For women, peeing in a public bathroom is kind of a big deal. Lots of ladies choose to hoover over the toilet seat, in an effort to avoid germs. But it turns out when it comes to the bathroom in your house it’s the toothbrush holder that harbors the most germs.
A 2011 study found toothbrush holders contained mold and yeast, and some had coliform (meaning they may have had poop particles on them.) Time reports that overall, bathrooms can be full of germs, so the take-home message is that you should wash your hands frequently (and also use paper towels from a motion-detection dispenser) to avoid spreading around bathroom germs. Researchers add that most of the bacteria in bathrooms pose no harm to humans.
