Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
