Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations.

Heat index values hold great significance 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
