What does itching on the outside of the nose indicate?

It is spring now, the climate is relatively dry, and everything is reviving. Many diseases hidden in the body for many years will break out at this time. The itching outside the nose may be caused by skin infection or dust entering the nose, resulting in mild skin allergies. Regular cleaning is required, and a small amount of medication can be applied when necessary. Never scratch it with your hands.

Every day, the human body breathes through the nose, causing more and more harmful substances to accumulate in the nasal cavity. The nasal cavity, which was originally an important base for the human body to resist and prevent diseases, is likely to become a place of "filth and dirt" because a large amount of dirt accumulates on the nasal hair and nasal mucosa.

If they increase further, nasal crusts will form. These nasal crusts accumulate in the nasal cavity and can neither resist harmful substances nor help the human body. On the contrary, they are the best culture medium for the growth of microorganisms. When the air is polluted and dry, the nasal cavity's ability to secrete mucus decreases, and a large amount of dust, impurities and germs are attached to the mucus blanket at the root of the nasal cilia, causing the nasal cilia to fall over and be unable to swing normally to remove them. These long-accumulated impurities block the normal secretion of nasal mucus, and germs begin to multiply and then enter the human body. In this way, various harmful substances can easily induce colds, rhinitis and other diseases in the human body. If symptoms such as nasal congestion occur, people will not be able to breathe through the nasal cavity. At this time, people can only breathe through the mouth. Without the natural defense line, various pathogens may "go straight into" the human body and cause disease.

The areas that are picked are generally the nasal septum and nasal conchae in the front part of the nasal passage. Once the capillaries of the nasal mucosa are damaged during repeated nose picking, bleeding will occur. Not only will it fail to achieve the cleaning effect, but it will also damage the nasal mucosa and reduce the body's disease resistance. Some people are in the habit of plucking their nose hairs with their hands, which is also not advisable because it can cause local folliculitis and even lead to serious consequences because the nose is located in the "danger triangle" of the human body.

When "scabs" appear on the nose, it is best to wash it with warm water. Generally, warm water at about 30℃ is used. You can also put warm water in a nasal wash pot. After cleaning, you can cover your nose with a hot and wet towel. It can not only wash away the pathogens and dry scabs in the nasal cavity, but also exercise and enhance the protective function of the nasal mucosa and reduce the occurrence of diseases.
