Why do Japanese people wear surgical masks outside of hospitals?

-or that you're much more likely to suffer serious problems from vitamin D deficiency than contract skin cancer much less die from it.

 

I think in Japan, people commute mostly in packed trains. So the mask is suppose to prevent them from catching over air sickness. They do that in China too, well because the air quality is really BAD.

 

Everyone needs some level of sun. My mother, a late stage 2 survivor, was told by her oncologist to get 15 minutes of unprotected sunlight a day. This is also a culture that celebrates being ghostly pale.

 

It's also believed that when you're sick and wear a mask (especially when sleeping), it prevents your throat from getting too dry and making your cold worse.

I'd love to wear one in Australia when I have to go out while sick. Not only would it stop me coughing and sneezing my germs everywhere, it would hide the fact that I'm mouth-breathing.

Mouth-breathing just looks so dopey!
