Nostril concept

Nostrils, nasal passages that communicate with the outside.

There is a thin and tender mucous membrane in the nostril (nasal cavity). Its former head has black hair, which can block the dust and impurities in the air. There are many capillaries in it, which can make the inhaled air close to body temperature and secrete mucus. (Ie, snot) to make the air moist and stick to the dust bacteria in the air. So the nasal cavity is the first line of defense of the respiratory system. Digging the nostrils by hand will damage the function of this "line of defense"; nails can easily cut through the nasal mucosa, and it is easy for bacteria attached to the nails to invade the nasal mucosa, causing inflammation and bleeding, and even purulence. The veins in the nasal cavity communicate, and the area around the nose is medically called the "dangerous triangle." If bacteria in the nasal cavity invade the cranial cavity and cause infection and purulence, it will be life-threatening, so do not let your child dig the nostrils.

Nostril is harmful to health

First, digging the nostrils can cause various diseases

Poor nostril habits often lead to atrophic rhinitis. Due to atrophy of the nasal mucosa and reduction of secretions, the defense ability of the nasal cavity is reduced or lost, which results in a series of respiratory diseases, such as chronic pharyngitis, chronic bronchitis, sinusitis, and even secondary diseases such as pulmonary infection.

There is a thin layer of mucous membrane in the nasal cavity of the human body, and there are very rich capillaries. If the nostrils are dug frequently, the capillaries will be damaged and bleeding will occur.

Second, the nasal cavity is a "dangerous triangle"

There are many nasal hairs in the front nasal atrium, forming a "protective forest", blocking the dust and bacteria mixed in the air from entering the lungs. When digging the nostril, the nose hair is often cut off, making the nasal cavity a portal for microbial invasion, and it can also cause anterior nasal infection. In severe cases, it can cause intracranial suppurative infection. The nose is regarded as the central area, and this part is called the "dangerous triangle area". You must not act lightly.

Third, why do people like to dig nostrils

Why do people like to dig nostrils? The reason for this problem is; the amount of oxygen needed to ensure that the upper airway is not blocked by dirt and to maintain human life. The upper respiratory tract of the human body must be kept in an unobstructed state, because too much secretion in the nasal cavity and dirt attached to the nose hair can block the nostrils and cause insufficient airflow, so people often inadvertently clean the nostrils with their hands. The garbage is used to ensure that the oxygen content in the space gas has sufficient oxidative effect on the body, so people often dig nostrils is also a human instinct in evolution.

Nostril two nostrils

The nose plays a very important role in the oxygen supply process. The nose is an important channel for outside oxygen to enter the human body. At the same time, it is also responsible for exhaling carbon dioxide from the body. We can think of the nose as a whole organ, but because most of the nose's functions are done in a stereo system, we need two nostrils.

As we all know, we have two left and right lungs, but few people may know that each side of the lungs is controlled by its corresponding nostril on the same side.

Therefore, if one nostril is blocked, the lungs on both sides will compete, making people feel uncomfortable and not breathing. Not only that, the experts believe that the two nostrils can make breathing exercise more effective, and then promote the entire body's metabolism. Ventilation with two nostrils allows each nostril to take a short break. If you use only one nostril to ventilate, you will feel tired for 3 hours.

The physical structure of the two nostrils helps sleep. If you stay in a sleeping position for more than 8 hours of sleep, the nostril on one side is usually occluded due to the change of gravity compared with standing position.

Therefore, we can sleep more relaxed with two nostrils for ventilation. Due to the reduced need for oxygen during sleep, even if one nostril is temporarily blocked, only the other breath will not cause poor breathing.
