Chinese medicine has a long history and is the treasure of our traditional culture. It is a science of health care and disease prevention summarized by our working people for a long time, and also contains the theory of treating the unborn, treating the unformed, treating the unspread, treating the untransmitted, and preventing the recurrence of disease after disease. Chinese medicine emphasizes the “unity of nature and man”, that is, man is part of nature, man and nature in harmony, so health care in the focus on food, clothing, housing and transport at the same time, but also pay attention to the changes in the seasons, according to seasonal changes to adjust the health care strategy. First, the spring health principles – rise Yang Qi, strip liver Qi Spring (Spring to Valley Rain) climate change, from winter to spring, people’s ability to fight disease, climate adaptability is weak, epidemic infectious diseases and more, especially for people with weak blood, phlegm and dampness trapped spleen physique, a little inattention will be infected with disease. In addition, liver wood flourishes in spring, irritation and other emotions can easily stimulate liver injury, and the condition of some coronary heart patients is prone to deterioration, while people with hyperactive liver yang are also particularly prone to headaches and dizziness, which is the reason why ancestral medicine has long pointed out that “all diseases are in the head in spring”. In addition, because spring is the time when the bile gas of Shaoyang rises, spring is susceptible to colds, if improper treatment, poor protection, often leading to hepatitis, measles scarlet fever, mumps, epidemic cerebrospinal meningitis and other infectious diseases. Chronic bronchitis, bronchitis, ulcer disease, etc. are also prone to attack in spring. The spring diet is based on the principle of flatness and lightness, with an emphasis on nourishing the liver and replenishing the spleen. Spring is the time when the liver, one of the five organs of the human body, is in season, it is appropriate to eat pungent and warm food, and less cold and sticky things to avoid harming the spleen and stomach, so spring should be appropriate to eat more sweet food, less sour food. In addition, pungent and sweet foods help spring yang, such as onions, ginger, leeks, garlic and other slightly pungent foods are good for the body’s spring yang development. In terms of life and living, it is said in the Book of Internal Medicine that “in spring, people should lie down early and get up early”. People should sleep early and get up early, exercise appropriately to release the “vital” energy, and pay attention to exercise should be warm to adapt to the spring energy. And to make the body and mind feel relaxed and lively, in order to make the body adapt to the spring. In life, we should pay attention to a happy mood, avoid irritation, and remember the idea of “do not kill”, “do not take away”, “do not punish”, so that the liver qi can maintain normal growth and regulation. Throughout the spring, the human body’s meridian gas run in the liver, gallbladder, spleen and stomach, respectively, if the above organs have old diseases, it may recur in the spring, you can health care exercises and health gongfu to strengthen the body, in order to achieve the liver and spleen, dredge the meridians, eliminate the role of stagnation in the body. Second, the principles of summer health – to benefit the qi and nourish the heart, to clear the summer heat and dampness Summer (summer to summer) is the most vigorous season of Yang, hot climate and vigorous vitality. This is the period of metabolism of the human body, the Yang Qi is outside, the Yin is inside, and the Qi and blood are also active on the surface of the body. Summer is hot and rainy, both heat and moisture can cause illness. Summer colds (commonly known as “heat stroke”), heat stroke, and air conditioning diseases are all summer illnesses. Especially for the lung and spleen deficiency, phlegm and dampness trapped in the spleen is the first to bear the brunt. In summer, you should eat more food to clear heat and dampness. Food to clear heat is appropriate to eat in the summer, such as watermelon, bitter melon, fresh peaches, strawberries, tomatoes, green beans, cucumbers, etc.. You can eat a little more food that can benefit Yang and fluid, but the nature should be calm and slightly cool, avoid nourishing and warm products, such as pigeon meat, black beans, wood ear, Wu Wei Zi, Yu Zhu, Cordyceps, etc. In addition, the spleen and stomach in the summer, especially the long summer is most vulnerable to damage, so you should always eat some spleen and stomach products, such as white lentils, yam, lotus seeds, glutinous rice, prunus seeds, white atractylodes, licorice, etc.. In terms of life and living, it is said in the Book of Internal Medicine: “In summer, you should sleep at night and get up early. In summer, it is advisable to go to bed later and get up earlier in order to comply with the changes in the natural world of Yang and Yin. In terms of spiritual conditioning, we should be clear, happy and cheerful, and broad-minded, so that the mind and spirit can be nourished. In addition, summer exercise, it is advisable to choose in the early morning or evening when the weather is cool to carry out suitable projects exercise, such as taijiquan, taiji sword, health care work, radio exercises, jogging, walking, etc.. The amount of exercise should be moderate, do not overwork. Third, the principle of autumn health – moisten the dryness and benefit the lungs, as well as adjust the heart and spleen autumn (autumn to frost) climate from hot to cool, the air moisture reduction, the human body will produce a series of physiological changes caused by dryness, often called “autumn dryness”, such as dry mouth, dry tongue, urine shortage For example, dry mouth, short urine, dry stool, stuffy nose, cough and a series of other symptoms. Many people do not