The physiology of the elderly is characterized by “impotence and exhaustion of the internal organs”, and the functions of the internal organs are declining. In case of improper diet, uncomfortable living, wind and cold, emotional stimulation and other factors, it may cause sudden changes in the functions of the internal organs, and thus various diseases will come one after another. Therefore, the most ideal way for the elderly to maintain a long life is to prevent and reduce the occurrence of diseases in old age. Adapt to nature, follow the sky to avoid evil The movement of the yin and yang of nature affects the strength and weakness of the yin and yang of the human body, and the human body must conform to the changes of the yin and yang of nature to maintain normal life activities, the so-called “unity of heaven and man”. If you cannot adapt to the changes in nature, you will suffer from diseases and even endanger your life. As “Suwen – four qi tune Shen Da Lun” said: “The four times of yin and Yang, the root of everything, …… against its root is to cut its capital, bad its true carry on. Therefore, the yin and Yang four times, all things are always the same, death and life of the essence. Against it is disaster, from it is harsh illnesses can not afford”. The natural environment is closely related to the health and longevity of the elderly, and there are both favorable and unfavorable aspects. The favorable natural gas should be conformed to, and the natural unhealthy gas should be avoided in time, that is, “appropriate cold temperature, careful living”. The “Su Wen – Shang Gu Tian Zhen Lun” says: “Tranquility and emptiness, the true energy from the, the spirit within the guard, the disease from?” That is to say, the mind should be kept quiet and pure, no distracting thoughts, the body’s true qi can be harmonious, the spirit within the guard and not dissipate, disease will not occur. Chinese medicine has the “seven emotions”, that is, happiness, anger, sadness, pity, fear and fear. Generally speaking, the seven emotions are different reflections of the human body to external things, which belong to the category of normal mental activities and cannot cause disease. Only sudden, strong or long-term persistent mental stimulation can affect the physiological functions of the human body, so that the internal organs function disorders, leading to the occurrence of disease. In particular, to maintain an optimistic spirit, try to avoid excessive worry, sadness and panic, as the saying goes: “smile, a decade less”, but also pay attention to the “degree” of the problem, too much is too little. Different physiques and personality types, there are individual differences in the activities of the internal organs, Qi, blood and yin and Yang, their emotional and mental activities also have different characteristics, adjust the emotional and mental according to personality characteristics, using different measures. Older people are impotent, the spirit of depletion, “the sex is uncertain, stop like a child”. In the family relationship, the younger generation should fully understand them, try to put in their favor, avoid their aversion, so that their spirit is happy and relaxed. Eat in moderation, quit the bias Suwen – Shanggu Tianzhen said: “calm and void, the real gas from the, the spirit within the guard, the disease is safe from?” That is to say, the mind should be kept quiet and pure, no distracting thoughts, the body’s true qi can be harmonious, the spirit of internal defense and not dissipation, disease will not occur.

In the family relationship, the younger generation should fully understand them, try to cast their preferences, avoid their aversion, so that their spirits are happy and relaxed. The elderly must be regular in their living and rest. “The “irregularity of living” will often be “half a hundred and decline. According to the change of day and night seasons, make the corresponding work and rest, which is beneficial to the health of the elderly. Appropriate labor and physical exercise can help the circulation of blood and qi and increase physical strength. Fan Ye’s “Book of the Later Han Dynasty” contains Hua Tuo’s claim: “The human body wants to work, but not to make the extreme ear, shaking, then the grain gas can be eliminated, blood circulation, disease shall not be born, like a household pivot, the end will not perish. The “Five Animal Play” created by Hua Tuo is very useful for disease prevention, so it can be seen that the elderly often participate in some labor within their reach and practice some appropriate gongfu is very beneficial to their bodies. At the same time, the elderly must combine work and rest, and work and rest in moderation. Before the disease, medicine bait to prevent the old “Su Wen – four qi tune Shen Da Lun” said: “not to treat the disease to treat the disease, not to treat the chaos to treat the chaos, …… the disease has become and after the medicine, chaos has become and after the treatment, such as thirst and digging wells, buckets and cast cones, not also late “. This “rainy day”, “prevention is more important than cure” spirit, very relevant. The elderly are physically weak, the internal organs are impotent, appropriate to take some tonic drugs, indeed, can play a certain degree of anti-aging and strengthen the role of the body. In the specific application, it is necessary to identify the specific deficiencies of the five organs, yin and Yang, Qi and blood and targeted tonic. To identify the deficiency of the tonic, targeted, in order to make up the effective, but not, to avoid the “deficiency of the tonic”, “over-supplementation on fire” and other unfavorable phenomena. Although there are countless tonic and health care products in the society, and many elderly people do take many kinds of tonic drugs at the same time, we still advocate that we should not be overly superstitious and rely on drugs, and try not to use medicine if we can use food tonic. At the same time, it is also very important to cultivate the body and nourish the mind. Sun Simiao pointed out: “Although you always take medicine and bait, but do not know the art of nourishing the mind, it is also difficult to live a long life. Therefore, “the law in the yin and Yang, and in the arts and figures, eating and drinking in moderation, living in a normal way, not delusion for old age”, in order to “to spend a hundred years before going”.
