This is a very common problem that many people have trouble falling asleep at night. There were many reasons for this situation, including psychological and physiological factors. Here are some suggestions that might help improve your sleep: 1. Set up a regular sleep schedule: Go to bed and wake up at the same time every day, even on weekends. It helps the body establish a normal sleep rhythm. Create a comfortable sleeping environment: Make sure the room is quiet, dark, cool and comfortable and use comfortable mattresses and pillows. 3. Avoiding stimulating substances: avoid drinking coffee, tea, and soda drinks that contain coffee and stimulating substances. At the same time, avoid smoking and drinking harmful substances. 4. Relax your body and mind: Doing some relaxing activities before going to bed such as meditation, deep breathing, or listening to soft music can help reduce stress and anxiety and promote relaxation and sleep. 5, avoid using electronic devices: Try to avoid using electronic devices such as mobile phones, computers, and televisions before going to bed because these devices will emit blue light and interfere with the body's secretion of melonin, thus affecting sleep. If the above suggestions cannot alleviate your problem, it is recommended to consult a doctor or professional psychologist.
