Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
