Does the outside temperature have any effect on the number of calories burned during exercise?
If I walked a mile in the winter when it was 40 degrees, in the spring when it was 70 degrees, and in the summer when it was 90 degrees, which instance would burn the most calories?
Here’s an extremely unscientific study. I’m sure someone will be along to beat me down presently:
Assuming that you’re appropriately dressed for the weather, I think you will burn the same amount of calories in each case. If you’re dressed in shorts and a t-shirt I think you’ll burn the most calories in the winter, as you will also be shivering.
That said, for more intensive types of exercise, I’ve noticed that I get to exhaustion much more quickly when it’s 90 out than when it’s 70. I assume that I’d burn more calories and fatigue quicker in 40* weather than in 90 because I’d need more energy needed to keep my muscles at the temperature to move as necessary.
Anyone with actual facts?
