summary

The child always digs nose excrement. I don't know where he gets so much nose excrement in a day. The nose dug by hand is very red and even inflamed. We are worried about causing rhinitis. After all, we all know that rhinitis may cause a lot of symptoms, so we consulted the relevant doctors. Now let me tell you why there is so much nose excrement.

Why is nose excrement much

First: the nasal mucosa is rich in capillaries, capillaries have a strong permeability, can secrete a lot of viscous liquid, so that the nasal mucosa always keep moist. Its secretion of mucus is nasal mucus. When the air passes through the nasal cavity, the inhaled gas carries dust, particles, bacteria, etc. Most of them are absorbed by mucus to form nasal mucus, which can be discharged from nostrils.

Second: it is mainly composed of mucus. Its function is to moisten and heat the inhaled air to reduce the stimulation of dry gas to the lung. It's cold and dry in winter. You will have a deep experience. Mucus also contains lysozyme, which can kill adherent bacteria and has immune function. When the nose dries, it forms mucus.

Third: nasal mucus is due to the formation of nasal secretions coagulation. So not sick will have, but sick, nasal secretions, the formation of nasal mucus will be more There are some hair follicles at the entrance of nostrils, which usually secrete some secretion to lubricate and protect the interior of nose. When the secretion is dry, it becomes what we call nasal excrement. At this time, if you inhale unclean air (such as dust), the color of nasal excrement will be dark.

matters needing attention

Although nasal excrement will make our nose uncomfortable, we should not always dig nasal excrement with our hands. If we dig nasal excrement for a long time, it may cause rhinitis, so we should still use the correct method, such as using cotton swabs instead of fingers. This can reduce the damage to the nose.
