Heat index values are extremely significant for babies and toddlers. 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down.
