Note: The heat index, also known as 'felt air temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
