In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
