To change your life, you have to change your mind-and you can! Your brain cells have the power to build new pathways that will reinforce what you learn, including better health habits. This power is called neuroplasticity. Electrical impulses travel through your brain cells, carrying information that enables your every thought and action. Some of your most often-repeated actions are almost automatic, because the neurons involved have fired together so many times, they have formed something like a shortcut. When you learn a new procedure or behavior, including a better health habit, different neurons will connect to carry that information and trigger a new response. Learn how brain activity can change as a result of our actions.
