Note: The heat index, also known as 'feels like' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. 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. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
