Insomnia generally cannot be treated by food regimen, it needs to be treated by behavioral therapy to improve the symptoms and, if necessary, medication can be used. 1. Behavioral treatment: It is very helpful to improve mild to moderate insomnia. First of all, do not be anxious because of insomnia, and avoid excessive attention to insomnia. Do not go to bed easily without sleepiness. If lying in bed, do not do things not related to sleep, such as watching TV, playing games, making phone calls and so on. Also don’t sleep more than half an hour during the day, or try not to nap, so that you can leave the best sleep time at night. Avoid strenuous exercise before going to bed, as well as strong tea, strong coffee, or intense thought activities. 2. Medication: If you can’t improve your insomnia after behavioral therapy, you can take diazepam tablets and other medications orally as prescribed by your doctor. If the insomnia is serious, it is recommended to go to the hospital in time and follow the doctor’s instructions for treatment.
