in the skin. Perspiration, in most mammals, water given off by the intact skin, either as vapour by simple evaporation from the epidermis (insensible perspiration) or as sweat, a form of cooling in which liquid actively secreted from sweat glands evaporates from the body surface.

What is human sweat made of?

Sweat is a liquid made from 99% water and 1% salt and fat. Up to a quart of sweat evaporates each day. When your body becomes overheated, you sweat more. The evaporation of sweat from your skin cools your body down.

Why does perspiration happen?

This is the part of your nervous system that functions on its own, without your conscious control. When the weather is hot or your body temperature rises due to exercise or fever, sweat is released through ducts in your skin. It moistens the surface of your body and cools you down as it evaporates.
