Heat index values are particularly relevant to 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.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