adapt to the stimulation of cold air due to the mucous membrane of the nasal cavity, especially for people with deficiency of qi and yin, and deficiency of lung dryness and fluid, a slight lack of attention will lead to colds and coughs. According to traditional Chinese medicine, dryness is the main gas of autumn, and it is easy to hurt its fluids, so there is the theory of “autumn is moist”, advocating dietary regimen to counteract the “dryness”. Therefore, it is advisable to drink more soups that nourish Yin and moisten dryness in autumn. Pears, sugar cane, grapefruit, loquat, etc. are all good for moistening the lungs. In addition to the main principle of food nourishment to moisten dryness, reduce pungency and increase acidity to nourish liver energy is also its major method. Autumn is gold, taste is pungent, at this time the lung is strong, should not eat too much pungent flavor, to prevent damage to liver qi. However, it should be noted here, do not think that autumn seasonal fruits can moisten dryness and everyone is suitable, but still need to combine the principles of health care with the identification of the body to choose diet. In terms of life and living, it is said in the Book of Internal Medicine: “In autumn, we should sleep early and get up early”. People should go to bed earlier, get up earlier, and do some physical exercise appropriately. For example, jogging in autumn is the most suitable exercise program for young people, jogging can enhance respiratory function and heart muscle function, which is a good fitness method. But it should be noted that if the jogging volume is too small to play a fitness role, if the jogging volume is large, but harmful to the mind and body. In addition, for the elderly Taijiquan, health care work, etc. is not lost as a good method of fitness. Fourth, winter health principles – spleen and kidney, hibernate the essence of winter (winter – cold) is the season of nature everything is closed. Therefore, the principle of winter health care is to strengthen the spleen and kidneys, and to hide the essence, especially for people with Yang deficiency and Liver and Kidney Yin deficiency. Beware of wind-cold colds caused by external evil attacking the latent yang energy in the body. Especially in winter, colds can lower the body’s resistance and aggravate other diseases such as chronic bronchitis, hypertension, heart disease, etc. Therefore, both the general population and people with a high incidence of colds should pay considerable attention to them. After the winter solstice is the time when Yin Qi begins to recede and Yang Qi gradually rises, it is a good time to take tonic, both in terms of food and medicine. When it comes to winter tonic, it can be divided into two categories, one is food tonic and the other is medicine tonic. First on the food tonic, winter food porridge is an economic and health-care significance of the food therapy method. Generally speaking, winter porridge is usually used rice, rice is sweet and flat, while other rice such as millet, millets, barley are sweet and slightly cold, therefore, the winter food rice is more beneficial. Rice has the effect of harmonizing the stomach, nourishing the spleen, strengthening the muscles and bones, and the five organs, in addition to rice porridge, yam porridge is a good nourishment for the kidneys and spleen;. Chestnut porridge has a significant effect on the weakness of the waist and knees or pain caused by the lack of kidney energy; sesame porridge can play a role in the intestines to replenish lung energy, benefit the kidneys, and strengthen the muscles and bones. It is a well-known topic to talk about medicinal tonic, as the saying goes: “Winter tonic, spring tiger”. Every year between the winter solstice and the spring, the use of poultices for tonic has become a form of tonic with traditional Chinese medicine characteristics, which not only can nourish and strengthen the body, but also cure various chronic diseases. In terms of life and living, it is said in the Book of Internal Medicine: “In winter, you should sleep early and get up late. People should go to bed earlier and get up later, so as to adapt to the winter weather, especially pay attention to the time of the morning exercise. Winter is a foggy season, and fog in addition to water vapor, but also contains more dust, pollutants particles, etc., easy to cause respiratory disease. Exercise in foggy weather, it is best to wait for the fog to dissipate before exercise or choose indoor. In addition, winter because of the temperature difference between indoor and outdoor, to exercise outdoors to pay special attention to keep warm and prevent colds. In terms of spiritual conditioning, you should maintain mental and emotional tranquility, avoiding disturbance and delusion, so that the body’s yang energy can be hidden. In the winter, more active and appropriate exercise, such as walking, jogging, doing exercises, boxing; or planting flowers and plants will also make people happy and healthy. According to the four seasons of “spring, summer, autumn and winter”, we advocate to nourish Yang in spring and summer, and Yin in autumn and winter, to live in a normal way, to move and be appropriate, to dress appropriately, and to have a reasonable and balanced diet to adapt to the four seasons of climate, day and night, morning and evening. The four seasons of climate, day and night, morning and evening, regional areas and other changes in the external environment. As the Nei Jing says: “The wise man’s health must be in accordance with the four seasons and appropriate summer and cold, and happiness and anger and living in peace, and yin and yang and adjust the rigid and soft, such as this is the seclusion of evil, long life and long vision.” Those who are good at health should follow the nature, both physical and spiritual, protect the essence, regulate the spleen and kidney, and take appropriate measures to achieve the purpose of fitness and prolong life.
