Heat index values are extremely significant for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling.
