Keep a sleep routine（常规）．Going to bed at the same time every night helps the body expect sleep．Creating a set bedtime routine can improve this relaxation effect．Spending time with a pet，writing a diary or doing anything else can relax you．
Expect a good night's sleep．Instead of worrying that you won't sleep，remind（提醒） yourself that you can．Say"Tonight，I will sleep well"several times during the day．It can also help to practice breathing exercises or gentle exercises before bed．
