The legendary "emptiness leads to compulsion". Because your brain is often empty before going to bed, you need to find something to do. If you do something for a long time, it will become a habit. Before going to bed, forcing yourself to do it is winding. Experts believe that it takes 2 1 day to form a habit. You can try to do something else before going to bed for 265,438+0 days, and you will find that you only need to do something before going to bed, and the content is just a habit. But personally, this habit is not recommended.
