the face has drawbacks as noted above. This type of cooling means does not work for cooling just the face and not the body. Further, walk-in refrigerators or freezers use cooled air as the heat transfer medium within the air volume of the given refrigerator/freezer, which as noted above is not as desirable as using a liquid like water. And walk-in refrigerators or freezers will dry out the skin (as they generally operate at low humidities).

The thermal delivery devices targeting the face (as discussed herein) have solved all those problems. With the thermal delivery device(s) targeting the face (as discussed herein), heat and/or cold may be applied to skin of the face (and not the whole body), in a controlled manner, at a predetermined temperature, for a predetermined duration, while the user breathes normally with their face submerged in the immersion liquid via a breathing apparatus of the given thermal delivery device, without drying out the skin, and/or (optionally) with various additives, such as, but not limited to, light therapy, gas bubble therapy, vibration, and/or other ingredients e.g., chemicals) added into the immersion liquid. Thus, the thermal delivery device(s) targeting the face (as discussed herein) may be ideal thermal delivery device(s) for causing rapid and/or con- trolled brain neurotransmitter release by way of heating and/or cooling skin of the face, which in turn may be used to affect, change, treat, and/or reduce symptoms of a variety of medical conditions that benefit from release of brain neurotransmitters.

The thermal delivery device(s) targeting the face (as discussed herein), may also be used for topical face skin treatments and/or for administering (delivering) transdermal ingredients (chemicals/medications), wherein the topical ingredients and/or the transdermal ingredients may be dissolved and/or carried within the immersion liquid within the vessel portion of the given thermal delivery device targeting the face (as discussed herein) and thus delivered to facial skin in physical contact with the immersion liquid.

There is a need in the art for thermal delivery device(s) (such as, but not limited to, the thermal delivery device(s) targeting the face (as discussed herein) that are configured for and/or adapted to deliver heat and/or cold to specific, particular, and/or targeted portion(s)/region(s) of the skin of a living organism’s body, such, as, but not limited to, the face; a facial cheek; a head (cranium); entire body of the organism; a body but not a head of the organism; an appendage; a limb; a digit; a finger; a thumb; a toe; a torso; a chest; a leg; an arm; a hand; a foot; a portion thereof; a combination thereof; and/or the like of the organism. There is need in the art for a system wherein the thermal delivery device is used to heat and/or cool skin of the organism in a manner that produces neurotransmitters by way of thermal skin stimulation using the thermal deliver device. There is need in the art for a method of using the thermal delivery device to heat and/or cool skin of the organism in a manner that produces neurotransmitters by way of thermal skin stimulation using the thermal deliver device. There is need in the art for a method of thermal stimulating skin to produce neurotransmitters.

There is a need in the art for thermal delivery device(s), system(s), and/or method(s) that may provide for and/or enhance transdermal delivery of ingredients (e.g., chemical(s) and/or medication(s)). There is need in the art for a method of inducing a desired and/or intended outcome in a subject (living organism) by way of thermal stimulating some region of skin of that subject.

In some embodiments, the thermal delivery device may be a “face soaking device” as shown and described in U.S. utility patent 10667990 and its related patents. In other embodiments, the thermal delivery device may be a device other than such a “face soaking device.” In other embodiments, the thermal delivery device may be a device as shown and described herein such as, but not limited to, a soaking-device, a handheld-thermal-device, a whole head thermal delivery device, a face/head thermal delivery device, at least one of the devices shown and described in one of the U.S. provisional patent applications that this present (instant) U.S. nonprovisional patent application claims priority to, portions thereof, combinations thereof, and/or the like. In some embodiments, the subject may be a living human. In other embodiments, the subject may another type of living organism, such as, but not limited to, a vertebrate animal, a mammal, and/or a primate. In some embodiments, the portion may be a face, a head, or a portion thereof of the given subject. In other embodiments, the portion may be an entire body of the subject or some portion thereof. In some embodiments, the cooling and/or the heating of the portion (e.g., the face) may be sufficient to induce the desired and/or the intended outcome in that subject. In some embodiments, the desired and/or intended outcome may relate to: release of at least one type of neurotransmitter; trigeminal nerve stimulation; (indirect) vagus nerve stimulation; transdermal drug delivery; bypass of the blood-brain-barrier (BBB); aesthetic medicine; cardiovascular; dermatological; ears, nose, and throat (otolaryngological); ophthalmological; neurological; psychological; endocrinological; and/or rheumatological benefits to that subject. In some embodiments, the at least one type of neurotransmitter may be selected from: dopamine, noradrenaline [norepinephrine], serotonin, oxytocin, endorphins, portions thereof, combinations thereof, and/or the like.

In other embodiments, the thermal delivery device may be a soaking-device that may be used to soak a given body portion of a person (or other animal), such as, but not limited to, a face (or head) of the person, in an immersion liquid (such as, but not limited to, water). In some embodiments, the soaking-device may have a vessel (container / tub) configured to removably hold the immersion liquid. In some embodiments, the vessel (vessel portion) may be formed from a floor-and-sidewalls member, a front-panel, and a rear-panel. In some embodiments, the immersion liquid, the vessel, floor-and-sidewalls member, the front-panel, and/or the rear-panel may be warmed, heat, cooled, chilled, or combinations thereof. In some embodiments, beneath the vessel may be at least some insulation to slow temperature changes of the immersion liquid with re- spect to external ambient temperature located surrounding that given soaking-device.

In the following discussion that addresses a number of embodiments and applications of the present invention, reference is made to the accompanying drawings that form a part thereof, where depictions are made, by way of illustration, of specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and changes may be made without departing from the scope of the invention. FIG. 1A shows a front, top, and right-side perspective view of an overall assembled soaking-device 100, in use by a human user 190, with a face 192 of the user 190 immersed (submerged) within an immersion-liquid 1800 of a vessel of soaking-device 100. In some embodiments, when soaking-device 100 may in use as intended by user 190, such as is shown in FIG. 1A, a back-of-neck 193 may not be touching a neck-gasket 500 of soaking-device 100; whereas, a front-of-neck 197 may be in direct physical contact with at least some portions of neck-gasket 500 (flexible-member 501) of soaking-device 100. Compare for example, FIG. 1A to FIG. 5F. FIG. 1A shows back-of-neck 193 not touching neck-gasket 500; whereas, FIG. 5F shows front- of-neck 197 in direct physical contact with at least some portions of neck-gasket 500 (flexiblemember 501). One ear 199 of user 190 may be visible in FIG. 1A. A portion of this ear 199 of user 190 may be just partially visible in FIG. 5F.

Continuing discussing FIG. 1A, in some embodiments, soaking-device 100 may be configured to (temporarily) hold immersion-liquid 1800 (such as, but not limited to, water) above a floor-and-sidewalls 101 component, between the sidewalls of the floor-and- sidewalls 101 component and between a front-panel 103 and a rear-panel 105 of soaking-device 100. In some embodiments, the front-panel 103 and the rear-panel 105 may be opposing from each other, with a length of the floor-and-sidewalls 101 disposed between front-panel 103 and rear-panel 105. In some embodiments, because floor-and-sidewalls 101, front-panel 103, and rear-panel 105 may be configured to hold this immersion- liquid 180 without leaking, those particular components (parts) may collaboratively work together in forming a watertight (water proof) vessel configured to hold this immersion-liquid 180. Thus, the floor-and-sidewalls 101, the front-panel 103, and the rear-panel 105 may define a waterproof vessel (container) (for holding this immersion-liquid 180) that is open at its top as shown in FIG. 1A. See also, FIG. IB, FIG. 1C, FIG. ID, and/or FIG. 1H that also shows these configurations and/or arrangements of the floor-and-sidewalls 101, the front-panel 103, and the rear-panel 105 of soaking-device 100 that may form this waterproof vessel (container) that is open at its top.

In some embodiments, immersion-liquid 180 may also be referred to as a liquid because immersion-liquid 180 may be used to immerse (submerge) at least one body part, body portion, combinations thereof, portion thereof, and/or the like of the user 190. For example, and without limiting the scope of the present invention, this at least one body part, body portion, combinations thereof, portion thereof, and/or the like of the user 190 as shown in FIG. 1A may be a face 192 of user 190, a portion of face 192 of user 190, and/or a portion of a head 191 of user 190. Note, face 192 of user 190 may be at least partially shown in FIG. 17F and/or in FIG. 17G. In some embodiments, immersion-liquid 180 within this vessel of soaking-device 100 may be heated, cooled, chilled, combinations thereof, portions thereof, and/or the like.

In some embodiments, immersion-liquid 180 within this vessel of soaking-device 100 may have various predetermined additives added to the liquid (water), such as, but not limited to: salts, ions, minerals, electrolytes, chemicals, medicines, pharmaceuticals, botanicals, essential oils, fragrances, perfumes, soaps, surfactants, cleaners, moisturizers, cosmetics, shampoos, conditioners, combinations thereof, portions thereof, and/or the like.

In some embodiments, an animal 190 body part (or portion thereof) may be soaked within this immersion-liquid 180 that is being (temporarily) hold within the vessel portion of soakingdevice 100. In some embodiments, animal 190 may be selected from a vertebrate animal, a mammalian animal, a primate animal, or a human. In some embodiments, the body part of animal 190 may be selected from head 191, a face 192, a hand 195, a foot, an arm, a leg, combinations thereof, portions thereof, and/or the like. In some embodiments, reference numeral “190” may refer to the user of soaking-device 100 who is and/or intends to have a body portion soaked (immersed) within the vessel portion of soaking-device 100; wherein this user 190 may be selected from a vertebrate animal, a mammalian animal, a primate animal, or a human.

FIG. 1A also shows concurrent use of a breathing-apparatus 1700. In some embodiments, when a mouth and/or a nose of user 190 may be submerged (immersed) within immersion-liquid 180 of the vessel portion of soaking-device 100, the breathing-apparatus 1700 may be used by that user 190, so that user 190 may continue to breathe while concurrently having their face 192 (mouth and/or their nose) completely (entirely) submerged within immersion-liquid 180. Note, breathing-apparatus 1700 is further shown in FIG. 17A through FIG 17H and is further discussed in the discussion of those figures.

FIG. 1A also shows handles 1300 of soaking-device 100. In some embodiments, handles 1300 may be configured for user 190 to hold and/or carry soaking-device 100, with or without immersion-liquid 180 within the vessel portion of soaking-device 100. Note, handles 1300 are further shown in FIG. 13A through FIG. 13D and in FIG. 14A through FIG. 14C and is further discussed in the discussion of those figures.

FIG. IB shows the front, top, and right-side perspective view of overall assembled soaking-device 100. Note, FIG. IB largely differs from FIG. 1A, in that in FIG. IB user 190 does not have their face 192 immersed (submerged) within immersion-liquid 180 within the vessel portion of soaking-device 100. Because face 192 of user 190 is not occupying the vessel portion of soaking-device 100 in FIG. IB, more of floor-and-sidewalls 101, front-panel 103, rear-panel 105, and handles 1300 may be seen in FIG. IB as compared to FIG. 1A.

With respect to front-panel 103 and/or rear-panel 105 shown in FIG. IB, in some embodiments, front-panel 103 and/or rear-panel 105 may be a (mostly / substantially) vertically oriented planar member(s) of soaking-device 100. In some embodiments, front-panel 103 and/or rearpanel 105 may be a (mostly I substantially) vertically upright member of soaking-device 100. In some embodiments, front-panel 103 and rear-panel 105 may be disposed oppositely from each other. In some embodiments, front-panel 103 and rear-panel 105 may be separated from each other by a length of floor-and-sidewalls 101. In some embodiments, front-panel 103 and/or rearpanel 105 may comprise two opposing sides (major surfaces), namely, an internal (interior) surface and an external (exterior) surface. In some embodiments, the external (exterior) surfaces of front-panel 103 and/or of rear-panel 105 may face away from each other (and away from soaking-device 100). In some embodiments, the internal (interior) surfaces of front-panel 103 and/or of rear-panel 105 may face each other. In some embodiments, when front-panel 103 and rearpanel 105 may be installed and/or assembled forming aspects of soaking-device 100, then the major planar surfaces (internal and/or external) of front-panel 103 and rear-panel 105 may be substantially parallel with each other. In some embodiments, at least some of the internal (interior) surfaces of front-panel 103 and/or rear-panel 105 may be wetted and/or intended to be wetted by immersion-liquid 180. In some embodiments, at least some of the internal (interior) surfaces of front-panel 103 and/or of rear-panel 105 may be configured to directly physically contact and hold immersion-liquid 180. In some embodiments, the external (exterior) surfaces of front-panel 103 and/or of rear-panel 105 may not be intended to directly hold immersion-liquid 180. In some embodiments, the external (exterior) surfaces of front-panel 103 and/or of rear-panel 105 may not be intended to directly physically touch and/or be wetted by immersion-liquid 180, except for incidental splash or the like.

With respect to rear-panel 105 shown in FIG. IB, in some embodiments, a portion of rear-panel 105, including its internal (interior) surfaces may be at least substantially (mostly) optically see through, transparent, translucent, and/or the like (with respect to average/typical human vision). Whereas, in some embodiments, the external (exterior) surface(s) of rear-panel 105 may be at least substantially (mostly) non-see through, opaque, non-optically transparent, non- optically translucent, and/or the like (with respect to average/typical human vision). In some embodiments, the external (exterior) surface(s) of rear-panel 105 may be covered in a solid backing of at least one color so as to be at least substantially (mostly) non-see through, opaque, non- optically transparent, non-optically translucent, and/or the like (with respect to average/typical human vision). Thus, lighting into a top portion of rear-panel 105 may exit through internal (interior) surfaces of rear-panel 105.

Additionally, FIG. IB shows that a (removable) neck-gasket 500 and a (removable) wedge 600 may be attached to front-panel 103. In some embodiments, neck-gasket 500 and/or wedge 600 may be attached to front-panel 103. In some embodiments, neck-gasket 500 and/or wedge 600 may be removably attached to front-panel 103. In some embodiments, soakingdevice 100 and/or front-panel 103 may comprise neck-gasket 500 and/or wedge 600.

