The power of your physiology can be harnessed in two complementary ways: First, through a set of foundational behaviors—core practices that substantially improve your day-to-day mental and physical state. Huberman offers essential practices for both, called “protocols.” These protocols can help you unlock your brain and body’s full potential across seven areas: - Sleep - Exercise - Stress Control - Nutrition - Light - Focus, Motivation, and Learning - Personal Growth For example, a simple sleep protocol includes viewing sunlight as soon as possible after waking. Second, through specific science-based tools you can use to overcome common challenges or achieve elevated levels of mental or physical performance.
