The answer depends largely on how far pregnancy has progressed. According to ACOG, lying flat on the back during the second and third trimesters can compress a major blood vessel and may cause dizziness or affect blood flow.
Can I Sleep On My Back During Pregnancy?
Early in pregnancy, sleeping on your back is generally not a concern. As the uterus grows, however, prolonged flat-on-the-back sleeping may become uncomfortable.Dr Ritambhara Bhalla, Associate Director – Department of Gynecology and Obstetrics at Cloudnine Group of Hospitals, Chandigarh, explains, “It depends on the stage of pregnancy.” She adds that “early in pregnancy, sleeping on your back is generally not a concern”, while later pregnancy is different as the growing uterus can place pressure on major blood vessels.
The NHS advises women to avoid going to sleep on their backs after 28 weeks because research has linked this position with an increased risk of stillbirth. Side sleeping is therefore recommended during the later stages of pregnancy.
Is Left-Side Sleeping Better?
You may have heard that pregnant women should sleep only on their left side. However, both sides are acceptable.Dr Bhalla explains, “You do not have to sleep exclusively on your left side. Both the left and right sides are acceptable.”
The priority is to make side sleeping comfortable and sustainable rather than becoming anxious about maintaining one specific position throughout the night.
What If You Wake Up On Your Back?
Occasionally waking up on your back is not a reason to panic. Dr Bhalla advises, “Simply turn onto your side and get comfortable again.”She also emphasises that “the goal is not to maintain one perfect position throughout the night”. The important point is to make side sleeping your usual position when going to sleep, particularly after 28 weeks.
