Face to the epidemic, nobody will want to challenge their own immunity. Almost all wearing behaviors such as going to work, taking the subway, going to the supermarket, shopping in the mall, etc., wear disposable masks. After a day, it is almost accompanied by a mask. The time of wearing a mask every day is often more than 8 hours, or even a little longer, and the hazards will follow.


Wearing a mask for a long time has a more direct effect on breathing. For people with poor cardiopulmonary function, wearing a mask is undoubtedly a tortured thing. When going up stairs, buying food, and cleaning, there will be breathlessness, chest tightness, and difficulty breathing. The consequences are also more serious. If you have such problems when wearing a mask, find a place with good ventilation, remove the mask, and breathe for a while. It is better.

Wearing the mask for a long time will also destroy the skin's water-oil balance, or produce allergies. After wearing for more than 8 hours, the humidity of the disposable face mask will increase and the temperature will increase, which is very suitable for the reproduction of bacteria. The presence of a large number of bacteria, no matter whether they are harmful or not, will hinder the normal metabolism of the skin, block the pores, destroy the balance of water and oil, and cause acne and acne problems on the face. Some people with allergies may feel itching, redness, swelling and pain due to the allergy to the mask material. For a person who needs to wear a mask for a long time, it is necessary to moisturize and maintain the skin every day. At the same time, it is necessary to ensure adequate rest to avoid further affecting the endocrine and accelerating the development of acne.


If you wear a mask all the time, your facial skin will also deform, which will affect your face. The steel wire and the string on the mask have pressure on the skin, just like the underwear has been worn for a long time, there will be a mark, so is the mask. Some people wear the fabric mask for a long time and still feel a little pain in their ears. This is the reason.


One-time use of masks is limited in number and time. The cumulative use time does not exceed 8 hours, and it needs to be replaced every four hours on average. This means that everyone should prepare 2 masks a day and use them in turns. Nowadays, the supply of masks is sufficient, and the price is relatively cheap. You can not save on the use of masks. It is still very cost-effective to exchange a small amount of money for a lifetime of safety. Especially when the mask has been damaged, has been to a personnel-intensive place, or is stuck with substances such as snots and mucus, it is necessary to change it frequently to minimize the number of repeated use of disposable masks.


In summary, when the epidemic is far from over, using two masks a day can minimize the harm caused by wearing the mask for a long time.
