When you lie belly-up, the weight of your uterus can compress a major blood vessel, called the vena cava, disrupting blood flow to your baby and leaving you nauseated, dizzy, and short of breath. The best way to sleep during the second half of pregnancy is on your side.
Herein, why is it important to sleep on left side during pregnancy?
Because your liver is on the right side of your abdomen, lying on your left side helps keep the uterus off that large organ. Sleeping on the left side also improves circulation to the heart and allows for the best blood flow to the fetus, uterus, and kidneys.
Can you lay on your right side while pregnant?
Lying on your right hand side is much better than sleeping on your front or back during the later stages of pregnancy, but is still not as good as sleeping on your left. This is because, sleeping on your right hand side can puts pressure on your liver which most Doctors would prefer you to avoid.
What will happen if you lay on your stomach while pregnant?
It's fine to sleep however you're most comfortable during pregnancy. It's unlikely you'll be able to sleep comfortably on your stomach as your belly grows, but you can sleep face down for as long as it suits you. That's why by mid-pregnancy, most pregnant women are sleeping on their side.
