That’s why it’s so alarming that most of us are doing it wrong. Today on The Doctor’s Farmacy, I talk all about the science and evolution of how we breathe, and how to get better at it, with James Nestor. James Nestor is an author and journalist who has written for Scientific American, Outside, The New York Times, and more. His latest book, Breath: The New Science of a Lost Art, was an instant New York Times bestseller. Breath explores how the human species has lost the ability to breathe properly—and how to get it back. James has appeared on dozens of national television shows, including ABC’s Nightline and CBS’s Morning News, and on NPR. He lives and breathes in San Francisco.This episode is brought to you by Rupa Health, BiOptimizers, and InsideTracker.Rupa Health is a place where Functional Medicine practitioners can access more than 2,000 specialty lab tests from over 20 labs.
