In fact, spring is also a good time for couples to make love and even give birth to new life, so the author goes with the flow: the plan of "sex" also lies in spring.
In the Chinese medical theory, "the correspondence between man and nature" runs through the whole system, and sexual intercourse is no exception. Neijing holds that the main qi of the four seasons is "spring, long summer, autumn harvest and winter storage". Everything is like grain growth, which grows in spring, matures in summer, harvests in autumn and stores in winter. Sexual intercourse should also be carried out in this way. Although ancient physicians unanimously advocated abstinence in sexual intercourse, they could not indulge frequently; But in spring, sex can be "casual".
According to the meridian theory, human genitals are surrounded by the liver meridian. In spring, the liver meridian governs qi, which is soothing and most afraid of depression. Therefore, maintaining an appropriate frequency of sexual life in spring is also very beneficial to improving mood!
Coincidentally, modern medicine also thinks that spring is the season of good birth and excellent child rearing. The sperm quality of men is better in winter and spring, and the pregnancy rate of women is the highest in spring. An Israeli expert conducted a four-year follow-up survey on 650 women who received artificial insemination. The results show that the change of four seasons has obvious influence on women's pregnancy and delivery. Spring is the best pregnancy season with the highest success rate, followed by summer and winter, and autumn is the lowest. The reason is that the sunshine time is longer in spring, and more sunshine is helpful for pregnancy.
And pregnant in spring, the second trimester is just summer or autumn, when there are fewer flu and viruses, the chances of pregnant women being infected are reduced. The development of fetal brain is just after the second trimester, especially in the last trimester. At this time, there is less infection during pregnancy, which is undoubtedly beneficial to the normal development of fetal brain.
In addition, pregnant in spring, born in autumn, autumn is the harvest season, there are more fruits, and the nutrition of postpartum mothers is easy to be guaranteed.
Therefore, to learn the way of keeping in good health, we must know what is appropriate and what should be taboo in sexual life.
First, the principle of sexual health:
Li Pengfei, a medical scientist in the Yuan Dynasty, said: "If you want Fukashi, you must not be early, you must not be vertical, and you must not be strong." It can be used as a standard of atrioventricular health. Endless desire illustrates the necessity of sexual intercourse; Discussed the disadvantages of early marriage. Desire can't refer to opposing indulgence; If you want to be strong, you can't force your way into the room, so as not to consume essence and hurt your kidneys. This standard still has practical value today.
Second, the necessary environment for sexual intercourse:
The ancients had three taboos: "avoid cold and heat, avoid wind and rain, this day is taboo;" Drunk, angry, sad and scared, this person is also taboo; Mountains and rivers, gods, countries and well stoves are also taboo here. When you have sex, you should avoid these three taboos and conduct it in harmony with others at an appropriate time. "Women's Rules" says: "The place where bedrooms meet is also a good place to avoid", pointing out that sexual intercourse must be quiet in the bedroom, comfortable on the bed, neat bedding and pillows, and fresh indoor air.
Third, the preparation before sex:
The Sutra of the Plain Woman says: "The way to harmony lies in calm, peace of mind and harmony. All three qi are achieved, and the gods are one. " The so-called calm, peace of mind, is to be calm before the room is presented, to avoid irritability, anxiety, jealousy, anger and depression. The so-called harmony means that men and women are inspired by generate, tacit cooperation, sexy concentration, emotional contract and mutual encouragement. "Jade House Guide" says: "The way to surrender to women is to play slowly first, so that it can be a long time." This is the so-called "sexual preparation" and "sexual caress" stage in modern medicine. We should also follow this principle today, instead of rushing headlong into it.
Fourth, the appropriate time and direction of sexual intercourse:
"East Zi Xuan" said: "Couples make love, with their heads facing east in spring, south in summer, west in autumn and north in winter; One day is good, two days is bad; Midnight to noon is beneficial, and noon to midnight is harmful ... This theory involves the marginal sciences such as Yin and Yang, the five elements, human biological clock, medical climatology, heavenly stems and earthly branches and so on, and needs further exploration. According to foreign research, the best time for sexual intercourse is in the morning, when the secretion of androgen reaches its peak and the energy is the most abundant, and sexual intercourse can be more fun.
Five, the frequency of sexual intercourse:
"Medical Heart Prescription" said: "Twenty years old, often once every two days; Apply once every thirty or three days; Forty, four days; Give it once every five days; After 60 years, stop having diarrhea. " "Qian Jinfang" said: "Twenty-year-old people will be discharged on the fourth day; 30 years old, discharged on the eighth day; Those over 40 years old will be discharged on 16; Those who have reached the age of 50 will be discharged on the 20th; 60-year-old, that is, closed sperm, don't give it any more. If you are still physically strong, vent in January. " In fact, there should be no uniform standard for the frequency of sexual intercourse, which should vary from person to person. The general rule is this: the newly married couple have frequent sexual intercourse; Usually 2-3 times a week for a few months after marriage; With the increase of age, it will gradually decrease to 1-2 weeks, 1 time; Less times when the body is weak; It is human nature that the frequency of sexual intercourse increases after a long separation between husband and wife, but it should be properly controlled. In short, we shouldn't feel tired.
