This is a fantastic 30 min podcast on NPR. James Nestor has been studying breathwork in an unbias and analytical manner and made some incredible discoveries.
Some things the podcast confirmed is that nose breathing, while you sleep, makes a huge difference in sleep quality. I trained myself to do it about a month ago. I never thought I could do it, but I found tape to open my nostrils while using mouth tape with a small breathing slit. It took less than a full supply of each, and now it happens naturally most nights.
Some things I learned is that your nose gets engorged with blood at certain times of the day, even on just one side, that restricts airflow. I always thought it was mucus and it was a problem. Also, I learned, breathing through both nostrils might create a sense of balance or harmony in your body.
