Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
