Note when wearing a mask: Masks are good, but don’t run with them

The epidemic is still ongoing in many parts of the country. Compared with two years ago, everyone has long been accustomed to wearing masks in public areas.

It can even be said that people have gradually become dependent on masks, to the point that going out without wearing a mask feels like "running naked."

In fact, even if we put aside the prevention and control of the epidemic, wearing a mask when going out on a daily basis has many benefits.

Many respiratory infectious diseases we encounter in our daily lives, including the common cold, influenza, pneumonia, tuberculosis, etc., are mainly transmitted through droplets.

When you talk loudly, sneeze, cough or spit, some pathogens will escape into the air and be transmitted to other people through droplets.

Wearing a mask can isolate the germs and play a good role in respiratory prevention.

In addition, wearing a mask can effectively reduce contact with allergens such as pollen, dust, and animal fur, and prevent allergic diseases such as allergic rhinitis, dermatitis, and asthma.

In days when the city is surrounded by smog, wearing a mask correctly can effectively prevent pollutants from entering the respiratory tract and keep toxic and harmful substances out.

Among people who smoke, wearing an activated carbon mask can absorb and filter some of the smoke and harmful substances such as nicotine and tar, reduce the intrusion of "second-hand smoke", and reduce harm to the body to a certain extent.

In a fragrant kitchen, wearing a mask while cooking can avoid inhaling too much fumes, reduce the inhalation of carcinogens in the fumes, and reduce the probability of lung cancer.

In addition to preventing diseases, wearing a mask correctly can also prevent various harmful substances in the air from damaging the skin.

For example, car exhaust contains many harmful substances. Even if these substances do not cause us to suffer from respiratory diseases, they can cause damage to our skin if they get on our skin.

There are many hidden benefits to wearing a mask.

Are you smart enough to notice that during this epidemic, you can still walk with style even without makeup?

Once you put on a mask, no one will recognize you and you don’t have to care about other people’s eyes when you go out. It is really good news for people with social phobia.

According to everyone’s personal experience:

During the epidemic, the average appearance of people across the country has risen rapidly. Girls can go out with just a simple eyebrow makeup, and the whole street is full of beauties. It is said that some people have fallen in love with selfies during the epidemic?

Thanks to the mask, I don’t have to put on makeup in the morning to go to work, which saves time. I don’t have to remove makeup at night after get off work, which saves time. The money I used to spend on cosmetics is now all used to buy snacks. I live a happy life every day...

Of course, it should be noted that wearing masks is not very friendly to people with lung or heart diseases, as well as sports enthusiasts.

For people with cardiopulmonary diseases, wearing a mask for a long time, or wearing an N95 series mask with a strong filtering effect, may cause the wearer to have difficulty breathing. Instead, it will bring adverse consequences to the wearer, which is not worth the loss. Although this type of mask has good protection, it is not conducive to breathability.

During exercise, the body's oxygen consumption increases and a lot of oxygen needs to be inhaled. If oxygen is not inhaled in time after wearing a mask, it will cause serious hypoxia. Studies have found that when the mask is soaked, a person's breathing capacity will decrease by 10% to 20%, which means that the cardiopulmonary function can only be exerted by 60% to 70%.

In other words, wearing a high-performance mask for strenuous exercise, coupled with not replacing the mask in time after it gets wet, will greatly affect the normal function of the heart and lungs. Wearing a mask for strenuous exercise will not only cause damage to the lungs, but also to the whole body.

So, although masks are good, you cannot wear them in all occasions.
