Heat index values hold great significance to children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat.

Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
