The term sweda means sweat or perspiration. It is one among three metabolic excretory products ([[mala]]) like urine ([[mutra]]) and stools ([[purisha]]). These are also known as [[dushya]] (which get vitiated). [A.Hr.Sutra Sthana 1/13]<ref name= Hridaya > Vagbhata. Ashtanga Hridayam. Edited by Harishastri Paradkar Vaidya. 1st ed. Varanasi: Krishnadas Academy;2000.</ref> Excretory products ([[mala]]) are important in human physiology. They are formed in routine physiological and metabolic activities in the body. It is important to cleanse or purify body by removing the wastes. If accumulated, the [[mala]] have ability to pollute [[dosha]] and [[dhatu]] of the body.
Perspiration or sweating (sweda) is important for removing wastes formed in skin and maintain body temperature i.e. thermoregulation. Sweda is basically the end product of [[meda dhatu]] metabolism. This article describes concept and applications of sweda in [[Ayurveda]] and contemporary sciences.

==Derivation & definition==
Literal meaning of sweda is to cook or to steam. It is the perspiration produced due to exercise or heat. The word sweda is derived from the verb ‘svid’ meaning exudate or perspiration from the body parts as a result of gharma or heat. [Vachaspatyam]<ref>VCP Cologne Scan [Internet]. [cited 2022 Jun 30]. Available from: https://www.sanskrit-lexicon.uni-koeln.de/scans/csl-apidev/servepdf.php?dict=vcp&page=5393</ref> The terms like sweating, sweat, perspiration, warmth, vapor, steam etc. [Monniere Williams dictionary]<ref>MW Cologne Scan [Internet]. [cited 2022 Jun 30]. Available from: https://www.sanskrit-lexicon.uni-koeln.de/scans/csl-apidev/servepdf.php?dict=mw&page=1285</ref>
Sweda is a part of water or watery exudate within the entire body excreted through the hair pockets (lomakupa).[Cha.Sa.[[Sharira Sthana]]7/15), [Arunadatta on [A.Hr.Sharira Sthana 3/36]<ref name=Hridaya/>
It is closely regulated by heat in the body (ushma). Sweda is formed during the metabolism of [[meda dhatu]] and as part of water/fluid component (udaka) in the body. [Chakrapani on Cha.Sa.[[Chikitsa Sthana]] 15/18-19]
In contemporary medical dictionaries, the literal meaning of the word ‘sweat’ is perspire or exudation or moisture from the sweat pores.<ref>“Sweat.” Merriam-Webster.com Dictionary, Merriam-Webster, https://www.merriam-webster.com/dictionary/sweat. Accessed 28 Jun. 2022.</ref>

'''Panchabhautika constitution'''
Sweda has dominance of [[jala]] and [[teja mahabhuta]]. Some scholars consider it as [[jala mahabhuta]] dominant.[Chakrapani on Su.Sa.Sutra Sthana 15/7)<ref name= Susruta> Sushruta. Sushruta Samhita. Edited by Jadavaji Trikamji Aacharya. 8th ed. Varanasi: Chaukhambha Orientalia;2005.</ref> It is listed among the watery components in body. [Cha.Sa.[[Sharira Sthana]] 7/16] [A.Hr.Sharira Sthana 3/4]<ref name=Hridaya/>
==Physiology of formation and excretion==
Sweda is produced as byproduct in metabolism of [[meda dhatu]] [Cha.Sa.[[Chikitsa Sthana]] 15/18], in channels of transformation and transportation of [[meda dhatu]] (medovaha srotasa).(Chakrapani on Cha.Sa.[[Sutra Sthana]] 28/4] Sweda bestows moistness and softness of the skin. It is a part of waste part (kitta bhaga) of the metabolized food. [Cha.Sa.[[Sutra Sthana]] 28/4]
Sweda or sweat is basically the fluid element excreted through sweat pores due to heat or activity along with dissolved minerals and solids. Its formation is regulated by means of external temperature, fomentation or heat treatments. The main seat of channels of formation and transportation of sweat (swedavaha srotas) are [[meda dhatu]] and the small pores on the skin (romakoopa). It depends on excess heat in body. [Cha.Sa.[[Sharira Sthana]] 7/14]
