Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 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.
