Bathroom Hand dryers suck in fecal bacteria and blow it all over your hands, study finds
Everyone knows fecal bacteria expels in the air when a lidless toilet flushes this event is known as a “toilet plume.”But in a bathroom where such plumes gush repeatedly, where do all that fecal bacteria go ?
And discovered they were separating “Bacillus subtilis”, a bacteria generally found in human wastes, all over the room.
Are Bathroom hand dryers actually hygienic?
Debris, like dust and skin but also microbes, are constantly being flowed through a public restroom as people move in and out.
Particularly when a lidless toilet is flushed.
Because hand dryers absorb the ambient air in the restroom and then blow it out at high velocity, these machines actually expose you to more microbes.
At least, that’s what the latest study discovered after expanding bacterial colonies collected from either bathroom air or blow dried air.
The team of researchers examined airborne bacteria in 36 bathrooms at the University of Connecticut School of Medicine.
In all examined bathroom, the researchers found a lab-engineered pull of the common soil bacteria Bacillus subtilis called PS533.
This strain is never found in nature and exclusively appears in laboratory settings.
What occurred was bacterial spores likely traveled from labs, either carried by air or people’s movements, to all sorts of other rooms in the research building, including bathrooms.
The PS533 strain is totally harmless to humans but its presence in each and every one of the tested environments highlights just how simple it is for bacteria to spread.
Earlier, another study discovered that hand dryers spread 1,300 more virus clumps than paper towels.
Sadly, paper towels create waste, so perhaps not drying your hands at all might be the best thing to do.
