HUMAN NUTRITION

Detailed explanation-1: -As athletes exercise, the core body temperature rises. In response, the body sweats to dissipate excess heat so it doesn’t overheat. Staying hydrated replaces the water lost through sweating and is essential for thermoregulation, helping to prevent cramps, heat exhaustion and heat stroke.

Detailed explanation-2: -You need to drink more fluid than you lost while exercising because you continue to lose fluid through sweating and urination for some time after you have finished your session.
