Arianna Huffington, one of the most influential women in the world, was falling apart at work because she was – literally – exhausted. This week she shares her inspirational wake-up call with us. Her book, The Sleep Revolution, is based on science-based secrets that can help us all sleep our way to success. Arianna says lack of sleep costs the U.S. economy $63 billion a year, and no surprise, it’s more of a problem for women! Of course, we all sleep more soundly when we are not worried about money, our family, our jobs or our relationships. But, Arianna says, we need to think of that problem in reverse. Being well rested is the key to regaining control.
