Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
