Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
