Note: The heat index, also known as 'felt air temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
