A smart and healthy child is an important element of a happy family, and choosing the best time of the year to have a child can have a significant impact on a woman’s ability to conceive and develop a healthy fetus. Many studies have shown that there is a clear relationship between the child’s congenital condition and the season of conception. Spring and March is the season when human life is most adapted to nature and is the best season for conception. The mild and comfortable climate in March awakens the body that has been suppressed for months by the cold winter, and human sexual activity increases significantly. From the male perspective, the quality of sperm in men is better in winter and spring; while women have the highest success rate in pregnancy in spring, followed by summer and winter, and the lowest in autumn. Scientific investigations in Israel, England and Alaska, USA have all theoretically confirmed this view. In addition, the middle of pregnancy is in the summer or autumn, when there are relatively few viral diseases that seriously affect the development of the fetus, and pregnant women are less likely to suffer from colds and other diseases, and the fetus is safe; in addition, the middle of pregnancy is in the summer and autumn harvest season, when there are more fruits and vegetables and eggs and meat, and both mother and child can get comprehensive nutrition. For these reasons, young couples preparing to conceive should try to plan their conception to create some better conditions for their future little ones from the very beginning. In this spring, the work of “planting” is of course inseparable from good physical conditions: 1, first of all, maintain a bright mood like spring, emotional happiness, avoid negative emotions on the body’s endocrine influence; 2, self-examination, to exclude unsafe factors, such as the first three months of pregnancy should stop smoking and alcohol, before pregnancy should stop long-term The first three months of pregnancy, you should stop smoking and drinking, stop long-term contraceptive pills for more than 6 months before pregnancy, no recent history of colds and other infectious diseases or X-ray examination, tiredness and fatigue are not suitable for pregnancy, etc. 3. Some diseases must be actively treated and then considered for conception after they are cured. Pregnancy can cause many physiological changes, which can trigger or aggravate some potential pathologies in the body, such as endocrine and dietary changes that make pregnant women susceptible to oral diseases, endocrine and fetal influences that can aggravate kidney diseases and hypertension, which can cause mothers-to-be to suffer, and may affect the safety of childbirth.
