Face masks protect against COVID-19. That’s the conclusion of a gold-standard clinical trial in Bangladesh, which backs up the findings of hundreds of previous observational and laboratory studies.

That’s based entirely on an article written by Dr. Russell Blaylock, who has pitched several dubious claims over the years and writes an alternative medicine newsletter. Swann focused on the section of the Blaylock article that said health care workers have reported getting headaches with prolonged use of personal protective equipment, which is backed up by two studies cited in Blaylock’s article. Those studies looked at health care workers who wore N95 masks for hours at a time, not shoppers wearing a cloth face covering to go to the grocery store.

Vaccines are also one of Blaylock’s many targets. He insinuates that the H1N1 virus may be the product of some pharmaceutical research project gone awry, or that it may even be a man-made virus purposely released by someone with the “Illuminati Depopulation Agenda.”

Face masks do not decrease your oxygen intake
They also do not make you retain more carbon dioxide than usual
Oxygen and CO2 are very small, so they can easily pass through a face mask
Droplets are much larger in comparison, and they cannot pass easily through a face mask
Wearing face masks now helps us get back to normal sooner
