Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating.
