Do we burn more calories when it is cold or hot?

Now that we are well into autumn, many of you are probably wondering how the change in temperature affects your training, and in particular your calorie expenditure.

So do we burn more calories in hot weather or cold weather? It turns out we burn more when its hot, since pumping blood toward the skin so it can turn into sweat to cool the body requires more calories than exercising in cold weather. While we do need to burn calories to keep warm when it is cold outside, vigorous exercise when it is cold burns enough calories to keep us warm at no extra calorie cost.

No matter how cold and snowy the winter may get, I won’t let it keep me inside. Like last winter, I will be out there just about every day running my miles, even if they are only “junk” miles. Having the right attitude and dressing warmly enough should allow you to engage in vigorous outdoor exercise all winter long.

  3. You’re making me feel lazy! Here it is a chilly morning in SoCal (in the 50’s) and I’m not wanting to take my dog out for a walk (I will once it gets later and warms up). I don’t know that I’d be out in knee-deep snow like you, however. More power to you!!!

    • Thank you Celeste! I hope you’re doing great and did manage to get in a little exercise somehow. The snow over here is no big deal once you get used to it. I can’t wait to see what winter has in store for us. Take care.
