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.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
