How often do people need to bathe?

As of 2016, new studies are showing that people do not need to bathe as often as they do. The standard for most modern cultures is to shower either once a day or twice a day. But this can cause problems.

Researchers at Colombia University have discovered that washing too frequently can dry out and crack your skin. These openings then allow bacteria and other microbes to get into your body. And although you might be washing off some of the smells of the day you're also washing off natural oils that your skin produces.

The study doesn't say how often you should bathe; only that once a day is more than necessary.
