Is Running in the Cold Bad for Your Lungs?

I knew it "Have you ever heard your mom or coach warn you not to run in the cold? "You'll freeze your lungs if you run in that frigid air," they say. You've maybe even thought it yourself: At what temperature will the cold air damage your lungs? Research shows that runners are not in danger of freezing their lungs, even in the coldest places on Earth such as the North and South Poles. Thanks to our body's brilliant design and adaptability, air reaches body temperature by the time it greets our lungs." [By Amanda McCracken - D3Multisport.com] Enjoy your run --- Kjell
