Heat index values are particularly important for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down.

When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
