In his brilliantly researched book Breathe: The New Science of a Lost Art, journalist James Nestor sets out to explain how we've forgotten to breathe correctly in modern times. He travels the world to rediscover the long-forgotten truth about breathing, subjecting himself to a number of ancient and modern breathing techniques. The result is a masterclass in how breathing can help you feel both calmer and more energized. I interviewed James in 2020, shortly after his book was released. It would go on to become an international bestseller.
