A salty liquid produced by the sweat glands to cool the body as the liquid evaporates from the skin.
Sweat is the fluid produced in and secreted from the sweat glands of the skin. Sweat is primarily water, but is a serous fluid containing many of the same constituents as plasma. Most importantly with respect to sports nutrition, sweat contains relatively high concentrations of electrolytes. During periods of excess sweating, fluid and electrolytes may be depleted to a great extent, requiring their replacement through the diet. Entries for hydration and electrolytes as well as sports drinks provide some detail regarding effective fluid and electrolyte replacement.
The watery fluid secreted by the sweat glands. Its principal constituents in solution are sodium chloride and urea. The secretion of sweat is a means of excreting nitrogenous waste; at the same time it has a role in controlling the temperature of the body—the evaporation of sweat from the surface of the skin has a cooling effect. Therefore an increase in body temperature causes an increase in sweating. Other factors that increase the secretion of sweat include pain, nausea, nervousness, and drugs (‘diaphoretics). Sweating may be reduced by colds, diarrhea, and certain drugs.
Sweat is the fluid produced by the skin’s sweat glands, commonly known as perspiration. It’s a clear, watery liquid containing elements like neutral fats, volatile fatty acids, small amounts of albumin and urea, lactic acid, and various salts and compounds such as sodium lactate, sodium chloride, potassium chloride, and hints of sugars and ascorbic acid. Its primary purpose is to help control the body’s temperature.
