The word “health” was first found in the book “Zhuangzi”. It means to maintain life. Su Wen? The ancient people, who knew the law of yin and yang, the art of harmony, eating and drinking in moderation, living in a regular manner, and not making delusions of labor, were able to be in shape and in spirit, and to end their natural life, and to live a hundred years before leaving. In order to live a hundred years, we must talk about health care, which should start from the embryo – age zero, until the end of life. Different age stages have different health care priorities Pre-conception – infancy: “Class Scripture”: “All men and women who have few desires will be expensive and long-lived, while those who have many desires will be cloudy and die”. Parents are warned that the period before birth is often the decisive period for life and death, so they should pay great attention to abstaining from desire and drinking in order to preserve the essence and blood for the benefit of future generations. When the child is born, the sun and moon are not yet full, the yin and yang are not yet ready, the internal organs and bones are not yet “complete”, the quality of the endowment is not yet determined, if the pregnant woman dresses, eats, lives and acts in a hygienic manner, the diet is moderate, the living is normal, are appropriate to the cold and temperature, not delusional labor, the movement is appropriate, the regulation is appropriate, to ensure physical and mental health, the fetus will be able to “change by things “The fetal growth, development, fetal nourishment and fetal education will have a positive effect on the fetus. After birth, the infant’s health depends on the parents’ nurturing, if the nurturing is appropriate, the infant’s physical and mental development can be healthy. Adolescence: Suwen? The “Sickness machine qi yi protect life set” pointed out: “people want to resist premature aging, the end of the day, should start from a young age, Xun can pay attention to the regimen, can be received to prevent microscopic and eliminate the gradual work”. According to the physiological characteristics of teenagers, it is proposed that “the way to treat them is to regulate their diet, adapt to the cold and heat, and use the medicine of nourishing the nature in order to complete their truth”. Zhang Jingyue advocates that the kidneys should be tonified in children, so as to make up for congenital deficiencies through the action of the latter. Middle age: When people reach middle age, an eventful time, they should pay more attention to nourishing their health so as to prolong middle age and delay the arrival of aging. It is important to preserve the true essence to be healthy in middle age. The adult period is the prosperous stage of life, according to this feature, Liu Wansu believes: “the way of treatment, identify the eight evil, divided labor anonymous, appropriate medicine for the treatment of disease, when reducing its poison, in order to complete its true”. This “reduce the poison” to prevent injury to the right idea, for the fight against premature aging has a very important role. Zhang Jingyue more emphatically: “people in middle age, when a great repair, then re-energize the foundation, still strong half”. Through the middle-aged conditioning and repair, to prepare for entering old age. Old age: When people reach old age, their physiological functions begin to decline. Therefore, Liu Wansu pointed out that “the way of treatment is to follow the spirit and nourish the essence, adjust the internal organs and organs, and perform internal compassion and external protection”, aiming at nourishing the essence, qi and spirit internally and avoiding the evil of the six perversions externally to protect its righteousness and help its weakness. For the elderly, we can take targeted health care measures depending on the deficiency of their yin and yang qi and blood. The physiological functions of the elderly are aging, so they should be cheerful and open-minded, insist on exercise, live a self-care life, be active in their old age, and develop good habits so that all diseases inside and outside will be prevented, and they can enjoy the whole life and enjoy their natural life.
