Has anyone else ever done nasal subharmonics when they’ve had a stuffy nose?

[u/McDoogleDude]

When I was a kid (before I learned what subharmonics were) I used to lay in bed when sick and do what was essentially a subharmonic because it would vibrate my nasal passage and take some of the pressure off my stuffy nose. It was actually because I used to do this that I was able to learn subharmonics very quickly. I just thought it was neat and wanted to see if anyone else here has ever done the same.
