Hand dryers collect feces particles, spray them on you, study says

Study shows bathroom hand dryers spray fecal particles onto hands

There was bacteria contamination inside the hand dryers, waiting to spread to the next person who dries their hands with them.

Though the air coming out of the dryers may be clean to begin with, it pushes around bacteria from the restroom that ends up on your hands, according to a study of 36 men's and women's bathrooms, Business Insider reports.

Bacterial feces can become "aerosolized" from the flushing of toilets, one of the researchers told Newsweek.

Another might be because they don't want to use toilet roll to dry themselves because that's disgusting.

A hand is illuminated. Unlike other types of B. subtilis often found in soil, this strain is only found in laboratory environments. And while evidence shows dryers can cover hands in bacteria, they said, it's not certain whether they deposit bacterial spores. Although these particular spores, which can survive for years, are "meaningless" for human health, their vast distribution shows that bacteria had spread through the air of the entire building. The study found that restrooms with hand dryers had up to 254 bacterial pathogens present.

American scientists have concluded that hand dryers are the breeding grounds of harmful microorganisms. Although that's a lot, it certainly isn't flawless.

Researchers say the hand dryers are not only just spreading bacteria to your hands.

The scientists also explored the effectiveness of using high-efficiency particulate air filters with the hand dryers. The hand dryers apparently not only blow out hot air, they also "suck in" air that's in the bathroom, the article states.

For now, Setlow is sticking to paper towels-as is the University of CT, which has added them to all 36 bathrooms surveyed in the study.
