Can nose hair prevent haze? Nose hair has this magical effect
4hw.com.cn: talking about nose hair, many people think it is very dirty. In fact, nose hair itself is not dirty. Moreover, its function is more like the filter element of the air purifier, which helps us filter the dust and invisible bacterial sundries in the air. When the haze day is coming, many little friends are curious. Can nose hair filter the haze? Let's have a look.
1. Block the dust and bacteria in the air, so that the human body can inhale the filtered clean air.
2. Intranasal cilia can also make some bacteria enter the stomach with mucus and kill bacteria with gastric acid. Nasal mucosa can also secrete immunoglobulin A to encircle and annihilate invading bacteria.
3. Nasal hair can maintain the temperature of nasal mucosa, prevent external cold air from being directly inhaled into the trachea, and also keep the nasal mucosa moist. It can prevent dry or atrophic rhinitis and epistaxis.
4. Nose hair can protect the olfactory nerve from damage, so that the nose can smell all kinds of odors, transmit the smell of food to the brain and enhance appetite.
5. When large foreign bodies, such as insects, enter the nasal cavity, the nasal hair not only blocks them, but also transmits information to the nervous system, causing sneezing and removing them.
Simply put, it is located at the gate of the respiratory tract and grows nasal hair on the nasal mucosa. It is located in the front position. It is like a sentry at the respiratory gate. It is responsible for preventing dust and bacteria from entering the body with the breath. Any tiny dust entering the nasal cavity can stick so that it cannot invade. At the same time, mucus plays a role. The dust and bacteria blocked by nasal hair stick to the mucus secreted by nasal mucosa to form snot and be discharged from the body. Larger foreign bodies, such as insects and grass scraps, enter the nasal cavity, transmit information through the nervous system, cause sneezing and remove them.
It can be seen from the above that nasal hair plays an extraordinary role. How about its effect of resisting haze?
First, it is difficult for nose hair to stop small particles:
'haze' as its name implies is fog and haze. Haze weather is an air pollution state. Haze is a general expression of excessive content of various suspended particles in the atmosphere. In particular, PM2.5 (particles with aerodynamic equivalent diameter less than or equal to 2.5 microns) is considered to be the 'culprit' of haze weather.
The nasal hair can block 95% of particles larger than 10 microns, but it is difficult to care for particles smaller than 2.5 microns.
Second, 'hiding filth' affects the original regulation ability:
When the nasal cavity is polluted and dry, the movement of nasal cilia will be hindered, and a large amount of dirt, bacteria and viruses will be deposited on the nasal mucosa and nasal cilia, which will inhibit the original function, which will more easily lead to rhinitis, sinusitis and other inflammatory and allergic diseases. If patients repeatedly ignore nasal cleaning, it will even bring more diseases, such as viral influenza, upper respiratory tract infection, pneumonia and so on.
From the above two points, it can be seen that under normal circumstances, the body's own 'defense system' plays an important role, and in harsh environments, it will also 'system paralysis'.
Therefore, relevant experts suggest that people do the following:
1. At ordinary times, we should pay attention to maintaining appropriate indoor temperature and humidity as far as possible to give the nasal cavity a stable environment for its function;
2. Try to breathe with your nose to keep your mouth moist and reduce the irritation of pollutants to your throat;
3. Don't pick your nose with your hands, don't pull your nose hair, and avoid damaging the normal function of the nasal cavity;
4. Be kind to your nose: you can cover your mouth and nose with a warm towel after getting up and breathe for a few minutes. You can also wash your nose directly with cold water, but you don't have to be diligent and fast. Especially for patients with rhinitis, too much clarity will destroy the pH of the nasal cavity, and it's best to use normal saline.
To sum up, 'long and thick nose hair' can not add points to blocking haze, nor can it stand out in evolution. No matter how strong everyone's nose hair is, we should pay attention to entering the room from the outside, wash our face, gargle and clean our nose in time, remove the pollution residues attached to our body, open windows for ventilation at ordinary times, and try to avoid the peak period of haze in the morning and evening, Be careful not to drive too long.
Finally, pay attention, do not pull out the nose hair, do not pull out the nose hair, do not pull out the nose hair! Don't dig your nose, don't dig your nose, don't dig your nose! Repeat three!
