16 Mysterious Objects That Puzzled People, but Answers Were Found on the Internet

Using a public restroom is often an unavoidable but less-than-pleasant experience. Many of us instinctively cover the toilet seat with toilet paper, thinking it provides a layer of protection from bacteria. However, research suggests this common habit may not be as effective as we assume.
Every time a toilet is flushed, tiny particles of fecal bacteria get released into the air, settling on nearby surfaces. This means bacteria aren’t just on the toilet seat but also on bathroom walls, sinks, doorknobs, and—most notably—on toilet paper rolls. Since paper absorbs moisture well, it creates a prime environment for bacteria to multiply. As a result, covering the seat with toilet paper may just be layering bacteria upon bacteria rather than preventing exposure.
Some public restrooms provide plastic shields over toilet paper rolls to minimize contamination, but many do not. And while flushing with the lid down could reduce the spread of bacteria, not all public toilets have lids, making it impossible to control what has already been exposed.
Contrary to popular belief, toilet seats aren’t the dirtiest parts of a restroom. Microbiologist Charles Gerba points out that frequently touched surfaces—such as door handles, faucet taps, and toilet paper dispensers—pose a greater risk, as they come into direct contact with unwashed hands. In comparison, toilet seats typically have less exposure and are often wiped down by users before sitting.
Since toilet paper in a public restroom is already exposed to airborne bacteria, using it to cover the seat doesn’t create a truly protective barrier. Instead, it may be more effective to carry personal sanitary tissues or disinfectant wipes for added cleanliness. If neither is available, avoiding direct contact with the seat altogether might be the best approach.
Although public restrooms contain bacteria, the risk of catching an infection from a toilet seat is quite low. Most bacteria and viruses don’t survive long on the surface, and actual infection typically requires direct entry into the body, such as through an open wound or the urethral tract. As long as you practice good hygiene, your immune system is likely capable of handling any minor exposure.
While the risk of infection is minimal, following these simple hygiene rules can make your restroom visit even safer:
While covering a toilet seat with paper might not protect you, there’s another habit that could be even worse for your health—holding in your pee for too long. You might not think much of it, but your body definitely does. Find out what really happens when you resist nature’s call.
