Power Of When

Learn the best time to do everything -- from drink your coffee to have sex or go for a run -- according to your body's chronotype.

Most advice centers on what to do, or how to do it, and ignores the when of success. But exciting new research proves there is a right time to do just about everything, based on our biology and hormones.

As Dr. Michael Breus proves in The Power Of When, working with your body's inner clock for maximum health, happiness, and productivity is easy, exciting, and fun. The Power Of When presents a groundbreaking program for getting back in sync with your natural rhythm by making minor changes to your daily routine.

After you've taken Dr. Breus's comprehensive Bio-Time Quiz to figure out your chronotype (are you a Bear, Lion, Dolphin or Wolf?), you'll find out the best time to do over 50 different activities. Featuring a foreword by Mehmet C. Oz, MD, and packed with fascinating facts, fun personality quizzes, and easy-to-follow guidelines, The Power Of When is the ultimate "lifehack" to help you achieve your goals.
