Heat index values are especially crucial for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities.

The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air.
