Heat index values hold particular importance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
