the nose is the gateway to the human respiratory tract. The nasal cavity is rich in capillaries and secretes viscous liquid. They play the role of heating cold air and wetting dry air. The crisscross nasal hair is a protective barrier and has the function of filtering dust and impurities in the inhaled air. Whether the nose function is normal or not is directly related to the health of respiratory tract.
1. Picking nostrils can lead to various diseases.
bad nostril digging habits often lead to atrophic rhinitis. Due to the atrophy of nasal mucosa and the decrease of secretion, the defense ability of nasal cavity decreases or loses, resulting in a series of respiratory diseases, such as chronic pharyngitis, chronic tracheitis, sinusitis, and even secondary pulmonary infection.
there is a thin mucous membrane in the nasal cavity of human body, and there are abundant capillaries below. If you often dig your nostrils, the capillaries will be damaged and bleed.
2. The nasal cavity is a “dangerous triangle”.
there are many nasal hairs in the anterior nasal vestibule, forming a “protective forest” to block the mixed dust and bacteria in the air from entering the lungs. Picking the nostril often removes the nasal hair, making the nasal cavity a gateway for microbial invasion. At the same time, it can also cause anterior nasal infection. In severe cases, it can cause intracranial suppurative infection. Because the veins in the nasal cavity are connected with the veins in the skull cavity, the nose is regarded as the central area in medicine. This part is called the “dangerous triangle”, which must not be taken lightly.
finally, I advise you here:
you must not form the habit of picking your nose. In addition, pulling out nose hair can cause the same harm as digging nostrils. People who have the habit of digging their nostrils and plucking their nose hair should get rid of this bad habit.
