Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
