Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. 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.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
