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.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
