The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees.
