A new study by American scientists refutes the claims of some that the use of a mask due to coronavirus can cause toxic effects due to the trapping of carbon dioxide on the exhale. The new study concluded that such a risk is negligible.
As the "negatives" of the mask make more and more noise about the supposed dangers of the mask or that it is supposedly unnecessary, the vast majority of scientists around the world agree that the mask is necessary - even as a necessary evil due to discomfort - for limiting its spread Covid-19.
The new small study, led by Dr. Michael Campos of the University and Medical Center of Miami, published in the American Pulmonary Journal "Annals of Thoracic Society", assessed the possible problems from using the mask in both 15 healthy and 15 healthy people. with Chronic Obstructive Pulmonary Disease (COPD), with an average age of 72 years, who had more difficulty breathing.
"We have shown that the effects of the mask are minimal even in people with very severe lung dysfunction," said Dr. Plain. As for the shortness of breath that some people feel when wearing a mask, he pointed out that it is caused by the restriction of air circulation, but does not cause any toxic effects from increased carbon dioxide. As he said, shortness of breath can be felt even when going uphill quickly.
He even added that an overly tight mask can intensify a feeling of discomfort due to shortness of breath and advised those who have such a problem to take off the mask as soon as they are at a safe distance from others.
The scientist stressed the importance of wearing a mask to prevent the spread of coronavirus SARS-CoV-2. Especially those who have lung diseases, as he noted, should wear a mask, because they are more at risk than Covid-19.
"It is important for the public to know that the discomfort associated with the mask should not lead to non-existent safety concerns, as the mask has been shown to improve public health. "The public should not believe that masks kill," said Kampos.
