There is a red nightlight in the room. Many people are used to watching mobile phones, tablets, computers or TV before going to bed. The blue light emitted by the screens of these devices will inhibit the secretion of melatonin in the brain, disturb the biological clock, and cause the brain to be extremely excited. If you are still excited and awake after lying in bed for half an hour, you can put a red nightlight in your bedroom, put down your cell phone and close your eyes half an hour before going to bed. I believe you will fall asleep soon. As long as you persist for a period of time, the biological clock will return to normal.
Wipe your hands and face with cold water half an hour before going to bed. Lying in a bed with poor ventilation in the bedroom will make you very upset and difficult to sleep. You can wipe your face and hands with a cool towel to lower your body temperature as soon as possible and help you sleep.
