Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
