Poor sleep quality may be caused by many factors, such as emotional factors, drug factors, age factors, diet factors, disease factors and so on.

1. Put the bed where the bed is. In life, many people will read books and watch their mobile phones in bed. These habits will cause the brain not to regard the bed as a place to sleep, so that it can't fall asleep smoothly during sleep.

2. Drink too much milk, and some people try to make themselves fall asleep smoothly. Drinking milk to treat sleep is not good, but drinking too much will lead to physical discomfort, which in turn will lead to poor sleep.

3. Drinking, many people will drink all their lives. Drinking a small amount of wine will make people sleepy for a short time, but drinking for a while will make people feel excited.
