Heat index values are particularly meaningful for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration.
