Swea

Swea, often referred to as sweating or perspiration, is a physiological process where the body releases fluid through the skin. This process is primarily driven by the eccrine glands, which are distributed across the majority of the human body. The main function of sweating is thermoregulation, helping to cool the body down when its temperature rises, such as during physical exertion or in warm environments.

When the body's core temperature increases, the nervous system signals the eccrine glands to produce sweat. As this sweat evaporates from the skin's surface, it absorbs heat, thereby lowering body temperature. Sweating can also be triggered by emotional states like stress or anxiety, or by consuming certain foods or beverages, particularly spicy ones. The composition of sweat is mainly water, with small amounts of electrolytes like sodium, potassium, and chloride, as well as urea and lactic acid. While the cooling effect is its most critical role, sweat also plays a minor part in excreting waste products. Excessive sweating, known as hyperhidrosis, can be a medical condition requiring attention.
