Researchers looked at how masks affect the levels of carbon dioxide and oxygen in the human body.

Most scientists agree that wearing medical masks limits the spread of SARS-CoV-2: they stop drops from coughing and sneezing, which contain coronavirus particles. As a result, if a person receives a viral load, it is much less than if he were without a mask, writes MedicalNewsToday.

But what do we lose when we wear cloth bandages? Some experts began to insist that masks pose a threat to health, since they reduce the amount of inhaled oxygen and increase the amount of inhaled carbon dioxide..

To test this theory, the researchers recruited 15 colleagues who had no lung problems and 15 older adults with COPD, a chronic obstructive pulmonary disease.. Blood oxygen levels, expiratory carbon dioxide concentrations were regularly measured in two groups, and all participants wore masks..

As a result, there were no clinically significant changes in any of the measurements after 30 minutes of wearing the mask.. And even none of the participants with COPD had any significant problems with gas exchange..

The experts concluded: if a person has shortness of breath while wearing a mask, then this is definitely not the result of a drop in oxygen levels or a jump in hydrocarbon levels.. Medical dressings, although uncomfortable, are useful as a means of protection against coronavirus infection.
