>>12274461Anti-maskers are absolutely beyond retarded but it has been shown that if you spend 24 hours with a mask on and never take it off, you do actually breathe a not great amount of CO2. I could find a study somewhere. It's probably not very unhealthy unless you're doing it every day for weeks, and it'll depend on the mask.
Probably just taking the mask off for a few seconds to get fresh air every few hours largely mitigates it, though. That's my guess anyway. Unless you work in a service industry job, you should have plenty of opportunities to do that. And if you do have such a job, just take a break occasionally. It's unlikely you'd need to keep a mask on absolutely 24/7 with not a single second with it off.
