3 Significant Functions Of Sweating
Before intentionally seeking out sweating to enjoy the health benefits, speak to a physician to ensure your methods are appropriate for your level of fitness and health. Helping the body cool down is sweating’s the primary benefit, but it’s not the only one.

3 Significant functions of sweating
1. Cools the Body Down
Sweating is a method for releasing excess heat; when your body begins to sweat, it’s trying to regulate your temperature and make sure that your body doesn’t become overheated. The action of sweating, and then the sweat, in turn, evaporating from the skin, are what helps cool the body down. This is a considerable benefit of sweating and one that provides meaningful protection to your body.
- Though some people may get embarrassed by their own sweating, this is simply a sign that their body is efficiently dealing with heat.
- People who can’t sweat (a rare condition called Cystinosis) have to take extreme care to ensure they don’t find themselves in situations where they will get overheated.
2. Expels Toxins
While some health experts (including Dr. Mehmet Oz and Dr. Mike Roizen) suggest sweating as a means to detoxify the body, the idea that sweating expels harmful toxins from the body is a controversial one. For example, while the School of Medicine and Health at the University of Wisconsin-Madison suggests that the use of a sauna for sweating is an effective way to expel toxins from the body, Harvard Medical School has a different stance, stating that saunas are generally safe but don’t necessarily provide any health benefits beyond relaxation.
- One study did not provide any conclusive evidence with regards to sweat being a method for expelling toxins from the body but did suggest that further study is needed.
- Even skeptical health experts state that seeking out sweating to detoxify the body using methods like saunas and exercise is generally safe for healthy individuals, as long as the fluid lost is quickly replenished.
3. Fights Infection
Many health advocates make the broad claim that sweating helps the body fight infection and stay healthy. Research surrounding Dermcidin, a protein found on human skin, demonstrates supporting evidence for this claim.
Researchers in Europe say that Dermcidin jumps into action when it comes into contact with sweat and creates a natural antibiotic believed to be effective in treating tuberculosis and hospital superbugs. Sweat is needed to activate the natural healing properties of Dermcidin, making the act of sweating the way the body capitalizes upon this natural defense.
