And no mention how much do they slow down or redirect exhaling of viral particles (esp when eg coughing), thus enabling those air filtration systems to do their work (eg. in an airplane).
When you can't tell if you are infectious or not, by wearing a mask, you are reducing a risk to them, and signalling that you care even if you are confident you are not sick (eg. you've had it a month ago).
I am not sure why is such signalling considered useless: it makes everybody around you more relaxed.
- timthorn 5y agoI'm not sure it does make everyone more relaxed. It's a signal that there's a danger around so heightens tension. In the UK I'd guess that less than 10% of people are still wearing masks based on observation so when the culture of mask wearing goes it seems likely that most people relax.
