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 a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
