Breath

James Nestor is the journalist who discovered modern humans forgot how to breathe, transforming health through ancient breathing techniques.

San Francisco-based journalist whose decade-long breathing investigation produced Breath, selling 2+ million copies and topping bestseller lists globally. His Stanford experiment proved mouth breathing damages health within days. Writing appeared in Scientific American, New York Times, and Outside Magazine. Previous book Deep explored freediving's extreme physiology. Taught breathing techniques to Google, UN, and medical schools. TED Talk exceeded 5 million views.

What sets Nestor apart: He suffered every breathing experiment personally, from mouth-taping to holotropic breathwork, validating through experience.

Practitioners of Nestor's breathing techniques report 50% improvement in sleep quality and athletic performance.

The investigator who proved the best medicine requires no prescription—just different breathing.
