Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
