An observational study of more than 3,000 people found 10% left public toilets without washing them at all and even if they did, 33% didn’t use soap. This matters because, unfortunately, we can’t resist touching our faces, allowing germs to spread nicely from our hands to our noses and mouths, where they can get into the body. So it’s clear that we need to wash our hands properly. The problem is there are plenty of myths out there about how to do it.
