First: various bedtime activities.
Personally, I like to take a hot bath before going to bed, because I am exhausted after a day's work. I take a hot bath, get into bed and fall asleep with my eyes closed. If you don't have time to take a bath, then I suggest you take a hot bath, which is also good for sleep and a small way to keep fit. You can also drink a glass of milk before going to bed.
Second: study before going to bed.
Learning itself is a very boring thing. Everyone should remember that many people will fall asleep in math class when they are studying. The math teacher's teaching is simply a hypnotic spell. I can't read the blackboard at all, so it's normal to feel sleepy. Choose a course that you find the most boring, and force yourself to learn and absorb before going to bed to ensure that you can fall asleep quickly.
Third: take medicine and listen to music.
If your insomnia is really serious, please remember to take appropriate medicine, which can help solve your sleep problem in a short time. Play some soothing music when you sleep. Music that helps you sleep can also make you fall asleep quickly. Everyone falls asleep in different places, so choose the music type according to their own understanding.
In addition, I suggest that you can order incense, lavender incense, which can effectively help you sleep ~
