Why does it sometimes sting to breathe in cold air?



  1. 0 Votes

    Some people experience a burning sensation in their lungs when they inhale cold air, particularly through their mouths. This is because the mucous in the glands has to work extra hard to heat and moisten the cold, dry air. When you exercise, this sensation is especially strong because you are breathing in more air, faster. The body is higly adaptable and cold air does not damage your lungs under normal conditions. Oh, and don’t worry – you’re lungs aren’t actually going to freeze.
