In her new book, Arianna Huffington, the co-founder and editor-in-chief of The Huffington Post, and the author of the #1 New York Times bestseller Thrive delves into the sleep revolution that is happening all across the world - a revolution that can transform our lives. Sleep, she writes, is one of humanity's great unifiers, binding us to each other, to our ancestors, to our past, and to the future. Yet we find ourselves in the middle of a crisis of sleep deprivation, with devastating effects on our health, our happiness, our job performance, and our relationships. Only by renewing our relationship with sleep, she writes, can we take control of our lives, live more fully, be more engaged with ourselves and with the world, and more able to meet the inevitable challenges we all face.
