The epidemic has subsided and schools across the country have opened. After a long winter vacation at home, parents think they can relax. But it's really class time now, and parents still have a lot of concerns. In fact, all parents care about is lack of confidence. One is worried about watching too much news, the other is worried about the risk of students contacting too many people after school, and the other is worried that students will not wear masks when they arrive at school. In addition, recently, the news media reported that some students fainted wearing masks, and parents' worries were understandable. After all, their children are the pride of their parents. Who wouldn't like it? So, can I wear a mask when I exercise?

Due to the functional requirements of the medical masks we use, the breathing of future generations is relatively stagnant, which is equivalent to a semi-closed state. If you exercise under high load, you will need to breathe a lot of oxygen to support your body's exercise, and you will exhale more useless gas. However, the air tightness of the mask has become an obstacle, which will make the air circulation poor and cause temporary insufficient oxygen supply.

So pay attention to doing exercises: 1. Before exercise, tell students that if they feel that they can't breathe well during exercise, they can stop exercising or take off their masks to exercise. If students are physically weak, they can ask not to participate, or do some simple exercises during exercise. It depends on the amount of exercise. If it's like radio gymnastics, it doesn't matter if you wear a mask. Students can also take off their masks for exercise after expanding to a safe distance.

Be sure to wear a mask when you don't exercise, and then tell the students to keep personal hygiene. Second, protect yourself. Protecting yourself is protecting others. 1. Personal protection is the most important. When you enter the school gate, you must tell the students to wear masks, and don't take them off in crowded places, especially in class and when there are group activities in the classroom. Always wear a mask. 2. Don't get together. Be sure to tell students not to go to places where people are concentrated. Unless it is an activity organized by the school, don't participate, don't party, don't fight.
