Winter Solstice is the 22nd of the 24 solar terms and the fourth of the six winter solar terms. The winter solstice is the coldest day of the year when yin and yang meet, because the yin pole and yang begin to grow, hence the name. After this, yang energy goes from less to more, and yin energy goes from more to less. We also have to spend the coldest days of winter, which is commonly known as the “three nine days”. After the winter solstice, the “three ninth days”, the weather is cold and the yang energy in the body has just developed and is relatively weak, so it is necessary to protect and nurture carefully, just like a farmer who raises seedlings or a woman who is pregnant. In our daily life, we should avoid the cold, take more rest, exercise properly, and be in a stable mood, so as to protect our newborn yang energy and facilitate its growth and prosperity in the future. Only when the yang energy in the human body is sufficient will it achieve the purpose of eliminating diseases and prolonging life. As the Yellow Emperor’s Classic of Internal Medicine says: “In March, this is called closed, water ice and chap, no disturbance to the Yang, 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 they have got, to cold on the temperature, no drainage of the skin, so that the gas is taken away, this winter gas should be, the way to nourish Tibet. Against it will hurt the kidneys, spring for fistula convulsions, Feng Sheng less.” In daily life, specific guidance is as follows: 1. Do not exercise too much, be quiet. In this way, Yin can flourish and Yang can be born better. For example, a person usually loves sports, then around the winter solstice, it should be appropriate to reduce the amount of exercise, so as to better adapt to the changes in nature, and better for the body. 2, appropriate adjustment of work and rest, try to go to bed early and get up late, less engaged in strong physical or mental labor, so that the body and mind as much as possible in a quiet state, especially not to stay up late. Chinese medicine believes that staying up late is the easiest way to deplete the yin, blood and yang. 3, the winter solstice in the body of Yang vigorous growth, at this time the most easily absorbed tonic to hide the external nutrition, and play its tonic effect, so as to achieve the purpose of health with half the effort, so there is a “winter tonic” said. Chinese medicine wormwood, ginseng, sliced is the three major tonic; food therapy to eat some lamb, dog, pigeon meat and black food such as black rice, black beans, black sesame, black dates, black fungus, black mushrooms, black bone chicken, etc. is a good choice; winter and is the season of the fruit to the warehouse, many nuts such as walnuts, chestnuts, peanuts, pine nuts, hazelnuts, lotus seeds, etc., with kidney, brain, skin, hair and other effects, winter consumption, the benefits of a lot of . 4, the human back below the diaphragm is the yin of Yang, above the diaphragm is the yang of Yang, and to Yang point is from the yin of Yang to Yang of Yang, that is, the place where yin and Yang meet. Therefore, around the winter solstice, massage the Zhiyang acupuncture point located on the back has the effect of replenishing yang energy.
