Heat index values are primarily vital 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 response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat.

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