Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
