Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
