Personally, if you can wear the mask correctly and adjust the wearing time in time, it will not be greatly affected.

We work, walk and breathe normally, but when breathing is blocked by masks, our lungs want to break away from this bondage and breathe the outdoor air happily.

So I think individuals should make the following adjustments.

? 1. You can't run with a mask on.

Yes, that's right. From the type of exercise, running, as an aerobic exercise, has mobilized the reserve capacity of breathing, accelerated breathing and increased ventilation. At this time, the oxygen demand and vital capacity of the human body increase significantly, thus exercising the cardiopulmonary function and making it stronger.

During exercise, the body's vital capacity and metabolism will increase, and the oxygen consumption will also increase sharply. For people with poor lung capacity, wearing a mask and walking for dozens of steps will make them feel difficult to breathe; After wearing a mask, breathing will be more resistant. After a long time, it is easy to cause poor breathing and dizziness. In the long run, the respiratory system will also be affected. If you don't have the ability to adapt at ordinary times, you will increase the risk of exercise, especially the risk of exercise and cardiovascular disease.

Secondly, the function of the mask is affected by the intensity of breathing, mainly to deal with the intensity of our daily breathing, to prevent harmful substances from entering the mouth and nose, and to reduce the spread of respiratory infectious diseases. Breathing and inhaling will be harder than usual when running, and the pressure generated when inhaling will be greater than usual, thus reducing the barrier function of surgical masks.

It is best to change the model of the mask frequently.

If you choose anti-smog, N95 and other masks, because of their excellent sealing performance, the air permeability is often poor. While blocking the entry of harmful substances, it also leads to the inability to discharge water vapor. If the exercise time exceeds 40 minutes, the mask will be moist and the facial temperature will decrease; Especially people who wear short-sighted glasses, when they encounter this situation, their eyes will also be foggy, which will affect their sight and have potential safety hazards.

The World Health Organization also mentioned in the way of wearing masks: "If the mask becomes wet, put on a new mask immediately." During running, breathing out the gas in your mouth and sweating after exercise have a great chance of wetting the mask. In this case, the mask loses its preventive function.

?

3. 15-30 minutes, you can take off your mask and take a route to breathe normally in an open environment with little traffic.

Wearing a mask for a long time is definitely not good, which may cause slight hypoxia. Lead to poor breathing, long-term use will reduce the adaptability of nasal mucosa to nature, easily cause allergies and cause nose sensitivity. It may also destroy the blood circulation of nasal mucosa. Lost the original physiological function of the nose. But at present, wearing a mask is responsible for the family and the society, and must be worn!

Everything should be based on facts and experiments! To understand this problem, we must first understand what is vital capacity.

About vital capacity, an encyclopedia explains it this way: vital capacity refers to the amount of gas exhaled after maximum inhalation in unlimited time, representing the maximum functional activity of the lungs in a time, and it is one of the important functional indicators reflecting the level of human growth and development. Vital capacity can show a person's cardiopulmonary function. People with large lung capacity have better oxygen supply ability.

We can simply understand it as: the maximum inspiratory volume and the maximum expiratory volume of a breath.

After understanding this, we can do an experiment without any equipment: after exhaling, close your mouth, inhale slowly and evenly through your nose and record the time. Then exhale slowly at a constant speed when the breath is full (it is best to make a sound with your mouth to ensure that you don't steal the breath, such as "O"). Because inhalation is not easy to observe, I usually observe the duration of exhalation. After all, the inspiratory volume is directly proportional to the expiratory volume.

Generally healthy adults (all around the age of 30) exhale normally for more than 40 seconds at a time, and the older they get, the younger they get. After the test, you can know your current lung capacity level.

Knowing this, let's get back to the topic, whether wearing masks for a long time will reduce our vital capacity. The answer is: yes!

After wearing a mask for a long time, you can make a lung capacity comparison with before, and the result is obvious. Then why is this?

Because when wearing a mask, the amount of air you breathe at a time is bound to be lower than usual. When the oxygen intake decreases, in order to provide enough oxygen, we will increase the breathing frequency. Because of the short breathing frequency, there is no way to use abdominal breathing, but it will gradually evolve into upper chest breathing.

It is emphasized here that there is nothing wrong with the upper chest breathing itself. This kind of breathing itself is for our emergency during exercise. But if we breathe like this for a long time, our diaphragm will not move normally. Because the diaphragm is connected with our heart and lungs, when the diaphragm can't move normally, the elastic potential energy of the heart and lungs can't be released.

We breathe a lot a day, generally about 20,000-25,000 times a day, which can easily lead to patterns in our respiratory system.

Although we will return to the state of abdominal breathing during sleep, our cardiopulmonary function will also decline day by day because the frequency of using diaphragm is greatly reduced every day.

Although the result is cruel, you still have to wear a mask. So in the end, I'll give you a solution: just practice abdominal breathing before going to bed. At first it was 10- 20 minutes a day. If it has dropped significantly, it will take 20-30 minutes a day for a week to see the obvious effect.

I won't waste your time here on how to practice abdominal breathing. I hope everyone can have a good figure [praise]

Wearing a mask for a long time will affect the vital capacity. No, please watch the following video:

Wearing a mask is mainly the need of epidemic prevention and control at present, so you must bring it. After the epidemic, all countries in the world are very calm, so they don't wear masks. How can they wear masks for a long time Of course, talking with a mask is influential. For example, raise your voice when you speak. ...

The so-called vital capacity simply refers to the total amount of gas exhaled by a person after taking a breath, which is an important reference value for human lung health. Under normal circumstances, the vital capacity of adults is between 2500 ml and 3500 ml, that of adult males is about 3500 ml, and that of females is about 2500 ml.

A study of 30 emergency nurses measured their vital capacity for 2 hours before and after wearing masks. They are wearing masks made of 16 layers of absorbent cotton. Finally, it was found that the lung capacity after wearing the mask was (2193.10281.73) ml, which was lower than that before wearing the mask (365438+). This is also an important reason why we feel suffocated and dizzy when wearing a mask.

Although some athletes wear training masks to exercise in order to train heart and lung function, in fact, unlike ordinary medical protective masks, training masks often have more breathing valves or valves specially designed to adjust air volume. Most importantly, most people who use training masks are professionals. For most people, running and skipping with a mask is not a good choice.

In addition, the study also mentioned that after nurses wore masks for 2 hours, the total number of colonies in masks also increased significantly, which increased the probability of respiratory tract infection. This is mainly because after wearing the mask continuously, the mask will be wet by breathing aerosol, and the humid environment is conducive to the growth of bacteria, especially the conditions of low oxygen and high carbon dioxide are more conducive to the growth of anaerobic bacteria.

This also reminds us that although masks are in short supply at special times, they should be replaced in time for their own health.

Doing three things well can improve lung capacity!

Everyone's vital capacity is different, and this difference is mainly related to factors such as age, gender, figure, exercise habits, respiratory muscle strength, and lung health. For example, in general, the lung capacity of the elderly and children is low, while the lung capacity of adult young people is high.

There is a saying that people usually use only one-third of their vital capacity. Then, try these methods in daily life to improve your vital capacity.

Regarding whether wearing a mask for a long time affects the lung capacity, everyone's lung capacity is different, which is mainly related to factors such as age, gender, figure, exercise habits, respiratory muscle strength and lung health. For example, in general, the lung capacity of the elderly and children is low, while the lung capacity of adult young people is high. Keep your mouth shut, adjust your breathing, and keep it even and gentle. This method can not only keep you healthy, but also help improve your lung function.
