Heat index values hold particular significance for children. 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, thanks to perspiration, acts as a natural air conditioner for the human body.
