Heat index values are extremely vital to babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation.

Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
