Heat index values are extremely significant for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates.

Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