With respect to neck-gasket 500, in some embodiments, when the body portion (or portion thereof) of user 190 may be (removably) immersed within the vessel portion of soakingdevice 100, another (different) body portion (or portion thereof) of user 190 may be in removable and in watertight (waterproof) physical contact with a top portion and/or a side portion of neckgasket 500. For example, and without limiting the scope of the present invention, when a human 190 face may be immersed within immersion-liquid 180 within the vessel of soaking-device 100 (i.e., the face is the body portion), a front of a neck of that person 190 may physically touch and rest up against a waterproof flexible portion of neck-gasket 500 to form a temporary watertight seal between the front of the neck of user 190 and the neck-gasket 500 (i.e., the front of the neck of user 190 may be the other [different] body portion). See e.g., FIG. 5F that shows this front of the neck of user 190 in removable physical interaction with neck-gasket 500. Also note, this this front of the neck of user 190 in removable physical interaction with neck-gasket 500 is occurring in FIG. 1 , but is not readily visible from FIG. 1 . In some embodiments, the waterproof flexible portion of the neck-gasket 500 may be a waterproof elastomeric material like neoprene (or silicone or rubber).

Also shown in FIG. IB are portions of the floor-and-sidewalls 101. See FIG. 11A and in FIG. 11B for just the floor-and-sidewalls 101 component shown by itself. In some embodiments, upper-surface 1109 portions of the floor-and-sidewalls 101 shown in FIG. IB may be wetted with immersion-liquid 180; and in general, immersion-liquid 180 may be (temporary) residing on top of these visible surfaces of the floor-and-sidewalls 101 shown in FIG. IB. In some embodiments, the floor-and-sidewalls 101 member may be a continuous member that serves as both a (wetted or wettable) floor and as opposing (wetted or wettable) sidewalls to the vessel of soaking-device 100. In some embodiments, floor-and-sidewalls 101 member may be waterproof. In some embodiments, floor-and-sidewalls 101 member may be made from a material (or materials) that is considered by persons of ordinary skill in the relevant industries to be good or desira- ble at heat transfer, such as, but not limited to, a metal, an alloy, stainless steel, graphene, and/or the like.

Also shown in FIG. IB is a portion of one of two opposing side-panels 107 (i.e., a portion of the right side-panel 107). In some embodiments, a given side-panel 107 may be a (mostly / substantially) vertically oriented planar member of soaking-device 100. In some embodiments, a given side-panel 107 may be a (mostly / substantially) vertically upright member of soakingdevice 100. In some embodiments, side-panels 107 may not be intended to directly hold immersion-liquid 180. In some embodiments, side-panels 107 may not be intended to directly physically touch and/or be wetted by immersion-liquid 180, except for incidental splash or the like. That is, side-panels 107 may not be direct portions of the vessel portion of soaking-device 100. In some embodiments, side-panels 107 may form exterior opposing side walls of soaking-device 100. In some embodiments, the main (majority) exterior sides and/or surfaces of soaking-device 100 may be defined by exterior portions of front-panel 103, rear-panel 105, and side-panels 107. In some embodiments, the exterior portions of front-panel 103, rear-panel 105, and side-panels 107 may wrap around and/or enclose an entire perimeter of soaking-device 100.

Also shown in FIG. IB are two opposing handles 1300. In some embodiments, these two opposing handles 1300 may have elongate lengths that are at least substantially parallel with each other. In some embodiments, each handle 1300 may be attached to a given side-panel 107 (near the top of the given side-panel 107). In some embodiments, each handle 1300 may be resting on top of a given side-panel 107 and on top of a portion of the floor-and-sidewalls 101 (this portion of the floor-and-sidewalls 101 is a top-ledge 1105 shown in FIG. 11 A and in FIG. 11B).

Also shown in FIG. IB in a slot 1400 visible on one of the handles 1300 (although each handle 1300 may each comprise such a slot 1400). In some embodiments, such a slot 1400 may also be present on the other handle 1300, but not visible in FIG. IB because of the viewing angle. In some embodiments, these slots 1400 of the handles 1300 may run in a parallel direction as the elongate length of the given handle 1300. In some embodiments, a cross-section of a given slot 1400 may be at least substantially (mostly) “T” shaped. In some embodiments, slots 1400 may be opposing each other, with a lengthwise opening to the given slot 1400 facing each other, when each handle 1300 may be installed (assembled) onto its respective side-panel 107. In some embodiments, these slots 1400 may function as a track (rail) system for (removable) attachment of various mating-members 1407. In some embodiments, a given mating- member 1407 may have a portion that is configured to fit into and be captured by a given slot 1400. An example of such a mating-member 1407 is shown in FIG. 14B and in FIG 14C FIG. 1C shows a different front and top perspective view of the overall assembled soaking-device 100 (i.e., different from FIG. 1A and/or from FIG. IB). FIG. 1C shows most of the same components (parts) of soaking-device 100 as FIG.

FIG. 2B a top front perspective of front-panel 103 that shows a neck-gasket-channel 201 within a top 203 of a cutout region 205 of front-panel 103. FIG. 2B shows a more enlarged (closer up view) of neck-gasket-channel 201 as compared to neck-gasket-channel 201 shown in FIG. 2A. Note, FIG. 2A and FIG. 2B shows front-panel 103 with its neck-gasket 500 and its wedge 600 removed from a neck-gasket-channel 201 of front-panel 103. Whereas, in FIG. 1A to FIG. 1G, the neck-gasket 500 and the wedge 600 were shown and/or were removably attached to frontpanel 103. However, when the neck-gasket 500 and the wedge 600 may be removably attached to front-panel 103, then the neck-gasket-channel 201 of front-panel 103 may not be readily visible because neck-gasket-channel 201 may be at least partially visibly blocked by portions of neck-gasket 500 and of wedge 600 being seated within neck-gasket-channel 201.

As shown in FIG. 2A and in FIG. 2B, a top 203 center region of front-panel 103 has cutout region 205. In some embodiments, cutout region 205 may have top portions that are below (beneath) top 203 of front-panel 103. In some embodiments, when cutout region 205 may be view from a front view (or a back [rear] view), cutout region 205 may have a shape that is at least substantially (mostly) similar to one or more of: a half-circle, a semi-circle, a half-oval, a halfellipse, a polygon, a half-polygon, a square, a rectangle, portions thereof, combinations thereof, and/or the like. Note, cutout region 205 need not be formed from cutting into a top 203 of frontpanel 103.

Continuing discussing FIG. 2A and FIG. 2B, in some embodiments, extending into cutout region 205 from its top (a finite and fixed distance), may be a channel, namely, the neckgasket-channel 201. In some embodiments, neck-gasket-channel 201 may be a channel that runs a fixed (finite) distance into a portion of a top cutout region 205 of front-panel 103. In some embodiments, neck-gasket-channel 201 may be configured to (removably) receive the bottom portions of neck-gasket 500 and of wedge 600 to create the watertight (waterproof) seal between the neck-gasket 500 and front-panel 103. In some embodiments, neck-gasket-channel 201 may be configured for removably receiving a bottom portion of the neck-gasket 500. In some embodiments, neck-gasket-channel 201 may be configured for removably receiving a bottom portion of the wedge 600. In some embodiments, neck-gasket-channel 201 may be configured for removably receiving the bottom portion of the neck-gasket 500 and the bottom portion of the wedge 600. In some embodiments, the bottom portion of neck-gasket 500 may be held removably in place within neck-gasket-channel 201 by wedge 600 that also fits into the neck-gasket-channel 201 and presses up against the bottom portion of neck-gasket 500. When the neck-gasket 500 may be removably attached to front-panel 103 in this manner, there may be a continuous watertight (waterproof) seal between portions of front-panel 103 that physically contact neck-gasket 500.

FIG. 3A to FIG. 3C are a series of three sequential drawings showing a sequential process of inserting the bottom edge portions of neck-gasket 500 into its receiving neck-gasket- channel 201. FIG. 3A is a top front perspective view of front-panel 103 and showing a bottom portion of neck-gasket 500 not yet inserted within its receiving neck-gasket-channel 201. FIG. 3A shows a beginning of the process to removably attach neck-gasket 500 to the front-panel 103. In some embodiments, the bottom edge portions of neck-gasket 500 will be inserted into its receiving neck-gasket-channel 201.

FIG. 3B is a top front perspective view of front-panel 103 and showing bottom portions of neck-gasket 500, with some of the bottom portions of neck-gasket 500 being inserted its receiving neck-gasket-channel 201 located in front-panel 103.

However, note at this point shown in FIG. 3C, wedge 600 is not yet also inserted into receiving neck-gasket-channel 201 located in front-panel 103, and thus there may not be a watertight (waterproof) seal between neck-gasket 500 and front-panel 103.

FIG. 4A to FIG. 4C are a series of four sequential drawings showing a sequential process of inserting the bottom edge portions of wedge 600 into neck-gasket-channel 201 (of front-panel 103) and adjacent to the already inserted bottom edges of neck-gasket 500 into neck-gasket- channel 201. Note, FIG. 1A to FIG. 1G, show and/or have both the neck-gasket 500 and the wedge 600 fully and entirely inserted (seated) to neck-gasket-channel 201, resulting in the watertight (waterproof) seal between neck-gasket 500 and front-panel 103.

FIG. 4A is a top front perspective view of front-panel 103, with neck-gasket 500 inserted into its neck-gasket-channel 201 located on front-panel 103, and with wedge 600 not yet inserted into this neck-gasket-channel 201. FIG. 4A shows a beginning of the process to removably attach wedge 600 to the front-panel 103. In some embodiments, wedge 600 may be inserted into neck-gasket-channel 201 next to the already inserted bottom edge portions of neck-gasket 500 such that the inserted wedge 600 will press (wedge) up against the inserted portions of neckgasket 500 within neck-gasket-channel 201. In some embodiments, the insertion process of wedge 600 may be very similar to the insertion process of neck-gasket 500. In some embodiments, wedge 600 may be a stiff/rigid member.

FIG. 4B is a top front perspective view of front-panel 103, with neck-gasket 500 inserted into its receiving neck-gasket-channel 201 located on front-panel 103, and with wedge 600 only partially inserted into this neck-gasket-channel 201. FIG. 4B shows the process to removably attach wedge 600 to front-panel 103 a bit further along as compared to FIG. 4A. Now in FIG. 4B, at least some of the bottom edge portions of wedge 600 have been inserted into neck-gasket- channel 201 next to the already inserted neck-gasket 500.

FIG. 4C is a top front perspective view of front-panel 103, with neck-gasket 500 inserted into its receiving neck-gasket-channel 201 located on front-panel 103, and with wedge 600 more inserted into this neck-gasket-channel 201 as compared to FIG. 4B. FIG. 4C shows the process to removably attach wedge 600 to front-panel 103 further along as compared to FIG. 4B. Now in FIG. 4C, more of bottom edge portions of wedge 600 have been inserted into neck-gasket- channel 201 next to the already inserted neck-gasket 500.

See FIG. IB for when wedge 600 has been fully (entirely) inserted into neck-gasket- channel 201 next to the already inserted neck-gasket 500. Once wedge 600 is fully (entirely) inserted into neck-gasket-channel 201 and neck-gasket 500 has already been fully (entirely) inserted into neck-gasket-channel 201 (e.g., as shown in FIG. IB), then where neck-gasket 500 physically contacts surfaces of neck-gasket-channel 201 may form the watertight (waterproof) seal between neck-gasket 500 and front-panel 103. Once wedge 600 is fully (entirely) inserted (e.g., as shown in FIG. IB), then neck-gasket 500 and front-panel 103 interface may be watertight (waterproof).

Removal of neck-gasket 500 may proceed in essentially the reverse steps, i.e., wedge 600 may be removed first from neck-gasket-channel 201 and then neck-gasket 500 may be removed from neck-gasket-channel 201. In some embodiments, wedge 600 may be removed from neckgasket-channel 201 by squeezing opposing prongs 601 of wedge 600 towards each other and lifting (pulling) wedge 600 away from 201.

FIG. 5A is a top perspective exploded view of the neck-gasket 500 assembly, showing that the neck-gasket 500 may be at least comprised of two separate parts (components), namely, a flexible-member 501 and a rigid-member 503. That is, reference numeral “500” may refer to the overall neck-gasket assembly, in its assembled configuration, that may at least comprise flexiblemember 501 and rigid-member 503. In some embodiments, flexible-member 501 may be a flexible member. In some embodiments, flexible-member 501 may be a waterproof material. In some embodiments, flexible-member 501 may be an elastomeric material. In some embodiments, flexible-member 501 may be selected from one or more of: neoprene, silicone, rubber, a flexible plastic, portions thereof, combinations thereof, and/or the like. In some embodiments, flexible-member 501 may be a flat and planar member that is wider (or longer) than thick. In some embodiments, when flexible-member 501 may be spread out and laying flat upon a flat substrate surface, then flexible-member 501 may have a predetermined shape that at least substantially matches and/or is sized to cover over void space formed from the cutout region 205 of front-panel 103, except that a top of flexible-member 501 may extend above top 203 of frontpanel 103. For example, and without limiting the scope of the present invention, when cutout region 205 may have a substantially semi-circle shape, then flexible-member 501 may also have a substantially semi-circle shape (and/or of a similar size), except for the top of flexible-member 501.

Continuing discussing FIG. 5A, in some embodiments, rigid-member 503 may be planar flat rigid member that has a shape that at least substantially (mostly) complementary matches a bottom edge shape of flexible-member 501, such that when rigid-member 503 is attached to the bottom portions of flexible-member 501, then that neck-gasket 500 assembly shares a common bottom edge shape that is now rigid, whereas, the rest of flexible-member 501 may remain flexible. For example, and without limiting the scope of the present invention, when the bottom edge portions of flexible-member 501 may be have a substantially (mostly) U-shape or a half-arc of a circle shape, then rigid-member 503 may have a similarly sized and shape U-shape or have a shape that is of a similar shape and size to the half-arc of circle shape. In some embodiments, rigid-member 503 may be configured to function as a stiffener that is attached to the bottom side portion of flexible-member 501 to provide some stiffness (rigidity) to the bottom edge portions of neck-gasket 500.

FIG. 5B is a view of flexible-member 501 showing a portion of flexible-member 501 being bent and/or folded over on itself to demonstrate that flexible-member 501 may be flexible. FIG. 5B shows that flexible-member 501 may be flexible.

In some embodiments, neck-gasket 500 may comprise flexible-member 501, rigid- member 503, and adhesive 505. In some embodiments, neck-gasket 500 may comprise flexiblemember 501, rigid-member 503, adhesive 505, and backing 507. In some embodiments, adhesive 505 may be an adhesive. In some embodiments, adhesive 505 may be configured for attach- ing a side of rigid-member 503 to a bottom side portion of flexible-member 501 to form neckgasket 500.

