Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.

Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children.
