For example, it is pointed out in Yao Qianqian's Prescription of Nourishing Nature and Supplementing House: "The qi of human beings is uncertain. Because of intercourse, it is awkward. " "Three-Yuan Counselor's Life-prolonging Letter Want to Avoid" also said: "Fear of entering the room, yin and yang are weak, sweating and night sweats make people tired." People's emotional activities are closely related to the movement of qi and blood, which in turn affects the physiological functions of the five internal organs. In the state of anger, panic, anxiety and other emotional disorders, it can cause disorder of qi and blood operation and dysfunction of viscera. If the resumption of sexual intercourse consumes Jingxue, it will further damage the body. According to modern research, when people are in a bad mood or nervous, they will inhibit the secretion of sex hormones, hinder the flow of blood to sexual organs, make men's penises unable to erect immediately, and women's sexual desire is low. At the same time, because of the bad mood, the mind can't be highly concentrated, and the sexual response and sexual excitement are not easy to stimulate, which also affects the quality of sexual life.
Second, it is not appropriate to have sex when you are physically and mentally exhausted.
Sexual life can be said to be a process of whole body activity. During sexual intercourse, the qi and blood of internal organs run faster, and their activities increase, which requires a certain amount of physical strength. However, after a long journey, or heavy work, or strenuous exercise, the qi and blood in the body are depleted to varying degrees. At this time, the rest of Jia Yong who forcibly enters the room will inevitably hurt the essence and become morbid. For example, the book "Thousands of women need the side, the house nourishes nature and nourishes vitality" says: "Traveling far into the house is a waste of five labors and few children." "sanyuan counselor's letter to prolong life" said: "forced entry into the room will lead to exhaustion, kidney injury, kidney injury will lead to exhaustion of marrow gas, and low back pain cannot be pitched."
Third, it is not appropriate to have sex after eating and drinking.
"Shoushibao Senators" said: "Overeating, atrioventricular strain, blood overflowing, and infiltration into the large intestine, when it clears blood, abdominal pain, this disease is called intestinal addiction." Eating too much has caused a burden on the spleen and stomach, and sexual intercourse has resumed, so that qi and blood tend to be all over the body, and the qi and blood of the spleen and stomach are correspondingly reduced, which will inevitably affect the normal play of digestion and absorption. Drunk entry is a taboo for sexual health. Wine can confuse people's feelings and damage their internal organs. Entering the room after drinking is easy to exhaust the essence in the kidney, causing endless harm. For example, "Sanyuan Counselor's Life Extension Letter" said: "Drunk into the room, exhausted the liver and intestines. The husband's semen drops less and can't stand the impotence; Women, on the other hand, are going downhill and staying for a long time. Whoever has bad blood will have bad sores. " .
Fourth, be cautious about sexual intercourse during illness.
The patient has deficiency of qi and blood, imbalance of yin and yang, and weakness of viscera. If they have sex during their illness, they may damage healthy qi and aggravate their illness. For example, ternary counselor's book "Avoid" said: "Red eyes should avoid sexual intercourse to avoid cataracts", "Golden sores will heal before they heal, and they will move in the blood, causing sores to rot". Especially in the recovery stage after illness, sexual intercourse should be avoided, otherwise it will lead to the recurrence of the old illness due to house fatigue, and in the worst case, it will worsen the condition and endanger life, which is called "maternal labor recovery" by Chinese medicine. For example, Fang Yao and Lao Fu in Shang Xia pointed out that "the new disease has not lasted more than a hundred days, and the strength has not been calmed down, but those who take atrioventricular, slightly all die".
Fifth, pay attention to the taboo of female sexual intercourse.
Women have special physiological characteristics, that is, menstrual period, pregnancy, childbirth and lactation. Because in these periods, the body often presents a state of insufficient chong and ren, deficiency of qi and blood, and low resistance, and evil spirits often take advantage of it. If you don't abstain from abstinence, it is easy to produce various diseases and seriously affect women's health. Therefore, sexual health suggests abstinence during menstruation and delivery 100 days, while abstinence is required during pregnancy and lactation. Modern medicine believes that women have a wound in the uterine cavity during menstrual period. If they have sex, they will bring bacteria into the vagina, causing menstrual disorders, dysmenorrhea or inflammation of reproductive organs. Having sex in the first three months of pregnancy can cause uterine contraction and abdominal pain, bleeding and even abortion; Having sex in the last 3 months can also easily lead to premature delivery or premature rupture of amniotic membrane. Postpartum women are weak and have poor resistance. If they have sex prematurely, it will cause diseases such as endometritis, uterine bleeding, low back pain and abdominal pain.
