Can I sleep on my back during pregnancy?

After a woman becomes pregnant, her body will undergo major changes, and many of her living habits will also change compared to before. During the second trimester of pregnancy, many girls are accustomed to sleeping on their backs, which is a very bad behavior. Sleeping on your back will not only put pressure on the fetus, preventing it from moving normally, but will also put pressure on the woman's breathing, causing her to snore at night. So, how should pregnant women sleep during the second trimester? What kind of posture should be adopted?

1. Lying on your back is very harmful

Many expectant mothers in the second trimester believe that people can sleep on their side or on their back at will, but as their bellies grow, they worry that sleeping on their side will squeeze the fetus, so they simply adopt a supine position. Lying on your back can also avoid compressing the heart. This sleeping position was adopted before pregnancy, and it will definitely be a safe sleeping position after pregnancy.

Experts say that contrary to what these expectant mothers think, the uterus does not increase significantly in the early stages of pregnancy, and lying on your back has little effect on the fetus. However, when entering the second trimester, the body position during this period can directly affect the blood flow to the uterus, especially the supine position will have a series of adverse effects on pregnant women and fetuses.

2. Not suitable for right sleeping

Many people believe that the heart is generally on the left side of the human body, so it is best to sleep on the right side because this can reduce the pressure on the heart. Experts say that for pregnant women, especially those in the second trimester, the situation is just the opposite!

As the pregnancy progresses, the expectant mother's uterus continues to grow and even occupies the entire abdominal cavity. If you sleep on your right side at this time, the nearby tissues and organs will be squeezed and the uterus will 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, and the blood vessels in the mesentery that supply nutrients to the uterus will also be pulled, affecting the oxygen supply to the fetus, which can easily cause chronic hypoxia and suffocation of the fetus and lead to death.

3. Left-side sleeping is the most suitable

Since lying on your back or on your right side is not suitable for expectant mothers in the second trimester? So what is the most correct sleeping position?

Experts say that the best sleeping position for pregnant women is lying on the left side, especially in the second trimester. The benefits of this lying position are as follows:

1. Sleeping in the left lateral position can turn the right-rotated uterus to an upright position, which can reduce the pressure of the pregnant uterus on the aorta and iliac arteries, thereby reducing the resulting fetal position and delivery abnormalities.

2. The left side lying position allows the expectant mother's uterus to maintain normal tension to ensure blood perfusion of the placenta. It can also avoid the uterus from compressing the veins of the inferior cavity, increase the amount of blood output of the pregnant woman, and make it less likely for the pregnant woman to develop lower limb edema and varicose veins of the lower limbs, which is beneficial to reduce premature birth, fetal maldevelopment and other diseases. It is beneficial to the healthy growth and development of the fetus and eugenics.
