Military training is basically wearing a medical mask. In principle, wearing disposable masks should be changed every four hours. According to this standard, three or four masks should be changed every day, but I think it is necessary to adapt to local conditions and vary from person to person. Many times, everyone uses masks differently, so we need to discuss the situation.

First of all, the general military training is very close to everyone, at least half a month. The epidemic has not really passed, so it is really necessary to wear a mask. However, maybe next year, military training will change. If everyone is one meter apart, it is impossible to pile up.

In high-risk and medium-risk areas, masks need to be changed every four hours. After all, safety comes first, and the virus spreads quickly and quietly. Wearing a mask and changing it frequently is not only to protect your own safety, but also to respect others. Although the high and medium risk areas have been cleared, the safety awareness cannot be reduced.

In low-risk areas, if it is summer training, people in all corners of the school have it. Be careful and change frequently. After all, you can rest assured that there is no gap cover now. In addition, the mask is dirty after sweating on a hot day. Of course, it is also possible to change it every day. After all, everyone has a health code before entering school.

If it's winter training in low-risk areas, everyone stays in school for half a year. It is no problem to wear a mask every day without special circumstances, and it can also save some resources.

In fact, military training is not easy, and you may get dirty at the end of the day, not to mention the mask. Changing masks frequently and paying attention to hygiene are the correct ways.

Finally, I have a feeling that changing the mask often depends on personal attitude and laziness, because maybe you are just too lazy to change the mask. Maybe there is a supermarket not far away where you can buy masks, but you can't even walk, so it is necessary to change masks consciously.

Of course, changing masks frequently is not just in military training. When we face high-density people flow every day, changing masks frequently can make you, me and him safe.
