I tried the Buteyko method about 10 years back.. I wouldn't believe any of the theories of action, but the method worked to nose breathe and have tolerable sinuses.

One observation from Buteyko materials that sounds right (and would be easy to verify) is that only one nostril should be active when you aren't exercising, and there is a ~3? hour cycle where they swap dilation repeatedly through the day and night. When you are healthy you won't notice this (unless someone asks you to gently test), if you panic and fight to keep them both open, it will cause you more trouble.

It’s called the nasal cycle.
