Yup totally, how you breathe during the day is a habit that basically persists at night

So breathing better during the day can be trained, even at an old age, and it improves sleep

Not everyone breathes suboptimally of course, but I think more do than realize it. There’s a reason that breath work is in the traditions of many different cultures, and why it survived

But things like this aren’t necessarily profitable or worth a doctor’s time, so you have to do them yourself, or see therapists, etc

I had a good experience with a myofunctional therapist and posture therapist
