Explanation:
Detailed explanation-1: -Water requirements during exercise in the heat depend on fluid loss from sweating. Sweat rate is proportional to metabolic rate and can amount to 3 to 4 liters per hour or as much as 10 liters per day. Training and heat acclimatization can increase sweat rate by 10 to 20 percent or 200 to 300 ml per hour.
Detailed explanation-2: -For instance, water is lost by the body in hot weather in sweat. This triggers the release of ADH into the blood which acts on the cells of the distal tubule and collecting duct to increase water resorption thus reducing the amount excreted.
