Can you wear a mask during exercise? Is it safe not to wear masks?
Don’t lose weight in May, June is sad.
At the moment when the risk of the epidemic is reduced and people begin to resume their normal work and life, more and more people regain their enthusiasm for sports.
However, the recent two sudden death events of students suspected of wearing masks caused people who like sports to fall into a dilemma-people who do not wear masks worry about risks, wearing masks also seems to be risky.
Then, can you wear a mask during exercise? Is it safe not to wear masks? Sike will give professional answers to this.
The two tragedies are thought-provoking
Xu Zhimin, deputy chief physician of cardiovascular Internal Medicine of Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, said: “The sudden death of children is generally related to the underlying diseases of their own bodies, the specific cause of sudden death needs the final autopsy results to be determined.”
But what can be seen is that in just one week, similar tragedies occurred successively in many places seem to be related to children wearing masks when running.
In addition to grief, it is even more thought-provoking. Do you need to wear a mask when exercising?
Everyone has experience. When running and other strenuous exercises, the human body’s oxygen consumption increases, so it needs to breathe and consume more oxygen.
Under normal circumstances, wearing a mask can protect us from viruses.
But wearing a mask for strenuous exercise is another matter. Because masks are bound to hinder oxygen inhalation and may cause severe hypoxia.
Cheng Kai, the deputy chief physician of rehabilitation medicine department of Nanjing First Hospital, said: “In the process of exercise, oxygen consumption will be 9-10 times higher than normal (under circumstances).”
In addition, if exercise causes the mask to be soaked by sweat, the danger will be even greater. Experts say that after the mask is soaked, people’s breathing capacity will decrease by 10% to 20%.
Therefore, even healthy people may cause imbalance of body compensation and increase the burden on lungs and heart.
Therefore, in general, the expert’s advice is not to recommend ordinary people to wear masks for strenuous exercise.
“In the long run, it will not only fail to achieve the purpose of fitness, but also increase the burden of cardiopulmonary function.” Tang Yongjun, a professor of respiratory medicine in Xiangya Hospital of Center-South University, said.
Ordinary people will face risks when wearing masks, not to mention minor students with immature heart and lung function.
Especially N95 masks, even medical staff should strictly abide by the 4-hour working time limit, while children should not wear them for a long time, and they are not recommended during exercise.
Sun HHH, associate professor of cardiac surgery at Beijing Fuwai Hospital, said in his WeChat article: “Schools that have just resumed classes should not hold fierce competitive sports competitions for the time being, resume children’s physical exercise step by step. Do not wear masks during intense sports, especially N95 masks. ”
Some cardiovascular experts also said that students are not recommended to wear masks for exercise when teachers and students keep a proper safe distance.
Then the problem comes. Since children are not suitable to wear masks for PE classes, how should they do the crowded PE classes?
In this regard, at the end of April, Guangzhou Education Bureau issued sports teaching guidelines, pointing out that when outdoor sports, on the basis of keeping a safe distance between each other, you can not wear masks.
It is understood that many schools in Shanghai have also improved the way of physical education classes. On the premise of safety, encourage taking off the mask and taking physical education classes.
On May 8, the website of the National Health Commission also released the latest notice that students in schools in low-risk areas do not need to wear masks.
Five points suggested that experts should give advice
to the epidemic for a long time. Everyone was forced to stay at home and lacked exercise.
With the decline of epidemic risk levels in various parts of the country, people are eager to go out of the room and start outdoor sports.
This is not only to keep fit, but also to show a good figure in the coming summer.
Experts have provided you with five suggestions on how to exercise more scientifically and safely :
① do not wear masks when exercising at home. In order to avoid accidents in patients with potential heart disease, the intensity of exercise should vary from person to person, step by step, and do not rush into it.
② After the students resume classes, it is recommended that outdoor sports should be given priority to as much as possible, keeping a safe distance of 1-2 meters, and do not conduct long-term, moderate and high-intensity confrontational sports.
③ adults, no matter indoors or outdoors, do not wear masks if they perform strenuous sports with more running and jumping.
④ the elderly should focus on soothing and stable exercises, and can adopt abdominal breathing, taijiquan, arm lifting in turn, etc.
⑤ running enthusiasts should try their best to choose places with relatively few people and good ventilation, keep a distance of 2 meters from others, and do not run in piles. They can choose to run in different peaks or in the morning with relatively few people.
