A mask worn properly (something that is not difficult to do) does not restrict oxygen flow to any sort of negative way. Calm down.

"What OSHA states on its COVID-19 FAQ webpage is masks may not be appropriate for certain kinds of workers. “For example, cloth face coverings could become contaminated with chemicals used in the work environment, causing workers to inhale the chemicals that collect on the face covering.” according to OSHA."
Stop spreading lies about OSHA and other things.
