Excessive sweating, known as hyperhidrosis, can occur almost anywhere on the body, but excessive sweating is often localized to the hands or face (localized hyperhidrosis). Excessive sweating might be caused by a minor malfunction in the nervous system, and appears to be genetic. Regardless of the cause, excessive sweating can make you self-conscious and uncomfortable. The condition can impact the color and style of clothes you wear and influence the success of your career.
Normally, your nervous system activates sweat glands when your body temperature rises, creating an automatic cooling effect. In people with hyperhidrosis, however, the nerves that signal the sweat glands are overactive.
