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.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
