Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children.
