There was a peer-reviewed report published in the journal for Applied and Environmental Microbiology that studied the amount of bacteria that was blown from hand dryers in 36 public restrooms at the University of Connecticut School of Medicine. The sample from the study concluded that as many as 60 colonies of bacteria were blown from a hand dryer in just 30-seconds. A number of those bacteria were linked to fecal and human bacteria, even bacteria known to cause serious infections.
Why YSK: So that you are informed for your own health, hygiene, and wellness and to prevent further spread of more harmful bacteria.

Well, it’s from your (and other people’s) hands, onto everywhere.
Still, AFAIK it’s not clear if this is a problem.
Which is why food service workers are required to dry hands on disposable paper towels.
Where is that the requirement? I’ve worked several food service jobs and they only had air dryers.
And nobody wondered why your customers kept getting norwalk?
There is no such regulation.
Illinois, at least.
God I never gave that a second thought but they’re right, its just sucking in and blowing farts onto my clean hands
If the blower is blowing fecal matter then it would also be settling all over the paper towels. Issue is placement not anything to do with the blowers.
Luckily paper towels are stacked though, so I’ll just avoid wiping my hands with the folds.
Almost every public restroom I’ve ever been in has the paper towels and toilet paper locked in a closed dispenser unit.
Bathrooms should just have a unisex hand washing station away from the toilets. May not work well for older buildings but new developments can implement that easier
I can’t remember where I saw this so take it with a grain of salt… But I remember that the set of studies to come out on the sanitary condition of air dryers was funded by the paper towel industry. Not that the studies aren’t correct or anything, but I do think that it’s something to consider.
Yup, the air blower companies have also funded anti-paper towel studies. It’s somewhat funny.

That was a very interesting read, thank you!
… And a large portion of dust is dead skin cells. Also, during the springtime trees straight up bukake your face and lungs.

Me during spring time 😭

Just do what I do and wipe your hands on your pants because those blow dryers are virtually worthless. I’d have better luck blowing on my hands myself.
Bonus: My pants aren’t covered in fecal mist… I hope.
Fecal Mist, great name for the new Enigma album.
Narrator voice: “They were”
Basically everything is covered in fecal matter of you look well enough, and it doesn’t really matter. It’s really good for selling disinfectant though!
Well I have to touch the door on the way out any way so it really doesn’t matter that much.
I’m pretty sure that regardless of where you are or what you’re doing, fecal matter is getting blown on your hands. Mythbusters tested this out once by putting tooth brushes all over their shop and then culturing the bacteria from them. IIRC the ones that were in the bathroom had the least amount of fecal matter.
The thing I remember is that even the control toothbrush that got opened and immediately locked away had fecal bacteria on it.
Paid for by the paper towel industry which was in response to the hand dryer industry putting out it’s own paid study about how paper towels just spread fecal matter around your hands. It’s all shit no matter how you spread it.
I still prefer towels for how fast they are. The Dyson ones are pretty similar though
yeah ther’s so much paid propaganda around paper vs dryer that I don’t know what to believe anymore.
i personally prefer paper, only because it’s usually faster for me.
This comment is the shit. It made me lol.
So, the best is to bring your towel paper everywhere.
The best is to wash with wotah
Yeah, what a shit show
Literally everything in the restroom is covered in that… Including the air you breathe. Enjoy!
Smell is particulate. You can smell the last guys poo because little pieces of it are landing in your nostrils.
Thank you for that
It’s not easy to convey important information when it comes to biology IMO.
Yeah we breath in fart and poop “particles” all the time, and a whole bunch of other stuff.
I don’t know about the idea that every time you take a breath you inspire some molecules from when Ceasar said “et tu mon Brutus”, or any other inspiring phrase, but also from one of Hitlers farts.
Molecules are small, really small and there are really many of them.
Our immune system works really hard, crazily hard even, and it’s not a simple mechanism (we basically don’t know how it works) but if you want to know if a fan blowing air or towel or a one usage towel is good or bad (or obviously how they influence our wellbeing) you have to do a real study. By scientists, and not by news looking “journalists”.
BTW fact of the day to throw you off: there are somewhere around 600.000 cells that divide in an adult human body every:

Speak for yourself
Well yes, but no.jpg
The heart is extremely bad at regenerating, classic muscles the opposite for example.
Then let’s not get started on consciousness and memories plus our physical body, which is who we are today (or ‘now’)…
So somehow yes.
And good night I’m off to sleep !
Yeah if there is nothing but blowers I just wipe my hands on my pants. If the blowers could somehow bring in outside air that should be better, but that complicates the install and maintainence.
Just wait a minute and your hands will dry on their own. Ideally you used soap and rubbed them together under the water long enough so they are clean. You did, didn’t you?
Why are you talking down to them? Don’t be rude.
You don’t wash your hands. Your hands wash each other and you watch.
So weirdly antagonistic.

Well you did, and I did. But think about how many did not, when you open the bathroom door after meticiously washing and drying your hands…
what part of that post made you think he wasn’t washing his hands? the part where he described how he dries them?
Still cleaner than the doorknob. I hate opening a restroom door. The stuff I touch going in will land on my genitals, on the way out everywhere else, like my face and food.
