My masks have a blue side and a white side. Should I wear it with the blue side out like you do or does it make no difference?
-
Yes, blue out.

Of course masks lower your 02 level ... sure if its on social media surely its true

If masks lower your 02 level, to any appreciable degree as to cause problems.. isn't it logical that medical professionals who wear them 8hrs + a day every day would experience issues? Not even respirators, just surgical masks here. They're quite breathable and don't limit air

Since 1987 in Irish hospitals, pharmacy technicians preparing cancer treatments in cleanrooms have routinely worn face masks for upto 8 hours per day. I have never encountered any staff with breathing difficulties from a face mask in all that time.

There is no such thing as a stupid question, not asking but lacking knowledge that is silly. Mask wearing is brand new for some. Whatever alleviates worry is good in my opinion.
