Heat index values are extremely significant for children. 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.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
