The Power of When

Outline

The Power of When (2016) shows that the timing of our daily activities matters as much as what we do. Michael Breus explains four chronotypes, the bear, lion, wolf, and dolphin, each with its own natural rhythm for sleep and energy. He helps readers identify their type and find the best times to wake, work, exercise, eat, and make important decisions.

• When you do something matters as much as what you do, and that applies to sleep, meals, work, and exercise.
• Breus describes four chronotypes, the bear, lion, wolf, and dolphin, each with its own natural rhythm of sleep and energy.
• Your first step is to identify which chronotype you are, since your best daily schedule follows from it.
• Knowing your type helps you choose the best times to wake, work, exercise, and eat.
• Important decisions are also better made at the right time of day for your biological clock.
