Can nose hair prevent haze

4hw.org: when it comes to nasal hair, it's a topic that people can't avoid. Many people think it's dirty and disgusting. In fact, it's not dirty. It's like the filter element of the air purifier, which helps us to filter the dust and invisible bacteria and sundries in the air. The haze is coming. Many people must have thought about whether nose hair can filter haze. Let's take a look at it together!

1. Block the dust, bacteria, etc. in the air, so that the human body can inhale the filtered clean air.

2. Nasal cilia can also make some bacteria enter the stomach with mucus and kill bacteria with gastric acid. The nasal mucosa can also secrete immunoglobulin A to wipe out the invading bacteria.

3. The nasal hair can keep the temperature of the nasal mucosa, prevent the cold air from directly inhaling into the trachea, keep the nasal mucosa moist, and prevent dry or atrophic rhinitis and epistaxis.

4. The nose hair can protect the olfactory nerve from being damaged, enable the nose to smell all kinds of smells, and transmit the flavor of food to the brain to increase appetite.

5. When large foreign bodies, such as small insects, enter the nasal cavity, the hair of the nose not only blocks them, but also transmits information to the nervous system, causing sneezing and removing them.

In short, it is located at the gate of respiratory tract, where the hair on the nasal mucosa grows. It is located at the front position, like the sentry of the respiratory gate, which is responsible for the mission of preventing dust and bacteria from entering the body with the breath. Any tiny dust that enters the nose can stick to prevent it from invading. At the same time, mucus plays a role. The dust and bacteria blocked by the hair of the nose adhere to the mucus secreted by the mucous membrane of the nasal cavity, forming the snot and being discharged from the body. The larger foreign bodies, such as insects and grass scraps, enter the nasal cavity and transmit information through the nervous system, causing sneezing and clearing them out.

It can be seen from the above that the function of nose hair is extraordinary, so how does it resist haze?

First, it is difficult for nose hair to stop small particles:

"Haze" as its name implies is fog and haze. Haze weather is a state of air pollution. Haze is a general expression of the content of various suspended particles in the atmosphere exceeding the standard, especially PM2.5 (particles with equivalent aerodynamic diameter less than or equal to 2.5 microns) is considered to be the 'culprit' of haze weather.

For particles larger than 10 microns, nose hair can block 95%, but for particles smaller than 2.5 microns, it is difficult to guard.

Second, the ability to "hide dirt" affects the original regulation:

When the nasal cavity is polluted and dry, the movement of the nasal cilia will be blocked, and a large number of dirt, bacteria and viruses will be deposited on the nasal mucosa and the nasal cilia, which will inhibit the original function, thus more likely to cause inflammation and allergic diseases such as rhinitis and sinusitis. If the patient repeatedly ignores nasal cleaning, it will even bring more diseases, such as viral influenza, upper respiratory tract infection, pneumonia and so on.

It can be seen from the above two points that under normal circumstances, the 'defense system' of the human body plays an important role, and under adverse circumstances, it will also 'system paralysis'.

Therefore, relevant experts suggest the following:

1. In general, it is necessary to keep appropriate indoor temperature and humidity as much as possible, so as to provide a stable environment for the nasal cavity to play its functions;

2. Try to breathe through the nose, which is conducive to keeping the mouth moist and reducing the irritation of pollutants on the throat;

3. Don't pick the nose with your hands, don't pull the nose hair, and avoid damaging the normal function of the nose;

4. Treat the nose well: after getting up, you can gently cover your mouth and nose with a warm towel to breathe for several minutes, or you can directly clean your nose with cold water, but you don't need to be more diligent, especially for rhinitis patients, too much clarity will damage the pH of the nasal cavity, and it's better to use physiological salt water.

To sum up, 'long and thick nose hair' does not add points to prevent haze, nor does it stand out in evolution. No matter how 'robust' everyone's nose hair is, we should pay attention to entering the room from the outside, wash face, rinse mouth, clean nose in time, remove the attached pollution residues, open windows and ventilate at ordinary times to avoid the peak period of haze in the morning and evening, and pay attention not to Drive too long.

Finally, pay attention to never pluck the nose hair, never pluck the nose hair, never pluck the nose hair! Never dig the nostril, never dig the nostril, never dig the nostril! Repeat three!
