The uterus where the baby lives is generally right-handed, so the doctor will recommend the pregnant mother to sleep on the left side to reduce the pressure of the uterus on the arteries and allow the placental blood supply to be normal. In general, pregnant women are prone to lower extremity edema and varicose veins, which may seriously affect the development of the fetus. This is because the weight of the fetus will oppress the large veins of the pregnant mother and affect the blood flow of the pregnant mother from the legs and feet to the heart. At this time, if the pregnant mother is able to sleep on the left side, the above symptoms will be relieved. So, what are the benefits of using maternity pillows? 1. Help pregnant women maintain a sleeping posture on the left side As the fetus in the abdomen grows up, pregnant mothers are also getting harder and harder. Especially when sleeping, I often toss and turn, making it difficult to fall asleep. In order to maintain the sleeping position on the left side recommended by the doctor, pregnant mothers often feel more anxious. At this time, the pregnant woman pillow can effectively help the pregnant mother to maintain the sleeping position on the left side, reducing the heaviness of the abdomen and the soreness of the back. 2. Support the abdomen and reduce the pressure on the abdomen When a pregnant woman sleeps on her side, there is a gap between the abdomen and the bed, and a pregnant woman pillow can bridge this gap and give the pregnant woman a relaxed sleep state.
