The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers.
