When the pregnancy belly begins to grow, sleeping can become a nightmare, especially in the last pregnancy. Finding a comfortable position can be quite an odyssey.
In fact, there is a position that is better than any other so that you can sleep during pregnancy and also, that you feel comfortable throughout the rest.
The left side
Sleeping on the right side is not a good option because there is the vena cava which is the largest vein in the body that circulates with a significant flow of blood. When a pregnant woman lies on the left side, this pressure of the weight on the vein is avoided and the blood supply to the placenta is favored and more oxygen and nutrients are provided for the baby.
Ideally, when lying in bed on your left side, keep the same direction and angle between your shoulders and hips to keep your muscles and spine relaxed. Although there are no studies that can say that sleeping on the right side is bad for the baby, sleeping on the left side is known to be a better option by far for the pregnant woman and her baby.
Face up is not an option
If you lie down while pregnant on your back, you will not feel comfortable and the weight of the uterus will fall on the back, the intestines and the inferior vena cava. Sleeping in this position can make your back ache, have digestive problems (constipation), get hemorrhoids ... It can even be dangerous during the last trimester of pregnancy if it is a risk pregnancy.
If you find it difficult to sleep due to the size of your belly, remember that pillows are your best ally and that if you put them between your legs you will feel more comfortable.
