During exercise, the human body’s oxygen consumption increases and it needs to inhale a lot of oxygen. If the oxygen is not inhaled in time after wearing a mask, it will cause severe hypoxia. This behavior will not only cause damage to the human lungs, but also damage the human body. Cause damage to the whole body.

Whether it is necessary to wear a mask, it is necessary to make a scientific judgment based on the epidemic situation in each place, but it is certain that there is no need to wear an N95 mask, just a normal surgical mask.

Many disadvantages of wearing N95 masks: N95 masks are very airtight, which can lead to incomplete breathing. A certain amount of exhaled air stays in the space formed by the mouth and nose and mouth. Repeated inhalation will lead to carbon dioxide levels in the body. Increase and decrease in oxygen content.

The former leads to acid-base disorders in the body and causes respiratory acidosis; the latter makes the body's blood oxygen level drop, which may cause severe hypoxia damage to vital organs.

In addition, N95 masks significantly increase breathing resistance. Wearing such a burden during exercise is likely to cause additional damage to children's lung function. Therefore, even medical staff must strictly observe the 4-hour working time limit. Children should not wear it for a long time, and it is not recommended during exercise.

It is not recommended that children wear masks to do strenuous exercise, which may cause hypoxia. If children need to attend physical education classes, it is recommended to do them in a ventilated outdoor. Do not wear a mask when doing sports activities, try to choose sports that can keep a certain distance.
