Mewing, 2021 update

[Josh]

Whats the deal with mewing? It doesn’t seem like much an investment, but does it have any negatives?

Anyone here tried it and experienced negative effects from doing it ?

Tips on how to ensure you are doing it correctly?

I actually have a decent jaw line since taking my test from 3 to 28 and fixing some other issues, but it seems this mewing technique also benefits other things like sleep apnea, breathing through the nose more than the mouth etc. (I do wake up now and again with this stuffy nose which means I’m breathing through my mouth).

I can testify that the correct posture of your tongue does affect your breathing at night. Mouth taping during nights (put the tape on while you have put your tongue ok your palate) helps acutely and is most effective in my experience.
Unfortunately can’t say much about mewing but maybe this helps you a little.
