Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children.
