perspiration
Fluid given off by the skin as vapour by simple evaporation or as sweat actively secreted from sweat glands to evaporate and cool the body. When the body temperature rises, the sympathetic nervous system stimulates eccrine sweat glands to secrete water to the skin surface, where it cools the body by evaporation. Human eccrine sweat is essentially a dilute solution of sodium chloride with trace amounts of other plasma electrolytes. In extreme conditions, human beings may excrete several litres of such sweat in an hour.

perspiration
Evaporation of water from the skin surface, without the active secretion of sweat. This insensible perspiration is continuous and inevitable unless the environment is very humid, and in typical temperate zones it accounts for a loss of 300-400 ml daily in the average adult. Colloquially, the word perspiration is used euphemistically to avoid the smellier implications of sweat.
— Stuart Judge
See body fluids; sweating.
