When the cold winter is healthyWen Wang Wanshun
Health preservation is a hot topic that people talk about at the moment. What is health?As the name suggests, health is the meaning of taking care of the body. To be specific, health preservation is a medical activity that nourishes life, strengthens physical fitness, and prevents diseases through various methods, so as to achieve longevity. The Book of Changes contains a wealth of health preservation theories, which have played a positive role in the formation and development of traditional Chinese medicine health preservation. As the source of traditional health care in our country, it is still influencing us today. 
Yin and Yang balance. 
The balance of yin and yang is the foundation of life vitality and is related to the health of the human body. The Book of Changes talks about the changes of yin and yang, "Yi Yi Tao Yin and Yang", yin has yang, yang has yin, divides each other, and penetrates each other, conveying a huge message to people. Yin and yang here are the root of all changes in the universe and the foundation of Chinese medicine health preservation. Life is the harmonious cycle of yin and yang in the human body, and once this cycle is disrupted, disease will occur. On the basis of China's ancient natural philosophy, the concept of the human body in the Book of Changes puts forward the view of "the unity of heaven and man". Man is a product of nature, according to the "Book of Changes" of the cosmic holographic law, not only the human body is the epitome of the universe, but also the relatively independent parts of the human body are also the epitome of heaven and earth, and there is yin and yang between the Taiji. As far as the human body is concerned, the back is yang, the abdomen is yin, the body surface is yang, and the internal organs are yin. The internal organs are divided into yin and yang, the six intestines and gallbladder, stomach, large intestine, small intestine, bladder, and three jiao are yang, and the five internal organs heart, liver, spleen, lungs, and kidneys are yin. Therefore, the medical process of traditional Chinese medicine is to adjust yin and yang, so that it can obtain a balanced state of yin and yang, and after the introduction of the five elements theory, its theory is more perfect. To study the Book of Changes for health preservation is to grasp the true meaning of the balance of yin and yang.
Hide the yang and the yin.
At present, the solar term has passed the number nine, how to maintain health in the cold winter?The author believes that according to the principle of health preservation that is easy to learn and conform to the time of the day, that is, to conform to the four seasons of yin and yang health, "spring and summer to raise yang, autumn and winter to raise yin". Winter health care should first hide the yang and collect the yin. "Zhou Yi Hexagram Biography" believes that "Kan" is a hexagram in the north, symbolizing winter and the return of all things. "The Yellow Emperor's Neijing, Su Wen, Four Seasons Tune the Spirit" said that the three months of winter, this is called closed, is the season of vitality lurking, all things are hidden, when there is a festival, the water is cold and the ground is frozen, people should go to bed early and get up late.
Make up in the thirty-nine.
Winter should also pay attention to dietary nourishment, after the winter solstice yin will begin to subside, yang will resurge, there is a way is "winter tonic, spring tiger fighting". In winter, people's body consumption is reduced, sleep is enough, appetite is fragrant, easy to absorb and store nutrients, "make up in Sanjiu", at this time tonic can make people's essence stored in the body, and will not get sick in spring. Dietary care should follow the principle of "autumn and winter yin", and it is best to eat high-calorie foods, such as lean meat, soft-shelled turtle, chicken and duck meat, eggs, milk, beans and products. Also eat more fresh vegetables, such as carrots, greens, pumpkin, spinach, sweet potatoes, mung bean sprouts, etc., to supplement vitamins. It is advisable to eat hot food in winter, but not too much of raw and cold, dry and hot things, because it belongs to yin and is easy to hurt the yang energy of the spleen and stomach. At the same time, winter is the time when the kidneys are the main order, to replenish the kidneys and replenish vitality, we must eat more black food, because it enters the kidneys to nourish the kidneys and strengthen the body, such as black beans, black sesame, black rice, etc. In order to keep the yang energy in the body hidden, it is also necessary to maintain mental and emotional tranquility and ensure sufficient sleep time.
Movement to avoid the cold.
The I Ching looks at man as an organic whole. Changes in any organ, cell, or even a certain component are closely related to the whole body. The Book of Changes advocates that we should understand and grasp a healthy physique, and advocate looking at the human body from a holistic perspective. Only when the overall "yin and yang" maintain a state of balance is healthy, otherwise the body is unhealthy, and it is an imbalance of yin and yang. Traditional health practices advocate strengthening physical exercise in winter, as the Yellow Emperor's Neijing says, "action to avoid the cold". In winter, the days are short and the nights are long, the temperature is low, and people's activities are relatively reduced, so the time for physical exercise in winter should be appropriately extended, and the amount of exercise should be appropriately increased (the frail and sick patients are not included). As the saying goes, "winter practice is three-nine", especially in the severe winter, it is necessary to strengthen exercise, so as to play a role in keeping warm and strengthening the body.
