ELI5: What good does my nose do by leaking non-stop in the cold, then blocking up when it's goes bac to a normal temperature?

I don't know if it's cause I'm a pale ginger and can't take cold so well, but when the temperature goes below the common house temperature, my nose has a constant flow. Then blocks up when I'm in a warmer environment. It's winter here at the moment so it's a frequent annoyance.

When you breathe cold dry air the nose will release mucus to protect the sensitive spots on your lungs and some of that mucus will run out your nose which is what causes runny noses. On the other-hand your nose dries up because there is no need for this in the temperature you are used to. Hope that answers your question.
