When running outdoors, you should choose parks or outdoor venues with few people to avoid getting together. When there are no other people around, you can run without a mask, but it is best to bring a mask in your pocket for backup, and you can wear protection in time when you pass through a crowded place. When schools carry out sports activities, teachers or school doctors should know the students' physical health in detail, and should avoid students suffering from heart disease and basic respiratory diseases from participating in strenuous sports activities. You don't need to wear a mask when you exercise at home. It is recommended to run on your own treadmill, or run in circles in the living room, which can effectively reduce contact with others.

It should be noted that some students choose to wear N95 masks for sports activities in pursuit of protective effect. Experts remind that even if students are healthy, it is best not to wear N95 masks for exercise. Because the N95 mask is very airtight, it is easy to cause poor breathing, which limits the amount of oxygen inhaled. A certain amount of exhaled gas remains in the space formed by the mouth and nose. Repeated inhalation will lead to the increase of carbon dioxide level and the decrease of oxygen content in the body, which will endanger life and health. At the same time, while wearing a mask, we must also reduce the intensity of exercise to avoid and reduce accidents.
