Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