FIG. 5D shows a bottom side edge portion of flexible-member 501 being attached to a side of rigid-member 503 by using of adhesive 505, wherein adhesive 505 is disposed between the bottom side edge portion of flexible-member 501 and the side of rigid-member 503. In FIG. 5D this attachment process is shown as only being partially completed, i.e., in process.

FIG. 5E shows the bottom side edge portion of flexible-member 501 having been fully (entirely) attached to the side of rigid-member 503 by use of adhesive 505, wherein adhesive 505 is disposed between the bottom side edge portion of flexible-member 501 and the side of rigid- member 503. In FIG. 5E this attachment process is shown in its completed state, such that fully assembled neck-gasket 500 is shown in FIG. 5E.

FIG. 5F is a bottom front and (right) side partial perspective view of soaking-device 100, with a focus on showing how neck-gasket 500 removably interacts with a body part of user 190, such as, a front of a neck of user 190. FIG. 5F is a different view of the situation of FIG. 1A, i.e., when user 190 has their face immersed within the vessel portion of soaking-device 100 (e.g., with the face of user 190 within the immersion-liquid 180), and the front of the neck of user 190 is in removable physical contact with side surface(s) of neck-gasket 500. In some embodiments, when the front of the neck of user 190 may be physically pressing up against side surface(s) of neck-gasket 500 and physically touching side surface(s) of neck-gasket 500, then there may be (secondary) watertight (waterproof) seal as between the front of the neck of user 190 and the side surface(s) of neck-gasket 500, wherein this may be deemed a “secondary” watertight (waterproof) seal in comparison to a “primary” watertight seal that may exist between neck-gasket 500 and neck-gasket-channel 201 of front-panel 103. In some embodiments, as soon the neck of user 190 is removed from neck-gasket 500, this secondary watertight seal may cease to exist; however, the immersion-liquid 180 will not leak out from the vessel portion of soaking-device 100 because when the face of the user 190 is removed from this vessel the immersion-liquid 180 level within the vessel naturally lowers a bit and is not sufficiently high to come over a top of neckgasket 500 (nor over the top of this vessel).

FIG. 6 is a perspective view of just wedge 600 shown by itself. In some embodiments, wedge 600 may be a rigid member. In some embodiments, wedge 600 may be made from one or more of: a metal, an alloy, a wood, a composite, a plastic, a reinforced plastic, a laminate, portions thereof, combinations thereof, and/or the like. In some embodiments, wedge 600 may be planar flat rigid member (except for its prongs 601) that has a shape that at least substantially (mostly) complementary matches a bottom edge shape of neck-gasket 500 and/or of neck-gasket- channel 201. For example, and without limiting the scope of the present invention, when the bottom edge portions of neck-gasket 500 may be have a substantially (mostly) U-shape or a half-arc of a circle shape, then wedge 600 (except for its prongs 601) may have a similarly sized and shape U-shape or have a shape that is of a similar shape and size to the half-arc of circle shape. In some embodiments, wedge 600 (except for its prongs 601) may be configured to fit at least mostly into neck-gasket-channel 201 and up against the bottom edge portions of neck-gasket 500 that are already within neck-gasket-channel 201. In some embodiments, wedge 600 (except for its prongs 601) may be shaped and/or sized to fit at least mostly into neck-gasket-channel 201 and up against the bottom edge portions of neck-gasket 500 that are already within neck-gasket- channel 201. In some embodiments, wedge 600 (except for its prongs 601) may be configured to function as a wedge to help push portions of neck-gasket 500 up against surfaces of neck-gasket- channel 201, to form the primary watertight (waterproof) seal.

Continuing discussing FIG. 6, in some embodiments, wedge 600 may have two terminal ends. In some embodiments, wedge 600 may comprise a prong 601 located at each of its terminal ends. In some embodiments, prongs 601 of wedge 600 may point at least substantially (mostly) orthogonally away from the flat planar surfaces of wedge 600. In some embodiments, prongs 601 of wedge 600 may be configured to aid in removal of wedge 600 from neck-gasket-channel 201. In some embodiments, wedge 600 may be removed from neck-gasket-channel 201 by squeezing opposing prongs 601 of wedge 600 towards each other and lifting (pulling) wedge 600 away from 201.

In some embodi- ments, prior to attaching a terminal-end 1107 of floor-and-sidewalls 101 to channel 705 of the internal (interior) surface 701 of front-panel 103, a given end-gasket 1200 may need to be attached to that given terminal-end 1107. See e.g., FIG. 16G which shows a process of attaching a given end-gasket 1200 to a given terminal-end 1107 of floor-and-sidewalls 101. Once, the given endgasket 1200 has been attached to the given terminal-end 1107 of floor-and-sidewalls 101, then that combination of terminal-end 1107, with attached end-gasket 1200, may be fitted into channel 705 of the internal (interior) surface 701 of front-panel 103.

FIG. 16F shows the progress from FIG. 16E of attaching floor-and-sidewalls 101 to front-panel 103. FIG. 16F is a partial top perspective view of the inside of front-panel 103, with floor-and-sidewalls 101 attached to front-panel 103. FIG. 16F shows a given terminal-end 1107 combined with an attached end-gasket 1200 are together fitted into channel 705 of the internal (interior) surface 701 of front-panel 103, forming (creating) a watertight seal between floor-and- sidewalls 101 and front-panel 103. FIG. 16F may show (removable) attachment of one (1) terminal-end 1107 of floor-and-sidewalls 101 to the internal (interior) surface 701 of front-panel 103. In some embodiments, that one (1) terminal-end 1107 of floor-and-sidewalls 101 may be retained (captured) within receiving-channel 1201 of one (1) end-gasket 1200; and then that endgasket 1200 along with its retained terminal-end 1107 of floor-and-sidewalls 101 may together both be fitted into the channel-for-end-gasket 705 that may be located on the internal (interior) surface 701 of front-panel 103; wherein this attachment configuration may result in a watertight seal between the internal (interior) surface 701 of front-panel 103 and floor-and-sidewalls 101. Note, in some embodiments, attaching floor-and-sidewalls 101 to front-panel 103, may be done before or after sliding bottom-panel 113 into three of slots 703 of front-panel 103 and of the sidepanels 107. In terms of the overall assembly of a given soaking-device 100, FIG. 16E and FIG. 16F (i.e., attaching floor-and-sidewalls 101 to front-panel 103) may come before or after FIG. 16D (i.e., sliding bottom-panel 113 into three of slots 703 of front-panel 103 and of the sidepanels 107).

FIG. 16G is rear top partial perspective view, showing how a given terminal-end 1107, of floor-and-sidewalls 101, may be attached to receiving-channel 1201 of a given end-gasket 1200. In some embodiments, FIG. 16G may show end-gasket 1200 being fitted onto one (1) terminalend 1107 of floor-and-sidewalls 101. In some embodiments, in FIG. 16G, the other terminal-end 1107 of floor-and-sidewalls 101, and the other end-gasket 1200, that are not shown in FIG. 16G may have already been attached to front-panel 103 as shown in FIG. 16F. In some embodiments, in FIG. 16G, one (1) end-gasket 1200 may be completely fitted onto one (1) terminal-end 1107 of floor- and- sidewalls 101 before rear-panel 105 may be attached to side-panels 107. In some embodiments, to attach a given end-gasket 1200 to a given terminal-end 1107 of floor-and- sidewalls 101, that terminal-end 1107 may be pushed into the receiving-channel 1201 of that end-gasket 1200.

FIG. 16H shows a close-up detail view of how a given terminal-end 1107, of floor-and- sidewalls 101, that has an attached end-gasket 1200, may together be fitted into channel 719 of the internal (interior) surface 701 of rear-panel 105, to form (create and/or generate) a watertight seal between floor-and-sidewalls 101 and rear-panel 105. In some embodiments, FIG. 16H may show fitting of a given end-gasket 1200 that is retained on a given terminal-end 1107 of floor- and-sidewalls 101 into the channel-for-end-gasket 719 located on the internal (interior) surface 701 of rear-panel 105. Completion of this fitting may result in a watertight seal between at least some of the internal (interior) surface 701 of rear-panel 105 and floor-and-sidewalls 101. Note, this fitting process shown in FIG. 16H between one end of floor-and-sidewalls 101 (along its attached end-gasket 1200) and rear-panel 105, may be essentially the same fitting process between the other end of floor-and-sidewalls 101 (along its attached other end-gasket 1200) and front-panel 103 (see e.g., FIG. 16F). FIG. 16H may also show how bores 1203 of side-panels 107 and of apertures 721 of rear-panel 105 may be colinearly aligned to receive various portions of fasteners 109 for attaching rear-panel 105 to the side-panels 107.

In some embodiments, during intended use, subject 3905 may also use a breathing apparatus (e.g., snorkel or the like), for example, when face 3909 (face 192) may be down and being struck by liquid 3907 (liquid 3603).

Continuing discussing FIG. 36, in some embodiments, catch basin 3605 may function as a catch basin to receive dripping (falling) liquid 3907 (liquid 3603) after such liquid 3907 (liquid 3603) has been sprayed against face 3909 (face 192) and/or against head 3909 (head 191). In some embodiments, catch basin 3605 may be configured to receive and/or hold liquid 3907 (liq- uid 3603) therein. In some embodiments, catch basin 3605 may be at least substantially (mostly) waterproof. In some embodiments, catch basin 3605 may be at least substantially (mostly) open at its top and concave. In some embodiments, catch basin 3605 may be at least substantially (mostly) open at its top, at least substantially (mostly) closed at its sides and bottom. In some embodiments, the sides and/or the bottom of catch basin 3605 may comprise a drain and/or may be plumbed/connected to a drain.

Continuing discussing FIG. 36, in some embodiments, catch basin 3605 may be fitted with a mostly soft and mostly flexible “neck gasket” as that term is used with respect to the Hy- droeffacer device; wherein this may permit subject 3905 to use face/head thermal delivery device

3600 and/or to use catch basin 3605 with face 3909 (face 192) in a down position and with a soft tissue front of a neck 197 of subject 3905 pressing against catch basin 3605 (pressing against the neck gasket) without hurting/harming the soft tissue front of the neck 197 of subject 3905 and without discomfort to subject 3905 (because no hard surfaces/structures are pressing into the soft tissue of the front of the neck of subject 3905 by virtue of catch basin 3605 including a neck gasket). Note, this type of neck gasket does not go around a circumference entirety of the neck of subject 3905, such as a neck gasket in a commercially available prior art dry suit. Rather this type of neck gasket (utilized in devices 100, 3600, and/or 3700) only is pressed up against the soft tissue front of the neck 197 of subject 3905 during intended use when face 3909 (face 192) is in a down position (i.e., face 192 is facing the ground).

Continuing discussing FIG. 36, in some embodiments, at least one jet/nozzle 3601 may be configured to receive temperature-controlled (hot, warm, cold, cool, and/or freezing) liquid 3907 (liquid 3603) and then eject that received temperature controlled (hot, warm, cold, cool, and/or freezing) liquid 3907 (liquid 3603) upwards in the form of temperature-controlled liquid 3907 (liquid 3603) stream/jet. In some embodiments, at least one jet/nozzle 3601 may be attached to catch basin 3605. In some embodiments, at least one jet/nozzle 3601 may ex- tend/protrude upwards from catch basin 3605. In some embodiments, at least one jet/nozzle

3601 may extend/protrude from a concave, sidewall, and/or bottom portion of catch basin 3605. In some embodiments, an inlet/receiving portion of at least one jet/nozzle 3601 may be plumbed (connected) to tubing (such as tubing 3451 and/or 3507), a pump (such as pump 3453), a liquid holding reservoir (such as reservoir 3455), and/or heating and/or cooling means (such as heating and/or cooling means 3407, heating means 4105, cooling means 4107, and/or heating and/or cooling means 4109). In such embodiments, liquid 3907 (liquid 3603) dripping back into catch basin 3605 may then be delivered back to the reservoir via some tubing for continued tempera- ture control and then temperature-controlled liquid 3907 (liquid 3603) may be pumped back from that reservoir to at least one jet/nozzle 3601 via the pump and other tubing. That is, liquid 3907 (liquid 3603) may recirculate in such embodiments to help with the temperature control of liquid 3907 (liquid 3603). Whereas, in other embodiments, at least one jet/nozzle 3601 may be plumbed (connected) to preexisting hot- and cold-water sources of the building where face/head thermal delivery device 3600 may be utilized in/at.

FIG. 37 shows a left side perspective view of a face/head thermal delivery device 3700. In some embodiments, face/head thermal delivery device 3700 may be an example/type of a thermal delivery device 3911 (see e.g., FIG. 39). FIG. 41 may be applicable to face/head thermal delivery device 3700. In some embodiments, face/head thermal delivery device 3700 may comprise at least some electronics of FIG. 41. In some embodiments, face/head thermal delivery device 3700 may fall within category 4209 (see e.g., FIG. 42). In some embodiments, face/head thermal delivery device 3700 may be selected from category 4209. In some embodiments, with respect to face/head thermal delivery device 3700, the heat transfer medium 3907 may be a liquid 3603, such as, but not limited to, water (with or without various predetermined additives). In some embodiments, with respect to face/head thermal delivery device 3700, portion 3909 of subject 3905 (user 190) may be the whole head 191 and/or the face 192 of that subject 3905 or a portion thereof. In some embodiments, face/head thermal delivery device 3700 may comprise: catch basin 3605 and at least one jet/nozzle 3701.

