Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
