After eliminating the causative factors, the prognosis is usually better.1.

Before going to sleep, they should not drink drinks that can excite the nerves, such as strong tea and coffee, to avoid insomnia. 2. Behavioral adjustment: Bad habits such as playing with cell phones and computers before going to bed can excite the cerebral cortex, which in turn leads to insomnia and poor sleep quality. After lying down in bed, patients should close their eyes to rest their mind and avoid ruminating. In addition, regular rest, avoid staying up late and other methods also have a role in relieving insomnia and improving sleep quality; 3, environmental changes: sleep space brightness is too high, the sound is too noisy and other factors can lead to insomnia and dreamy patients. Patients should rest in a comfortable, dark, quiet space to avoid the adverse effects of the outside world; 4, moderate exercise: moderate exercise can increase the body’s deep sleep time. Patients can, according to their own situation, aerobic exercise, such as walking, climbing, etc., and try to avoid strenuous exercise before going to bed at night; 5, drug treatment: If patients have serious symptoms, they can be treated with oral drugs under the guidance of professional doctors, such as zolpidem tartrate tablets, dexrazopiclone, etc. Although the drugs have a sedative effect to help sleep, but can not be taken for a long time to avoid drug dependence.
