Sleeping on Your Back While Pregnant: What You Need to Know
Sleeping on your back while pregnant can have a significant impact on both your health and the health of your baby. While it may be comfortable to sleep on your back, it's not always the safest position, especially as your pregnancy advances.
Why is Sleeping on Your Back While Pregnant a Concern?
Research has shown that sleeping on your back in the second and third trimesters can compress a major blood vessel, reducing blood flow to your baby. This can lead to a range of complications, including:
- Stillbirth
- Low birth weight
- High blood pressure disorders
When to Stop Sleeping on Your Back While Pregnant
The American College of Obstetricians and Gynecologists (ACOG) recommends that women stop sleeping on their backs after 20 weeks of pregnancy. However, some studies suggest that the risk of stillbirth associated with sleeping on your back increases after 28 weeks.
What are the Risks of Sleeping on Your Back While Pregnant?
While sleeping on your back may not be the most comfortable position, it's not necessarily the most risky either. However, there are some potential risks to consider:
- Reduced blood flow to the baby
- Increased risk of stillbirth
- Low birth weight
- High blood pressure disorders
- Back pain
What are the Alternatives to Sleeping on Your Back While Pregnant?
If you're struggling to get comfortable while sleeping, try these alternative positions:

- Left side sleeping: This is often recommended as it can help reduce swelling in the legs and feet.
- Right side sleeping: This can be comfortable for those who have trouble sleeping on their left side.
- Stomach sleeping: This is generally not recommended after 16 weeks of pregnancy, as it can cause pressure on the vein that returns blood from your lower body to your heart.
- Using a pregnancy pillow: A pregnancy pillow can help support your body and reduce discomfort while sleeping.

- Use a full-length pregnancy pillow to support your body.
