Pregnant women's belly will increase with the increase of gestational age, and there are many inconveniences and precautions in daily life, such as sleeping. Choosing to sleep on the left side is beneficial for both pregnant women and fetuses, but what we are referring to here is not 90 degree side sleeping. So, what are the hazards of 90 degree sleeping for pregnant women?

If pregnant women choose to sleep at 90 degrees, they will feel very uncomfortable while sleeping, and this position is difficult to maintain for a long time, which will affect the quality of their sleep and also affect the fetus. When choosing to sleep on the left side, you should maintain an angle of around 15-30 degrees, which will make sleeping more comfortable.
Pregnant women should sleep in different positions at different gestational weeks. Let's take a look together!
1. Early pregnancy. During this period, there is not much external pressure, so pregnant women can freely choose which sleeping position to sleep in. The key is to prioritize the comfort of the pregnant woman. However, if pregnant women are used to sleeping on their stomach, it is best to change it.
2. Mid pregnancy. In mid pregnancy, the belly will gradually grow larger, and protection of the abdomen is important at this time. Pregnant women can adopt a lateral sleeping position, which is not only more comfortable but also avoids abdominal pressure. If a pregnant woman's lower limbs are heavy, she can adopt a supine position or use a pillow to elevate her lower limbs.
3. Late pregnancy. During this period, the sleeping position of pregnant women is very important, and it is best to choose the left side position, which is beneficial for the growth and development of the fetus.
