Note: The heat index, also known as 'feels like' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. 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. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
