In some countries where lockdowns are being implemented due to the epidemic of the new coronavirus, going out is limited to shopping and exercising daily necessities. Exercise becomes more important in a life of confinement at home, but at this time there is the question, 'Should I wear a mask when exercising outside?' Many health officials have warned against exercising with a mask on, but new findings show that exercising with a mask does not affect lung function or oxygen inhalation. It was shown that.

It May Not Feel Good, But Exercising With a Mask on Shouldn't Impair Your Oxygen Intake

A April 2020 survey showed that runners' exhalation could hit people behind them, suggesting that they should wear a mask, but exercising with the mask on is stuffy. Brings the mask. For this reason, as the Ministry of Health, Labor and Welfare recommends 'Avoid heavy work and exercise when wearing a mask' in ' Points of heat stroke prevention behavior in a new lifestyle ', many scientists And health officials are warning about the movement with the mask on. 'Is it really dangerous for the body to do strenuous exercise with a mask on?', A new research team, including Susan Hopkins of the University of California, San Diego, conducted a new study.

According to the research team, concerns about wearing masks during exercise are based on experiments using 'devices designed to intentionally affect respiratory and exhalation exchanges.' For this reason, it is not clear at the time of writing the article whether 'the person wearing the mask' actually has the same effect. Therefore, the research team reexamined scientific papers that mentioned the effects of various masks such as cloth masks, surgical masks, N95 masks, and industrial gas masks, and found out the effects of exercise with masks on the heart, blood vessels, and lungs. I verified it.

The results show that exercise with the mask has little effect on blood oxygen, carbon dioxide, and other physiological parameters and may be undetectable.

Of course, research in this area is still underdeveloped, and more research is needed to say for sure. However, according to the evidence at the time of writing the article, the research team said that wearing a mask increases discomfort such as difficulty breathing, but 'Wearing a mask while exercising is a cause of lung function and oxygen. It does not affect inhalation. '

'Wearing a mask slightly increases resistance to breathing, and a person may re-inhale warm carbon dioxide-rich exhaled breath, which may increase body temperature and sweat. It's perceptual and doesn't affect the cardiopulmonary system of a healthy person, 'Hopkins said.

In addition, the survey results that it is okay to wear a mask and exercise can be said regardless of age and gender, but it is not the case for people with serious cardiopulmonary disease. For this reason, Hopkins calls for people with cardiopulmonary disease to consult with their doctor to consider whether to reduce discomfort during exercise or reduce the risk of COVID-19 infection.
