The station swabbed a few men’s beards and discovered some examples of unfavorable bacteria. But they didn’t swab any clean-shaven men’s chins. If they had, there’s a good chance they would have found similar bacteria on those chins, too.

Some of the bacteria in the beard study is comparable to bacteria commonly found on toilets and in human feces. Gross, right?

Here’s the thing: Those same bacteria can be found on dozens of other surfaces you touch each day, and they usually pose no harm to you. In fact, trillions of bacteria live on or in our bodies without threatening our health.

So, Should I Shave My Beard?

If you’d like to, sure — but not because of germs.

As long as you regularly groom and clean your beard, as you do the hair on your head, you are not at greater risk for disease than people without beards.

Science is just beginning to learn about the many species of bacteria that live within our bodies and what purpose they serve. We do know that most bacteria isn’t bad for us — many are beneficial and, in some cases, required for good health.
