First, avoid greasy feeling and prevent human fat from depositing in the liver. In winter, when the temperature is low, the necessary heat energy of the body increases and the appetite increases. In order to better resist the erosion of cold environment, we usually eat some high-fat and high-calorie food ingredients, such as various meat foods. And winter is also a good case of food supplement, and some families will stew some nutrients at this time. Human fat and protein have become the main characters of many people's winter diets, but these nutrients can't be used by the body after being digested and absorbed. It must be metabolized in the liver and then transmitted to every organ and institution of the human body with blood. Excessive intake can cause mild fatty liver and even lead to decreased liver function.

Second, avoid drinking alcohol to prevent alcohol from damaging the liver. Drinking alcohol is harmful to physical and mental health. It is a truth that everyone knows. From the doctor's point of view, it is best not to drink alcohol. This is because 90% of alcohol is metabolized in the liver, and the liver function of patients with hepatitis and mild fatty liver is damaged. Drinking alcohol is equivalent to adding fuel to the fire, which will aggravate the damage to liver cells. Therefore, for some patients with liver diseases, it is necessary to quit smoking and drinking. For some people who can't quit smoking and drinking, they also need to be careful not to drink too much and not to "continuously" injure their liver. According to the data survey, the incidence of alcoholic mild fatty liver, alcoholic hepatitis and alcoholic cirrhosis ascites were 50%, 10% and 10% respectively.

Third, avoid staying up late often and be alert to abnormal liver function. Rest and sleep are very important for the physical and mental health of the liver. In winter, the days are short and the nights are long. Many people like to stay up late often, which is the easiest way to damage the liver. Some people often stay up late and find that alanine aminotransferase rises the next day, which is also a sign of abnormal liver function. Chinese medicine believes that human qi and blood are weak in winter, and the period from midnight to zero in the morning is also the weakest and coldest period of the day. If you don't sleep at this time, it is very easy to cause the invasion of dampness.

Fourth, avoid depression and prevent stagnation of liver qi. The prevalence of depression in winter is very high, which is related to festivals. Because the days are short and the nights are long, the sunshine time is relatively reduced and the compressive strength of the sun is low. The secretion of thyroid hormone and adrenaline in the body will be reduced, and people's emotions will be more vigorous, and they will always feel very tired, have negative emotions, improve their sleep quality and be agitated. Traditional Chinese medicine says that "the liver governs emotions", and a bad attitude will lead to stagnation of liver qi and endanger the function of the liver. In particular, getting angry will seriously affect liver function, which is the most taboo mentality for health care.
