How Sweating Is Good for Your Health

Slide 2 of 8

It keeps you cool

"Sweating is best known as the body's built-in mechanism for regulating its temperature," says dermatologist Adam Friedman, M.D., FAAD, attending physician at the Center for Dermatology, Cosmetic & Laser Surgery at Montefiore Medical Center in New York City. In fact, the main function of sweat is to cool your body as your core temperature rises while exercising, sitting in a sauna or working in the garden on a hot day. "Sweating helps your body can get rid of the excess heat so you don't boil over and overheat," says Friedman.  Sweating is so important to the body's natural cooling process that an inability to sweat could be life-threatening. "There is a condition called ectodermal dysplasia that leaves a person unable to sweat," says dermatologist Joel Schlessinger, M.D., immediate past president of the American Society of Cosmetic Dermatology and Aesthetic Surgery, and president of LovelySkin.com. "These people typically are unable to participate in sports because they overheat during intense exercise, which could have adverse effects on the heart and other body functions." Be thankful for your ability to sweat.
