Why do you get a blocked nose?

Answer 1

The lining in your nose is composed of erectile tissue (similar to the tissue found in sexual organs). When you have a cold (or other condition which aggravates the lining, such as hayfever), the blood vessels swell up as infection-fighting white blood cells flood to the area. This narrows the air passage in your nose and restricts the airflow as you breath.

Answer 2

This is your brain deciding which side to "carry" sinus inflammation on; note that the sides may change during the day. Omega 3, the "anti-inflammatory" oil/food, will eliminate sinus inflammation. Eventually.

Answer 3

Since each nare (plural of nare is nostrils) is its own passageway, they can be blocked separately. There may be a buildup of mucous, or sinus pressure may block the passage of air in only one nare.

Answer 4

Snot protects your nose. So when you get sick, a reaction takes place. Your nose goes into overdrive creating snot and then your nose gets blocked.

Answer 5

Cold can cause only one nostril to clog. If one is sleeping on one side the secretions of nose gravitate to one side. This is one example of why only one nostril is clogged.

Answer 6

Swollen sinuses may cause one of your nasal cavities to get blocked up. Lie on the other side and it should drain.
