This article is just another example of how you can create a study to achieve the results you want. It doesn't explain what evidence they have proving their theory, they just give the conclusion. This is how the media conducts polls and now it seems nurses are doing the same to get people to fall in line. A similar study could be conducted proving that 99 out of 100 people had better mental well being while not wearing masks while on a vacation in sunny Hawaii. What a joke... I'm not saying you shouldn't wear masks but don't try to tell people they will feel better mentally if they do.
