Palmar Hyperhidrosis is the medical term for excessive sweating in the palms. Sweating is necessary for our body as it maintains core body temperature. The human body has 4 million sweat glands distributed on all areas of the skin, with higher concentrations found on the palms, soles, axillae and face.
Sweating has both thermoregulatory and emotional variants. Palmar Hyperhidrosis is a medical problem that involves more sweating than what is required by our body. Palmar Hyperhidrosis is caused by over-activity of the sweat glands and is present in 1% of the population and a family history is present in 30% to 50% of patients suggesting a genetic component.
