When sleeping/lying on your back the baby and womb put pressure on the main blood vessels that supply the uterus and this can restrict blood flow/oxygen to the baby.
Sleeping On Your Back During Pregnancy:
The inferior vena cava is a large blood vessel that carries blood back and forth between your heart and your uterus.
As your belly grows during pregnancy, sleeping on your back puts pressure on this important vessel.
Compressing it can make you feel dizzy and reduce blood flow to your baby.
This can be pretty serious.
You want to make sure that the blood inside it is flowing as freely as possible for the health of both you and your baby.
What if I accidentally sleep on my back while pregnant?
