The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
