Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
