In Japan, it’s quite a common sight to see people walking around or going to work wearing surgical masks. The reason is so they don’t spread germs to others, or potentially catch others’ germs, and they’re all over the place this time of year when people tend to get colds.
However there’s another reason you might see women wearing a surgical mask: research from Hokkaido University says that wearing a mask makes a woman appear significantly more attractive. And if they’re wearing a pink mask, then they basically turn into a supermodel.
