Solution: Pay attention to the humidity and temperature of the bedroom, as well as noise and murmur. Don't eat greasy food before going to bed, but be full. Stretch your muscles properly before going to bed and twist your whole body. 1/kloc-0 go to bed before/:00 (because you are a high school student, you have to get up before 7:00).
When you come home from school, beat the ground with the forefoot of your foot, stamp the ground, and stimulate the peripheral nerves: or soak your feet with hot water and massage the soles of your feet.
If you can't sleep, don't play with your mobile phone, avoid bright screens and fluorescent lights, read a book and listen to an intoxicating love song.
The feng shui layout of the bedroom is very important, and poor sleep is a taboo for high school students. Daily memory is determined by the quality of sleep.
Don't point the mirror at the bed, don't see the bed when you open the door, and don't point the end of the bed at the door. Maybe draw a screen and curtains to block it.
The bedroom space should not be too big. Don't hang wet clothes in the bedroom, blow your head and eat instant noodles in the bedroom (humidity problem).
The floor of the bedroom should not be too bright, generally with dark tones, and the curtains should be well shaded. After waking up, you can open the curtains and look at the bedside position of the sun. You can wake up all day.
note:
Don't eat sweets before going to bed. Sweet food will soften the skull, block the circulation of cerebral arteries and slow down the metabolism of brain cells.
It's best to supplement protein's intake, add an egg to boiling water, crush it and cook it. Lecithin is good for the brain, and protein repairs damaged cells in the body.
