Safe sleep in pregnancy - #SleepOnSide
In the past five years there have been five scientific studies across five countries about women's sleeping position during pregnancy. These studies have shown that that women who go to sleep on their back have a higher chance of having a stillborn baby compared women who go to sleep in another position.
In these studies, the chance of having a stillborn baby ranged between 2.5 to 8 times greater for women who went to sleep on their back. The research suggests that 1 in 10 stillbirths occurring in late pregnancy (after 28 weeks' gestation) could potentially be avoided if women did not go to sleep on their back during this time.
More research is needed to work out the best ways of comfortably avoiding back sleeping, and also how avoiding going to sleep on the back affects other pregnancy outcomes.
In the meantime, women are being advised to settle to sleep on their side for any episode of sleep, including:
- Going to sleep at night
- Returning to sleep after any awakenings
- Day time naps
Please contact your midwife or doctor if you are concerned about your sleep position or anything else about your pregnancy.
