Kidney is the foundation of nature and the source of life. It has the functions of storing sperm, controlling water and controlling pulp. Therefore, if the kidney is full of qi, it will be full of energy, strong bones and muscles, brisk walking and quick thinking. When kidney deficiency occurs, the yang is weak, the waist and knees are weak, and it is easy to get cold and get sick. Normal renal function in winter can adjust the body to adapt to the changes in severe winter, otherwise it will cause metabolic disorder and cause diseases. Therefore, it is very important to pay attention to the maintenance of kidneys in winter. Kidney deficiency is divided into yin deficiency and yang deficiency, which is called kidney yin and plays a nourishing and moistening role in various organs of human body. It is called kidney yang, which warms and promotes the activities of various organs. According to the difference between kidney yin and kidney yang deficiency, the kidney should be supplemented by corresponding methods. People with deficiency of kidney yin often have symptoms such as lung heat, dry throat, soreness of waist and knees, dizziness, tinnitus and reddish tongue coating, which can be nourished by sea cucumber, medlar, turtle and tremella. People with kidney-yang deficiency often have symptoms such as chills in limbs, listlessness, backache and tinnitus, pale tongue and fat body. Mutton, velvet antler, Psoralea corylifolia, Cistanche deserticola, Cinnamomum cassia, Alpinia oxyphylla and so on should be selected. Traditional Chinese medicine believes that the functional activities of limbs, including joints, bones and muscles, are dominated by liver and kidney. Therefore, there is a saying that "the kidney dominates the bone, and the bone is the kidney". People who are good at keeping in good health should insist on physical exercise in winter, so as to achieve the effects of nourishing tendons and strengthening the kidney, relaxing tendons and activating collaterals, dredging qi pulse and enhancing their own resistance, thus achieving the purpose of tonifying kidney and strengthening the body. Walking, jogging, playing ball, doing exercises, boxing and sword dancing are all suitable for winter exercise. Pay attention to keep warm during winter exercise, especially for the elderly and infirm. Be sure to put on clothes in time when you sweat, and if possible, you will put on sweaty underwear to prevent colds. Sticking to massage can eliminate fatigue and protect the kidneys. Massage can be done by the following methods: ① rubbing the waist and rubbing the eyes: after rubbing hot, press your hands tightly against the waist and rub hard for 30 times. "The waist is the house of the kidney" Rubbing the waist and rubbing the eyes can dredge the tendons and enhance the function of the kidney. ② Kneading Dantian: Rub your hands with heat and massage at abdomen Dantian for 30-50 times. Dantian is the place where human qi and essence condense, and it is the foundation of human life. Commonly used this method can enhance human immune function and improve human resistance, so as to achieve the purpose of tonifying kidney and strengthening body, which is conducive to prolonging life. Because people's yang is rooted in the kidney, cold pathogens are the most likely to damage kidney yang. It can be seen that in the severe winter, if you want to keep out the cold, you must first raise your kidney. Life in winter should be regular, and sports activities should be carried out as much as possible, which can not only enhance the kidney-qi function related to human immunity, improve disease resistance, but also help lung-qi to breathe, and prevent various chronic respiratory diseases because of "kidney governing qi". "Kidney governs bone", knocking teeth frequently in winter, benefiting kidney and strengthening kidney. Kidney is "saliva in liquid". In winter, the tongue reaches the upper jaw, and when the saliva is full, it can be swallowed slowly, which can nourish the kidney essence. The meridians of the kidney start from the foot, and Yongquan point in the heart of the foot is its main point. It is best to soak your feet with hot water before going to bed at night in winter and press the center of your feet. In winter, people are in a state of "Yin flourishes while Yang declines", so they should bask in the sun to help Yang Qi in the kidney rise. Kidney and bladder, one dirty and one fu-organ, are the exterior and the interior of each other, and the bladder meridian runs on the back, and cold evil invades. In winter, attention should be paid to keeping the back warm and wearing cotton or wool vest to protect kidney yang. The ancients believed that "the kidney is the master of stinging and the root of hiding". Therefore, excessive sexual intercourse is forbidden in winter, and excessive sweating is forbidden during work and exercise to prevent kidney yin and yang from disharmony. Diet adjustment is also very important for tonifying kidney and preventing colds. In winter, mutton, dog meat, sparrow meat and other foods should be selected. These foods warm the kidney and strengthen yang, and have high calories, which are especially beneficial to those who are physically weak and afraid of the cold. You can also eat some foods that can tonify the kidney, such as walnuts, chestnuts and longan. "Black food" can enter the kidney and strengthen the kidney, and the choice of food should be appropriate, such as black rice, black beans, black sesame seeds, black dates, black fungus, black-bone chicken, kelp, seaweed and so on. Always eat all kinds of warm porridge in winter. If you cook these foods into porridge, you can not only drive away the cold, but also treat diseases with diet. Zhang Jingyue, a famous doctor in Ming Dynasty, famously said, "Those who are good at nourishing Yang will seek Yang in the shade; those who are good at nourishing Yin will seek Yin in the yang. "For the elderly whose kidney yin essence is gradually declining, they can eat soft-shelled turtle, soft-shelled turtle, medlar and other yin-protecting products in winter. Drinking in winter should not be too salty, because the salty taste enters the kidney, which makes the kidney water cooler and disturbs the heart yang. In addition, avoid cold food, so as not to "add insult to injury" and hurt Yuanyang.
