This is something I often think about when using those new hand dryers in public toilets that blast high-velocity air into a confined space where some of the water removed from people's hands collects.
It seems like a great way to aerosolise whatever was on the hands of all the people who previously used the hand dryer.
- paulmd 7y agothe Dyson AirBlade and similar? Yeah, and the hand holes are none too big either, and I'm sure people bump into the sides and those get gross too. Not a fan, they kinda squick me out a bit. I guess in theory people have washed their hands by that point, but not everybody has washed them well enough. It's at least 20 seconds of solid rubbing, people, not just in and out of the water. The temperature doesn't matter, what matters is being under there for long enough the germs come off.

The temperature doesn't matter, what matters is being under there for long enough the germs come off. Anecdotally, I don't wash for anything close to 20 seconds and I'm sick much less often than my coworkers who do. I'm also not afraid to touch food with my hands >... Of those that exist, nearly all have measured reductions in overall numbers of microbes, only a small proportion of which can cause illness, and have not measured impacts on health. Solely reducing numbers of microbes on hands is not necessarily linked to better health. https://www.cdc.gov/handwashing/show-me-the-science-handwashing.html https://www.cdc.gov/handwashing/show-me-the-science-handwash...
- _-___________-_ 7y agoYeah, removal of all germs is not something I would ever be interested in. I'm keen to keep a strong immune system, thanks. Having said that, I'm also not keen to aerosolise and breathe in whatever's on the hands of the ten people who used the hand dryer before me. I like the hand dryers that blast a decent flow of warm air past your hands towards the floor, rather than an extreme flow of cold air past your hands at a pool of other people's used hand-washing water.
- c0restraint 7y agoYou can keep your germs, but please wash your hands long enough so you don’t pass them onto others. That’s why we have restaurant staff wash their hands
- Fomite 7y agoThis has been shown to be a problem. I hate them.
- thaumaturgy 7y agoWorse yet, it's not like they're using internal canisters of compressed air. They're just sucking in whatever's floating around in the bathroom atmosphere and then blasting it onto your moist hands. I hate those things.
