Classification: medical and health care

Problem description:

I want to have a healthy baby and have a good birthday.

Analysis:

Medically speaking, it is best to get pregnant in May and June.

As we all know, children's gender, intelligence and birthday are closely related to their parents, but studies have proved that having children depends not only on their parents, but also on the climate. Recently, two scientists from the University of Mü nster, Germany, analyzed the birth records of 654.38 billion babies in 200 countries and regions around the world, and found that climate will affect children's date of birth, gender and intelligence.

10-22 degrees Celsius is the easiest time to get pregnant. Scientists believe that the easiest time to get pregnant in a year is when the sun shines 12 hours a day and the temperature is kept at 10-22 degrees Celsius. This climate is conducive to ovulation or a large number of ovulation. When the temperature exceeds 25 degrees Celsius, it will inhibit pregnancy. In the United States, for example, March and April in spring and 10 and1month in autumn are the most suitable months for pregnancy.

Although human beings have more sexual life in summer, women are less likely to get pregnant than in winter. On the one hand, the number of men has decreased in summer; On the other hand, women's eggs are more fertile in winter. At the same time, women who are pregnant in 65438+February and 65438+ 10 months have the highest probability of giving birth to twins and triplets.

Climate affects boys and girls, and special weather also affects the sex of the fetus. For example, from June 5438 to August 0977, the sex ratio of babies born in many parts of Britain was surprising: there were 5% more boys than girls. The reason is that scientists believe that this is related to the drought in Britain from June 65438 to June 65438. A heavy rain in mid-September, 1976, made the trace elements accumulated in the soil penetrate into groundwater and other water sources at a fairly high concentration, and then were absorbed by the human body through diet, resulting in the pairing of sex chromosomes in favor of the production of men. On the contrary, heavy fog appeared in London at 1952 and 12. After 320 days, more girls were born locally than boys.

In addition, women who are pregnant in April and May are more likely to give birth to boys, while women who are pregnant in 1 1 month and1February are more likely to give birth to girls.

As for eugenics, scientists believe that besides the quality of parents, it is also related to the activities of the sun. Two scientists from the former Soviet Union counted the births of some world celebrities and found that Darwin, Tolstoy, Turgenev and Ibsen were all born around 1825, when the solar activity was relatively stable. Because the peak of solar activity will disturb the earth's magnetic field, it is prone to magnetic storms and other phenomena, leading to abnormal climate, thus interfering with the biological rhythm of the fetus.

At the same time, scientists also found that most of the world celebrities and scientists who won the Nobel Prize in 1 tens of thousands were born in March and April. Moreover, the height of children born in this period is higher than that of children born in other months, especially compared with children born in 10- 12, the gap can reach 4 cm. This is because these children were conceived in May and June of the previous year. In spring, both men and women are full of vigor and vitality. At this time, the development of * * and eggs is better.

The other is about conception:

The best time to get pregnant

1, the best pregnancy age (24-27 years old)

Female reproductive period is 20-30 years old. Physiologically, female reproductive organs generally mature after the age of 20, and the development and maturity of bones will be around the age of 24. If you get pregnant before the bones mature, mother and child will compete for nutrition, which will affect the progress of mother's bone development.

But also because of uterine contraction weakness, abnormal fetal position, fetal dysplasia and so on. , will affect the baby's health. Therefore, it is reasonable for women to have children at the age of 24-27, preferably not over 30, especially not over 35. Because women are too old, the possibility of abnormal egg cells increases, and the rate of fetal malformation will increase after conception, which is not conducive to eugenics.

2, the best pregnancy season (late spring and early autumn)

The change of four seasons has obvious influence on human conception, pregnancy and fertility. Choosing an ideal pregnancy season is of great significance to maternal health and fetal growth and development. Experts believe that the best season for pregnancy is late spring or early autumn, that is, March-April or September-10.

American scientists investigated and analyzed 45,000 freshmen, and found that the excellent rate of children born in spring and autumn is 60% higher than that of children born in midsummer. Because the first trimester is the stage of fetal cerebral cortex formation, the temperature in summer is too high, pregnant women have heavy pregnancy reaction, poor appetite, less protein intake and high body consumption; In severe winter, the temperature is too low, there are few fresh vegetables, pregnant women often live indoors, have too little activity, and have insufficient fresh air supply, which makes them easy to catch a cold. These adverse climates will affect the development and intelligence of the fetus.

Pregnancy in late spring from March to April is the season of warm spring in bloom. At this time, the climate is mild and suitable, and rubella virus infection and respiratory infectious diseases are less prevalent. The diet and daily life of pregnant women are easy to adjust, so that the fetus has a stable development environment in the initial stage, which is most conducive to preventing teratogenesis. Adequate sunshine is another benefit of spring pregnancy, which can provide good sunshine conditions throughout pregnancy. Ergosterol in pregnant women's skin can be turned into vitamin D under the ultraviolet radiation of the sun, which promotes the absorption of calcium and phosphorus and is beneficial to the growth and development of fetal bones. In addition, sunlight on the skin can promote blood circulation, sterilization and disinfection, which is also of great benefit to the health of pregnant women.

Early autumn, September -65438+ 10 is also more suitable for pregnancy. Because September-10 is a crisp autumn, the climate is warm and comfortable, and the appetite for sleep is not affected. It is also the golden season of fruit production, which is very beneficial to the nutritional supplement of pregnant women and the development of fetal brain. The expected date of delivery of pregnant women is late spring and early summer, and the climate is mild. Adequate supply of auxiliary equipment is conducive to the recovery of pregnant women and the promotion of milk secretion. Children's clothes are gradually reduced, which is more convenient for nursing. In addition, at the turn of spring and summer, the sun is abundant, and the baby can have good lighting conditions, which is conducive to the calcification of the baby's growth and development and is not easy to suffer from rickets; In winter, the baby has gradually grown up and can avoid the epidemic peak of intestinal infectious diseases.

3, the best pregnancy time (ovulation)

The latest research results show that the pregnancy rate of * * * is higher on the day of ovulation and the first five days, and the "peak" of pregnancy rate is the day of ovulation. In order to increase the chances of pregnancy and improve the quality of the fetus, both men and women should abstain from sex for a period of time before ovulation, so that both sides have enough semen and blood. Too few or too many times of * * * are not conducive to pregnancy, and the short interval between * * * and the small amount of * * * are not conducive to pregnancy. Usually you need to abstain from sex for 3-5 days before ovulation to ensure a sufficient number of high-quality fertilization. In addition, it should be arranged as close as possible to the ovulation day. Because it is too early before ovulation, * * * stays in the female reproductive tract for too long, and it is too late after ovulation and the egg is too long, so the fertilization quality is poor. Both of these conditions affect the quality of fertilized eggs, which is not conducive to eugenics.

Women don't have to have sex to get pregnant, but sex * * * can increase the chances of pregnancy, because there is positive pressure in the uterus during sex * * *, and then it drops sharply to negative pressure, which is attractive in the uterus and beneficial to * * *. In addition, during sexual excitement, the medial 2/3 segment of * * * expands into the posterior * * * pool, and the lateral 1/3 segment contracts, which reduces the outflow of * * *, and the uterus rises when it is excited and decreases when it subsides, which is also beneficial for * * * to flow into the uterus from the * * * pool. Furthermore, in sexual excitement, * * * is decomposed into alkaline mucus, which makes the PH value of * * * normal acidic environment rise, which is beneficial to the survival and activities of * * *.
