Sweating is the way the body regulates its temperature. Sweat is produced by sweat glands (2-4 million) located in the skin in various parts of the body. The sweat glands are found in large numbers on the soles of the feet, the palms, the forehead and cheeks, and in the armpits. The activity of sweat glands is under the control of the sympathetic nervous system and is involuntary.
Sweating a lot is normal when it is hot or when you exercise, are anxious or have a fever. It is also natural to sweat more during puberty and menopause. In people who suffers from excessive sweating or hyperhidrosis the sweat glands overreact to stimuli and are generally overactive, producing more sweat than is necessary. Excessive sweating or hyperhidrosis is defined as sweating beyond the physiological need of the body.
Hyperhidrosis or excessive sweating is affecting 3% of the population. Palmar hyperhidrosis is the most common form of hyperhidrosis, causing excessive sweating of the hands. Hyperhidrosis can also cause excessive foot, underarm and facial sweating. Sweating is often uncontrollable, embarrassing and not anticipated. Hyperhidrosis has devastating emotional effects on oneâ€™s individual life. Affected people are constantly aware of their condition and try to modify their lifestyle to accommodate this problem. This can be disabling in professional, academic and social life.
