Neuroplasticity is a fancy name for brain change. Every time you engage in a new habit you change your brain. Habits, therefore, can change the physical structure of your brain, making it better and more efficient. Every new habit improves your brain. The more habits you have, the more efficient your brain becomes. Habits are important because they reduce the consumption of glucose (brain fuel). The brain is an energy hog. It uses 20% of the entire body’s glucose reserves. If you are running low on glucose reserves, your brain slows down and your thinking is impaired. Habits prevent this from happening. When you add a habit, you actually reduce the brain’s need for glucose, which lowers the demand for glucose, making your brain work better and this improves your ability to think.
