Sweating

Definition

Sweating is the release of a salty liquid from the body's sweat glands. This process is also called perspiration.

Sweating is an essential function that helps your body stay cool. Sweat is commonly found under the arms, on the feet, and on the palms of the hands.

Considerations

How much you sweat depends on how many sweat glands you have. A person is born with about two to four million sweat glands. The glands start to become fully active during puberty. Women have more sweat glands then men, but men's glands are more active.

Sweating is controlled by the autonomic nervous system, the part of the nervous system that is not under your control. Because sweating is the body's natural way of regulating temperature, people sweat more when it's hot outside. People also sweat more when they exercise, or in response to situations that make them nervous, angry, embarrassed, or afraid.

Excessive sweating may also be a symptom of menopause.
