A. The origin of the winter solstice As we all know, the winter solstice, the northern hemisphere sunshine time is the shortest, the sun in this day directly on the Tropic of Capricorn. Therefore, the winter solstice is regarded as the beginning of winter in astronomy, and the winter solstice, cold, cold, spring, rain and stirring six festivals are counted as winter. From the day after the winter solstice, the sun will gradually shift from south to north, and the daylight in the northern hemisphere will gradually lengthen. In general, this day is the time when the yin of nature is in full bloom and decay, and a yang is beginning to emerge, which is “the arrival of yin and the beginning of yang”. The winter solstice in Chinese medicine “Suwen – the four qi tuning Shen Da Lun” day: “summer in March, this is called the Fuxiu. The air of heaven and earth intersects, and all things flourish. Night sleep and get up early, not tired of the day, so that the will is not angry, so that Huaying into the show, so that the gas can be released, if the love of the outside, this is the summer gas should be, the way to nurture the long; contrary to the sad, autumn for bruises and malaria, the harvest less, the winter solstice heavy illness.” Therefore, in order to respond to the summer in March, the gas of the summer show, people should also sleep at night and get up early, no aversion to the day, no anger, gas to drain, love outside, so as not to affect the way of nourishing its growth. Otherwise, can not comply with the growth of summer gas is sad, autumn will develop for the cold and heat to and from the disease, for the autumn gas convergence of the essence will be less, to the winter solstice will develop for the internal deficiency of serious illness. From the perspective of the five elements, the heart is fire in the five elements, through the summer, if the summer is lost in the way of health, the heart fire injury, winter is water, water grams fire, so the winter solstice heart fire further damage, the development of serious illness. Suwen – four qi tune Shen Da Lun: “the sage spring and summer to nourish Yang, autumn and winter to nourish Yin, from its roots, so with all things sink and float in the door of growth.” This is the basic principle of regulating yin and yang in the four seasons. The “spring and summer” in the Nei Jing refers to the period from the winter solstice to the summer solstice. As the saying goes, “If you make up for the winter in the third nine days, you will be free of disease and pain in the coming year. The ancients followed the natural practice and chose to take tonic at the winter solstice, when the yang energy rises, so it makes sense to take care of the yang energy and take care of it. This is the theory of “Heaven and Man correspond to each other” in Chinese medicine, which believes that the functional activities of the human body are consistent with the changing laws of heaven and earth, yin and yang, and the four seasons, and are influenced and regulated by the laws of nature, which is the basis of Chinese medicine and time medicine. Third, hypertension is also affected by the environment Modern research has also found that the onset of cardiovascular disease and natural environmental changes are closely related to the data show that the onset of coronary heart disease and the average daily temperature is negatively correlated, and the average daily air pressure is positively correlated. Strong winds and cooling weather also tend to cause a significant increase in the incidence of hypertension and secondary strokes. Further, studies have shown that chronic exposure to high levels of suspended particles may lead to elevated blood pressure. This study suggests that environmental pollution may be an environmental factor in the development of hypertension, and that the mechanism may be related to its contribution to the progression of atherosclerosis. After the winter solstice, the average air pressure gradually drops and the average temperature gradually rises in all regions of China. If the body cannot adapt itself to the changes in the external environment and Yang cannot return, diseases will arise, and the heart with Yang will be the first to suffer. So cardiovascular patients should have the right way to maintain their health. 1, the cold body can be tonic winter solstice dumplings is to take the meaning of tonic. According to legend, at the end of the Eastern Han Dynasty, there were serious disasters around the country, folks were yellow and thin, starving and cold, many people’s ears were frozen. The “Sage of Medicine” Zhang Zhongjing then asked his disciples in Nanyang Dongguan set up a medical hut, set up a cauldron, in the winter solstice day she “delicate ears” to cure frostbite. He boiled mutton and some cold-repelling herbs in a pot, and then fished out the mutton and the medicine and chopped them up, and wrapped them into ear-like “delicate ears”. The people ate the “delicate ears” and drank the “cold-elimination soup”, which warmed their bodies, warmed their ears, and cured their frostbitten ears. Therefore, according to their own physique, choose the appropriate tonic method. 2, blood pressure fluctuations can be foot bath Boil the medicine into water for foot bath, the drug through the capillary circulation into the body, to regulate endocrine, nourishing Yin and kidney, calming liver fire and other effects, but also to improve blood circulation, to lower blood pressure. Especially suitable for taking antihypertensive drugs in winter is not effective, or pre-blood pressure fluctuations, poor control of hypertension patients. 3, to keep warm, rubbing hands, often sunshine back Winter is the season of various heart diseases, pay attention to the whole body and heart parts of the warmth, to reduce the occurrence of such diseases have a direct relationship. There are many important acupuncture points on the human hand, such as Laogong, Yuzhishan and Hegu. By rubbing the palm of the hand and rubbing the fingers can fully stimulate the Laogong point located in the heart of the hand, allowing the heart to gradually get excited. The back is the yang of the body, wind and cold evil can easily invade the body through the back and cause external cardiovascular and cerebrovascular diseases. The climate is cold at the winter solstice, when the sun is full, often sun back helps to benefit the body yang. 4, appropriate and reasonable exercise movement is Yang rise, exercise is an important way to resist the cold, the body moves, the cold will immediately away from the body. But for people with cardiovascular disease, the form and intensity of this exercise must be carried out under the guidance of a doctor. Certainly not to exercise in the foggy weather.
