Traditional Chinese medicine believes that excessive lust hurts people's essence, qi and spirit. Essence, qi and spirit are the three treasures of human beings. Because essence can make people angry and qi can make people energetic, so if you want to keep in good health, you must first raise essence. When you are full of essence, you will be full of essence, you will be healthy, and when you are healthy, you will be less sick. Inside, the five internal organs are full of flowers, and outside, the skin is moist, the face is radiant, the eyes and ears are smart, and the old age is strong. Therefore, health care experts regard spirit as three treasures, especially essence as treasure. To value essence, we must first abstain from lust and desire for harm. In this regard, predecessors have a lot of discussion and practical experience, which are also briefly introduced as follows: (1) Sexual life is the normal nature of human beings. Normal sexual life makes male huan obedient, harmonious between Yin and Yang, and beneficial to physical and mental health. "Eight Notes on Respect for Life" said: "The Yellow Emperor said that Yin and Yang are Tao, Yin and Yang are disease, and Yin and Yang are not harmonious. If there is no autumn in spring and no summer in winter, then harmony is a sacred adjustment. People can't reach an agreement, but they are content to keep secrets and be innocent. In other words, sexual life between men and women is a normal physiological phenomenon. Being single (that is, being partial to Bai Yang) can make people feel bad and even cause various diseases. The way of life is not that men and women don't have copulation, but that they don't overdo it and don't vent their essence in vain, so as to protect their innocence. (2) Sexual life should not be premature. Confucius, a great thinker and educator in ancient China, once said: "When you are a teenager, your blood gas is uncertain, so you should quit it." According to Gu Tianzhen's theory, the physiological process of human growth and development and the important role of kidney are discussed. Men began to be filled with kidney qi at the age of eight, and at the age of sixteen. Based on kidney essence, it can promote the production of Tiangui and promote reproductive function, and the essence can be leaked out. If you have sex, you can have children. But at this time, relying on qi and blood, premature sexual intercourse, and even excessive sexual life will damage the essence. Like flowers in the garden, they grow long ago and wither first. Therefore, it is pointed out in the Four Essentials of Health Care in Wan Family Biography: "Today, men have few prescriptions, but before 28, they followed women, with sparse essence, diarrhea when the essence is not full, and the five internal organs are dissatisfied, and they will be ill in the future." It is also pointed out that "deficiency of kidney essence will be given to viscera, and deficiency of viscera essence will be given to bone marrow, so urine will be urinated when viscera essence is exhausted." ..... how long will it last? "It shows that premature sexual intercourse affects the growth and development of other organs and even causes various diseases. A famous monograph on gynecology in Song Dynasty said: "Although a man is sixteen and refined, he marries at thirty; Although a woman reaches the age of 14, she will get married at the age of 20, "and" yin and yang are perfect, and then she will be pregnant, pregnant and have children, and her son will be strong and live long. "From the perspective of prenatal and postnatal care, it is proposed that sexual intercourse should not be premature, the age of late marriage and the benefits of late marriage. This is consistent with the spirit of the marriage age stipulated in China's marriage law that men should not be earlier than 22 years old and women should not be earlier than 20 years old. (3) Sexual life should not be overindulged. Many health documents in China emphasize that sexual life should not be overindulged. For example, the letter of life extension from Sanyuan Counselor said: "Too much worry impairs the essence. People can cherish their lives, but they are in good health. Anything that can be heavy is fine. Liver essence is not solid, dizzy and dull; Insufficient lung essence and emaciation of muscles; Kidney essence is not solid, and essence and qi decrease; Spleen essence is not firm, teeth are floating and painful. If dissipation is really progressive, illness will follow and death will follow. "It is pointed out that excessive indulgence is harmful to the body and internal organs. The book also pointed out: "The way of Yin and Yang, the semen is empty, so I would rather it, and the day after tomorrow is not old." It is considered that nourishing sperm is one of the important measures to prolong life. (4) Sexual life should be taboo. The ancients believed that drunkenness, over-treatment, anger, fear, unhealed, and new illness will damage the body and even cause various diseases, so it should be taboo. For example, "Three-Yuan Counselor's Life-prolonging Book" said: "Drunk entering the room, fatigue will damage the liver, husband's essence will fail, impotence will not be able to afford, female's life will decline, and long-term retention of bad blood will lead to bad sores", "overeating the room, exhausting blood gas, overflowing into the large intestine, bloody stool, abdominal pain, and illness name withdrawal", "In anger, try your best to have sex and exhaust the essence. When you enter a room in fear and yin and yang are weak, you will experience syncope, spontaneous sweating, night sweats, and accumulated fatigue. " "Swimming into the room is exhausting." "The golden sore will be bad before it is bad, and the blood gas will be corrupted." "Those who endure urine entering the room will suffer from disease, stem pain, facial color loss, or sudden pain under the umbilicus and die. "Treatise on Febrile Diseases also pointed out:" A serious illness is new and bad, blood gas is not recovered, residual heat is not exhausted, and yin and yang are vigorous, so patients call yin and yang easy. "Some of the above records still have practical significance, such as getting drunk and entering the room after fear is often the cause of impotence. In a word, sex life is taboo, which can prevent all kinds of sexual dysfunction.
