What is hyperhidrosis?
Hyperhidrosis is the name given to excessive and uncontrollable sweating. Excessive sweating happens when a person sweats more than is necessary. Yes, it’s necessary to sweat. Sweating cools the body, which prevents us from overheating. People who have hyperhidrosis, however, sweat when the body does not need cooling.
