Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
