Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
