Benefits: prevent constipation, nourish skin and prolong life. Disadvantages: Drinking honey water on an empty stomach can easily increase the acidity in the body, which will lead to gastric ulcer or duodenal ulcer for a long time. It is recommended to drink honey water after meals 1.5-2 hours. Note: It is best for people with a bad stomach to drink 30-degree water, otherwise it will easily lead to diarrhea, gastroenteritis and other traditional Chinese medicine sayings: "Salt water in the morning, at night." It means: get up early every day and drink light salt water on an empty stomach, and drink honey water every night before going to bed. The reason for this is that drinking light salt water in the morning can dilute the blood that feels very sticky, and has a little anti-inflammatory, stomach-moistening and laxative effects; Drinking honey water at night is helpful for beauty and supplementing various trace elements. Therefore, it is more scientific to leave honey water to drink at night and get up in the morning to drink light salt water. Of course, some people have difficulty defecating, so drinking honey water early will help defecate, or it depends on their physical condition. My personal recommendation is to drink a cup of hot milk with a spoonful of honey before going to bed every night. Because milk contains more potassium, honey is rich in magnesium. Studies have shown that potassium plays an important role in the conduction of nerve impulses and the coagulation of blood. It can relieve mood, inhibit pain, prevent infection and reduce menstrual blood loss. Magnesium has a sedative effect on the central nervous system of the brain, which can regulate psychology, eliminate tension and reduce stress. So it is very helpful for women. In addition, milk and honey are rich in B vitamins, which can relieve sleep. Honey also has the function of moistening skin and whitening skin. Because honey is rich in nutrients, it is easy to be absorbed and utilized by the human body, and it has a moisturizing effect on the skin. Especially when the climate is dry in winter, eating more honey can prevent chapped skin. Many advanced cosmetics are extracted from honey, which shows that honey has a good protective effect on the skin. If it can be taken orally and externally for a long time, it will help to beautify and prolong life.
