The head of the therapeutic department of the Israeli hospital Shamar Asaf Ha-Rofe, infectious disease doctor Galina Goltsman appreciated the idea of wearing two masks to protect against COVID-19. RIA Novosti quoted her words.
The infectious disease specialist stated that wearing two masks at the same time, practiced by some American officials, is in no way justified from the point of view of the available scientific evidence. In addition, this method can lead to drowsiness, so the specialist recommends using one face shield.
“They want to wear two masks – let them wear them, but this does not need to be done, one mask is enough. Each item also has a negative effect, because when a person breathes, he emits carbon dioxide. On the one hand, two masks, of course , protect, through them fewer particles of the virus can penetrate, but on the other hand, a person inhales less oxygen. He creates an increased content of carbon dioxide around his nose and he may experience fatigue, drowsiness, and an increase in carbon dioxide in his blood ” , – said Holtzman.
The doctor recalled that a person wearing a regular mask in compliance with the rules, in the case when he communicates with another person wearing a mask, is reliably protected from COVID-19 infection.
Several US officials, including current US President Joe Biden, were previously seen wearing a protective cloth mask over an N95 respirator.
The World Health Organization (WHO) advises people who have had COVID-19 to continue to comply with antiviral measures, including wearing masks and staying physically away.
