Perspiration, commonly known as sweating, is the process by which the body releases moisture through the skin. This occurs primarily through sweat glands, which are distributed throughout the body. Perspiration helps regulate body temperature by cooling the skin as the moisture evaporates. Sweat is composed mainly of water, but it also contains small amounts of salts and other substances. The body produces more sweat during physical activity or in hot environments, as these conditions increase the need for temperature regulation. Sweat glands play a crucial role in maintaining homeostasis and overall health.