Continuing discussing FIG. 37, in some embodiments, during intended use of face/head thermal delivery device 3700 subject 3905 (user 190) may position their face 3909 (face 192) and/or their head 3909 (head 191) over and proximate (near) catch basin 3605 and below and proximate (near) to at least one jet/nozzle 3701 and temperature-controlled (hot, warm, cold, cool, and/or freezing) liquid 3907 (liquid 3603) may exit at least one jet/nozzle 3701 to spray/stream/drip downwards and against face 3909 (face 192) and/or head 3909 (head 191); wherein then that ejected liquid 3907 (liquid 3603) may then drip (fall) via gravity into basin catch basin 3605. In some embodiments, “over and proximate (near)” between catch basin 3605 and face 3909 (face 192) and/or head 3909 (head 191) may be a distance of two (2) feet or less. In some embodiments, “below and proximate (near)” between at least one jet/nozzle 2403 and face 3909 (face 192) and/or head 3909 (head 191) may be a distance of two (2) feet or less. In some embodiments, during intended use, subject 3905 (user 190) may be sitting, standing, or laying down (with face 3909 [face 192] down or up [with respect to the ground]). In some embodiments, during intended use, subject 3905 may also use a breathing apparatus (e.g., snorkel or the like), for example, when face 3909 (face 192) may be down (pointing down towards the ground) and being struck by liquid 3907 (liquid 3603) in their face 192. In some embodiments, during intended use of face/head thermal delivery device 3700, head 3909 (head 191) (of subject 3905) may be removably disposed between a top / upper portion of catch basin 3605 and below a bottom of the exit/outlet portion(s) of at least one jet/nozzle 3701.

Continuing discussing FIG. 37, in some embodiments, catch basin 3605 may function as a catch basin to receive dripping (falling) liquid 3907 (liquid 3603) after such liquid 3907 (liquid 3603) has been directed against face 3909 (face 192) and/or head 3909 (head 191). In some embodiments, catch basin 3605 may be configured to receive and/or hold at least some of liquid 3907 (liquid 3603) therein. In some embodiments, catch basin 3605 may be at least substantially (mostly) waterproof. In some embodiments, catch basin 3605 may be at least substantially (mostly) open at its top and concave. In some embodiments, catch basin 3605 may be at least substantially (mostly) open at its top, at least substantially (mostly) closed at its sides and bottom. In some embodiments, the sides and/or the bottom of catch basin 3605 may comprise a drain and/or may be plumbed/connected to a drain.

Continuing discussing FIG. 37, in some embodiments, catch basin 3605 may be fitted with a mostly soft and mostly flexible “neck gasket” (where the neck indenture is basin 3605) as that term is used with respect to the Hydroeffacer device; wherein this may permit subject 3905 (user 190) to use face/head thermal delivery device 3700 and/or to use catch basin 3605 with face 3909 (face 192) in a down position (with respect to the ground), with face 3909 (face 192) at least partially inside and/or above a top/upper surface of catch basin 3605 and with the soft tissue front of the neck 197 of subject 3905 pressing against catch basin 3605 (pressing against the neck gasket) without hurting/harming the soft tissue front of the neck 197 of subject 3905 and without discomfort to subject 3905 (because no hard surfaces/structures are pressing into the soft tissue of the front of the neck 197 of subject 3905 by virtue of catch basin 3605 including a neck gasket). Note, this type of neck gasket does not go completely around a circumference entirety of the neck of subject 3905, such as a neck gasket in a preexisting commercially available prior art dry suit. Rather this type of neck gasket (utilized in devices 100, 3600, and/or 3700) only is pressed up against the soft tissue front of the neck 197 of subject 3905 during intended use when face 3909 (face 192) is in a down position (where the down position is pointing / facing towards the ground).

Continuing discussing FIG. 37, in some embodiments, at least one jet/nozzle 3701 may be configured to receive temperature-controlled (hot, warm, cold, cool, and/or freezing) liquid 3907 (liquid 3603) and then eject that received temperature controlled (hot, warm, cold, cool, and/or freezing) liquid 3907 (liquid 3603) down wards (with respect to the ground) in the form of temperature-controlled liquid 3907 (liquid 3603) stream, jet, spray, and/or drips. In some embodiments, at least one jet/nozzle 3701 may be attached to catch basin 3605. In some embodiments, at least some portion of at least one jet/nozzle 3701 may extend/protrude from catch basin 3605. In some embodiments, the exit/outlet portion(s) of at least one jet/nozzle 3701 may be located above catch basin 3605 such that there is a distance gap between a top of catch basin 3605 and a bottom of the exit/outlet portion(s) of at least one jet/nozzle 3701, wherein this distance gap is sized to removably fit head 3909 (head 191) of subject 3905. In some embodiments, this distance gap may be fixed and/or non-variable. In some embodiments, this distance gap may be variable and/or changeable because a height of the exit/outlet portion(s) of at least one jet/nozzle 3701 may be adjustable, variable, and/or changeable. In some embodiments, an inlet/receiving portion of at least one jet/nozzle 3701 may be plumbed (connected) to tubing (such as tubing 3451 and/or 3507), pump (such as pump 3453), liquid holding reservoir (such as reservoir 3455), and/or heating and/or cooling means (such as heating means 4105, cooling means 4107, and/or heating and/or cooling means 4109 - see e.g., FIG. 41). In such embodiments, liquid 3907 (liquid 3603) dripping back into catch basin 3605 may then be delivered by to the liquid holding reservoir (such as reservoir 3455) via some tubing (such as tubing 3451 and/or 3507) for continued temperature control and then temperature-controlled liquid 3907 (liquid 3603) may be pumped back from the liquid holding reservoir (such as reservoir 3455) to at least one jet/nozzle 3701 via the pump (such as pump 3453) and some other tubing (such as tubing 3451 and/or 3507). That is, liquid 3907 (liquid 3603) may recirculate in such embodiments to help with the temperature control of liquid 3907 (liquid 3603).

Whereas, in other embodiments, at least one jet/nozzle 3701 may be plumbed (connected) to preexisting hot and cold liquid (water) sources of the building where face/head thermal delivery device 3700 may be utilized in/at.

Continuing discussing FIG. 37, in some embodiments, next to, adjacent, and/or proximate to catch basin 3605 may be support structure 3703 for person 3905 (user 190). In some embodiments, support structure 3703 for person 3905 may be in the form of a chair, seat, couch, day bed, bed, sofa, settee, divan, combinations thereof, and/or the like. In some embodiments, support structure 3703 for person 3905 may be configured for at least most of subject 3905 to removably rest upon (on top of). In some embodiments, support structure for person 3905 may be configured for supporting at least most of subject 3905. In some embodiments, subject 3905 may sit on, lay on, and/or rest on support structure 3703 for person 3905. In some embodiments, support structure 3703 for person 3905 may be one or more of a: chair, seat, couch, day bed, bed, sofa, settee, divan, combinations thereof, and/or the like.

FIG. 38 (prior art) shows a diagram of the human trigeminal nerve 3800. The overall anatomical structure of the trigeminal nerve is well known and readily shown in many anatomy textbooks and/or the like. The trigeminal nerve or portion thereof may be a target of thermal activation, stimulation, delivery, and/or treatment by one or more of the thermal delivery device(s) 3911 (see e.g., FIG. 39) shown and discussed herein that may be used to thermally target at least the face 192 and/or the head 191 as the portion(s) 3909 (see e.g., FIG. 39). The trigeminal nerve, also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and chewing. The trigeminal nerve is the most complex of the cranial nerves. The trigeminal nerve name ("trigeminal" = tri-, or three, and - geminus, or twin: so "three-born, triplet") derives from each of the two nerves (one on each side of the pons) having three major branches: the ophthalmic nerve (VI), the maxillary nerve (V2), and the mandibular nerve (V3). The ophthalmic and maxillary nerves are purely sensory, whereas the mandibular nerve supplies motor as well as sensory (or "cutaneous") functions. The entire face is made up of the three main peripheral nerves, the three divisions (branches) of the trigeminal nerve (the fifth cranial nerve [CN V] and also the largest and most complex of the twelve [12] cranial nerves) which are the Ophthalmic nerve (VI), the Maxillary nerve (V2), and the Mandibular nerve (V3) all of which converge on the trigeminal ganglion (also called the semilunar ganglion or Gasserian ganglion), located in Meckel's cave and containing the cell bodies of incoming sensory-nerve fibers. Adding to the complexity of the trigeminal nerve is that autonomic nerve fibers as well as special sensory fibers (e.g., taste) are contained within the trigeminal nerve. Note, the trigeminal nerve is wired directly into the brain. Also, note that the trigeminal nerve is without and/or bypasses the blood-brain-barrier (BBB).

FIG. 39 shows a method in a written form, identifying important aspects/parameters of this method via assigned reference numerals. In some embodiments, the invention may be characterized as a method of inducing 3901 a desired and/or intended outcome 3903 in a subject 3905 by touching (placing) a heat transfer element 3907 against (touching) a portion 3909 of the subject 3905, wherein the heat transfer element 3907 may be at least initially at a different temperature from a surface of the portion 3909 of the subject 3905; wherein temperature of the heat transfer element 3907 may be controlled (and/or generated) by a thermal means 3911. In some embodiments, thermal means 3911 may be referred to as a thermal delivery device 3911 and/or as a thermal treatment device 3911.

In some embodiments, the invention may be characterized as a method of inducing 3901 a desired and/or intended outcome 3903 in a subject 3905 by touching (placing) a heat transfer element 3907 against (touching) a portion 3909 of the subject 3905; wherein temperature of the heat transfer element 3907 may be controlled (and/or generated) by the thermal means 3911; wherein the thermal means 3911 provides cold and/or heat to the heat transfer element 3907; wherein at least a portion of that cold and/or heat is transferred from the heat transfer element 3907 to the portion 3909 of the subject 3905, resulting in cooling and/or heating of the portion 3909 of the subject 3905 that results in the desired and/or intended outcome 3903 in the subject 3905.

Note, in a strict thermodynamics sense, when the thermal means 3911 may be making the heat transfer element 3907 cold as compared to the portion 3909 of the subject 3905, heat energy from the portion 3909 of the subject 3905 may be passing into the heat transfer element 3907 and the thermal means 3911 may then be pumping (moving) that heat energy out of the heat transfer element 3907 - because technically heat energy, in the thermodynamic sense, moves from hotter regions to cooler regions; i.e., any cooling process is technically pulling heat out of the object being cooled (and herein the object being cooled is portion 3909).

Continuing discussing FIG. 39, in some embodiments, the “inducing” 3901 word in this method of FIG. 39 may be replaced by: causing, facilitating, generating, producing, triggering, enabling, activating, stimulating, and/or the like.

Similarly, behavioral addictions and/or dependencies, such as, but not limited to, eating, food, sex, gambling, portions thereof, combinations thereof, and/or the like, may be improved by thermal therapies from the method of FIG. 39.

In some embodiments, the increase in neurotransmitter release by the method of FIG. 39, may be mostly with respect to neurons in the brain of the subject 3905 (i.e., the synapses [gaps] between brain neurons), particularly when it may be the facial, cranial, and/or head nerves (of the subject 3905) that may be thermally stimulated by the thermal means 3911 (thermal delivery device 3911).

In some embodiments, the neurotransmitter that the method of FIG. 39 may cause release thereof may be selected from at least one of: dopamine, serotonin, norepinephrine, endorphin, oxytocin, at least one of the four happy hormones, combinations thereof, and/or the like. In some embodiments, dopamine, serotonin, endorphins, and oxytocin may be referred to as the four happy hormones.

In some embodiments, when the desired and/or intended outcome 3903 of this method of FIG. 39 may at least be a release of brain/cranial neurotransmitters, then the thermal means 3911 (thermal delivery device 3911) (such as, but not limited to, a “face soaking device”) may be configured to deliver the thermal therapy (heat and/or cold) to at least the face and/or the head 191 (cranium) of the subject 3905; i.e., the portion 3909 of the subject 3905 in such scenarios may be at least the face 192 and/or the head 191 (cranium) of the subject 3905.

In some embodiments, the injury that may be treated by the method of FIG. 39 may be at least one of: physical trauma to tissue, soft tissue trauma, a hematoma, a cut, a laceration, a tear, a break, a rip, a puncture, a rupture, a scrape, an abrasion, a portion thereof, a combination thereof, and/or the like, with respect to tissue of the subject 3905.

In some embodiments, portion 3909 (of subject 3905) may be at least some portion of the trigeminal nerve and/or at least some tissue that is touching at least some region of the trigeminal nerve. See e.g., FIG. 38 for a schematic diagram of the trigeminal nerve. Note, the trigeminal nerve is wired directly into the brain (as opposed to being wired to the spinal cord like most of the nerves of a human). Also, note that the trigeminal nerve is without and/or bypasses the blood-brain-barrier (BBB). Of the twelve (12) cranial nerves within the human body, only the trigeminal nerve is associated with four (4) different nuclei, wherein from cranial to caudal, these four (4) nuclei are the: mesencephalic, primary sensory, motor, and spinal nuclei. The trigeminal nerve controls cerebral blood flow. Many studies demonstrate successful regulation of cerebral blood flow via trigeminal nerve stimulation, which may provide at least one framework for controlling and/or managing cerebral blood flow to treat, prevent, or mitigate various disorders of cerebral perfusion. Stimulation of the trigeminal nerve clearly has a significant impact on cerebral perfusion in both normal conditions and pathologic states. Thermal delivery device(s) 3911 may be used to stimulate the trigeminal nerve by thermally stimulating the face 192, the head 191, portions thereof, combinations thereof, and/or the like (wherein the face 192, the head 191, portions thereof, combinations thereof, and/or the like may be examples of portions 3909). It has been shown that head-out but body immersion in hot water increases serum BDNF (brain- derived neurotrophic factor) in healthy human males. In some embodiments, when portion 3909 (of subject 3905) may be at least some portion of the trigeminal nerve and/or at least some tissue that is touching at least some region of the trigeminal nerve (e.g., the face 192 and/or the head 191), then thermal treatment of that portion 3909 may be accomplished by thermal delivery device^) 3911. Thermal delivery device(s) 3911 contemplated herein may be used to increase serum BDNF in subject 3905 by thermally treating portion 3909 (such as, but not limited to, the face 192 and/or the head 191) of subject 3905.

Thermal treatments have been shown to increase in adipocyte-derived hormones, neurotrophic factor, neuron-inducing factor, BDNF (brain-derived neurotrophic factor), and/or complete blood count improvements. The thermal effect of water immersion has been shown to causes changes in the concentration of substances in the blood (such as, but not limited to, blood cells, hormones, lipids, and the like). A study reported that warm water immersion played a direct role in preventing diseases by increasing the levels of adipocyte-derived hormones, which have been associated with obesity and inflammatory disorders. Another study reported that water immersion was beneficial in maintaining brain function and homeostasis by increasing the concentration of brain-derived neurotrophic factor, a neuron- inducing factor, and reducing the concentration of cortisol, which is commonly referred to as the stress hormone. Such changes in the concentration of substances in the blood can be explained by the direct effect of disease prevention and treatment. Thermal delivery device(s) 3911 may be used to provide various thermal treatments to portion(s) 3909 to increase in adipocyte-derived hormones, neurotrophic factor, neuron-inducing factor, BDNF, and/or improve complete blood counts.

