Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
