Natural childbirth is a normal physiological process of human reproduction and a female instinct. A woman who is healthy, of the right age, and who has a normal full-term pregnancy will have a natural delivery when the time is right. Of course, during labor, due to uterine contractions, the mother will have abdominal pain and quite severe, which will bring physical pain and mental tension. But these are temporary and bearable. Therefore, for the vast majority of healthy and normal pregnant women, natural childbirth is not a problem. What are the advantages of natural childbirth? First, for the fetus, the regular contraction of the uterus during delivery can make the fetal lungs get exercise, which is conducive to the establishment of neonatal respiration after birth and promotes lung maturation, and pulmonary hyaline membrane disease seldom occurs after birth; uterine contraction and the extrusion of the birth canal during delivery can squeeze out the amniotic fluid and mucus from the fetal respiratory tract, so that the incidence of neonatal wet lungs and aspiration pneumonia is greatly reduced; immunoglobulin can be used by mothers to protect their babies from the risk of pneumonia during the natural delivery process. immunoglobulin can be transmitted from the mother to the fetus during natural delivery, while cesarean section children lack this process of acquiring antibodies, so newborns born naturally have stronger resistance. Second, for newborns, natural delivery of the child is rarely born after the birth of pulmonary hyaline membrane disease. Pediatric head congestion can elevate the brain respiratory center of panic, easy to inspire the birth of the fetus breathing and crying, beneficial to the newborn after birth to quickly establish normal respiration; due to the brain suffered vaginal compression of the child’s intellectual development in the future will be beneficial. Third, for the mother, natural childbirth is conducive to lactation, before the delivery of the fetus, the mother’s body secretion state will change, ready for lactation. As early as 1977, it has been known that beta-endorphin can promote the release of prolactin. By 1979, researchers found that beta-endorphin levels in the mother’s body increase during labor. In 1996, a study by Swedish scholars showed that prolactin was released in a pulsatile manner during breastfeeding in vaginal births compared to cesarean births two days postpartum, with the amplitude and frequency correlating with the duration of breastfeeding. In contrast, in cesarean section mothers, prolactin release levels did not increase significantly after 20-30 minutes of breastfeeding. Italian scholars have shown that β-endorphin levels were significantly higher in colostrum of vaginally delivered mothers than in cesarean section mothers on day 4 postpartum. It is possible that the effect of this opiate in breast milk induces dependence on breast milk in infants. From the above, it is clear that the behavior of mothers and newborns is influenced by a variety of hormones released during childbirth. At the same time, the above study also reveals the mystery of the newborn’s ability to locate the mother’s breast within the first hours after birth. In other words, the hormones released by the mother during labor are not eliminated within one hour after delivery, and they have their own specific functions for the mother and the newborn. Fourth, for the mother, the lower part of the uterus thins and the upper part thickens during labor pains, and the mouth of the uterus dilates. This change makes the mother’s postpartum uterine contraction force increased, which is conducive to postpartum discharge, uterine recovery, and reduce postpartum hemorrhage. It is also free from the influence of anesthesia and surgery, and the postpartum recovery is fast. It can be seen that vaginal delivery is the normal way of delivery. Pregnant women should be well prepared mentally and psychologically after pregnancy, and if there are no abnormalities, they should strive for vaginal delivery for the sake of the health of the mother and the baby. For the vast majority of healthy pregnant women, natural childbirth is both easy and safe. Therefore, when you have the conditions for natural delivery, you should follow your doctor’s instruction and choose vaginal delivery as a natural and safe way of delivery, which is beneficial to the health of both mother and baby. This is the advice that a large number of clinicians give to pregnant women.
