Heat index values hold particular significance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
