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…
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.
