Heat index values are largely significant for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions.
