NOVA How Dirty Are Public Restrooms Video

So, how dirty are public restrooms? And if you knew the answer, would you ever use one again? Gross Science, a YouTube series created by PBS’s NOVA program, recently decided to investigate how dirty public restrooms actually are and found that they’re about as gruesome as you’d expect.

How ugly are things in public bathrooms? Some uncomfortable facts to consider as unearthed by Gross Science:

  • Human bacteria can recolonize a bathroom just one hour after the bathroom gets disinfected and those bacteria can survive for hours.
  • Toilet seats are loaded with both gut and vaginal bacteria.
  • If you live in a college dorm, do not keep your toothbrush stored in it — researchers have found that there’s a good chance it will get infected with live fecal bacteria that flies through the air during toilet flushes.
  • Hot air driers can also help spread bacteria if people don’t thoroughly wash their hands, which is why you should hope people use paper towels instead.

All told: It’s pretty disgusting. If you started carrying hand sanitiser with you whenever going into a public bathroom, we wouldn’t blame you.
