Heat index values hold particular significance for children. Kids are usually in more danger than grown-ups as they tend to sweat less.

When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
