The nasal mucosa is damaged, so it becomes a nasal congestion.

The cold is an infectious disease caused by a filtering virus, and its main lesion site is in the upper respiratory tract, so it is also called "upper respiratory tract infection" in medicine. The so-called upper respiratory tract includes the nose, throat, and trachea, which is the only way for gas to enter and exit the human body.

Our human nose is like a room with a door at the front and back, and there is a nasal septum in the middle that divides it into two rooms, left and right, and on the side wall of each room hang three curly turbinates, this house is called the nasal cavity. The front of the nasal cavity is connected to the outside world through the nostrils, and the back part leads to the pharynx. The pharynx is a cavity behind the nose and mouth, and it is a communication artery for breathing and swallowing.

There are many nasal hairs growing in the nostrils, and there is a mucous membrane with cilia and extremely rich capillaries on the surface of the nasal cavity, and the nasal mucosa often secretes a small amount of mucus, or nasal mucus, to clean the inhaled air.

When you have a cold, the nasal mucosa becomes inflamed, the tissues swell, the capillaries dilate, and the secretions increase, which hinders the flow of gases in and out, and the nose is naturally not easy to ventilate. It's like a passage that wasn't wide and it's full of things, and of course the entry and exit can't be smooth.
