Just for perspective: I am a man in my mid-40s and for as long as i can remember i had this question… is it normal that i can shut my nose close just with some muscles?

I always wondered why some people hold their nose shut with their fingers while jumping into a pool or when exposed to some horrible smell… i never had this need. Changing my sons diapers? No problem! Cleaning the latrines while in the army? Just a breeze!

Ehm… yeah… just thought about this…

    No but I can close the air duct just above my soft palate (not really sure what that part is called), so effectively I can’t breathe through my nose but if I were to go underwater water would still get in, if that makes any sense. I’m not sure if this is common. I know that that part is supposed to close automatically while swallowing to prevent food from going up in the nasal cavity, but idk how common it is to be able to control it separately. It’s handy to avoid smells without using my hands though :)

    Shut from where?

    Shut your nostrils completely? That doesn’t seem normal.
    Shut the air passage near where it enters your throat? I think that’s normal.

    Do you, by any chance, have slight trouble breathing with a light cold, get a clogged nose easily or even have reduced sense of smell?

    Because I do and I can also do what you describe.

      Absolutely! The moment i catch ANYTHING remotely affecting the mucous in my nose everything is sealed shut tight. Regarding the reduced sense of smell i haven’t noticed anything.

    Yes, closing your sinuses is a natural reflex response for humans, and people have greater or lesser at will control over it.

    The nose holding for swimming is more about how strong that sinus closure is and endurance. People with larger sinus openings have a more difficult time keeping them closed and resisting pressure like water entering from jumping into a pool. Also some people have a hard time keeping them closed for any prolonged period.

    In other words, you just have totally ripped sinuses breh.

    My great grandma used to say, “I’d rather smell the smell than taste the smell!”

    Yes you can, but it’s not very strong. So when jumping into water, you might want to force close with fingers to prevent pressured water to get into the nose even if you keep it closed with your internal muscles.

    I almost broke my timpanus due to a very high jump without using the fingers

    How else do people blow out birthday candles, and blow up balloons? The air could just escape through the nose!

    I think with diving and other situations is to prevent the exposure of the inside of the nose. Especially when jumping in the water and and pressure can be much higher.

      From what i know, there are two ways to close your nose. one is via the soft palate. probably everyone can do that.

      the other is via the musculis nasalis, which op probably meant. most people can’t do that.

    I can’t do that. I never felt the need to hold my nose in any of the scenarios you described. I am pretty sure when it comes to your nasal cavities there are no muscles involved.

      Try blowing out a candle. Feel how your nose feels while doing that. Try to replicate the same movement in your nose without blowing.

      There’s a ton of face muscles that you can learn to control with a bit of practice:

      • Wiggling your ears
      • Moving your eyes inwards
      • Clicking your ear channels (like the click you hear when swallowing)
      • Creating a humming noise in your ears by flexing a muscle inside your ear channels
      • Plugging your nose from the inside
      • Rolling your tounge
      • Individual motion of your brows
      • “Vibrating” your eyes super fast left and right

      Probably a few more that I didn’t think of right now.

          Basically what happens when you look at your nose. But it’s also possible to e.g. only move one inwards while keeping the other straight. It’s not difficult, but there are people who can’t do it.

        Blowing out candles is controlling your nasopharynx which every does so food and liquids don’t go up their nose while swallowing. Most everyone can breathe through their mouth instead of their nose.

        The OP seems to be describing his nasal passage, not his throat. That seems unusual but I’ve never asked people to know.

          At least not in my case. If I blow out a candle, my nose passage closes.

          Maybe try the following:

          • Start with the motion of blowing out a candle.
          • While doing so, close your mouth, so that no air escapes through your mouth or nose, still holding the pressure of blowing.
          • Release your nose and feel the air popping out right at your nose.

          It’s not the bottom end of the nose, but the top end of it. It’s certainly not the laryinx, at least not for me.

            I just tried that and I can definitely say the closure happens at the pharynx for me, which is also what I do consciously when I hold my breath.

              Strange. Ok, can you make a snorting sound at the front of your nose? If you can, try to make a knocking sound with your nose. For that, build up pressure inside your nose using your tongue and release the sound by opening your nose.

              It’s similar to what you do when you have to sneeze and try to suppress it.

          Might be, but all of these are things I was not able to do at some point and that I conciously learned. So while having the “wrong” genetics might preclude you from doing them, you still need to learn these things if you have the “right” genetics.

    Yes I can stop myself from sneezing without holding my nose. But I’ve heard it’s bad for you. Some people cannot do it, and are surprised when I do.
