In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
