Develop good sleep habits and do the following: 1. Don't sleep too long: oversleeping will disturb your personal biological clock. Besides, it will make it harder for you to try to fall asleep quickly. 2. Take a hot bath: Taking a hot bath can relax your body. 3. Exercise at the right time: Make an exercise plan and pay special attention to increasing aerobic exercise! If you are tired during the day, you will sleep faster at night. The time and intensity of exercise are very important, otherwise the effect will be self-defeating. 4. Stay away from alcohol, caffeine and all kinds of spicy food before going to bed: Caffeine can lead to excessive excitement and insomnia. Spicy food will stimulate the brain and keep it awake. Alcohol can disturb sleep by interfering with sleep stages. 5. Comfortable sleeping environment: keep the room moderately refreshing. However, it should be noted that excessive humidity may also affect sleep. Using fans or background music helps to relax and promote sleep. 6. Relax in the evening and don't worry about the unfinished tense affairs. 7. Don't watch TV or play mobile phone in bed. This may alert you, because your brain will decide that your bedtime is watching TV and playing mobile phone instead of sleeping.
