When the nose itches, it will subconsciously pull it out. This small action not only affects the image, but also may cause infection and even endanger life.
The nasal hair in the nostrils is the first barrier of the respiratory tract, which has a filtering effect on the inhaled air. Picking the nostrils often by hand will cause the nasal hair to fall off, so that the unclean air outside will directly stimulate the nasal mucosa, and the nose is more prone to pruritus, especially for people with allergic constitution, which will aggravate allergic rhinitis; The nostril skin is often subject to mechanical friction, which is easy to damage the epithelium. In addition, the stimulation of secretions will lead to inflammation of the nasal vestibule, dryness and pain of the nostril skin, forming redness, swelling and boils; There are abundant blood vessels in the nasal septum, which is a potential bleeding area. Slight trauma will cause epistaxis; What is more serious is that the human nasal vein is connected with the intracranial vein, and there is no valve in the middle, that is to say, there is no barrier in the middle. When picking the nostrils, the bacteria in the hands enter the nasal cavity, which is easy to cause nasal infection, such as nasal vestibulitis, nasal vestibule furuncle and cellulitis. Pathogenic bacteria in nasal infection foci can enter the intracranial through veins, causing fatal intracranial infection and endangering life.
So, how should we treat the nostrils, the “gateway” of the human body? The first thing to do is to give up the bad habit of picking your nose. If there are often secretions in the nasal cavity, wash the nostrils in the morning and evening every day, preferably with flowing water, which can not only prevent the nostrils from drying and itching, but also protect the nose. After washing the face, clean the upper part of the nostril with the pulp of the index finger and the lower part with the pulp of the ring finger. If there is nasal mucus or nasal excrement, dip a soft cotton swab into clear water or light saline and gently probe it into the nasal cavity to roll it away.
