An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers.
