Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers.
