Heat index values hold particular importance for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
