In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
