Everyone can flare their nostrils, and they can close the nasal passages when in the water. So we have some control of muscles in that area. The good news is that the muscles continue up into the sinuses, but we haven't learned to use them yet.
So here's the trick: Flare your nostrils, then visualize flaring them up a bit higher. Do this several times a day and you will begin to have control over those unused muscles. Every day you will be able to open the passages a bit higher up. It only took about a week before I was breathing freely through my nose. Try it.
