"The Power of When prepares you to take full advantage of our adaptation to the rhythms of nature. After reading this book, your decision-making ability will forever be improved. This is a new horizon in our understanding of human behavior, and Michael Breus masterfully presents the science as a recipe for self-improvement."

Whether you're looking to improve your relationships, get a raise at work, or simply lead a more fulfilling life, THE POWER OF WHEN is the guidebook you've been waiting for."―Mark Hyman, MD, Director, Cleveland Clinic Center for Functional Medicine
