James Nestor is the perfect guide to the pulmonary world and has written a fascinating book, full of dazzling revelations'Dr Rangan Chatterjee, author of Feel Better in Five A fascinating scientific, cultural, spiritual and evolutionary history of the way humans breathe - and how we've all been doing it … Humans have forgotten how to breathe correctly, so the journalist James Nestor traveled the world to find out where we went wrong. James Nestor, a self-styled ‘aeronaut’ as he calls those who have deeply studied breathwork, and sought to educate and help others to breathe well, explores, clearly, so clearly, a whole range of extraordinary breathing techniques. In his new book, "Breath: The New Science of a Lost Art," Nestor tells the tale of exploring secret Soviet facilities, the smoggy streets of São Paulo and beyond, to learn the hidden science behind powerful ancient breathing practices. James Nestor's book, DEEP: Freediving, Renegade Science, and What The Ocean Tells Us About Ourselves (Houghton Mifflin Harcourt), was released in the United States and UK in June 2014.
