Health preservation is to maintain life. Under the guidance of the theory of traditional Chinese medicine, it follows the changing law of the biochemical set of Yin-Yang and Five Elements, scientifically regulates the human body, and maintains the health and vitality of life. There are many contents in TCM health care. For example, mental health care refers to maintaining the body, reducing diseases, improving health and prolonging life by relaxing the mind, adjusting emotions and adjusting life. China's traditional health care emphasizes the relationship between man and nature, and thinks that man should adapt to the changes of natural environment and climate in four seasons, actively adjust himself, keep a balance with nature and avoid the invasion of external evils. In the Book of Changes, "Yin and Yang are the Tao" and "the image of law is not only heaven and earth, but also flexible in four seasons". "Tao is natural" in Tao Te Ching is the basic requirement of TCM health preservation. TCM health preservation is a treasure of China traditional culture, and its purpose is to cultivate vitality, prevent diseases and strive for health and longevity. Traditional Chinese medicine health care includes food, medicine, acupuncture, qigong and other health care technologies. The ancients thought that the method of health preservation was nothing more than supplementing nature, and the method of supplementing nature was nothing more than supplementing essence, transforming qi, gathering qi, balancing yin and yang, and coordinating qi and blood of viscera, thus ensuring the health and strength of the body. Therefore, the maintenance of vigor is the most important health care content and the foundation of human health care. In traditional Chinese medicine, the most important physiological and functional activities of the human body are summarized as essence, qi and spirit, which are considered as the basis of life and the three major elements to maintain the overall life activities of the human body. As early as 2000-3000 years ago, Zhouyi, Huangdi Neijing and Daodejing had a complete set of health preservation principles, which were like a treasure house, and were worthy of further study and reference by future generations. Traditional Chinese medicine believes that heaven and earth are the big universe, while human body is the small universe, and heaven and man are interlinked. People are not influenced by heaven and earth all the time, and all changes in heaven and earth will affect people. Therefore, TCM health care emphasizes the unity of man and nature, and the methods of health care are cold, hot and cold with the climate change of the four seasons, which should be adjusted appropriately. For example, after the summer solar term, high temperature and rainy weather alternate, and the climate is hot and humid. People in the city drink ice water in air-conditioned rooms, which often leads to the interweaving of cold and heat, forming damp evil. Dampness is yin evil, which hinders qi activity and leads to yang deficiency. Therefore, attention should be paid to nourishing yang in summer health care, which is the practical application of "nourishing yang in spring and summer" in Huangdi Neijing. Traditional Chinese medicine health care pays attention to both physical and mental aspects, not only physical exercise and maintenance, but also spiritual cultivation and recuperation. The body will affect the mind, and the mind will also affect the body. They are two sides of an organic whole, and they are indispensable. A person with a balance of yin and yang is the healthiest person, and the goal of health preservation is to achieve a balance of yin and yang in body and mind. What is Yin? Yin is the material basis of the body. What is Yang? Yang is energy and external activity. Yin and Yang are relative, and everything that heats up upward belongs to Yang; Anyone suffering from cold belongs to yin. The reason why the body is alive is because of the imbalance of yin and yang, which leads to yang excess or yin excess, yin deficiency or yang deficiency. As long as we try to reduce too many parties and increase too few parties, and restore the original balance of yin and yang here, the disease will naturally disappear. Therefore, TCM health care highly emphasizes the balance of yin and yang and healthy life. Disclaimer: The above content comes from the Internet, and the copyright belongs to the original author.
