Nasal scab is a hard lump formed by the mixture of nasal secretions (mucus, pus, etc.). ) and dust and bacteria in the air. The scab skin formed inside the nasal cavity is not in direct contact with the outside air, so the exposed part is relatively small and difficult to clean. Over time, it will have a certain impact on respiratory function and sense of smell.

2. Appearance characteristics of nasal scab

The scabs in the nose are mostly light yellow or light gray in appearance, hard in texture, not easy to peel off, and sometimes stick to the nasal mucosa. For the long-term incurable nasal scab, there are often obvious concave and convex lines on the surface, sometimes accompanied by tingling or slight bleeding.

In addition, the size and distribution of the scab on the nose will vary from individual to individual. Generally speaking, scabs slightly larger than the size of beans are the most common, but some people may have large scabs, granules, burrs and other different forms, and sometimes there may be multiple scabs in the nasal cavity at the same time.

3. Causes of nasal scab

The scab in the nose is mainly composed of endocrine, dust and bacteria in the air. Therefore, inhaling the environment containing dust and pollution particles is also one of the main reasons for nasal scab. In addition, there are several reasons:

1. Hypersecretion of nasal mucosa: People with allergic rhinitis or sinusitis play an important role in the formation of nasal scab due to increased mucus secretion.

2. Frequent hand-blowing: Long-term hand support, nose blowing and other behaviors can also easily lead to scabbing in the nose, because this will destroy the protective layer of the nasal cavity, make the nasal cavity dry and help scabbing.

3. The air is too dry: If the air is too dry, it will evaporate the water in the nasal mucosa, leaving the nasal cavity in a dry state and easily forming nasal scabs.

4, prevention and treatment measures of nasal scab

In order to prevent the nose from scabbing, it is necessary to prevent it from the following aspects:

1. nasal hygiene: cleaning the nasal cavity regularly with physiological saline can better maintain its microecological environment, avoid the deposition of various bacteria on the nasal cavity surface, and minimize the generation of nasal scabs.

2. Air humidity regulation: nasal dryness is one of the main causes of scab, and air humidity regulation is an important method to prevent nasal scab. You can use a humidifier or drink plenty of water to increase the body's moisture, thus lubricating the nasal cavity.

3. Pay attention to daily health care: a reasonable diet, regular life and exercise will all help improve the body's immune ability, stabilize the nasal environment and reduce the occurrence of nasal scab.
