Note: The heat index, also known as 'real feel' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to 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.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
