Expectant mothers are extremely excited when they are pregnant with their baby. However, as the weeks went by, the belly got bigger and bigger, and even simple sleep became a problem that troubled the expectant mother. If you lie on your back, you will feel uncomfortable; if you lie on your side, you are afraid of pressing the baby; if you lie on your stomach, it is even more unscientific.
The importance of sleeping position during pregnancy
After a woman becomes pregnant, the fetus gradually grows in the womb. The uterus, which originally resembled a pear-shaped inverted uterus, became the size of a watermelon at full-term pregnancy. The weight of the uterus also increases from 50 grams in non-pregnancy to 1000 grams in full-term pregnancy.
As the uterus and fetus grow, the sleeping posture of pregnant women becomes more and more important, especially in the third trimester of pregnancy, that is, between 7 and 9 months of pregnancy. Poor sleeping posture will not only affect the contraction of the uterus, but also affect the position of the uterus. It will increase the pressure of the pregnant uterus on surrounding tissues and organs, affecting the blood flow of the uterus and placenta.
The fetus exchanges gases and substances with the mother\’s body through the placenta, obtains oxygen and nutrients, and excretes carbon dioxide and waste. Adequate placental blood flow is crucial to fetal growth and development.
Choice of sleeping position
It is better for normal people to sleep on their right side, because the heart is located on the left side of the chest. This sleeping position can reduce the pressure on the heart. So, what is the best sleeping position for pregnant women?
