The New Science Of Breath: James Nestor On Why Most People Are Breathing Wrong

The Rich Roll Podcast

James Nestor is an acclaimed science journalist and author of the international bestseller "Breath: The New Science of a Lost Art."

This conversation explores why so many of us breathe dysfunctionally—and how it may be connected to chronic ailments. We discuss breathing biomechanics, CO2 tolerance, the link between sleep-disordered breathing and ADHD in children, and practical techniques to optimize how you breathe.

James also walks us through his Stanford experiment, where breathing only through his mouth precipitated sleep apnea within ten days, which completely reversed in 48 hours with nasal breathing.

This one is packed with actionable tools you can implement immediately. Enjoy!
