Thank you! I saw you mentioned mewing in your comment, they teach you that in some pranayama exercises as well and I agree it’s a great addition. It feels unnatural at first but when you get used to it, it’s almost like bracing your palate with your tongue allows you to pull air in through your nose more smoothly and with more power.
I’ve found this is all really worth learning, even if you don’t have sleep apnea. I feel more clear headed and energized when I can breath through my nose now.
That's fascinating, I just did some reading on this - I had not known that the basic technique of "mewing" is very similar if not identical to something that's been practiced in yoga for thousands of years. That in itself doesn't speak to its effectiveness necessarily but on the surface it's a different way to look at it than as just a modern fad.
Regardless, it doesn't cost anything to try, seems no danger in it and it seems logical that it could help.
