1, the important principle of health preservation in winter is "tonifying kidney and preventing cold". Kidney is the motive force of human life. The kidneys are full of vitality, and the body can adapt to the changes in severe winter. The key to ensure kidney qi is to prevent the invasion of cold climate. 2, ◆ Cold weather in winter, cold stagnation, easy to lead to poor blood circulation, making many old diseases relapse or aggravate. Especially those serious life-threatening diseases, such as stroke, cerebral hemorrhage and myocardial infarction. Not only has the incidence increased significantly, but the mortality rate has also increased sharply. Therefore, winter health should pay attention to cold protection. ◆ In winter, the yang of human body gathers, qi and blood tend to flow inward, the skin is dense, and water and dampness are not easy to leak from the body surface. However, after the kidney and bladder are gasified, a small part of them become body fluid, which spreads all over the body, most of them differentiate into water, and the bladder becomes urine, which invisibly increases the burden on the kidney and easily leads to diseases such as nephritis, enuresis, urinary incontinence and edema. Therefore, winter health care should pay attention to the maintenance of kidneys. 3. Principles of Diet Conditioning Winter diet should follow the principles of "nourishing yin in autumn and winter", "tonifying kidney and preventing cold" and "worrying about Pingyang", and the diet should mainly nourish yin and suppress yang and increase calories. 【 Nourishing kidney first 】 Cold should be used for kidney. Kidney is the motive force of human life and the "innate foundation" of human body. In winter, the yang of the human body is suppressed, and the physiological activities of the human body also converge. At this time, the kidney should not only prepare enough energy to maintain the heat expenditure in winter, but also store some energy for the coming year, so it is very important to tonify the kidney at this time. In diet, we should always pay attention to the nursed back to health of the kidneys, pay attention to the supplement of calories, eat more animal foods and beans, and supplement vitamins and inorganic salts. Dog meat, mutton, goose, duck, soybean, walnut, chestnut, fungus, sesame, sweet potato and radish are all suitable foods in winter. [Warm food is hard to avoid] Sticky and cold food is mostly cloudy, and eating such food in winter is easy to damage the spleen and stomach. Moreover, food overheating is easy to damage the esophagus, and after entering the stomach, it is easy to cause heat accumulation in the body and cause diseases; If the food is too cold, it will easily stimulate the blood vessels in the spleen and stomach and make the blood flow poor. However, the decrease of blood volume will seriously affect the blood circulation of other organs and endanger human health. Therefore, the diet in winter should be gentle. In winter, the function of the kidney is stronger. If you eat more salty food, the kidney qi will be stronger, which will greatly hurt the heart, weaken the strength of the heart and affect human health. Therefore, eat less salty food in winter to prevent excessive kidney water; Eat more bitter food, nourish the heart and enhance kidney function. Commonly used foods are: betel nut, orange, pig liver, sheep liver, kohlrabi, lettuce, vinegar, tea and so on. Edit this daily life adjustment [sleep adjustment] The winter routine should be "going to bed early and getting up late", and it is best to get up after the sun comes out. Because going to bed early can maintain human yang and keep the body warm, while getting up late can nourish human yin. Do it at sunrise, get up and stop the cold, and ask for its warmth. Don't sleep with your head covered when it is warm. If the air in the bed is not circulating, there will be less and less oxygen. Over time, the air will become turbid. When people sleep in such an environment, they will feel chest tightness, nausea, or wake up from sleep with a cold sweat and feel tired the next day. [Cold-proof and three warmings] ◆ Keep the head warm When the head is cold, the blood vessels contract and the muscles in the head are tense, which may easily cause headaches, colds and even gastrointestinal discomfort. ◆ Stimulation of cold and warm back can affect local muscles or introduce internal organs through back acupoints, which is harmful to health. Cold in the back not only causes backache, but also affects the muscles, joints and internal organs of the upper and lower limbs through the cervical vertebrae and lumbar vertebrae, causing various discomforts. ◆ Once the feet are warm, once the feet are cold, it can reflexively cause the capillary contraction of the upper respiratory mucosa, the cilia swing slowly, and the resistance decreases. The consequence is that viruses and bacteria take advantage of it and multiply in large numbers, which makes people catch a cold. 4, stew tonic health winter diet should not be sticky, cold, because this kind of food is yin, easy to damage the human yang, diet should be based on "tonic." Among the tonic methods, the stew tonic is the best, and the stew tonic takes a long time to make, which is beneficial to the digestion and absorption of nutrients, and medicinal materials can be added appropriately to enhance the curative effect. When stewing, you can choose some high-calorie and high-protein foods according to your personal physique: mutton: It is very suitable to eat mutton in winter, because mutton is warm and can bring heat to the human body. Traditional Chinese medicine says it is a wonderful product for nourishing Yuanyang, nourishing essence and blood, treating lung deficiency and benefiting strain, and it is a good food for nourishing and strengthening. Goose meat: Since ancient times, there has been a proverb that "drink goose soup, eat goose meat, and don't cough all year round". Eating goose soup and goose meat often can prevent cough and nourish the five internal organs. Duck: In winter, besides eating some foods that can strengthen yang, we should also pay attention to nourishing yin. Duck meat is rich in nutrition and is a wonderful nourishing product, especially suitable for people with fever and internal heat, especially those with low fever, physical weakness, less food, constipation and edema. Eating duck is the most beneficial.
