The Power of When by Michael Breus, PhD is a popular science and self-help book centered on chronobiology, the study of how the body’s internal clock influences sleep, energy, focus, mood, and performance. Rather than treating everyone as if they should follow the same daily routine, Breus argues that people have different chronotypes, or biologically rooted timing patterns, that shape when they are naturally most alert or most in need of rest. The book introduces four main chronotypes: Lion, Bear, Wolf, and Dolphin, and uses them as a framework for deciding when to schedule work, exercise, meals, social interaction, and even health-related tasks. Its purpose is practical: to help readers stop fighting their natural rhythms and instead organize the day around them. The book combines scientific research with scheduling advice, making it especially relevant to readers interested in sleep optimization, productivity, and routine design.
