Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
