Why does cold meet nasal obstruction

summary

Nasal congestion is the most typical symptom of a cold, which will give patients a sense of discomfort. After the cold is cured, the symptoms disappear immediately. Now let's see why the cold can cause nasal congestion.

Why does cold meet nasal obstruction

First of all: our human nose is like a room with front and back doors. There is a nasal septum in it, which divides it into two rooms on the left and right. On the side wall of each room, there are three curly turbinates. This room is called nasal cavity. The front of the nasal cavity is connected with the outside through the nostril, and the back leads to the pharynx. The pharynx is the cavity behind the nose and mouth, and it is an important road for breathing and swallowing.

Secondly: there are many nasal hairs in the nostrils. There is a layer of mucous membrane with cilia and abundant capillaries on the surface of the nasal cavity. The mucous membrane of the nasal cavity often secretes a small amount of mucus, that is, nasal mucus, to clean the inhaled air.

Finally: when you catch a cold, the nasal mucosa is inflamed, the tissues of the nose are swollen, the capillaries are dilated, and the secretions are increased. In this way, the gas in and out are obstructed, and the nose is naturally not easy to ventilate. It's like a narrow passageway full of things. Of course, it can't get in and out smoothly.
