Sweating is the process by which the body releases moisture through the skin. This occurs primarily through sweat glands, which are found all over the body. When the body temperature rises due to heat, exercise, or stress, the brain signals these glands to produce sweat. As the sweat evaporates from the skin, it helps cool the body down. Sweat is mostly composed of water, but it also contains small amounts of salts and other substances. The amount of sweat produced can vary based on factors such as temperature, humidity, and individual fitness levels. Sweating is a natural and essential mechanism for regulating body temperature.
