Advantages and disadvantages of wearing a mask

Advantages and disadvantages of wearing a mask. In real life, many people have the habit of wearing masks. In fact, wearing a mask is also a good habit now, but wearing a mask also has certain disadvantages. Share with you the advantages and disadvantages of wearing a mask.

Advantages and disadvantages of wearing a mask 1 advantages

1. Prevention of infectious diseases: various infectious diseases spread wildly in autumn and winter, among which respiratory diseases are the most. Wearing a mask can effectively prevent bacterial viruses from entering the respiratory tract, which has a certain effect on preventing respiratory infectious diseases.

2. Keep warm: As the weather gets colder and colder, people always feel cold on their faces when they go out, and masks have a certain effect of keeping out the cold and keeping warm.

3, anti-smog: As we all know, with air pollution, the current smog situation is very serious, and the harmful substances in the smog are very harmful to our health, so wearing a mask can also prevent smog.

disadvantaged

1, not conducive to skin health: masks are actually very easy to be contaminated by bacteria, so if you wear masks often, some skin infections may occur, which is not conducive to skin health.

2, it will lead to slight hypoxia: some masks have poor air permeability, and wearing masks for a long time will easily affect people's absorption of oxygen, which will lead to slight hypoxia.

What are the precautions when wearing a mask?

1, masks should not be worn for a long time. Wearing a mask for a long time will affect people's breathing, affect the alternation of oxygen and carbon dioxide, and may also lead to some diseases, which are not conducive to health.

2. Pay attention to cleaning after wearing the mask, because the mask is easily contaminated by bacteria. If you need to wear it repeatedly, it is best to wash it often and disinfect it in the sun.

Advantages and disadvantages of wearing a mask 2 advantages of wearing a mask when running in winter

There is actually no corresponding answer to this question. It's best to decide according to the situation. If the air pollution is too serious, it is still necessary to bring it, but many people will feel particularly uncomfortable with running and often disrupt the normal rhythm. In this case, not wearing it is the best choice.

Because in a strict sense, this behavior has certain advantages and disadvantages. Give you a brief talk. First of all, talk about the benefits of wearing a mask.

Wearing a mask in cold winter can effectively prevent cold air from entering the nose and mouth, and can further avoid the irritation of cold air to the nasal cavity and respiratory tract. And there are a lot of allergens in the air. Masks can keep them out and protect your health as much as possible.

Secondly, most of the face will be covered by masks, which can also block the cold wind and prevent skin frostbite to some extent. Many people always run in the morning, when the smog is the most serious;

Because the sun has just risen, the smog has not completely dispersed. At this time, if you wear a mask, you can effectively prevent pollutants from entering our body and form a layer of protection on the body surface. Winter is the season of high incidence of respiratory diseases. If you don't wear a mask when running, you are particularly prone to get infected with some bacteria and get sick.

abuse

In the process of exercise, the body's vital capacity and metabolism will increase, and the oxygen consumption will also increase sharply at this time. For those with poor lung capacity, even if they don't wear masks, they will find it difficult to breathe. If they wear it, their breathing will be greatly hindered. After a long time, it is easy to cause poor breathing and dizziness. In the long run, the respiratory system will also be affected to some extent.

Secondly, if you choose an anti-fog mask, the sealing performance is particularly good, but the air permeability is often poor. Although it can prevent harmful substances from entering, at the same time, water vapor cannot be discharged;

If you exercise for a long time, the mask will be wet on your face in the later period, which will not only be particularly uncomfortable, but also reduce the temperature of your face. For those who are nearsighted, if this happens, the glasses are prone to fogging, which will affect the line of sight, and there are also great security risks.

Although wearing a mask can effectively block our contact with cold air and prevent respiratory diseases, if this continues for a long time, the body's immunity will gradually decline. As long as you don't wear it one day, you may catch a cold. I hope everyone will pay attention.

The above is an analysis of the advantages and disadvantages of wearing a mask in winter running. I hope it will be helpful to all your friends. In fact, if the outdoor environment is particularly bad, we can exercise indoors. Going up and down stairs can also replace running, and it can also have a good exercise effect on the body, because even wearing a mask can't isolate all pollutants and bacteria, and it will have a great impact on breathing. Really not recommended.

If you really want to insist on outdoor sports, it is recommended to choose a sports mask. Its wrapping and air permeability are much better than ordinary ones, and will not affect our sports rhythm.

Advantages and disadvantages of wearing a mask 3 The role of ordinary masks

Masks have a certain filtering effect on the air entering the lungs. Wearing a mask has a very good effect when respiratory infectious diseases are prevalent and when working in polluted environments such as dust.

Duration of use

From the physiological structure of human body, because the blood circulation of nasal mucosa is very strong, the passage in nasal cavity is very tortuous, and nasal hair constitutes a "barrier" for filtration. When air is inhaled into the nostrils, the airflow forms a vortex in the tortuous channel, which warms the airflow inhaled into the nasal cavity. Experiments show that when cold air at minus 7℃ is inhaled into the lungs through the nasal cavity, its airflow has been heated to 28.8℃, which is very close to the temperature of the human body.

If you wear a mask for a long time, it will make the nasal mucosa fragile and lose the original physiological function of the nasal cavity, so you can't wear a mask for a long time. Masks can only be worn in special circumstances, such as crowded places with poor ventilation. Of course, you need to wear a mask when walking in the wild, in order to prevent wind, sand and cold, or to move in an air-polluted environment, but the time should not be too long. In addition, in the flu season, you should wear a mask when you go to public places where there may be a lot of pathogenic bacteria. Wearing a mask is only one of the ways to prevent respiratory infectious diseases, and the most important thing is to maintain good living habits.

Cleaning and maintenance

The outer layer of the mask often accumulates a lot of dirt such as dust and bacteria in the outside air, while the inner layer blocks exhaled bacteria and saliva. Therefore, the two sides can't be used alternately, otherwise the polluted dirt on the outer layer will be sucked into the human body directly and become the source of infection. When the mask is not in use, it should be folded into a clean envelope, and the side near the nose and mouth should be folded inward. Never put it in your pocket or around your neck.

If the mask is wetted by exhaled hot air or saliva, its function of blocking germs will be greatly reduced. Therefore, it is best to prepare more masks for replacement at ordinary times and replace them once a day. When washing, you should first scald it with boiling water for 5 minutes.

Masks should be cleaned and disinfected every day, and both gauze masks and air filter masks can be heated and disinfected. The specific approach is:

1, cleaning. First, gently rub the gauze mask with warm water and soap. The bowl-shaped mask can be lightly brushed with a soft brush dipped in detergent, and then washed with clear water. Please be careful not to rub hard, because if the gap between the warp and weft of the gauze is too large, it will lose its anti-foaming effect.

2, disinfection. Soak the cleaned mask in 2% peracetic acid solution for 30 minutes or boil it in boiling water for 20 minutes or steam it in a steamer for 15 minutes, and then dry it for later use. This method is suitable for gauze masks and bowl masks.

Step 3 check. Before using it again, carefully check whether the mask and mask are still in good condition. For gauze masks and masks, the light transmission inspection method can be adopted, that is, to see if there is obvious light spot before taking the lamp, and whether the light transmittance of the middle part and the edge part is consistent. If in doubt, you should replace them with new ones.

In any case, masks and masks need to be updated after 3 to 7 times of cleaning, and masks with particularly good quality can be cleaned 10 times. Activated carbon adsorption masks should be replaced regularly. If the activated carbon interlayer cannot be replaced, it should be replaced after 7 to 14 days. This mask cannot be reused after cleaning.
