Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat.
