    I think a mask is your best option. If you’re trying to prevent against other people’s illness, you probably need an N95 mask, something that seals around your mouth and nose. A surgical type mask is more to control the droplets and spread of illness coming from you.

    Everyone is answering about wearing a mask, when the poster clearly makes the point that they don’t have one. They can’t just poof it from the air. The answers are not helpful.

    The question is about whether shallow breathing and nose or mouth breathing is better. It’s a very particular question. An interesting question.

    Does anyone know, with real scientific knowledge, what the answer to this specific question is? Can anyone answer to the specific question?

        I believe that if OP had a mask in this situation, they would most likely wear it. So we should assume that they don’t have one

      I know that breathing through your nose is generally better than breathing through your mouth for the simple fact that your nose has special follicles that act as a filter. But honestly the eyes and nose are most sensitive to infection and that’s part of the reason people are suggesting masks. It’s to lower the number of mucus membrane vectors for infection.

      Op is more likely to get sick, especially if the other sick person isn’t washing their hands and cleaning surfaces they touch, and limiting the amount of time touching their own mucus membranes.

        Tons of viruses replicate in your sinuses (like covid), so idk if nose breathing would be the right answer.

        Really, flushing out your sinuses after exposure is the best option if you can’t wear a mask.

          But if you inhale through the mouth as the alternative, you’ll directly track the viral load to the lungs which also had mucus and the viral load would multiply there instead. So take your pick. At least the nasal passage has some defences.

        Masks are suggested not for your own safety but for the safety of others… as you mentioned the eyes are quite sensitive to infection so masks on public transit aren’t an effort to keep germs in the air from getting to you - they’re an effort to prevent germs from getting in the air.

        You didn’t hear that talked about much during the pandemic because, if we’re honest, most people are assholes… they’ll bear a minor inconvenience to keep themselves safe but couldn’t be assed to keep anyone else safe.

        What a mask does do for you is to keep you from touching your mouth or face in general… that can be quite effective at reducing illness and, post-covid, I think we should all be more aware of doorknobs and other shared surfaces.

          No offense but this was explained many a time during the pandemic, especially in relation to immunocompromised people. If op can’t mask I doubt there are any breathing techniques they can use to prevent them from getting sick. But cleaning anything they touch and washing their hands is as good a solution as any.

      Nose. More filtration mechanisms and also make you breathe shallower, which is better.

      Alternatively, hold your breath until you die. You’ll never get sick again.

      The question is about whether shallow breathing and nose or mouth breathing is better.

      Doesn’t matter.

      Think simple: One breath moves a few liters of air. Doesn’t fit into one nose or one mouth. It must flow through. You breathe maybe 30 times per minute.

      Try to do it “shallow”? Just try it out for a whole minute and watch LOL. No, you need all the air, each minute.

      Move all the air through the nose or through the mouth? The virus doesn’t care. The virus can get you through all your membranes.

        You breathe 12-20 times per minute, not 30. Average breath is under 0.5 liters, not a few liters.

    As everyone else is saying, wear a mask if you have one.

    But it seems like the question you’re directly asking is more about the fluid flow of air in the room. With your suggestion of alternating short/long breaths, you might be imagining that you can blow the germs away and then breathe in the clear space left behind, but of course it doesn’t work that way. Blowing or breathing quickly creates more turbulence, which stirs up the air and sucks in more air from further away—both of which increase your risk. (Reducing turbulence from your breath is the second function of a mask, besides filtering out particles.) In the best-case scenario, the germs are in large aerosolized droplets which will settle out of the air quickly, but only if the air is still—so you’d want to breathe softly and move as little as possible. (And the droplets can still be infectious after they fall, so wash your hands after touching anything as well.)

      And wash your hands after leaving the area as well, because some of those droplets will have landed on your hands.

      If you use a public bathroom to wash your hands, assume the sick person was in there earlier and touched the faucets, soap dispenser, towel dispenser, and door handle: get towels first (plus one extra), get the soap on one hand, then turn on the water and wash your hands. Dry your hands and turn the water off with the paper towel, then use the spare paper towel to open the door.

      Thank you for addressing my question. I’m aware of masks, lol. Any idea about nose vs. mouth breathing? Nose hairs filter some stuff, but then these aerosolized droplets are in my nose, so maybe that’s worse?

      Regarding short vs long breaths, I was kind of wondering if short breaths might limit how much virus material was inhaled. Restricting oxygen flow might be better if the exposure was short term.

        I probably heard most of this from the Magic Schoolbus, so don’t take me as a concrete source of truth.

        My intuition says that you’re at a lower risk by breathing through your nose. How much lower, I can’t say, it might be marginal.

        The mucus in your nose is part of the immune system. It’s designed to trap foreign particles and prevent them from getting deeper into your respiratory system.

        So with that in mind, I’d think that blowing your nose after exposure could be a safe bet. But make sure to wash your hands before you touch your face. Maybe after too.

        But since there’s overwhelming evidence masks work and will prevent (most likely) what you want to prevent…why even try something else? Unless you have a condition that prevents it, in which case, I’m sorry and shouldn’t assume you can wear one.

          Because I don’t always have an N95 mask on my person? Because I can’t always 100% control my environment, but I can almost always exercise some control over how I breathe?

            I guess that’s fair.

            I’ve just adapted to always having a mask on my person. In a pocket or bag.

            But if there is some sort of breathing technique that works (other than not breathing, but sort of doubt) go for it.

            I just wanted to state my opinion and I guess my problem solving technique (the easiest and most effective/reliable option is usually best) but everyone has their own, and I understand that.

    Here’s a very technical paper that studied nose vs mouth vs combined nose-and-mouth breathing:

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7455204/

    I confess it was over my head and I just skimmed it. But the conclusion says, “The high filtration efficiency of the nasal cavity together with its efficient clearance mechanisms lead to the recommendation to prefer the nose breathing over combined or mouth breathing.”

    The conclusion also says, “There is general scientific agreement that lower airways are more vulnerable to severe infections” and “From this point of view, the nasal inhalation is preferential because it significantly reduces the number of particles penetrating to lower airways.” I’d guess that means that shallow breaths are probably preferable, but you’d need to read the article to confirm that.

    I remember learning in school that breathing through the nose is healthier than through the mouth because your nose is capable of filtering the air to some extent, some particles are going to get stuck in your nose rather than travelling further inside your body.

    Wear a mask and GTFO when you can. If it’s an airplane you can’t really do anything but hope and be extra cautious not to touch your face (a mask can help with this)… if it’s a bus or something then just GTFO unless it’s really low frequency and catch the next.

    Knowing the type of area would help.

    Medically the nose is far better equipped to deal with pathogens, so breathing through the nose would be better, both in (to “filter”) and “out”(to get right of stuff). More important, nevertheless is proper hygiene - wash your hands, fellas. And do not touch your face,but especially not your nose and eyes after you have been exposed to germs.

    Besides that there is literally zero evidence for anything else - the very limited research in some breathing techniques has all been debunked sooner or later.

    If you want to be sure,wear a proper N95/FFP2 mask. Proper means: Tight fitting, the right size for your face (not the cheap ones from the truck stop).

    if someone coughs or sneezes in the same room as you, hold your breathe for 10-15 seconds if you can. some airbornes are floating around even longer than that but its something.