Cold water immersion of swimmers has shown improved blood characteristics, such as, that blood exposed to the cold-water immersion appearing like the blood of comparably younger people. Thermal delivery device(s) 3911 contemplated herein may be used to improve blood quality (e.g., making the thermally treated blood appear younger) in subject 3905 by thermally treating portion 3909 (such as, but not limited to, the face 192, the head 191, the hands, the body, etc.) of subject 3905. Thus, thermal therapy via thermal delivery device(s) 3911 may be used as a blood anti-aging, longevity increasing, aging slowing down, reversed aging, and/or as a blood renewal treatment.

Similarly, thermal therapy of the face 192 and/or the head 191 (e.g., the trigeminal nerve or portion thereof) via thermal delivery device(s) 3911 may be used to improve CSF (cerebral spinal fluid). Thermal therapy of the face 192 and/or the head 191 (e.g., the trigeminal nerve or portion thereof) via thermal delivery device(s) 3911 may facilitate CSF having the appearance, qualities, and/or properties of CSF associated with comparably younger people. Thus, thermal therapy via thermal delivery device(s) 3911 may be used as a CSF anti-aging treatment, a CSF that ages more slowly, a CSF with increased longevity, and/or the like. Transplants of younger CSF into older individuals has been associated with improved memory in those older individuals. CSF may be about 80% derived from the blood (while the remaining about 20% consists of brain-derived and intrathecally produced molecules). Further, CSF may be renewed I newly produced three (3) to five (5) per pay. Thus, because CSF may be mainly mostly derived from blood and because thermal treatment of blood may result in that thermally treated blood appearing younger, then thermal treatment of the face 192 and/or the head 191 may also result in CSF that appears younger. Further, note that the flow of CSF through perivascular spaces (PVSs) in the brain is important for clearance of metabolic wastes. Further still, this CSF flow to clear metabolic wastes (e.g., pulsatile) may be controlled, triggered, and/or promoted via cold or hot water immersion. Thus, thermal treatment of the face 192 and/or the head 191 (e.g., as portion(s) 3909) via thermal delivery device(s) 3911 may result in the control, triggering, and/or promotion of clearance of metabolic wastes from the brain, by triggering CSF flow through the PVSs of the brain. Similarly, thermal delivery device(s) 3911 may be used to cool and/or heat portion(s) 3909 to achieve arterial pulsations. For example, cold water immersion may result in arterial blood flow constrictions; whereas, warm/hot water immersion may result in increased arterial blood flow. In some embodiments, an arterial pulsation may be: an intermittent increase in arterial blood flow of a given portion 3909 above a baseline/default value of arterial blood flow; an intermittent decrease and/or constriction in arterial blood flow of a given portion 3909 below a baseline/default value of arterial blood flow; and/or an intermittent increase followed by an intermittent de- crease/constriction in arterial blood flow of a given portion 3909 or vice-versa.

The central nervous system (CNS) and the brain are protected against harmful/foreign substances within the blood by the blood-brain barrier (BBB) and the blood-cerebrospinal (B- CSF) barrier. Such barriers along with liver metabolism of substances in the blood can make delivery of drugs, medications, and/or chemicals to the brain difficult.

The human body often uses various naturally occurring negative feedback loops to reduce the amounts and/or concentrations of compounds (such as, but not limited to, neurotransmitters, hormones, proteins, and/or the like) in the body with a general goal of maintaining homeostasis of the body. In general, a spike of a given compound above a certain threshold will often trigger a negative feedback loop to bring that spiked compound below a threshold. The endocrine system is notorious for such negative feedback loops, with many examples of paired hormones that have opposite effects. However, very often when western medicine is treating a disease and/or health problem, often some compound is made bioavailable to the body, but the long-term efficacy of such delivered compounds is often limited by the bodies’ natural feedback loops which seek to bring the added compound into what the body perceives as a normal amount / concentration. Such naturally occurring negative feedback loops in the human body may make many antiaging, longevity, and/or slowing down the aging process difficult to implement. For example, administering human growth hormones to adults for anti-aging, longevity, and/or slowing down the aging process may have poor long-term efficacy because of the bodies’ natural negative feedback loops which may seek to reduce the amounts/concentrations of such delivered human growth hormones. Successful long-term anti-aging, longevity, and/or slowing down the aging process treatments and/or modalities may need to avoid (not suppress) such natural negative feedback loops. Suppressing the bodies’ natural negative feedback loops might not be desirable, as such suppression may lead to a loss of homeostasis. Thermal treatments using thermal delivery device(s) 3911 may avoid triggering such natural negative feedback loops and result in net increases of desired compounds (such as, but not limited to, neurotransmitters, hormones, proteins, and/or the like) and/or of new neuron growth/development. Note, something like exercise may be inferior to thermal treatments using thermal delivery device(s) 3911. For example, while exercise may cause an intermittent increase in dopamine, such exercised induced dopamine is essentially metabolized as produced and/or requires a significant caloric energy source to fuel the exercise, such that when the energy consumed is considered along with how much and how fast that dopamine is produced and consumed, there is no net gain from the exercise with respect to dopamine production. Whereas, in contrast thermal therapy via a thermal delivery device 3911 may cause net increases in dopamine without caloric energy intake. Thermal treatments using thermal delivery device(s) 3911 may instead trigger the bodies’ natural positive feedback loops, leading to net increases in desired compounds, wherein such increase in desired compounds may be used in various anti-aging, longevity promoting, and/or slowing down the aging process treatments.

In some embodiments, the face 192 (e.g., as portion 3909), because of the trigeminal nerve, may be an ideal, a desired, and/or a better location on the body of subject 3905 for trans- dermal drug delivery. Because the trigeminal nerve is without and/or bypasses the blood-brain barrier, drug transdermal delivery via the face 192 may provide an ideal, a desired, and/or a better location on the body of subject 3905 for getting the administered drug(s) into the brain, to brain cells, and/or into brain cells. Drugs, chemicals, medications, and/or the like (drugs) may bypass the blood-brain barrier because the trigeminal ganglion is outside the blood-brain barrier. In this capacity, the trigeminal ganglion may act as an integrative organ. The trigeminal ganglion thus may be a target of drug action outside the blood-brain barrier.

Because the trigeminal nerve is without the blood-brain barrier, the trigeminal nerve may also be without the blood-cerebrospinal fluid barrier and/or without the blood nerve (or neurol) barrier. If so, the face 192 (e.g., as portion 3909), because of the trigeminal nerve, may further be an ideal, a desired, and/or a better location on the body of subject 3905 for transdermal drug delivery. Any of the thermal delivery devices 3911 shown and discussed herein may be used to heat and/or to cool a given (targeted) region of skin 3909 on a target organism 3905 (e.g., human); wherein application of heat and/or cold to that given (targeted) region of skin 3909, increases the skin’s permeability with respect to one or more chemical species.

Any of the thermal delivery devices 3911 shown and discussed herein may be used for transdermal delivery of one or more chemical species by using the given thermal delivery device 3911 to change and increase the skin’ s 3909 permeability to such chemical species by the application of heat and/or cold to the given (targeted) region of skin 3909; and by having the given chemicals species be in direct physical contact with that given (targeted) region of skin 3909 that has been heat and/or cold treated by the given thermal delivery device 3911. Any of the thermal delivery devices 3911 shown and discussed herein may be used for the delivery of one or more chemical species across a given (targeted) region of skin 3909 and into the target organism’s 3905 body by using the given thermal delivery device 3911 to change and increase the skin’ s 3909 permeability to such chemical species by the application of heat and/or cold to the given (targeted) region of skin 3909; and by having the given chemicals species be in direct physical contact with that given (targeted) region of skin 3909 that has been heat and/or cold treated by the given thermal delivery device 3911.

In some embodiments, a given thermal delivery device 3911 that is heating (and/or cooling) the face 192, may be used for transdermal delivery of (at least partially or mostly) water- soluble chemical species, through the skin of the face 192, and directly into the bloodstream and/or brain (bypassing the blood-brain-barrier [BBB]). For example, at skin and/or body temperature^) of subject 3905 that may be warm enough to induce sweating, hair follicles and/or sweat glands open up thereby allowing more water than normal to penetrate into and/or through the epidermis, which is not typical if the skin/body is not heated up first. The epidermis generally functions to keep external water outside of the body (e.g.. when the body is not sweating). This is at least one reason why some prior art transdermal delivery patches use nonpolar (hydro- phobic) medication(s), as the given nonpolar (hydrophobic) medication may be able pass through the epidermis. However, if the epidermis were thermally treated with a given thermal delivery device 3911, then some water-soluble chemical species may be transdermally delivered through the epidermis of the face 192, and directly into the bloodstream and/or brain (bypassing the blood-brain-barrier [BBB]). For example, and without limiting the scope of the present invention, in this manner, (at least mostly to partially) water-soluble moisturizer(s) may be delivered into the epidermis once the skin has been thermally treated via a given thermal delivery device 3911. This may provide a more effective means of treating/reducing skin wrinkles in the treated region as compared to skin that was not so thermally treated. The thermal treatment of the skin allows deeper penetration into the epidermis of the (at least mostly to partially) water-soluble moisturizer(s) as compared to not using such thermal treatment of the skin. This deeper penetration allows more of the epidermis to benefit from the greater availability of the (at least mostly to partially) water-soluble moisturizer(s).

In some embodiments, the one or more chemical species (chemical-additive and/or at least one chemical) may be predetermined. In some embodiments, the one or more chemical species may be selected from at least one predetermined: chemical, salt, ion, molecule, medicine, medicament, pharmaceutical, biological, carbohydrate, amino acid, peptide, protein, nucleic acid, DNA (e.g., a string of deoxyribonucleic acid), RNA (e.g., a string of ribonucleic acid), fatty acid, hormone, antibiotic, a moisturizer, a skin bleacher, an oxidizer, a skin peal, a skin mud, a skin clay, liposome, portions thereof, combinations thereof, and/or the like. In some embodiments, the one or more chemical species may be at least one of: naturally occurring, synthetic, human made, water soluble, fat soluble, plant derived, algae derived, animal derived, bacteria derived, fungus derived, archaebacteria derived, protozoan derived, portions thereof, combinations thereof, and/or the like.

In some embodiments, the one or more chemical species may be dispersed, carried, and/or dissolved within one or more solvents, carrier fluids, and/or immersion liquids, such as, but not limited to, water.

For example, and without limiting the scope of the present invention, soaking-device 100, whole head thermal delivery device 3500, the Hydroeffacer face soaking device (see e.g., U.S. utility patent 10667990) or any other immersion based thermal delivery device 3911 shown and discussed herein may have its given immersion liquid (e.g., immersion-liquid 180) holding (receiving) vessel appropriately filled with the desired immersion liquid (e.g., water) and the one or more chemical species (additives) may added to that immersion liquid, such that when the given body part 3909 (such as, but not limited to, the face 192, head 191, hand, and/or the like) is immersed within that immersion liquid, with the one or more chemical species (additives), and heat and/or cold is then applied to that immersion liquid from that immersion based thermal delivery device 3911, that applied heat and/or cold, via the immersion liquid, will heat and/or cool the skin of the immersed body part 3909, increasing the skin’s permeability for transdermal delivery of the one or more chemical species. Further, when immersed body part 3909 may be the face 192, the head 191, or portions thereof, and because the trigeminal nerve is without and/or bypasses the blood-brain-barrier (BBB), then the transdermally delivered one or more chemical species (additives) may be further delivered to the brain, brain cells, and/or to CSF (cerebral spinal fluid) of that subject 3909 (user 190). That is, thermal delivery devices 3911 that heat and/or cool the face 192, the head 191, or portions thereof (such as, but not limited to, soaking-device 100, whole head thermal delivery device 3500, the Hydroeffacer face soaking device [see e.g., U.S. utility patent 10667990]), may be used for transdermal delivery of the one or more chemical species (additives) to the brain, brain cells, and/or to CSF of that subject 3909 (user 190).

Note, thermal stimulation and/or activation of the nerves (such as, but not limited to facial and/or cranial nerves) may be more desirable as compared to electrical and/or magnetic stimulation and/or activation of the such nerves. This may be because by virtue of evolution (natural selection), the body has more and/or stronger preexisting pathways that respond to thermal stimulation and/or activation of the nerves since changes in environmental temperatures are common in the environment for organisms to deal with; whereas, electrical and/or magnetic changes are far less common in the environment, so from an evolutionary perspective, most organisms are less likely to have many and/or strong pathways for dealing with electrical and/or magnetic changes. In other words, thermal changes are more normal for a body to deal with as compared to electrical and/or magnetic changes which are more abnormal/unnatural for the body to deal with. As such, it is not unusual that electrical and/or magnetic stimulation and/or activation of the vagus and trigeminal nerves have had limited success.

For instance, electrical and/or magnetic stimulation and/or activation of the vagus nerve stimulates the GABA transmitter/receptor pathway, which once triggered, often inhibits dopamine release that can cause depression, weight gain, and/or addiction; whereas, thermal stimulation and/or activation of the nerves (such as, but not limited to facial and/or cranial nerves) (which is comparatively more normal than electrical and/or magnetic stimulation) may instead increase, promote, and/or generate dopamine release, along with the benefits that may come from a dopamine release.

Because the trigeminal ganglion direct wired connection to the brain (unlike most the other human nerves); because the trigeminal nerve is the largest and most complex cranial nerve; because the trigeminal nerve is outside (without) the blood-brain barrier; because the trigeminal nerve is bathed in CSF; and/or, because the trigeminal nerve is largely located inside the head 191 and gives rise to three main peripheral nerves providing nearly all intra- and extracranial structures with nerve fibers of various somatosensory functions - that the trigeminal nerve largely functions and/or operates as the “motherboard” for the entire body and, therefore, the transition site for sensory information from the periphery to the central nervous system and that intracellular modulatory mechanisms and intercellular signaling are capable of controlling sensory information relevant for the pathophysiology of syndrome, diseases and injury. And hence, thermal stimulation and/or activation of the trigeminal nerve (e.g., via use of thermal delivery de- vice(s) 3911) may be used to treat a variety of syndromes, diseases, and/or injuries.

