An athlete sweats when he exerts. Working muscles produce heat as one of the by-products of energy production. Sweating is one way to “keep the engine cool” and make sure the horse’s temperature stays within healthy limits. In order to restore fluid lost through sweating, the horse must increase his water intake to combat hydration – loss of fluids and minerals.
