The presence of direct sunlight can raise the heat index values by up to 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. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat.
