No, dental hygienists don’t stand there with a mask on for six hours. But they work 8 hours shifts and during that time for most of it they’re wearing masks.
I’ve witnessed the hours of three surgeons on one day of surgery (three surgeries) because I saw their names on the massive schedule in the waiting room which shows all their surgeries for the day. They had back to back surgeries (knee, heart and eye, respectively, for my BIL, niece and SIL) for most of the day. Surgeons work 60-80 hours typically a week.
So yeah. They do wear masks for hours per day on their surgery days.
And what of surgeons who do complex surgeries that last 6-10 hours? Those aren’t new. That shows that indeed, health care workers are wearing masks for extended periods and have been for decades.
And parents of cancer patients who are with their child for days in the cancer ward? Wearing a mask the whole time?
Of course, like I said, they’re not stapled to anyone’s face. No one leaves a mask on for hours without taking it off for at least a bit to eat, drink, etc.
But there is not one shred of data that states there is a risk to kid’s developing brains or carbon monoxide poisoning when wearing a mask for a lengthy time period. That’s what this conversation is about. That’s what you stated. That you think it wouldn’t be good for kids’ developing brains. But you have no evidence to back that up and it should be everyone’s goal to stop misinformation that can hurt us.
But like I said, I don’t know that it’s feasible to have all kids wear a mask all day at school. They’d take it off, touch it, get it dirty, and to wear the same mask would likely defeat the purpose. But some kids do do it:
“Some schools in Taiwan have required students to
wear masks at all times, according to Taiwan News.
Second and third graders in Israel
wear protective masks while in school, but not in the classroom.”
