Drink honey in the morning to prevent constipation and nourish the skin. But be careful not to drink honey water on an empty stomach. Drink warm water first, then honey water. Drink a glass of honey water before going to bed every night. Honey is rich in magnesium. Magnesium has a sedative effect on the central nervous system of the brain, which can regulate psychology, eliminate tension and relieve stress, so it can soothe the nerves and help sleep.
