Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children.
