Many people find that their nose itches and they can't help but take it out, but this small action may also endanger life. If you want to clean your nostrils, you should use the right method instead of using your hands.
If the nose itches, it will subconsciously pull out. This small action not only affects the image but also may cause infection and even endanger life.
The nasal hair in the nostril is the first barrier of the respiratory tract, which has a filtering effect on the inhaled air. Often digging the nostril by hand will cause the nasal hair to fall off, making the external unclean air directly stimulate the nasal mucosa, and the nose is more prone to pruritus, especially those with the allergic constitution will aggravate allergic rhinitis; The skin of the nostril often suffers from mechanical friction, which is easy to damage the epithelium. Besides, the stimulation of secretions will lead to inflammation of nasal vestibule, dryness and pain of nostril skin, and the formation of swelling and furuncle; the septum of the nose has rich blood vessels, which is a potential bleeding area, and slight trauma will cause epistaxis; More seriously, the human nasal vein and intracranial vein are connected, there is no valve in the middle, that is to say, there is no barrier in the middle. When digging the nostril, the bacteria in the hands enter the nasal cavity, which can easily cause nasal infection, such as nasal vestibulitis, nasal vestibular furuncle, cellulitis, etc. The pathogenic bacteria of nasal infection can enter the brain through the vein, causing fatal intracranial infection and life-threatening.
So, in the end, how should we treat the nostrils, the "portal" of the human body? The first thing to do is to get rid of the bad habit of nose-picking. If the nasal cavity often has secretions, you can clean the nostrils once every morning and evening, preferably with flowing water, which can not only prevent the nostrils from drying and itching but also protect the nose. After washing the face, wash the upper part of the nostril with the pulp of the index finger, and clean the lower part of the nostril with the finger pulp of the ring finger. When there are nasal mucus and nasal excrement, it should be dipped in water or light saltwater with a soft cotton swab, and then gently probe into the nasal cavity to remove it.
