Is it normal that i only breathe through one nostril at a time?
I noticed a few years ago that I only breathe out one nostril at a time. I'm not sure if its the same with breathing in and I'm not sure if this is how its always been. And I go from only breathing through my left nostril to only breathing through my right nostril and back again. Do most people only breathe through one nostril at a time because I went most of my life without noticing this. And I'm 18 years old.
