Note: The heat index, also known as 'felt air temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity.

Heat index values are especially crucial for babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
