The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees.
