Heat index values are quite important for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
