After how many weeks of pregnancy, can a pregnant mother not sleep on her back?

After 9 weeks of pregnancy, you should not lie flat. Generally, it is necessary to insist on sleeping on the left side from the second trimester, because sleeping on the left side can provide blood and oxygen to the fetus.

I don't think pregnant mothers can sleep on their back after 18 weeks, because sleeping on their back will make the baby in the belly very uncomfortable.

At 20 weeks, because the belly is relatively large at this time, it will be very uncomfortable to sleep on your back, and you can't sleep.

It is best to sleep on your side, on the left side and on the right side, to promote blood circulation and not make the baby feel oppressive.

In general, it is best for women not to sleep on their back after five months of pregnancy. After the second trimester, the fetus will grow bigger and bigger, and the pregnant woman's belly will become more and more obvious, and the enlarged uterus when lying flat is easy to compress the inferior vena cava, which can easily cause poor blood return and cause low blood pressure in pregnant women. At the same time, the baby in the belly will also be affected by the lack of blood supply and hypoxia.

Therefore, after five months of pregnancy, it is recommended that pregnant women sleep on their sides, either on the left side or on the right side, mainly in the left side position. Pregnant women can maintain the normal blood flow of the uterine arteries, and it is not easy for the uterus to compress the aorta and iliac arteries, and sleeping on the left side is also good for the growth and development of the baby. In the early stages of pregnancy, the fetus is still relatively young, so you can sleep in a casual position, and take whatever position is comfortable.

But you can't sleep on your stomach, so as not to press the fetus in your belly.

Precautions for first-trimester care.

1. No contact with tobacco and alcohol: Not touching tobacco and alcohol not only means that you do not smoke or drink, but also include not staying in a smoking environment for a long time, and passive smoking will also cause harm to children.

2. Brush your teeth frequently: Due to morning sickness, expectant mothers need to brush their teeth frequently to avoid their teeth being destroyed by vomit residues; In addition, expectant mothers who have just become pregnant like to eat sour foods, which are the most likely to spoil their teeth.

3. Coping with vomiting: If the expectant mother always wants to vomit after eating, then she needs to prepare a towel and mouthwash with her. If the expectant mother hasn't told her boss and co-workers about her pregnancy, then she should come up with a convincing excuse in case the co-worker helps you when you're not feeling well.

Some female friends usually like to sleep on their backs, and they feel very comfortable to sleep like this, especially in winter, lying on their sides will always make their backs cold. After pregnancy, they still haven't broken this habit, but they don't know that this habit is extremely bad for the baby. So, is it not recommended to lie flat for a few months of pregnancy?

Generally, it is no longer recommended that pregnant mothers lie down to sleep at about five months of pregnancy, because as the baby grows up, the enlarged uterus will compress the inferior vena cava when lying down, and the compression will cause poor blood reflux, which will cause low blood pressure in the pregnant mother. In addition, the baby in the belly will also have insufficient blood supply due to poor blood**.

Therefore, it is recommended that pregnant mothers after five months should sleep in the left decubitus position, and the right decubitus position is also fine, mainly in the left decubitus position. Even if the baby in the womb is not five months old, it is recommended that pregnant mothers sleep in a side-lying position, which is good for the baby's growth. However, during the period of 1-3 months of pregnancy, pregnant mothers can sleep in a casual position, how comfortable and how to sleep, but they cannot sleep on their stomachs or with things in their arms, which will oppress the baby in the belly.

Pregnant mothers choose the left lying position to sleep, which can maintain the normal blood flow of the uterine artery, which is good for slowing down the compression of the aorta and iliac artery by the uterus that grows up due to pregnancy, and can ensure the blood supply of the placenta to the baby.

Pregnant women need to be careful in all aspects of their lives during pregnancy in order to facilitate the better development of the fetus, but with the development of the fetus, the body of pregnant women is becoming more and more bulky, so at this time we must pay attention to travel safety, when sleeping, the sleeping position is also particular, so can pregnant women take a lying position to sleep? Let's take a look.

How to sleep more comfortably in the second trimester

It is best for pregnant women to use the sleeping position of lying on the left side, and you can choose to switch left and right, the reason why you choose the sleeping position on the left side is to eliminate the fatigue and muscle tension of pregnant women, and also improve the sleep quality of pregnant women. In addition, lying on the left side will not compress the large blood vessels in the abdomen of the pregnant woman, and avoid the condition of blood return, so that sleeping will not be too difficult.
