Sleep early and get up late, must wait for daylight, so that the will if the ambush if hidden, if there is a private intention, if you have got, go to the cold on the warm, no leakage of skin, so that the gas is taken away, this winter gas should be, the way to nurture Tibet. Suwen – four qi tune Shen Da Lun said: “In March, this is called closed collection. Water ice and chap, no disturbance to the Yang.” March is the month of winter, starting from the beginning of winter, through the snow, snow, winter solstice, cold, cold, until the day before spring, a total of 90 days and 3 months. This is the season when yang energy is hidden inside, and the natural yang energy is deeply hidden while the yin cold energy is very strong, showing the cold wind, the rivers are frozen and the ground is cracked. During this season, it is important not to disturb the yang energy hidden in the body. How can we do this without disturbing Yang Qi? “Sleep early and get up late, must wait for daylight, so that the will if the ambush if hidden, if there is a private intention, if there has been obtained, to cold on the warm, no leakage of the skin, so that the gas is taken away, this winter gas should be, the way to nurture Tibet.” In order to comply with the tendency of winter Yang Qi dive down, people should properly reduce the activities outside, to go to bed early and get up late, wait until the sun rises, in order to avoid the invasion of cold, to keep the Yang Qi hidden. To make their thoughts and emotions calm and introverted, as if there is a surprise privacy, unexpected harvest, incomparable inner tranquility and pleasure, but without showing their voice. You should also pay attention to avoiding cold and tend to be warm, and not to make your skin open and sweat, so as to prevent the repeated dissipation of yang energy. This is the principle of nourishing and hiding in compliance with the winter qi. In the early summer of a certain year, a female patient of about 30 years old came to the clinic to see a doctor. At that time, people only wore a single coat, but she was wearing a thick warm coat and a jacket, and she was afraid of both wind and cold, and she was sweating more than once. The reason for this is that in the winter, she was suffering from joint pain and muscle tension. She went to a health and beauty center and had a steam session once a day for two weeks, sweating profusely every time. As a result, the joint pain and tightness of the body did not improve significantly, but left behind the symptoms of sweating and fear of wind and cold. This is because the continuous sweating in winter disturbs the internal Yang energy, which is repeatedly leaked out and consumed excessively, resulting in Yang energy deficiency and inability to fix the surface. I used the method of warming the kidney yang and benefiting the qi to fix the surface for three months before gradually improving. Similar patients were encountered more than one later. If this principle of nourishing and hiding is violated in winter, it will damage the kidneys and affect the function of the kidneys to store essence. People advocate winter tonic, mainly for the yin and yang of the kidney. Insufficient kidney yang can manifest as insufficient warming function, with fear of cold extremities, cold pain in the waist and knees, five-shift diarrhea, and long, clear urine. Dizziness and tinnitus, impotence and premature ejaculation, diminished libido, infertility with uterine cold, leucorrhea and puffiness with scanty urine. Warming kidney yang Of course, you should seek medical assistance, while in terms of dietary therapy, warming foods and medicines to help yang, such as antler, antler gum, venison, mutton, beef, donkey meat, shrimp, red ginseng, eucommia, zihejiang, etc., are available. Kidney yin deficiency can be manifested as low nourishing function, dizziness and tinnitus, soreness and weakness of the waist and knees, feverishness of the five hearts, seminal emission and night sweating, coldness of the hands and feet, insomnia and forgetfulness, excessive dreaming, depression, shaking teeth and hair loss, shortness of breath when moving, and swelling of the feet and hocks. In addition to seeking treatment from a doctor, dietary therapy is used to treat the disease with Radix Rehmanniae Praeparata, Cornu Cervi Pantotrichum, Radix Polygoni, Radix et Rhizoma Polygoni, Fructus Lycii, Radix et Rhizoma Ginseng, Turtle Board, and Turtle Meat. In spring and autumn, it is required to follow the law of obedience to the development and internal collection of Yang Qi to maintain health, and in summer and winter, it is required to follow the law of obedience to the exuberance and submergence of Yang Qi to maintain health. But when the summer is extremely hot, but also nap to prevent heat, winter is extremely cold, but also to cold on the temperature, this is the principle of health care to avoid harm. This is called spring and summer nourishing Yang, because it is the Yang movement of Yang Qi. This is called autumn and winter nourishing yin, because it is the yin movement of yang. This is the original meaning of “Nourishing Yang in spring and summer, and nourishing Yin in autumn and winter” in Suwen – Four Qi and the Great Treatise on Regulating the Gods. Later generations and contemporary health practitioners have made a lot of use of this phrase, which can be used as a reference for health care.
