Heat index values are highly critical to babies and toddlers. 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.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
