Is mouth taping actually safe? And does nose breathing really improve sleep? In this episode, I break down key insights from Mollie Eastman’s interview with breathing expert Patrick McKeown on Sleep As a Skill. We cover why waking up with a dry mouth is a red flag, how nasal breathing supports airway stability, the difference between full-seal and vented mouth tape, and who should avoid taping altogether. Plus, I share practical daytime nose-breathing habits—like walking with your mouth closed—to make nighttime breathing easier and more natural.
