Generally speaking drinking alcohol is not able to improve sleep, although there are patients who have been drinking for a long time, it is easy to fall asleep quickly after drinking, but it is difficult to maintain a long and high quality sleep, easy to wake up early and easy to wake up. After drinking alcohol, it is easy for patients to enter light sleep, but it is difficult to enter deep sleep. The body mainly restores physical strength and stores memory during the deep sleep period, and if there is alcohol dependence, it is possible that insomnia can easily occur without alcohol, and it is recommended that the intake of alcohol can be slowly reduced until the alcohol is completely quitted. To have good sleep quality, establish good sleep hygiene habits and try not to read books, newspapers, cell phones, TV or games in bed until you have the desire to sleep and then go to bed. If you do not fall asleep after lying in bed for 30 minutes, it is recommended to get up immediately and go to other rooms to do housework or read books and do boring, tedious things until the patient has the desire to sleep before going to bed. No matter what time the patient went to sleep the day before, the patient should get up within a fixed time the next day, and try not to nap or nap during the day, so that the sleepiness will easily occur at night, which can improve the quality of the patient’s night sleep.
