The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
