The ancients said, "Food, color and sex are also important." Sex, like eating, is a human instinct and a physiological and psychological need. Therefore, as long as they are normal people, everyone has sexual desire. But some people misunderstand that sexual life hinders longevity. So some elderly people have normal sexual function, but they stop having sex. This kind of abstinence is harmful to both husband and wife. Can human abstinence prolong life? Traditional Chinese medicine has always believed that abstinence is not conducive to physical and mental health. The ancient health-preserving book "The Book of Sanyuan Yanshou Counselor" said: "The Yellow Emperor said: Yin and Yang are the Tao, and Yin and Yang are diseases. He also said: I don't know these two. If there is no autumn in spring and no summer in winter, it is called holiness. Saints are always harmonious, but being naive is more expensive than keeping secrets. " This means that the unity of opposites between Yin and Yang is a universal law of nature. Under normal circumstances, yin and yang are in balance, and the human body must maintain balance to ensure health. When yin and yang rise and fall, they will get sick. Moderate sex life is a means to reconcile yin and yang. Human kidney essence is constantly produced due to the nutrition of Houtianshui Valley. Sufficient kidney essence will help the heart fire, which will "burn in the fire" and produce sexual requirements. Therefore, sexual intercourse is neither essential nor frequent. If appropriate, it is good for health. Middle-aged women are not abstinent. Chinese medicine also believes that long-term abstinence will lead to "blood stasis and malnutrition" and make it "weak and useless". It shows that the result of long-term abstinence will make it lose its sexual function forever. Because abstinence destroys the balance of yin and yang and suppresses people's sexual instinct, the sexual desire gathered by the human body can not be released, but it will bring harm to people's spirit and body. Alice, an American sexologist, said: "The result of abstinence will cause a small-scale commotion and make people feel uncomfortable." Modern sexology and medical experts masters and Johnson's research also confirmed this point. Because the sexual tension that drives sexual desire is a kind of biological energy, it obeys the law of conservation of energy and can only be transformed, not disappeared. Normal and moderate sexual life can realize sexual desire and release sexual tension. When sexual desire is not vented for a long time, "impotence" will occur, mostly in men over 50 years old. Most of them are caused by the death of their wives and long-term asexual activities. Long-term abstinence affects sperm quality. Abstinence is not conducive to health and longevity. It has been reported abroad that the aging and mortality of abstinence people are higher than those who have normal sex lives by more than 30%. Russian and Japanese survey data show that most of the spouses of some longevity people are still alive. And the widowed have a shorter life. Therefore, health and longevity do not belong to those who give up drinking.
