  • Haha, you got me wondering. So I googled it :D

    "When you're outside on a cold day, your nose tries its best to warm up the cold air you breathe before sending it to the lungs. Tiny blood vessels inside your nostrils open wider (dilate), helping to warm up that air. But that extra blood flow leads to more mucus production."

  • The above is correct, because think of your nose as your little personal humidifier. It acts like this and also filters. It's such a handy little device!

  • God's amusement is my guess after the factual statement.

    You know, outside, have on mittens and your nose starts to run.

  • Always wondered, never knew. Good ?. My nose always runs though (allergies) and seems to run more when it is cold, but it doesnt really phase me I am so used to it.

  • I felt guilty about my joke above, so I did google the question and found this.

    "Underneath the glands that secrete mucus, you have huge amounts of tiny blood vessels, which help supply these glands. In cold weather, these blood vessels dilate or grow larger. This means you have more blood supply to your nose, which in part protects your nose from the cold, but it also means your nose will begin producing greater amounts of mucus and liquid. "
