Also found in: Dictionary, Thesaurus, Idioms, Encyclopedia, Wikipedia.
In high temperatures, during strenuous exertion, or in times of unusual emotional stress, the sweat output of the body may exceed several quarts per day. Even on a cool day without exertion or emotional stress, the body loses well over a pint of fluid in sweat. This latter kind of sweating is known medically as “insensible” perspiration because it is virtually unnoticeable; as the sweat reaches the surface of the skin, it evaporates immediately. When sweating becomes noticeable, it is known as “sensible” perspiration.
The chief function of sweat glands and perspiration is to maintain the body temperature at a constant level. Thus the skin is cooled as perspiration evaporates. The blood in the capillaries of the skin likewise is cooled before it courses back into the body. The sweat glands have a minor excretory function. Perspiration contains water, sodium chloride, and small amounts of urea, lactic acid, and potassium ions. It also contains antibacterial substances that defend the body against infection.
Synonym(s): diaphoresis, sudation, sweating.
