Sleep is literally the most important thing you can do to affect every aspect of your existence, and you can drastically improve your life (for free) by improving to how you sleep. Jeff Kahn is CEO and co-founder of Rise Science, the only app that delivers the real-world benefits of better sleep and daily energy. We talk about why sleep cycles like REM don’t matter. DON’T matter. We talk about the real world job performance of NFL teams (look up Monday night football stats), why sleep debt and circadian rhythm are actually the key factors, rest & recovery, the history or sleep science, and why it’s more important than diet, exercise, meditation, or anything else you can think of. Good Night!
