Swedana (sudation) is a process in which the individual is subjected to therapeutic sweating. It is considered an essential prerequisite to Panchakarma (purification therapy involving five procedures) in [[Ayurveda]]. Swedana is intended to remove excessive vata and kapha dosha and is contraindicated in pitta disorders. The extent and intensity of swedana depends upon various factors such as physical strength, severity of dosha, season, site, age etc. There are specific indications and contraindications for swedana karma and the optimal signs should be strictly followed for the procedure. There are many agents to induce sweating which can be broadly divided into sagni sweda (sweating induced with the help of fire) and niragni sweda (induced without using fire). Bolus fomentation, steam fomentation, tub fomentation and poultice fomentation are some of the very common types of swedana procedures. There are thirteen varieties of fomentations (prevalent in the olden days) that involve direct usage of heat derived from fire, and ten methods without fire. Swedana is an effective therapeutic method in [[Ayurveda]] and is the focus of study in this chapter. </div>

− | As per [[Ayurveda]], the functioning of the universe depends upon ''agni'' and ''soma'' which symbolize sources of hot and cold energy. ''Uttarayana'' (northward sojourn of sun) and ''dakshinayana'' (southward sojourn of sun) are together responsible for maintaining homeostasis on this planet. This homeostasis is also mirrored in the individual through the concept of ''loka purusha samanya siddhantha'' (that the individual is a microcosm of the universe, the macrocosm). The ''purusha'' (individual human being) imbibes this energy and confines it in the ''sharira'' (body) as ''pitta''. This ''pitta'' controls, or rather regulates, the ''ushmanattva'' (core body temperature) of the body ([[Charak Samhita]] [[Sutra Sthana]] 12/11). It is responsible for all the metabolic processes at the cellular level and digestion at the level of the gut. ''Pitta'' is the contributor of ''ushna guna'' (warmth) to the body. The stimulator (''preraka'') of ''pitta'' is ''vata'' (the accelator-''sameerano agnehe'' ([[Charak Samhita]] [[Sutra Sthana]] 12). ''Vata'', in association with ''pitta'' and ''kapha'', maintains the normal core body temperature by controlling the heat regulating system and balancing the ''sheeta'' and ''ushna guna''. | + | As per [[Ayurveda]], the functioning of the universe depends upon ''agni'' and ''soma'' which symbolize sources of hot and cold energy.

| Contemporary science believes that heat has a beneficial effect (through thermotherapy, for instance) on pain relief. Effect of heat on pain is mediated by heat-sensitive channels. These channels respond to heat by increasing intracellular calcium (Ca). An increase in intracellular Ca generates action potentials that increase the stimulation of sensory nerves. These channels are a part of a family of receptors called TRPV receptors. TRPV1 and TRPV2 channels are sensitive to noxious heat, while TRPV4 channels are sensitive to normal physiological heat. These channels have certain characteristics in common, such as sensitivity to menthol, etc. Multiple binding sites allow a number of factors to activate these channels. Once activated, they can also inhibit the purin pain receptors. These receptors, termed as P2X2 and P2Y2, are mediated pain receptors located in the peripheral small nerve endings. For peripheral pain, heat can directly inhibit pain. However when pain is originating from deeper tissues, heat stimulates peripheral pain receptors that can alter what can be termed as “gating” in the spinal cord and reduce the sensation of deep pain. Another effect of heat is its ability to increase circulation. These same TRPV1 and TRPV4 receptors, along with nociceptor, increase blood flow in response to heat. The initial response to heat is mediated through the sensory nerves that release substance P and calcitonin-related peptide to increase circulation. After approximately one minute, Nitric Oxide is produced in vasculature endothelial cells and is responsible for sustained response of circulation to heat. This increase in circulation is considered to be essential in tissue protection from heat and repair of damaged tissue. Thermotherapy is of two types: dry and moist. A study was conducted to assess the effect of moist and dry heat on delayed onset of muscle soreness. Moist heat not only had similar benefits as dry heat but in some cases was more beneficial, requiring only 25% of time for application as dry heat. This study was conducted on quadriceps muscles. The study also witnessed immediate (and maximum) reduction in pain on application of moist heat, since moist heat penetrates deeper tissues faster than dry heat. Also, dry heat draws out moisture from the areas of application leaving them dehydrated, unlike moist heat. | | Contemporary science believes that heat has a beneficial effect (through thermotherapy, for instance) on pain relief.

− | For some of the disorders mentioned above that are ''sweda sadhya, mridu sweda'' alone should be performed. If the disease is ''sweda asadhya'', it’s better to avoid administering ''swedana'' to these areas. This indicates that utmost care has to be taken when it comes to applying fomentation to vital areas as well as fomenting the whole body. Various ''acharyas'' suggest using ''dravyas'', or medicated formulations, to shield or protect vital organs from any adverse affects of ''swedana''. ''Gangadhara'' recommends the use of ''sheeta veerya dravyas'', in this context, while administering ''mridu sweda'' to these vital parts, and Chakrapani also advises the use of these ''dravyas'' as protective measures of those parts while performing ''swedana''.

| Regarding eyes, the scientific community is interested in knowing more about the side effects of transpupillary thermotherapy (TTT). A study conducted on normal mouse retina reveals that retinas treated with a power of 70 mW exhibited progressive retinal damage that was almost exclusively restricted to the photo-receptors. In those cases, early damage to the outer segments of the photo-receptors was seen one day after the thermotherapy and saw degeneration of outer nuclear layer after five days. At the same time, an accumulation of pigmented cells, presumably of macrophages, was seen in the sub-retinal space. No apparent damage was seen in the RPE or choroid. Today, researchers are considering the importance of using sub-threshold effects while applying TTT to patients with neurovascular age-related macular degeneration.<ref>A.P. Kvanta, P.

The most common functional effect of heat acclimation is a change in the effector activation being shifted downwards.

| Thirteen types of ''agnisweda'' mentioned in [[Charak Samhita]] are based on four principles of heat transfer, namely, conduction, convection, radiation, and evaporation. Conduction is the transfer of heat between two surfaces that are in direct contact with each other and depends on the temperature gradient between body & surface, the total body surface area, velocity of the cutaneous blood flow & thickness of subcutaneous insulating tissue. Examples of ''agnisweda'' that leverage conduction include ''sankara, prastara, parisheka, avagaha,'' and ''ashmaghna''. | | Thirteen types of ''agnisweda'' mentioned in [[Charak Samhita]] are based on four principles of heat transfer, namely, conduction, convection, radiation, and evaporation.

Hence five minutes is the minimal period for which the patient should be kept in a supine posture, preferably at the same place.

| Normal thermoregulation in a human body consists of an important voluntary regulating mechanism termed as behavioral control wherein the person adopts various postures (fetal posture), food habits (like alcohol derivatives), exclusive clothings (woolen sweaters) or passively attains certain emotional states (like anger, fear which stimulates sympathetic nervous system with release of epinephrine & norepinephrine that increases BMR which in turn increases heat production) which significantly modulates the core temperature as a response to changing environmental conditions. Thus ''niragnisweda'' corresponds to adaptive mechanisms of human beings. | | Normal thermoregulation in a human body consists of an important voluntary regulating mechanism termed as behavioral control wherein the person adopts various postures (fetal posture), food habits (like alcohol derivatives), exclusive clothings (woolen sweaters) or passively attains certain emotional states (like anger, fear which stimulates sympathetic nervous system with release of epinephrine & norepinephrine that increases BMR which in turn increases heat production) which significantly modulates the core temperature as a response to changing environmental conditions.
