The liver is the largest substantial organ in the body, occupying the right rib cage and the greater part of the supra-abdominal region of the abdomen. The liver is also the largest digestive and immune organ in the body, and performs a variety of tasks in the digestive and immune systems. However, because of the fast pace of modern life, many people are suffering from various liver diseases. What should we do to protect our liver to keep it from harm? 1, drinking too much alcohol. The term “alcohol hurts” is familiar to everyone, but in today’s society, drinking has become a “trend”, a means of business talk, drinking alcohol hurts, but is ignored by people. Epidemiological surveys have shown that long-term heavy drinking is not only harmful to the liver, but may also be associated with the development of liver cancer. Alcohol consumption has a significant and independent effect on the occurrence of liver cancer, and shows a significant dose-effect relationship. It is generally believed that excessive alcohol consumption often leads to liver cancer through the steps of fatty liver, alcoholic hepatitis and hepatic steatosis. Liver cancer occurs in 10%-30% of alcoholic liver steatosis. 2. Staying up late and overworking. Nowadays, people work overtime and stay up late, which has become a daily routine. Young people feel that staying up late is not a big deal because they are young, but they do not know how much harm is hidden behind staying up late. According to Chinese medicine, every night from 23:00 to 2:00 a.m., the liver begins to detoxify, and is also the best time to nourish the liver and blood, but liver detoxification needs to be carried out in deep sleep. Staying up late does not allow the liver to carry out detoxification and cannot convert new blood, and in the long run, not only does the body feel tired, but the detoxification function of the liver will also be damaged. 3, negative emotions. In Chinese medicine, “anger hurts the liver”, if long-term depression and anger, can lead to liver qi stagnation, causing physiological disorders. In outpatient clinics, we often hear patients or family members complain that they (the patient) have a lot of temper after having liver disease and get angry at every turn. A physiologist in the United States, Alma, once did a “gas water” experiment, he found that when people are calm, exhaled condensed gas water, clear and colorless, without impurities, but when angry, but there are purple precipitates. When he injected the “angry water” into rats, the rats died of convulsions within a few minutes. This experiment shows that when people are angry, they are actually secreting toxins. Anger can cause a dramatic increase in the number of red blood cells in the body, blood clotting faster than normal, easily causing tachycardia. This will not only damage the cardiovascular system, but will also affect the health of the liver. 4, take drugs indiscriminately. Since ancient times, there is “medicine three points of poison”, many drugs, more or less to the liver are toxic, some drug toxins will be transported to the whole body with the blood, causing the body’s cells to die in large numbers, thus destroying the body’s immunity. Although the liver’s main function is to detoxify, but if we often take drugs indiscriminately, it will inevitably cause a large accumulation of toxins in the body, thus causing an increased burden on the liver, in the long run, the liver will be overwhelmed, resulting in liver function decompensation and further loss of detoxification function. 5, the intake of too much greasy food. Fat is one of the necessary nutrients for the human body, the right amount of fat can supply us with energy to maintain the normal physiological functions of the body. However, the intake of too much fat can cause excessive fat accumulation in liver cells, inducing lesions and forming a fatty liver. Fatty liver will bring what kind of harm to the body, I think we all know very well, I will not describe here. 6.Damage from toxic substances. It is relatively rare, but there are also liver damage caused by pesticides, rat poison, toxic gas, poisonous mushrooms, etc. Therefore, do not just eat some unknown mushrooms, especially do not be confused by some “beautiful” mushrooms, but also to prevent the family of children and other misuse of agricultural (rat) drugs, to avoid unnecessary liver damage. The above mentioned are some of the bad habits and other factors that can damage our liver. In order to protect our health and to prevent the disease before it happens, we should start from these small details of life and improve our immunity so that the virus will not take advantage of the situation and cause more damage to our body.
