Heat index values are particularly meaningful for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
