If you are just starting out running or exercise try avoid extremes of temperatures. If you are at a place that goes below freezing 0 degrees Celsius or 32 Fahrenheit in the winter consider joining a gym for the winter and use a treadmill.
This is not problem for me, however I have the opposite problem it often gets about 40 degrees Celsius or 110 Fahrenheit. I try and run early mornings or in the cool of the evenings or even at night if you live in a safe neighbourhood.
Try and avoid traffic if you can because breathing in all those traffic fumes cannot be good for you, if you are trying to improve your fitness. If you are training at night wear bright clothing or even reflective clothing.
