Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
