- QUESTION: It gets very cold in my area, but I still continue to get out and
- jog. I dress warmly, in layers, with good mittens to protect my hands.
- Still, my wife thinks I am taking a chance of getting frostbite of the lungs,
- especially when temperatures drop to near 0 degrees. Any chance she could be
- right? How cold would it have to get before this injury could occur?

- ANSWER: Since there is no such injury as frost bitten lungs, I can't quote a
- temperature for you. The body is so well constructed, that even when
- breathing in cold air of temperatures that can be way below 0 degrees, it is
- warmed and moistened before it gets very far into the bronchial tree that
- carries air to the lung tissue. Despite the fact that breathing in very cold
- air can cause discomfort, even pain, no damage is done. You can improve
- things a bit by wearing a covering over the nose and mouth, like a scarf or
- mask, that helps warm the air and reduce the pain.
- However, people with angina and asthma do run increased risks when
- exercising in the cold, for the combination of exercise and cold air can
- trigger an attack, and so they must be more cautious about outdoor exercise
- when temperatures drop.
