Why We Sleep

Unlocking the Power of Sleep and Dreams

by Matthew Walker PhD

Matthew Walker is one of the world’s leading neuroscientists and sleep experts. He’s a professor at UC Berkeley (and former professor at Harvard) who has spent decades studying why we sleep and how to, as per the sub-title of this book, unlock the power of sleep and dreams. As you know if you’ve been following along, I’m a HUGE advocate of Optimizing our sleep as a fundamental practice in Optimizing our lives. This book has made me EVEN MORE bullish about the power of sleep. The consequences of chronically depriving ourselves of the sleep we need? Well, they’re astonishingly devastating—dramatically increasing the odds of having everything from mood disorders to cancer (and everything else we don’t want). Big Ideas we explore include the fact that you're more likely to get struck by lightning than have the gene that let's you get by on less than the recommended sleep, the universality of sleep (even worms sleep!!), resetting baselines, the iPad effect (did you know how much using one before sleep messes w/your melatonin?), and some tips to Optimize your sleep TONIGHT!!!
