What is the best sleeping position when you are four months pregnant? What are the dangers of improper sleeping posture?

In the second half of pregnancy, because of the burden on the stomach, if the pregnant woman follows the normal sleeping position, it will not conform to the physiological and anatomical structure of the human body. So what is the best sleeping position during pregnancy?

What is the best sleeping position during pregnancy?

Experts say that the second half of pregnancy is also divided into the first half and the second half. At four months of pregnancy, the uterus has not yet come out of the pelvic cavity, so the positions and postures often adopted are more common. Generally, after the fifth month or after 28 weeks, because the uterus gradually grows larger, if the mother adopts the supine position for a long time, it will compress the inferior vena cava.

Experts say that the best sleeping position for pregnant women in the second trimester is lying on the left side. Lying on the left side can turn the right-rotated uterus to an upright position, thereby reducing the resulting fetal position and delivery abnormalities. It can also prevent the uterus from compressing the veins in the inferior cavity, increase the amount of blood output in pregnant women, reduce edema, improve the blood perfusion of the uterus and placenta, help reduce premature birth, and promote the healthy growth and development of the fetus and eugenics.

If the following conditions occur during pregnancy, you should be alert:

1. Persistent severe vomiting may be caused by hyperemesis gravidarum or poor liver function.

2. Vaginal discharge, bleeding or amniotic fluid may be caused by early rupture of membranes or infection.

3. Chills, fever, burning sensation in urine or diarrhea may be caused by infection.

4. Changes in fetal movement. After the initial feeling of fetal movement, the fetal movement suddenly disappears or the form or amount of fetal movement changes, which means that the fetus may be in danger or the fetus has died in the uterus.

It can be seen that the sleeping position of expectant mothers has a great impact on the health of the fetus, so for the health of the fetus, expectant mothers must choose a good sleeping position!

What are the dangers of improper sleeping posture during pregnancy?

1. Supine sleeping position: When lying on your back, the enlarged uterus compresses the abdominal artery, which reduces the pressure of the uterine artery and affects the blood supply to the uterus, thereby reducing the blood supply to the placenta. Insufficient blood flow to the uterus causes the ischemic placenta to release a large amount of renin. Renin enters the maternal blood circulation, which can lead to increased arterial pressure, making it easy to develop and aggravate pregnancy poisoning.

2. Sleeping on the right side: Lying on the right side will cause the uterus to rotate to the right to varying degrees. This will put the ligaments and mesentery that maintain the normal position of the uterus in a state of tension. The blood vessels in the mesentery will be pulled, affecting the blood supply to the fetus, causing chronic hypoxia of the fetus. In severe cases, it may cause fetal suffocation and death.
