According to traditional Chinese medicine, winter is the season when Yin energy is strong and everything is collected. In terms of the human body, metabolism is also at a relatively slow level. To maintain health in winter, we should avoid cold and protect yin, so that yin and yang are relatively balanced and healthy. Modern medicine believes that the low temperature environment in winter can easily induce attacks of coronary heart disease, hypertension, chronic obstructive pulmonary disease, asthma, arthritis and other diseases. Chronic bronchitis, asthma patients will gradually aggravate their condition in winter, and the stimulation of cold air will trigger acute attacks. Winter health, disease prevention should pay attention to the following aspects: 1, the spirit of the importance of the “hide” winter nature sting insects hide, nourish the essence of storage, in order to be ready for the coming spring. Human metabolism at this time is also in a relatively slow period. Therefore, winter health should focus on “hide”, that is, in winter to keep the spirit quiet, to find ways to control their own mental activities, to hide the gods inside, not exposed to the outside. Specific practices: one is to regulate the bad emotions, keep the mind calm; second is to extend the time of light. Because the winter light time is short, is also a cause of emotional depression. When darkness comes, the human brain pineal gland melatonin secretion enhanced, it can affect the human mood, and light can inhibit the secretion of this hormone. 2, life is important to prevent “cold” After entering the winter, “sleep early and get up late to wait for daylight” is the basic requirement for health, sleep early to nourish the body’s yang energy. It is best to get up after the sun comes out, when the body’s Yang Qi rises rapidly, the content of adrenocorticotropic hormone in the blood is also gradually rising, at this time to get up, clear-headed, sharp wit. And the high concentration of negative ions in the air in the morning is also very beneficial to the human body. Commuters may be very difficult to get up early, which should try to go to bed early and not stay up late. Winter avoid tightly closed doors and windows, because people from the respiratory tract, skin discharge of harmful substances, plus the closed space of toxic gases diffuse in the room, will infringe on our body, so the windows should be properly opened for ventilation. Winter room temperature should be kept constant control between 18 ℃ ~ 22 ℃ is better, because the room temperature is too low is easy to hurt the human body Yang, too high is the indoor and outdoor temperature difference, it is easy to go out to external activities. 3, the diet should be warm winter cold, the human physiological activities need more heat to maintain. According to Chinese medicine, winter is the time when the body’s yang energy is hidden, that is, the human physiological activities due to the influence of winter climate characteristics and convergence, slow down. Winter tonic is a traditional method used in China for thousands of years to prevent diseases and strengthen the body. Winter tonic can make the nutrients transformed into energy to maximize the storage in the body and nourish the five organs. Because Chinese medicine believes that winter corresponds to the “kidney” of the human body, and the five flavors of salt into the kidney, salty taste has the effect of nourishing Yin and blood, softening and dispersing the knots. In addition, winter should eat more warm and protective Yang products to resist the cold, such as eating more mutton, dog meat, beef, etc., can also eat more cinnamon, walnut meat, walnuts, chestnuts, dates, yams, fungus, etc.. Of course, vegetables are also indispensable, such as soybeans, carrots, rape, mustard, leeks, etc. Winter should eat less cold food, such as crabs, sea shrimp, watermelon, grapes, etc. Of course, food therapy should be different according to each person’s physique. Such as spleen deficiency, qi deficiency, manifested as weakness, shortness of breath, anorexia, abdominal distension, thin stools, fear of cold, can be used to strengthen the spleen and benefit the qi food, such as glutinous rice, dates, lentils, yams, carrots, chestnuts, etc.. Some people have cold extremities and fear of cold after winter, and put on sweaters and autumn pants early. Chinese medicine believes that this is mostly due to Yang deficiency body, Yang Qi does not reach the four ends (limbs). Diet can choose mutton, chicken, dog meat, walnut meat, jujube, cinnamon, etc. In short, after the winter diet to warm tonic, to resist the arrival of the cold winter. 4, exercise is indispensable Winter exercise is essential because outdoor activities in winter can increase heat production, regulate metabolic functions, enhance cerebral cortex excitation and thermoregulation. However, due to the cold weather in winter, the limbs are more rigid, so it is very important to warm-up activities before exercise. Such as stretching limbs, jogging, a small amount of light equipment exercises, so that the body slightly sweating, and then carry out high-intensity fitness exercise. Exercise clothing according to the weather conditions, always to keep warm to prevent colds, especially after exercise to put on clothes in time to avoid catching cold. Exercise should also be different according to each person’s physique and age. For example, people with cardiovascular and cerebrovascular diseases should be prohibited from doing strenuous exercise, such as playing ball, mountain climbing, etc. The elderly with respiratory system disorders, such as slow branch, emphysema, pulmonary heart disease, etc., should avoid the stimulation of cold, exercise should be selected in the morning, noon sunshine sufficient time, so as not to induce the onset of disease. The elderly should pay more attention to keeping warm, and should also avoid getting up too early to exercise, to prevent insufficient blood supply to the brain to induce the formation of a stroke. Overall, the winter exercise to adhere to, warmth is the key, the content of the exercise to vary from person to person.