The blood-brain barrier (BBB) and the blood-cerebrospinal (B-CSF) barrier are main protections to the brain and central nervous system (CNS). But these protections can also be roadblocks to treatments and/or prevention by making it difficult to target and/or reach the brain. Thus, if one can induce and/or cause the body to make its own neurons, hormones, and/or neurotransmitters, via a more natural means, such as, by thermal stimulation and/or activation, which the body has preexisting pathways to utilize, then such thermal stimulation and/or activation of targeted regions, such as, but not limited to the face 192 and/or the head 191, with or without medicine(s), may increase neuron growth and development in a controlled manner and/or release hormones/neurotransmitters to treat, cure, and/or prevent disease; and without triggering the body’s natural defense mechanisms.

Neurogenesis is the process by which new neurons are formed in the brain. Neurogenesis is crucial when an embryo is developing, but also continues in certain brain regions after birth and throughout a human’s lifespan. It has been shown that immersion in thermally controlled water generates positive effects on cerebral blood flows, cortical activation, executive functions, and the production of neurotrophins in healthy subjects. Although the vast majority of neurons in the mammalian brain are formed prenatally, parts of the adult brain (for example, the hippocampus) retain the ability to grow new neurons from neural stem cells, a process known as neurogenesis. Neurotrophins are chemicals that help to stimulate and control neurogenesis. Thermal treatment of portion 3909 (such as, but not limited to, the face 192 and/or the head 191) with thermal delivery device(s) 3911 may result in neurogenesis and in the production of neurotrophins.

Continuing discussing FIG. 39, in some embodiments, the heat transfer element 3907 (or heat transfer medium 3907 or heat transfer fluid 3907) of this method of FIG. 39 may be selected from at least one: a fluid, a liquid, an immersion liquid (immersion-liquid 180), (sprayed / jetted) heat-transfer-liquid 3603, a slurry, a gas, air, cardon dioxide (gas), nitrogen (gas), a gel, a slime, a mud, a paste, a thermal paste, a clay, a metal, an alloy, a solid, beads, sand, a fluidized bed, heat exchanger fluid, refrigeration fluid, water, ice, water ice, dry ice (carbon dioxide ice), ice cubes, crushed ice, ice liquid mixtures, ice water mixtures, mineral water (e.g., for balneotherapy), sparkling water, salt water, acidic water (pH less than 7), soft water, hard water, basic water (in terms pH, i.e., pH higher than 7), oil, air, oxygen, nitrogen, carbon dioxide, antifreeze, ethylene glycol, portions thereof, combinations thereof, and/or the like. In some embodiments, the heat transfer element/medium 3907 may be configured to (adapted to) facilitate a heat transfer means between the portion 3909 (of subject 3905 1 user 190) and the thermal means 3911. In some embodiments, the heat transfer means may be selected from at least one: conduction, convection, radiation, portions thereof, combinations thereof, and/or the like. For example, when at least a portion of the heat transfer element/medium 3907 may be a fluid, then heat transfer may predominantly occur by convection and/or by conduction; whereas, when at least a portion of the heat transfer element/medium 3907 may be a solid material (e.g., a metal or alloy), then heat transfer may predominantly occur by conduction (and/or radiation). For example, when at least a portion of the heat transfer element/medium 3907 may be air and/or a gas, then heat transfer may occur by convection, conduction, and/or radiation.

Continuing discussing FIG. 39, in some embodiments, the thermal means 3911 of this method of FIG. 39 may comprise at least one thermostat. In some embodiments, the thermal means 3911 of this method of FIG. 39 may be at least one thermal delivery device 3911.

Tn some embodiments, in addition to or in the alternative to using the thermal delivery device 3911 to generate the desired and/or intended outcome 3903, the thermal delivery device 3911 may also be used recreationally and/or used casually.

In some embodiments, the “face soaking device” may be a device/apparatus/machine at least as substantially (mostly) shown and/or described in U.S. utility patent 10667990, U.S. utility patent 10449341, U.S. utility patent 10667991, U.S. utility patent 391154697, U.S. design patent D863575, U.S. design patent D863576, U.S. design patent D864403, U.S. design patent D889675, and/or U.S. design patent D916303; wherein the “face soaking device” may comprise a vessel (configured to hold an immersion liquid), a breathing apparatus, a headrest, a neck gasket, and at least one heating and/or cooling means. In some embodiments, the immersion liquid (e.g., immersion-liquid 180) may be an example of the heat transfer element/medium 3907 of the method of FIG. 39. In some embodiments, the face soaking device may comprise a means for releasing gas bubbles and/or emitting light into the immersion liquid. In some embodiments, the gas bubbles may be from air, oxygen, nitrogen, carbon dioxide, other predetermined gas, portions thereof, combinations thereof, and/or the like.

In some embodiments, the face soaking device may be referred to as a “Hydroeffacer.”

Note, prior art thermal therapies (such as body cold water immersion) generally involve the patient being in a standing position and not in a position where the body is entirely at rest and supported. Whereas, with the face soaking device (Hydroeffacer) the entire body may be at rest and supported during the thermal therapy; e.g., the body may be sitting down and the head 191 is entirely supported by the headrest of the face soaking device (Hydroeffacer); wherein thermal therapies administered by the face soaking device (Hydroeffacer) may result in greater amounts of neurotransmitters as compared to merely standing (or swimming) cold water body immersion. Note, when the “face soaking device” may be used to treat and/or improve a region of skin and/or tissues there below (such as, but not limited to, the face 192 or portion thereof) then the “face soaking device” may be referred to as a skin treatment device.

In some embodiments, the inverted dry suit (e.g., of a thermal delivery device 3911), from U.S. provisional patent application 63/390,926 filed on July 20, 2022, may have circumferential gaskets for the ankles, wrists, and/or neck of subject 3905 (user 190) (i.e., where the given gasket goes entirely around the entire perimeter circumference of the given ankle, wrist, and/or neck of subject 3905 [user 190]). In some embodiments, the inverted dry suit, from U.S. provisional patent application 63/390,926 filed on July 20, 2022, may be configured to retain an immersion liquid within the inverted dry suit, but to otherwise be dry on an exterior of the inverted dry suit. In some embodiments, the immersion liquid may be an example of the heat transfer el- ement/medium 3907 of the method of FIG. 39.

In some embodiments, a transdermal patch (e.g., of a thermal delivery device 3911) that does have its own heating and/or cooling capability may be used in conjunction with a given thermal delivery device 3911. For example, and without limiting the scope of the present invention, a given transdermal patch, without its own heating and/or cooling capability, may be worn on the face 192 before, during, and/or after thermal treatment via use of a given thermal delivery device 3911. For example, and without limiting the scope of the present invention, a given transdermal patch, without its own heating and/or cooling capability, may be worn on the face 192 before, during, and/or after thermal treatment via use of a given soaking-device 100, whole head thermal delivery device 3500, the “face soaking device” (Hydroeffacer), or the like. In some embodiments, the thermal delivery device 3911 may comprise at least a portion of the heat transfer element/medium 3907. In some embodiments, the thermal delivery device 3911 may contain, house, retain, and/or the like at least a portion of the heat transfer element/medium 3907 within some portion of the thermal delivery device 3911.

In some embodiments, the thermal delivery device 3911 may comprise at least one heating and/or cooling means (see e.g., heating means 4105, cooling means 4107, and/or heating and/or cooling means 4109 of FIG. 41). In some embodiments, at least one heating and/or cooling means may be operationally attached to the thermal delivery device 3911. In some embodiments, the at least one heating and/or cooling means may be located externally, internally, or a combination of both external and internal with respect to the thermal delivery device 3911. In some embodiments, a given thermal delivery device 3911 may be configured to provide cooling, heating, heating and cooling at the same time, heating and cooling at different times, only/just cooling, only/just heating, portions thereof, combinations thereof, and/or the like via the heating and/or cooling means. Note, the at least one heating and/or cooling means may be associated with reference numerals 4105, 4107, and/or 4109. Specifically, 4109 may be a heating and/or a cooling means; 4107 may be just a cooling means; and 4105 may be just a heating means. See FIG. 41 and its discussion for cooling means 4109, cooling means 4107, and/or heating means 4105.

Note, in some applications/uses, cooling therapies may be preferred over heating therapies as overeating may be more dangerous than cooling. For example, heat stroke may be fatal quicker than hypothermia; and heat stroke may be more difficult to treat than hypothermia. Given a same amount of time, excessive heat may be more damaging than excessive cold. Note, depending upon the nature and/or type of the heat transfer element/medium/fluid 3907, different temperatures may be used (e.g., temperatures output by the thermal delivery device 3911). For example, the most extreme (hottest or coldest) temperatures may be used when the heat transfer fluid 3907 may be a gas like air; whereas, comparatively less extreme temperatures may be used when the heat transfer fluid 3907 may be a liquid; and even less extreme temperatures may be used when the heat transfer element/medium 3907 may be a metal/alloy solid. This may be so because rates of heat transfer may be driven at least in part by the nature and/or type of the heat transfer element/medium 3907 utilized. For example, and without limiting the scope of the present invention, if the heat transfer fluid 3907 is humid air, then hot temperatures at or above 120 degrees Fahrenheit (°F) (48.9 degrees Celsius [°C]) (but below 215 °F [101.7 °C]) may be utilized; whereas, if the heat transfer fluid 3907 is water, then hot temperatures from 104 °F (40 °C) to 119 °F (48.3°C) may be used.

In some embodiments, the at least one heating and/or cooling means 4105, 4107, and 4109 may utilize at least one of the following means for heating and/or for cooling the at least the portion of the heat transfer element/medium 3907: a heater using electrical resistance; a heater using inductance; a resistive heater; inductive heating; an emitter of electromagnetic (EM) radiation; an transducer of EM radiation; an electrode; a radiation source; a light source; a heat pump; an ultrasound source; a vibration source; a condenser; a compressor; a refrigerator; a chiller; a freezer; a Peltier circuit; a solid state heating/cooling circuit; a blower; a fan; a radiator; a heat sink; a cooling tower; a pump; a heating and/or a cooling coil; a heat exchanger; a predetermined chemical reaction configured for heating or for cooling; a heat pack; a heated heat pack (e.g., heated via a microwave and/or an oven); a cold pack; a frozen cold pack; a chemical based heat pack; a chemical based cold pack; an ice pack; (water) ice; dry ice; carbon dioxide ice; cold water; cold liquid; cool water; cool liquid; hot water; hot liquid; warm water; warm liquid; hot air; warm air; cold air; cool air; dry air; humid air; liquid nitrogen; portions thereof; combinations thereof; and/or the like.

In some embodiments, this heat transfer gas/fluid (e.g., refrigerant) may be an example of the heat transfer element/medium 3907. In some embodiments, the thermostat may be configured to control heating and/or cooling output of the heating and/or cooling means. In some embodiments, the thermostat may comprise one or more temperature measuring means, such as, but not limited to, thermocouples, temperature probes, thermometers, temperature sensor(s), portions thereof, combinations thereof, and/or the like. In some embodiments, the thermostat may comprise a temperature controller, a PID controller, a PLC controller, portions thereof, combinations thereof, and/or the like. In some embodiments, the thermostat may be configured to obtain a temperature of: at least some portion of the surface of the portion of the subject 3905; at least some portion of the heat transfer ele- ment/medium 3907 (e.g., immersion- liquid 180); at least some portion of the heating and/or cooling means; a portion thereof; a combination thereof; and/or the like.

In some embodiments, the thermal delivery device 3911 may comprise at least one of: the heating and/or cooling means (4105, 4107, and/or 4109); the thermostat; electronics; circuitry; a printed circuit board (PCB); a processor 4101; memory 4103a (transitory memory) e.g., RAM [random access memory]); storage 4103b (non-transitory memory) (e.g., a hard drive [solid state, optical, and/or spinning], backup drive, tape drive, or the like); a means to electrically power electronics of the thermal delivery device 3911 (e.g., Power-Source 4117a); a battery; a means to receive external electrical power (e.g., an electrical plug or an electrical receptacle [e.g., a means for interacting with Power-Source 4117b]); electrical wiring/cabling; firmware; software; inputs means 4113; output means 4113; a portion thereof; a combination thereof; and/or the like. See e.g., FIG. 41. In some embodiments, the thermal delivery device 3911 may be battery powered and/or plugged into an external electrical power source 4117b. In some embodiments, a battery of the thermal delivery device 3911 may be rechargeable (at least for a set quantity of duty cycles).

See e.g., FIG. 41. FIG. 40 is a flowchart of at least some steps of method 4000. In some embodiments, method 4000 may a method of inducing 3901 a desired and/or intended outcome 3903 in a subject 3905 (user 190) by touching (placing) a heat transfer element 3907 against (touching) a portion 3909 of the subject 3905, wherein the heat transfer element 3907 may be at least initially at a different temperature from a surface of the portion 3909 of the subject 3905; wherein temperature of the heat transfer element 3907 may be controlled (and/or generated) by a thermal means 3911. In some embodiments, method 4000 may comprise at least one of the following steps: step 4001, step 4003, step 4005, step 4007, portions thereof, combinations thereof, and/or the like. In some embodiments, at least one of the following steps: step 4001, step 4003, step 4005, step 4007, may be executed sequentially within numeral order. In some embodiments, at least one of the following steps: step 4001, step 4003, step 4005, step 4007, may be executed out of numeral order. In some embodiments, at least one of the following steps: step 4001, step 4003, step 4005, step 4007, may be executed at least partially concurrently (simultaneously). In some embodiments, at least one of the following steps: step 4001, step 4003, step 4005, step 4007, may be optional. Continuing discussing FIG. 40, in some embodiments, step 4001 may be a step of making sure the portion 3909 of the subject 3905 and at least some of the heat transfer element/medium 3907 are in physical contact with each other (or close enough to each other to enable/facilitate heat transfer between each other). In some embodiments, when heat transfer element/medium 3907 may be the immersion liquid of a “face soaking device,” then step 4001 may be executed by making the vessel of the “face soaking device” is at least minimally filled with the immersion liquid and then immersing the user’s (subject 3905) face (portion 3909) into that immersion liquid. In some embodiments, method 4000 may begin with step 4001 (and/or with step 4003). In some embodiments, step 4001 and step 4003 may occur independently, concurrently, sequentially, and/or at least partially overlapping with each other. In some embodiments, step 4001 may progress to step 4003 and/or to step 4005.

