Hyperhidrosis is a medical condition in which a person exhibits excessive sweating, [1] [2] more than is required for the regulation of body temperature. [3] Although it is primarily a physical burden, hyperhidrosis can deteriorate the quality of life of the people who are affected from a psychological, emotional, and social perspective. [4]
Researchers have found evidence of frostbite in humans dating back 5,000 years, in an Andean mummy. Napoleon's Army was the first documented instance of mass cold injury in the early 1800s.

The obvious benefit is not sweating — or at least sweating less — at night. Brands say that there are a number of other gains to be made when sleeping with a cooling blanket.
The long history of research into the active and passive electrical properties of the skin by a variety of disciplines has resulted in an excess of names, now standardized to electrodermal activity (EDA). [1] [2] [3] The traditional theory of EDA holds that skin resistance varies with the state of sweat glands in the skin.
Anatomy of the human skin. Skin temperature is the temperature of the outermost surface of the body. Normal human skin temperature on the trunk of the body varies between 33.5 and 36.9 °C (92.3 and 98.4 °F), though the skin's temperature is lower over protruding parts, like the nose, and higher over muscles and active organs.
