Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
