Note: The heat index, also known as 'apparent temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences.

Heat index values are especially vital to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
