Why does the nose water when cold?

Apart from colds, many types of diseases, viral fever or bacterial infections, or allergies also cause colds. But the case of getting a cold in the cold is a little different.

It is easy to understand that it is some kind of response to cold weather. Inside the nose is a thin mucous membrane. They have a mucous membrane and small cells called goblet cells, which secrete a substance called mucus.

When cold air enters the nose, the nasal nerves stimulate the mucous membrane. They send information about the presence of cold air to the brain, and from there the signal goes back to the membranes. The result is a runny nose or runny nose.

It is an automatic reflex action. Mucous membranes contribute to maintaining the warmth of the lining of the nose. This happens because the cold air causes discomfort in the mucous membranes.