Continuing discussing FIG. 40, in some embodiments, step 4003 may be a step of activating the thermal deliver device 3911 such that a temperature of the at least some of the heat transfer element/medium 3907 is within a predetermined temperature range. In some embodiments, step 4003 for the “face soaking device” as the thermal delivery device 3911, may entail turning on the “face soaking device” and setting and/or selecting an operating temperature for the immersion liquid to be within the predetermined temperature range. Note in some embodiments, if the operating temperature is at, or targeted to be at, an endpoint of the predetermined temperature range, that may be considered as the (operating) temperature to be within predetermined temperature range. For example, and without limiting the scope of the present invention, if the predetermined temperature range is 58 °F to 55 °F (14.4 °C to 12.8 °C), then a temperature of 58 °F (14.4 °C) may be considered to be within this predetermined temperature range. In some embodiments, method 4000 may begin with step 4003 (and/or with step 4001). In some embodiments, step 4003 and step 4001 may occur independently, concurrently, sequentially, and/or at least partially overlapping with each other. In some embodiments, step 4003 may progress to step 4001 and/or to step 4005.

Continuing discussing FIG. 40, in some embodiments, step 4005 may be a step of thermally exposing the portion 3909 of the subject 3905 to the predetermined temperature range or a temperature selected from the predetermined temperature range. In some embodiments, step 4005 may continue for a predetermined duration (amount of time) at the temperature from the predetermined temperature range; and that predetermined duration may be dependent upon the temperature of the heat transfer element/medium 3907 (e.g., temperature of the immersion liquid), what region is the portion 3909 (e.g., the face), the type of organism for subject 3905 (e.g., a human), and what specific/particular desired and/or intended outcome 3903 (e.g., dopamine release in the brain) that may be targeted with this particular application of method 4000. In some embodiments, the colder the operating temperature of the heat transfer element/medium 3907 (selected from a given predetermined temperature range) the shorter the duration of thermal exposure of the portion 3909 of subject 3905 may be.

In some embodiments, the hotter the operating temperature of the heat transfer element/medium 3907 (selected from a given predetermined temperature range) the shorter the duration of thermal exposure of the portion 3909 of subject 3905 may be.

For example, and without limiting the scope of the present invention, with respect to adult humans, exposure of 150 °F water for two seconds or exposure of 140 °F water for six second or exposure of 130 °F water for thirty seconds or exposure of 120 °F for five minutes - may cause third degree burns; and this of course may vary by skin thickness, subcutaneous fat thickness, extent of subcutaneous vascularization, and heart rate. Higher subcutaneous vascularization and/or higher heart rates may help to facilitate faster dissipation of thermal energy (because blood is mostly water and water has good heat capacity).

In some embodiments, the operating temperature (of the heat transfer element/medium 3907) and the duration of such thermal exposure may be set and/or controlled such as to avoid harm, damage, burns, hypothermia, heat stroke, heat exhaustion, and/or the like to the subject 3905. In some embodiments, step 4005 may progress to step 4007. Continuing discussing FIG. 40, in some embodiments, step 4007 may be a step of ceasing (stopping) method 4000 if the step 4005 duration runs long enough; the temperature of the heat transfer element/medium 3907 falls outside of the predetermined temperature range; the (surface) temperature of the portion 3909 of the subject 3905 is excessive for too long a period of time.

FIG. 41 may be a block diagram of a given thermal delivery device 3911 showing at least some elements of the given thermal delivery device 3911. In some embodiments, a given thermal delivery device 3911 may be configured to provide: heating and/or cooling to portion 3909: only cooling to portion 3909; only heating to portion 3909; portions thereof; combinations thereof; and/or the like. In some embodiments, at a minimum, a given thermal delivery device 3911 may comprise at least one of heating and/or cooling means 4109, cooling means 4107, and/or heating means 4105, and a skin/body portion contact means 4111.

Continuing discussing FIG. 41, in some embodiments, depending upon the nature of the given thermal delivery device 3911 and its associated heat transfer member(s), medium(s), and/or element(s) 3907, then that thermal delivery device 3911 may also comprise the associated heat transfer member(s), medium(s), and/or element(s) 3907. In some embodiments, when the associated heat transfer member(s), medium(s), and/or element(s) 3907 may be a solid, a gel, beads, portions thereof, combinations thereof, and/or the like, then the associated heat transfer members), medium(s), and/or element(s) 3907 may a part of the given thermal delivery device 3911; and as such, then that given thermal delivery device 3911 may comprise that associated heat transfer member(s), medium(s), and/or element(s) 3907. For example, and without limiting the scope of the present invention, in handheld conformable bladder thermal delivery device 3400; in headband thermal delivery device(s) and/or in cheek thermal delivery device(s) from U.S. provisional patent application 63/390,926 filed July 20, 2022, by the same inventor (John Richard Taylor) as the present patent application, whose disclosures are incorporated by reference herein as if fully set forth herein, then the associated heat transfer member(s), medium(s), and/or elements) 3907 may be part of that given thermal delivery device 3911.

Whereas, in other embodiments, the given thermal delivery device 3911 and its associated heat transfer member(s), medium(s), and/or element(s) 3907, that given thermal delivery device 3911 may not comprise the associated heat transfer member(s), medium(s), and/or element(s) 3907 as part of that given thermal delivery device 3911. For example, and without limiting the scope of the present invention, when the given thermal delivery device 3911 is soaking-device 100 and/or the Hydroeffacer face soaking device (see e.g., U.S. utility patent 10667990), then the associated heat transfer member(s), medium(s), and/or element(s) 3907 may be an immersion liquid (e.g., immersion-liquid 180), such as, but not limited to, water; and that soaking-device 100 and/or Hydroeffacer face soaking device may not comprise the immersion liquid (e.g., immersion-liquid 180) (water); rather, that immersion liquid e.g., immersion-liquid 180) (water) may be added to and/or used with that soaking-device 100 and/or Hydroeffacer face soaking device during intended/normal use, as the associated heat transfer member(s), medium(s), and/or element(s) 3907. Such a scenario may also be the scenario for whole head immersion thermal delivery device(s) and/or face immersion thermal delivery device(s) from U.S. provisional patent application 63/390,926 filed July 20, 2022, by the same inventor (John Richard Taylor) as the present patent application, whose disclosures are incorporated by reference herein as if fully set forth herein; i.e., each of these given thermal delivery devices 3911 may use an immersion liquid (such as, but not limited, to water) as its associated heat transfer member(s), medium(s), and/or element(s) 3907 that gets added to the given thermal delivery device during intended use. However, in still other embodiments, when the immersion liquid includes (proprietary) ingredients (additives), then the associated heat transfer member(s), medium(s), and/or element(s) 3907 may be a part of that given thermal delivery device 3911 and/or part of a system and/or a method that utilizes that associated heat transfer member(s), medium(s), and/or element(s) 3907 with the added ingredients (additives).

Continuing discussing FIG. 41, in some embodiments, skin/body portion contact means 4111 may be a portion of a given thermal delivery device 3911 that directly physically (removably) contacts (touches) skin and/or a body portion 3909 of subject 3905 (user 190). In some embodiments, skin/body portion contact means 4111 may be a portion of a given thermal delivery device 3911 that directly physically (removably) contacts (touches) skin and/or a body portion 3909 of subject 3905 (user 190) and that is involved in heat/cool transfer to skin and/or a body portion 3909 of subject 3905 (user 190). In some embodiments, heat transfer member(s), medi- um(s), and/or element(s) 3907 and skin/body portion contact means 4111 may refer to a same structure, part, component, element, portion thereof, combinations thereof, and/or the like of a given thermal delivery device 3911; and in such embodiments, then reference numerals 3907 and 4111 may be used interchangeably. In some embodiments, when heat transfer member(s), medi- um(s), and/or element(s) 3907 may be a solid, a gel, beads, portions thereof, combinations thereof, and/or the like, then heat transfer member(s), medium(s), and/or element(s) 3907 may be a same structure, part, component, element, portion thereof, combinations thereof, and/or the like with respect to skin/body portion contact means 4111. For example, and without limiting the scope of the present invention, (conformable) bladder 3405 (of handheld-thermal-device 3400) may be an example of both skin/body portion contact means 4111 and of heat transfer members), medium(s), and/or element(s) 3907. Whereas, and in contrast, with respect to soakingdevice 100, there the heat transfer member(s), medium(s), and/or element(s) 3907 may be the immersion-liquid 180 and there may be no skin/body portion contact means 4111 that is involved in thermal heat/cool transfer (but there may be skin/body portion contact means 4111 used in other uses, such as headrest 1800 or mouthpiece 1705).

Continuing discussing FIG. 41, in some embodiments, heating and/or cooling means 4109 may be configured to provide heating and/or cooling to portion 3909, via heat transfer member(s), medium(s), and/or element(s) 3907 and/or via skin/body portion contact means 4111.

Continuing discussing FIG. 47, in some embodiments, head strap(s) 4605 may be configured to removably secure containment vessel 4701 to a head 191 of subject 3905 (user 190). In some embodiments, face immersion thermal delivery device 4700 and/or containment vessel 4701 may comprise one or more head strap(s) 4605. In some embodiments, head strap(s) 4605 may be configured to fit around sides, a top, and/or a back/rear of the head 191 of subject 3905 (user 190). In some embodiments, head strap(s) 4605 may be attached to an edge (e.g., rigid portions of gasketed rim 4603) of containment vessel 4701 and/or to each other.

Continuing discussing FIG. 47, in some embodiments, a distal terminal end of tubing 3451 may be designated as terminal end of tubing 4703. In some embodiments, terminal end of tubing 4703 may be configured to (removable) attachment to heating and/or cooling means 4109, pump 3453 and/or to reservoir 3455.

As discussed herein, at least one invention and/or embodiment disclosed herein may be characterized as a method of inducing 3901 a desired-and/or- intended-outcome 3903 in subject 3905 by touching heat-transfer-element (medium) 3907 against portion 3909 of subject 3905. In some embodiments, heat-transfer-element (medium) 3907 may be at least initially at a different temperature from a surface of portion 3909 of subject 3905. In some embodiments, the tempera- ture(s) of heat-transfer-element (medium) 3907 may be maintained, controlled, and/or generated by thermal means (thermal delivery means and/or thermal delivery device) 3911. See e.g., FIG. 39 and FIG. 40.

In some embodiments, this method of FIG. 39 may be further framed in the following manner. For example, and without limiting the scope of the present invention, this method may be a method of causing release of at least one type of neurotransmitter in an animal 3905 by, at least in part, heating portion 3909 of animal 3905, cooling portion 3909, or alternating between heating and cooling of portion 3909 - using thermal delivery device 3911.

In some embodiments, this method of FIG. 39 may be further framed in the following manner. For example, and without limiting the scope of the present invention, this method may be a method of (indirectly) stimulating a vagus nerve of human 3905 by stimulating trigeminal nerve 3800 of human 3905, wherein the trigeminal nerve 3800 is stimulated, at least in part, by heating the trigeminal nerve 3800, cooling the trigeminal nerve 3800, or alternating between heating and cooling of trigeminal nerve 3800 - using thermal delivery device 3911. In some embodiments, the trigeminal nerve 3800 may (also) be stimulated via electrodes (e.g., electrode(s) 2915) that may electrify an immersion-liquid (e.g., immersion- liquid 180). In some embodiments, this method of (indirect) vagus nerve stimulation may be done without direct electrical stimulation of the vagus nerve.

In some embodiments, this method of FIG. 39 may be further framed in the following manner. For example, and without limiting the scope of the present invention, this method may be a method of transdermal delivery of at least one chemical (chemical species, chemicaladditive, and/or additive) across portion 3909 of skin by applying the at least one chemical to an exterior portion of the skin of portion 3909 and by, at least in part, heating portion 3909 of the skin, cooling portion 3909 of the skin, or alternating between heating and cooling of portion 3909 of the skin - using thermal delivery device 3911. In some embodiments, applying the at least one chemical to the exterior portion of the skin of portion 3909 may comprise placing (putting) the at least one chemical within the immersion-liquid (e.g., within immersion-liquid 180). In some embodiments, this method of FIG. 39 may be further framed in the following manner. For example, and without limiting the scope of the present invention, this method may be a method that is configured for providing thermal therapy to face 192 of human 190 (3905) to induce a desired outcome 3903 in human 190 (3905). In some embodiments, this method may comprise a step (a) of exposing at least some of face 192 within immersion-liquid 180 for at least a minimum amount of time, while immersion-liquid 180 is within a temperature-range and while immersion-liquid 180 is within a vessel (e.g., the vessel portion of soaking-device 100) (e.g., so that face 192 may also be at least partially within this vessel portion), wherein during the step (a) front-of-neck 197 of human 190 (3905) is removably physically pressing up against flexiblemember 500 (neck-gasket 500) of the vessel (e.g., the vessel portion of soaking-device 100) in a manner that forms a watertight seal between flexible-member 500 (neck-gasket 500) and front- of-neck 197, wherein immersion-liquid 180 acts a heat transfer medium 3907 for the at least some of face 192. In some embodiments, with respect to this method, the thermal therapy may comprise: (1) heating face 192, (2) cooling face 192, or (3) alternating between heating and cooling face 192, wherein the heating and/or the cooling is done by immersion-liquid 180. In some embodiments, during execution of the step (a) this method may further comprise maintaining immersion-liquid 180 within the temperature-range by one or more of: insulating at least some of the vessel (e.g., the vessel portion of soaking-device 100), heating immersion-liquid 180, cooling immersion-liquid 180, or alternating between heating and cooling immersion-liquid 180. In some embodiments, the heating of immersion-liquid 180 and/or the cooling of immersion-liquid 180 may be done by one or more thermal means 3911, 4105, 4107, and/or 4109. In some embodiments, immersion-liquid 180 may comprise water. In some embodiments, immersion-liquid 180 may be at least predominantly a liquid throughout the temperature-range experienced during execution of the step (a) of this method (and at standard sea-level Earth atmospheric pressures). In some embodiments, immersion-liquid 180 may comprise a liquid and at least one chemicaladditive, wherein that at least one chemical-additive may be within that liquid. In some embodiments, the at least one chemical-additive may be predetermined and/or may be selected from one or more of: a chemical, a salt, an ion, a molecule, a medicine, a medicament, a pharmaceutical, a carbohydrate, an amino acid, a peptide, a protein, a nucleic acid, a string of deoxyribonucleic acid, a string of ribonucleic acid, a fatty acid, a hormone, an antibiotic, a moisturizer, a skin bleacher, an oxidizer, a skin peal, a skin mud, a skin clay, a liposome, portions thereof, combinations thereof, and/or the like. In some embodiments, the at least one chemical-additive may be one or more of: naturally occurring, synthetic, human made, water soluble, fat soluble, partially water soluble, partially fat soluble, plant derived, algae derived, animal derived, bacteria derived, fungus derived, archaebacteria derived, protozoan derived, portions thereof, combinations thereof, and/or the like. In some embodiments, during execution of the step (a) at least some of the at least one chemical-additive may be transdermally delivered across a portion of the at least some of face 192 (and which may bypass the BBB in some embodiments). In some embodiments, during execution of the step (a), the flexible-member 500 (neck-gasket 500) does not cover over nor touch a rear portion of the neck (back-of-neck 193) of human 190 (3905), wherein the rear portion (back-of-neck 193) may be disposed opposite from the front-of-neck 197. In some embodiments, at least some of the flexible-member 500 (neck-gasket 500) may be waterproof. In some embodiments, during execution of the step (a), a remainder of a body of human 190 (3905), below the neck and not including face 192, is not in physical contact with immersion-liquid 180 (unless human 190 [3905] decided to put their hand and/or finger into immersion- liquid 180). In some embodiments, the remainder of the body of human 190 (3905) may be dry during execution of the step (a) of the method. In some embodiments, during execution of the step (a), for at least a portion of the minimum amount of time, the method further comprises use of one or more accessories. In some embodiments, the one or more accessories comprises one or more of: a breathing-apparatus (such as, but not limited to, breathing-apparatus 1700, a breathing apparatus of a Hydroeffacer, a snorkel, and/or the like) that is configured to permit human 190 (3905) to breathe while the at least some of face 192 is immersed within immersion-liquid 180; a headrest (such as, but not limited to, headrest 1800, a headrest [head rest] of a Hydroeffacer, and/or the like) that is configured to support head 191 of human 190 (3905) while the at least some of face 192 is immersed within immersion-liquid 180; a means for releasing of gas bubbles (such as, but not limited to, gas-line-tubing 2709) into immersion-liquid 180 while the at least some of face 192 is immersed within immersion-liquid 180; electrodes (such as, but not limited to, electrode(s) 2915) for electrifying immersion-liquid 180 while the at least some of face 192 is immersed within immersion-liquid 180 to provide some electro-stimulation to the at least some of face 192; and/or a means of emitting electromagnetic radiation (such as, but not limited to, lights, LEDs, and/or light-source 1500) into immersion-liquid 180 while the at least some of face 192 is immersed within immersion-liquid 180. In some embodiments, prior to the method executing the step (a), the method may further comprise a step of placing the at least some of face 192 within immersion-liquid 180 that is residing within the vessel (e.g., the vessel portion of soaking-device 100). In some embodiments, the vessel e.g., the vessel portion of soaking-device 100) may comprises a top that is at least substantially open.

