Masks categorically do not reduce oxygen saturation. This is a lie made up as an excuse by those who believe the pandemic is a hoax and that wearing a mask somehow encroaches on their rights. This is not an issue of freedom.

So please, wear a mask if you are worried about spreading COVID but do not worry about not getting enough oxygen. Even with lung disease, asthma, COPD, a paper mask will not make a difference to how much oxygen you inhale. COVID will. The end ?

“Does wearing a face mask lower your oxygen levels” repeatedly by patients today!
Based on what they are reading on social media
*Face coverings / masks don’t reduce your oxygen levels!*
I managed to get six face masks on + it had no effect on my oxygen levels! pic.twitter.com/qNKYa8pejx
