Turns out masks are not made of asbestos.

Unsurprisingly, masks safety and effectiveness has been studied extremely extensively.

certain groups (nurses, doctors or certain workers) have to wear a masks all of the time for years. It would have definitely been noticed if it would cause such effects...the control group exists, just compare it to the rest. It would have been obvious.

But those groups are particular ones that are also exposed to other environments that affect health so any discrepancy will be hard to attribute.

Also, doctors did not wear masks to the extend we did during Corona. They'd only wear them during some surgery, not the whole day including even outside.

Indeed. Nor were they wearing the same one again and again for months on end, and stuffing it in their jeans pocket in between.

True, I used a fresh one every day during the worst of it, but I have to say I've gone back to doing exactly what you describe. The only place I still need one is public transport and now that it's getting hot (Spain) I often go outside without a coat, so my pocket is the only place to leave it. And it seems like a waste to replace it after one 15 minute ride on the subway.

And I'm not the only one, I've seen a lot of people wearing ones that are all fluffy from long use and sometimes washing (some people really wash disposable masks). I'm sure that will increase shedding a lot.

On the contrary, there's been plenty of doctors and lab technicians wearing masks full time and for decades!

Not to mention semiconductor workers.

And industrial worker dealing with hazardous materials.

Like hanoz says above, what professionals wear is not really comparable to what people wear on the subway these days. It's the cheapest of the cheap Chinese crap, and usually used so long and mishandled that it is becoming really fluffy. Especially now that nobody really cares anymore and the use of them is incidental they end up being lugged around more than worn and not frequently replaced.

A fresh mask doesn't shed a lot but I've seen ones that are all hairy and stringy from being rubbed around in pockets with other stuff. I'm sure they shed a lot more material than a fresh mask.

And a lot of the types you mention would not wear masks like this but powered respirators (e.g. people working in clean rooms)

Personally I have major issues the masks for past medical trauma reasons but I really don't think they are healthy to keep around forever.

>>certain groups (nurses, doctors or certain workers) have to wear a masks all of the time for years

Not really - doctors/nurses etc have for a very long time worn masks for short periods of times, for certain procedures, for certain hours of the day for some days in the week- very few HC professionals have ever had to wear masks continually all day long, day after day and then also for additional chunks of time as they go about their non-work life.

Agreed.

However on the other side: there were some rather poor quality masks produced during the pandemic, so I would not be surprised to see future data about those being linked to health problems.

>>Turns out masks are not made of asbestos.

Neither are cigarettes, but getting enough cigarette smoke in your lung does causes cancer.

It also turns out masks are not made of burning cigarettes. How many more of these do we have to do?

At this point I can expect anything from this thread. Some conspiracy theory claiming that masks are manufactured by aliens.

”Fun” fact: cigarette filters were made with asbestos.

> From 1952 to 1956, Lorillard Tobacco Company's Kent Micronite cigarettes were made with asbestos filters. The filters were advertised as increasing the experience and safety of smoking
