Heat index values are extremely vital to 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.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down.

Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
