The heat driving the vapor is called the heat of vaporization.
WebWhen the body temperature rises, the sympathetic nervous system stimulates the eccrine sweat glands to secrete water to the skin surface, where it cools the body by evaporation. … WebAs the sweat vaporises, energy (in the form of heat) passes into the environment, cooling the blood. This cooled blood gets circulated back to the heart and brain, and cools our core body temperature. The body loses excess heat via evaporation. This is why a day in the sun can feel so draining.
