My Nose Run When It is Cold Outside
Why Does My Nose run when it is Cold Outside?
The nose is a composite organ, entailed not only to help us smell wonderful (or not so wonderful) smells but also to act as a change device for incoming air. It might be surprising to learn that your nose secretes, when you’re healthy about 32 ounces (.94 liters) of secretion every day. These secretions help to humidify, warm up, and filter entrance air, in conjunction with the small hairs in the nose. Underneath the glands that secrete mucus, you have huge amounts of tiny blood vessels.
There’s also the issue as observed above of pattern mucus and secretion production. At room temperature, your nose is already producing four cups of fluid and mucus a day. Only so much of it can fall to the back of the throat and be believed. When mucus and secretion production increases to warm the air, you will see the nose run when it is cold because you have excess secretions. In other words, some of it has to drip out the front of the nose because you have an extra supply. When you get into a warmer room, a few moments later you won’t notice your nose continuing to run because your nose has warmed up and the blood vessels become more constricted.
