If you want to understand sleep deprivation, you want to talk to a member of the Navy SEALs, who go nearly a week without rest during training. And there’s probably no better Navy SEAL to talk to than Kirk Parsley, the physician who started noticing all sorts of problems with his fellow elite soldiers. They weren’t recovering from workouts, they had trouble concentrating, and they were emotionally unstable. The culprit: they weren’t getting enough zzz’s. After a decade studying the benefits of sleep, Parsley says that getting enough rest at night is the single most effective performance-enhancing habit. Miss two hours of sleep and he can tell. Here, he goes beyond the eight-hour rule to talk specifically about how shuteye makes you faster, stronger, and smarter, and how sleep aids can actually do more harm than good.

Outside’s longstanding literary storytelling tradition comes to life in audio with features that will both entertain and inform listeners. We launched in March 2016 with our first series, Science of Survival, which was developed in partnership with PRX, distributors of the idolized This American Life and The Moth Radio Hour, among others. We have since expanded our show and now offer a range of story formats, including interviews with the biggest figures in sports, adventure, and politics, as well as reports from our correspondents in the field.
