What if the way you breathe is quietly wrecking your sleep, focus, energy, and long-term health? In this episode, Sean Kelly sits down with James Nestor to break down why so many people are breathing the wrong way without even realizing it. They get into mouth breathing, snoring, braces, sleep apnea, carbon dioxide tolerance, indoor air quality, and why poor breathing may be affecting way more than just your lungs. James explains how modern life changed the way we breathe, why so many people now have smaller airways, and how something as simple as nasal breathing could improve sleep, performance, focus, and recovery. He also shares why elite athletes train their breath, why indoor air can crush cognitive performance, and why “normal” habits like snoring are actually major warning signs. This episode is a wake-up call for anyone who wants better health, better energy, and better performance. James Nestor is the bestselling author of Breath and one of the leading voices on how breathing impacts the body and mind.
