It’s called toilet plume.

A toilet plume is the invisible to the naked eye, cloud-like dispersal of raw, infectious sewage particles as a result of flushing a toilet. Flush particles rapidly rise out of the bowl and several feet into the air after flushing. Aerosolized droplets can remain suspended in the air for tens of minutes between users, posing an inhalation risk. These invisible particles go on to coat and spread onto surfaces like floors and counters or objects like hand towels, bathmats, or even toothbrushes.

    How about we quantify how dangerous the farticles are first, before we decide how useful closing the seat is? Who cares how many invisible particles it stops if they turn out to be harmless?

      I can not be the only one who is very aware, whenever i smell a fart, where those molecules were before they were in my nose.

      Agreed. Obviously there are some things that, as we acquire new knowledge that may change daily behavior, need to be reconsidered, but this is not one of them. People will look for the dirty hypodermic in the haystack of swords.

      There’s so many other things to care about more. In the age of information, our mental health depends on conscious gate keeping of what we allow to concern us and modify our behavior. Everyone needs to decide their own path but if you don’t and just scroll the feed you’ll go mad.

      true, but if I gotta close the lid anyway to stop the cats from drinking from it, I may as well do it before flushing rather than after

        Well you should be far more worried then. Because closing the lid or not won’t matter. Your toothbrush is covered in it anyway. Unless you’re covering your toothbrush when you’re not using it.

    You close the lid to avoid a plume of fecal particles. I close the lid because otherwise my dumb cat jumps directly into the bowl. We are not the same.

    I’ve put the toilet lid down since that mythbusters episode where they examined how much fecal matter got onto toothbrushes that are in the same room as the toilet.

    Now my toothbrush isn’t in the same room as my toilet but I still shut the lid.

    Spoiler for the mythbusters episode… It was a lot of fecal matter… A lot.

    People are fascinating.

    There are people who follow the “10 second rule”, i.e. food hits an unclean surface like the floor and they will pick it up and eat it.

    Meanwhile, every single person who was born naturally has been shit on at birth. This is a thing that happens. And studies show that excessive cleaning of newborns leads to all sorts of allergies.

    So there has to be a balance.

    I’m sure a non-zero number of people have gotten ill from toilets flushing. I’m also sure that number is pretty small. And I’m as sure from studies that show that keeping the lid closed still lets particles out that it’s going to happen.

    I’m of the opinion that this is a very small problem.

    But as it happens, I keep my toothbrush at my desk because it’s more convenient for me.

    So if it bothers you, keep your toothbrush in a cabinet and/or in one of those little cases.

      Everyone knows there’s no such thing as a ten second rule.

      It’s a five second rule.

      Also, to the shit thing; it’s a very well established fact that shit spreads tons of disease and infections. You sound dirty for just trying to bring up the counter point of getting some shit on you at birth and I don’t want to shake your hand.

      Also, the 5 second rule is bullshit. Those people are yucky.

        you sound dirty

        And you sound ignorant. I can wash but can you learn?

        Also, mothers shitting on babies being born not only is the reality, but considered to be important in developing the immune system.

        Do try to be better.

        Edit; five second rule is nasty, yes.

      Yeah, I’m of the mind that if I can’t sense something, and I’m not getting sick all the time because of it, it’s not bad enough to avoid. Lo and behold, I almost never get sick, even when my wife gets sick all the time. Now, it could absolutely be confirmation bias or some hidden 3rd factor that’s causing this, but either way, bring on the fecal matter mistings!

      Because cleaning those surfaces is extra work, toilet is already in a stall that helps inhibit the mist, and the door handle you use to get out is dirtier than anything else in that room.

    “A 2024 study showed evidence that even closing the lid may still lead to small viral particles escaping through gaps under the lid, resulting in viral cross-contamination of the air and surfaces in a washroom.”

    This is what I remember, there’s no actual solution to this. Still close the lid though!

      That same study also includes this figure,

      But the study doesn’t measure other surfaces or things like “a nearby sink” or “a hand towel”. Perhaps for airborne particles they roam more freely, but what about surface particles? I feel like there is more to study.

        This is similar to why we all wore masks during the pandemic. No, they’re not always effective, but yes, they reduce transmission rates.

          Yes, but there is incredibly strong evidence that mask wearing does reduce transmission rates. I haven’t looked (so definitely correct me if I’m wrong), but I suspect that lid closing likely does not have strong evidence for decreased transmission.

          One factor that I think likely weighs heavily into this is that public toilets, where you could be exposed to particles from a stranger dont have lids usually, and they have a much more violent flush, while home toilets are mostly just used by your own household.

            We’re not necessarily talking about transmission in this case, just the concept of poo particles spreading widely throughout your bathroom vs less widely

            Idiot-proof is a misnomer. Better term is idiot-resistant.

            Related note. I’m very sad that there isn’t a joke ANSI or ISO document laying out specifications for idiot-resistance standards.

      Of course nothing’s 100% poof. But that doesn’t mean that you should stop. There is a massive difference between the particle numbers.

      But if you close the lid, all the particles concentrate on it. Then when raise it back up and sit down, there’s a chance you’ll pick it all up with your back.

      So the question becomes, do you want shit more evenly spread out in the air or do you want concentrated shit on your back?