In some embodiments, the minimum amount of time of the step (a) may be selected from three seconds to three hours. In some embodiments, the minimum amount of time may be split into two or more durations of time.

In some embodiments, characterizing of “heating” or of “cooling” of portion 3909 (e.g., face 192) may be with respect to: a normal average internal body temperature of human 190 (3905) which is typically cited at 37 degrees Celsius (98.6 degrees Fahrenheit); or with respect to how human 190 (3905) might perceive a temperature-range of immersion-liquid 180; and/or whether or not heating means 4105, cooling means 4107, and/or heating and/or cooling means 4109 may be activated or not. For example, and without limiting the scope of the present invention, any temperature-range of immersion-liquid 180 above 37 degrees Celsius (98.6 degrees Fahrenheit) may be characterized as “heating” of portion 3909 (e.g., face 192), if portion 3909 (e.g., face 192) is immersed within immersion-liquid 180 - because thermodynamically heat moves from warmer regions to cooler regions (but once portion 3909 [e.g., face 192] is removed from immersion-liquid 180 such a temperature-range could be characterized as cooling due to evaporative cooling of the skin in the air). For example, and without limiting the scope of the present invention, any temperature-range of immersion-liquid 180 below 37 degrees Celsius (98.6 degrees Fahrenheit) may be characterized as “cooling” of portion 3909 (e.g., face 192) - because thermodynamically heat moves from warmer regions to cooler regions. For example, and without limiting the scope of the present invention, a temperature-range of immersion-liquid 180 of 85 to 97 degrees Fahrenheit (29.4 to 36.1 degrees Celsius) may be perceived as warm to cool by some humans. One hundred (100) degrees Fahrenheit (37.8 degrees Celsius) water is often perceived as warm by humans; whereas, water temperatures at 106 degrees Fahrenheit (41.1 degrees Celsius) or higher often induce pain and a sensation of hot (hotness) in humans.

In some embodiments, when immersion-liquid 180 may be actively heated, its temperature-range may be perceived as warm to hot, and/or tolerably painful by human 190 (3905). In some embodiments, when immersion-liquid 180 may be actively heated, its temperature-range may be 95 to less than 120 degrees Fahrenheit (35 to less than 48.9 degrees Celsius). In some embodiments, a maximum of the temperature-range when immersion-liquid 180 may be actively heated, may be targeted for 108.5 degrees Fahrenheit (42.5 degrees Celsius). However, when the heat transfer fluid 3907 may be a gas (e.g., air and/or oxygen), then higher temperatures than 108.5 degrees Fahrenheit (42.5 degrees Celsius) may be utilized. Immersion-liquid 180 is only one example of heat transfer fluid 3907.

In some embodiments, when immersion-liquid 180 may be actively cooled, its temperature-range may be perceived as cool to cold, and/or tolerably painful by human 190 (3905). In some embodiments, when immersion-liquid 180 may be actively cooled, its temperature-range may be 70 to above 32 degrees Fahrenheit (21.1 to above 0 degrees Celsius). In some embodiments, a minimum of the temperature-range when immersion-liquid 180 may be actively cooled, may be targeted for 59 degrees Fahrenheit (15 degrees Celsius). However, when the heat transfer fluid 3907 may be a gas (e.g., air and/or oxygen), then lower temperatures than 59 degrees Fahrenheit (15 degrees Celsius) may be utilized.

For example, and without limiting the scope of the present invention, the desired outcome 3903 in human 190 (3905) may be selected from one or more of: a greater release of at least one type of neurotransmitter as compared to when human 190 (3905) is not being treated by the method; improving skin health of the at least some of face 192; reducing severity of at least one skin wrinkle of the at least some of face 192; reducing acne severity of the at least some of face 192; reducing rash severity of the at least some of face 192; increased healing of a wound (a cut, puncture, and/or laceration) of at least a portion of the at least some of face 192; a reduction in bruising (and/or swelling) of at least a portion of the at least some of face 192; a reduction in stress of human 190 (3905); a reduction in anxiety of human 190 (3905); a reduction in depression of human 190 (3905); an increased feeling relaxation, calmness, and/or contentment; as at least a partial treatment for addiction; as at least a partial treatment for substance abuse; trans- dermal delivery of at least one chemical (chemical-additive) within immersion-liquid 180 across the at least some of face 192; a reduction in headache severity of human 190 (3905); a reduction in sinus pressure of human 190 (3905); an increase in metabolism as compared to when human 190 (3905) is not being treated by the method; producing brown fat and/or browning of white adipose tissue (WAT); improving cardiovascular health of human 190 (3905); reducing pain of human 190 (3905); as a least a partial treatment of myocardial infarction (heart attack), transient ischemic attack (TIA), and/or stroke; as at least a partial treatment for blepharitis (that is commonly known as dry eye); cleaning of an exterior of an eye of human 190 (3905); encouraging removal of an object from an exterior of the eye of human 190 (3905); as at least a partial treatment for diabetes; as at least a partial means of preventing diabetes; or improved quality of sleep when the method is carried out prior to sleeping. In some embodiments, the desired outcome 3903 (the desired and/or intended outcome 3903) may be as compared to when human 190 (3905) is not being treated by the thermal therapy method (and/or the hydrotherapy method).

In some embodiments, soaking-device 100 and Hydroeffacer (e.g., face soaking device from U.S. utility patent 10,667,991) may share some features and also may differ on some features. For example, and without limiting the scope of the present invention, with respect to differences between soaking-device 100 and the Hydroeffacer, the side panels (side walls) (e.g., front-panel 103, rear-panel 105, and/or side-panels 107) and/or floor-and-sidewalls 101 of soaking-device 100 may initially come from flat/planar sheet/panel source materials (at least some of which may be off-the-shelf); whereas, side panels (side walls) and/or a floor of the Hydroeffacer may be injection molded (see e.g., FIG. 2G of U.S. utility patent 10,667,991). For example, and without limiting the scope of the present invention, with respect to differences between soakingdevice 100 and the Hydroeffacer, the vessel portions of soaking-device 100 (that may contain the immersion-liquid 180) may be formed from three separate and different components e.g., frontpanel 103, rear-panel 105, and floor-and-sidewalls 101); whereas, the vessel portion of the Hydroeffacer (that may contain its immersion liquid) may be formed from one integral tub member (see e.g., inner vessel member 200a of FIG. 2G of U.S. utility patent 10,667,991). For example, and without limiting the scope of the present invention, with respect to differences between soaking-device 100 and the Hydroeffacer, at least some control of soaking-device 100 may be from a removable tower 2700 member; whereas, controls of the Hydroeffacer may be integrated into (an upper rear portion of) a vessel (hull) member and may generally be non-removable (see e.g., membrane-switch-receiving-recess 1021 of inner vessel member 200a of FIG. 2G of U.S. utility patent 10,667,991). In terms of similarities, both soaking-device 100 and the Hydroeffacer may be used as thermal delivery devices 3911 for thermally soaking and/or treating the face 192, a hand, a foot, a lower arm, a lower leg, a limb, fingers, toes, at least a portion of the head 191, a portion thereof, combinations thereof, and/or the like, of user 190, with a temperature controlled immersion liquid.

In some embodiments, when heat transfer fluid 3907 may be at least a gas such as, but not limited to, air and/or oxygen, the gas heat transfer fluid 3907 may be heated, cooled, heated and/or cooled, humidified, dehumidified, portions thereof, combinations thereof, and/or the like. In some embodiments, when heat transfer fluid 3907 may be at least a gas such as, but not limited to, air and/or oxygen, the gas heat transfer fluid 3907 may be breathable by a human 190 (subject 3905); and in some embodiments, the given thermal delivery device 3911 that may be utilizing such a breathable gas heat transfer fluid 3907, may or may not comprise a breathing apparatus (breathing-apparatus). In some embodiments, a breathing apparatus (breathingapparatus) may still be employed to minimize heated and/or chilled air / oxygen from reaching lungs of user 190 (subject 3905) even when the gas heat transfer fluid 3907 may be breathable. In some embodiments, whole head (immersion) thermal delivery device(s) 3500, 4400, 4450, 4475, and/or 4500; and/or (whole) face immersion thermal delivery device(s) 4600, 4650, and/or 4700 may employ (utilize) a heat transfer fluid 3907 that may be a liquid, a gas, portions thereof, combinations thereof, and/or the like. In some embodiments, that gas may be a breathable gas, such as, but not limited to air and/or oxygen. In some embodiments, when whole head (immersion) thermal delivery device(s) 3500, 4400, 4450, 4475, and/or 4500; and/or when (whole) face immersion thermal delivery device(s) 4600, 4650, and/or 4700 may employ (utilize) a breathable gas as the heat transfer fluid 3907, then such thermal delivery device(s) 3911 may nor may not comprise a breathing apparatus (breathing-apparatus).

In some embodiments, a system and/or a kit may comprise at least one soaking-device 100 and one or more of: a breathing-apparatus and/or a headrest. In some embodiments, the breathing-apparatus may be selected from one or more of: breathing-apparatus 1700; any breathing apparatus or the like shown and described in U.S. utility patent 10667990, U.S. utility patent 10449341, U.S. utility patent 10667991, U.S. utility patent 11154697, U.S. design patent D863575, U.S. design patent D863576, U.S. design patent D864403, U.S. design patent D889675, and/or in U.S. design patent D916303; a snorkel used for snorkeling or the like; portions thereof; combinations thereof; and/or the like. In some embodiments, the headrest may be selected from one or more of: headrest 1800; any headrest (head rest) or the like shown and described in U.S. utility patent 10667990, U.S. utility patent 10449341, U.S. utility patent 10667991, U.S. utility patent 11154697, U.S. design patent D863575, U.S. design patent D863576, U.S. design patent D864403, U.S. design patent D889675, and/or in U.S. design patent D916303; portions thereof; combinations thereof; and/or the like. In some embodiments, soaking-device 100 may comprise at least one breathing-apparatus 1700 and/or at least one headrest 1800.

In some embodiments, front-panel 103; rear-panel 105; side-panels 107; bottom-panel 113; and/or thermal-break 1309 may be all be formed, cut, extruded, and/or machined (e.g., CNC) from planar sheet stock material, such as, but not limited to, planar sheet material of: plastic, foam plastic, metal, metal alloys, fiberglass, ceramic, wood, laminates, combinations thereof, portions thereof, and/or the like.

In some embodiments, the predetermined shape of floor-and-sidewalls 101 may be formed/made from planar sheet stock material by bending, rolling, stamping, molding, combinations thereof, portions thereof, and/or the like of that initial planar sheet stock material.

In some embodiments, the predetermined shape of handle(s) 1300 may be formed/made from planar sheet stock material by extrusion, bending, rolling, stamping, molding, combinations thereof, portions thereof, and/or the like of that initial planar sheet stock material.

In various embodiments, any plastics used in the thermal delivery devices 3911 discussed herein may be suitable for injection molding. At least some such plastics used in the material(s) of construction for the thermal delivery devices 3911 discussed herein, such as, but not limited to, soaking-device 100 or portions thereof, if any, may be selected from acrylic, acrylonitrile- butadiene styrene (ABS), polyvinyl chloride (PVC), polycarbonate, nylon, polypropylene, polyethylene {e.g., HDPE), with or without strengthening fibers, in expanded foam variation thereof or not, combinations thereof, portions thereof, and/or the like.

Note with respect to the materials of construction, it is not desired nor intended to thereby unnecessarily limit the present invention by reason of such disclosure.
