What Happens When You Quit Mouth Breathing?
Shut your mouth to save your health. Better oxygen, sleep, and jawline.
Quick Summary
Nose breathing produces Nitric Oxide, a vasodilator that increases oxygen absorption by ~18%. Quitting mouth breathing filters the air, warms it, and drastically improves sleep quality (snoring often stops). Long term, it can even change facial structure (mewing concept).
