Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
