Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth.

When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
