Don't know what to believe when it comes to winter running? Here are the cold facts:

Myth: You'll freeze your lungs.
Fact: There's no evidence that exercising in cold weather, even in extreme cold, will hurt your lungs. If the cold air hurts your throat, breathe through a bandana or a polypropylene facemask.

Myth: You'll burn more calories when you run in the cold.
Fact: When you run continuously, you burn roughly 100 to 120 calories per mile. The air temperature doesn't significantly change this.

Myth: You don't have to drink as much when it's cold.
Fact: Most people sweat about as much during winter runs as they do during summer runs, but many runners don't recognize dehydration as easily during the winter. When in doubt, drink.

Myth: We're meant to hibernate during cold weather, not run.
Fact: Just take a trip to the Twin Cities in February and see how many people are running outside, enjoying the subzero temperatures. With the right clothing and a positive attitude, you can adapt to just about any type of weather.
