***Sleeping on your side***
There have been several international research studies about women’s sleeping position during pregnancy. These studies have shown that women who go to sleep on their back have a higher chance of having a stillborn baby compared women who sleep on their backs after 28 weeks of pregnancy.
Research shows that going-to-sleep on your side from 28 weeks of pregnancy can halve your risk of stillbirth, compared to going-to-sleep on your back.
After 28 weeks of pregnancy, lying on your back presses on major blood vessels which can reduce blood flow to your uterus and the oxygen supply to your baby.
Either your left or right side is fine. It’s normal to change position during sleep and many pregnant women wake up on their back. It happens a lot. The important thing is to start every sleep lying on your side (both for daytime naps and at night). If you wake up on your back, just roll over on your side.
Go to sleep on your side for anytime you sleep:
- Going to sleep at night
- Returning to sleep after any night wakenings
- Naps during the daytime
