We also recommend avoiding sleeping on your back while pregnant. With the changes in your hips and abdomen, sleeping on your back can cause pain and breathing issues.
It can also lead to issues with your digestive system, including heartburn or nausea. Along with that, sleeping on your back during pregnancy can lead to hemorrhoids, low blood pressure, and a low amount of blood and nutrition to your heart and baby.
When you sleep on your back, your growing uterus and baby put pressure on your intestines and vena cava. The vena cava is a main vein which is essential for transporting blood throughout your body.
Along with all this, some studies suggest that sleeping on your back can actually lead to serious issues with pregnancy complications. If you sleep on your back, you may be up to 5.8% more likely to experience stillbirth after 28 weeks.
Does this mean if you wake up in the middle of the night on your back that you are in trouble? Not necessarily, but you really should strive to prevent this. As we’ll explain later on, there are specific pillows that can help with this.
