Heat index values are especially vital to 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.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
