Will the sleeping position of pregnant women affect the fetus? What is the most correct sleeping position?

Pregnant women need to pay more attention to various matters during pregnancy. Among them, sleeping posture is also worthy of everyone's attention. So, will the sleeping position of pregnant women affect the fetus?

Will a pregnant woman's sleeping position affect the fetus?

In the late pregnancy, the uterus enlarges and slightly rotates to the right. If you maintain the right side lying position for a long time, the blood flow in the uterine artery may be affected, affecting the blood supply to the fetus. It may also compress the inferior vena cava, affect the amount of blood returning to the heart, and cause orthostatic hypotension. Therefore, the left side lying position is recommended in the late pregnancy. For the early and mid-pregnancy, there are no special requirements for sleeping positions. You can change a few positions more often without compressing the abdomen and keep the fetal movement and heart rate normal.

What is the most correct sleeping position?

Early pregnancy (1-3 months)

Sleep however you are comfortable! In the early stages of pregnancy, the fetus develops in the uterus and is still in the mother's pelvic cavity. Direct external pressure or self-pressure will not be very heavy, so the sleeping posture of pregnant women can be free, as long as they adopt a comfortable position, such as supine or side-lying.

Second trimester (4-7 months)

Pay attention to protecting your abdomen! The abdomen will bulge in the middle of pregnancy, so some bold sleeping positions should be restrained. Avoid direct external force. If a pregnant woman has too much amniotic fluid or is pregnant with twins, she should sleep in a side-lying position. If a pregnant woman feels heavy in her lower limbs, she can lie on her back and slightly raise her lower limbs with a soft pillow.

Late pregnancy (8-10 months)

The lying position is particularly important. The lying position of pregnant women is important to the safety of themselves and the fetus. It is advisable to adopt the left side lying position, which can correct the right rotation of the enlarged uterus, reduce the pressure of the uterus on the abdominal aorta, improve blood circulation, increase blood supply to the fetus, and is beneficial to the growth and development of the fetus. However, it is not advisable to adopt the supine position, because in the supine position, the huge uterus compresses the inferior vena cava, reducing the amount of blood returning to the heart and cardiac output, and causing hypotension. Pregnant women will feel dizzy, palpitations, nausea, and accompanied by symptoms such as pale complexion, weakness in the limbs, and cold sweats. If the above situation occurs, you should immediately lie on your left side. Your blood pressure will gradually return to normal and the symptoms will disappear.
