We finally know why it's so good for you (Level 1)

Many people think that "zoning out" or losing focus is bad. However, new science shows it might be essential for your health. Researchers studied people who did not sleep enough. They found that when these people lost focus, a special fluid moved through their brains. This fluid washes away waste and chemicals. This cleaning process usually happens when we are in deep sleep. If you are tired, your brain forces you to zone out to clean itself. Being bored can also be good for you. When you let your mind wander, you become more creative. Your brain solves problems in the background. This is difficult today because of smartphones. When we feel bored, we usually look at our phones immediately. This stops the brain from resting and thinking. Experts say we should put our phones away and let ourselves be bored sometimes. It helps the brain stay healthy and strong.
