Working up a sweat on hot, muggy days or while exercising is only natural and, in fact, healthy. Sweating is the body’s way of cooling down. But sometimes, the body sweats too much, which is the case for people who have a medical condition called hyperhidrosis.

In people with hyperhidrosis, the body’s 2 to 4 million sweat glands are overactive, causing profuse perspiration at times when others would sweat lightly (if at all). They sweat a lot even when weather or physical activity don’t warrant it. If this is the case for you or a loved one, you might consider talking to a dermatologist about it because there are treatments that can help.

If you find yourself staining your shirts on a daily basis, feeling embarrassed to give a handshake because of dripping palms, sweating in the midst of a winter blizzard or coming home to a puddle of sweat in your sneakers, it may be the time to speak with a board- certified dermatologist for an evaluation. Sometimes the condition is caused by medications or a medical condition, but most of the time there is no underlying cause. 

At Yale Medicine Dermatology, we understand that hyperhidrosis can interfere with your day-to-day life and cause embarrassment. We do a thorough evaluation to determine if there is a cause of sweating and then customize a treatment regimen that fits your lifestyle.
