Will slamming the door affect fetal development? Pregnant women should try to control their emotions and try not to get angry, because women's frequent anger during pregnancy not only affects their emotions, but also increases the risk of fetal heart problems. Medical experts have warned that the angry behavior of pregnant women will affect the fetal heart development and easily lead to heart problems.
Through research, researchers found that pregnant women who lose their temper, such as slamming the door, shouting loudly, throwing their rice bowls or even overeating, will affect the development of fetal heart and increase the risk of heart problems.
The researchers found that the heart rate of babies born to impulsive and aggressive mothers changed little. Medical experts believe that the change of heart rate is a sign of health, because it shows that the body can adapt to external changes and has strong adjustment ability. For example, different breathing patterns will affect the change of heart rate. But if the heart can't adapt to external changes, the risk of heart disease or infection will increase. Medical staff found that adults with small heart rate changes are more likely to suffer from heart disease.
In fact, previous studies have found that a series of physiological changes caused by pregnant women's anxiety can be transmitted to the fetus through the placenta, affecting the healthy development of the fetus and even affecting the intellectual development of the baby after birth. In severe cases, it can lead to fetal malformation and even abortion. This latest study found that hormones that lead to aggressive behavior can also be transmitted to the fetus through the placenta, which will affect the development of fetal cells. The study was led by researchers from the University of Sussex in the UK, who recruited 49 pregnant women aged 22 to 39 for the experiment. The conclusion of the experiment is that "uncontrolled and impulsive angry attacks will affect the physiological development of unborn babies." This will lead to an increased risk of heart disease. The researchers found that * * 22 pregnant women belong to the category of "irritability", accounting for almost half of the experimental population.
What factors will affect the fetal size 1 and genetic factors?
Of course, the size of the baby will be affected by the physical condition of the pregnant mother and the pregnant father, which is the role of genetic factors. If both the father and the pregnant mother are tall, the baby will be bigger. But if the pregnant mother is short and the father is tall, it's hard to say. As the saying goes, "Dad is short and Mom is short", it can be seen that the height of pregnant mother may have a greater impact on the baby.
2. Health status of pregnant women
If the pregnant mother is in poor health or suffers from certain diseases, the baby's nutritional supply will be affected and its size will also be affected. However, gestational diabetes is excluded, because pregnant mothers may have giant babies if they have gestational diabetes.
3. Living habits of pregnant women
Some pregnant mothers have bad habits such as drinking and smoking, which will worsen the uterine environment. For example, when a pregnant mother smokes, her blood vessels will contract, the oxygen and nutrition delivered to her baby will be reduced, and the normal development of her baby will be inhibited: alcohol will also be delivered to her baby through the umbilical cord, which will have a negative impact on her growth and development.
4. Eating habits of pregnant women
Adequate and balanced intake of various nutrients by pregnant mothers is an important guarantee for the healthy development of babies. If pregnant women are malnourished, the chances of giving birth to low birth weight babies are high. In addition, some bad eating habits, such as salty diet or excessive intake of high-calorie food, will hinder the baby's development.
5. The sex of the baby.
Generally speaking, a baby boy is slightly larger than a baby girl, because the skeleton frame of a baby boy is usually slightly larger than that of a baby girl. But this is not absolute. Some girls will be older than boys.
6. The baby's health.
If the baby can grow up healthily throughout pregnancy, it is generally not too short. However, if the baby suffers from some congenital diseases, such as congenital heart disease, it may lead to intrauterine growth retardation, thus making the baby smaller.
7. Number of pregnancies
In a twin or multiple pregnancy, the size of each baby will be smaller than that of a single pregnancy.
