Sweat or
perspiration occurs when the body’s core/internal temperature rises. This
phenomenon naturally occurs to help maintain and control the regular body
temperature of humans. Without sweat, the body will over heat and may lead to
heat exhaustion, heat stroke, or worst, death. Sweat glands that cover the
entire body are responsible for perspiration to maintain its homeostasis; as
the water in the sweat evaporates, the surface of the skin cools, regulating
and maintaining overall body temperature.
Perspiration/sweat
is mostly composed of water but it also contains some salts that are dissolved
and evaporated as well on the skin.
