Pregnancy is a transformative journey, and getting quality sleep during this time is crucial for both the mother and the baby. One of the most recommended sleep positions for pregnant women is sleeping on the left side. But why is this position so highly praised? Let’s explore the science behind it and how it can benefit you during pregnancy.
Looking to speak to Hanna from SleepyBelly, an expert in maternity sleep solutions, to learn more about how sleeping on your left side can improve circulation and reduce discomfort during pregnancy.
Why Sleeping on Your Left Side Matters
During pregnancy, your body undergoes significant changes, and your sleep position can have a direct impact on your comfort and health. Sleeping on your left side is often recommended by healthcare professionals, including midwives and obstetricians, for several reasons:

- Improved Blood Circulation: The inferior vena cava, a large vein that carries blood to your heart, is located on the right side of your body. Sleeping on your left side relieves pressure on this vein, allowing better blood flow to your heart, uterus, and kidneys. This improved circulation also benefits your baby by ensuring a steady supply of oxygen and nutrients.
- Reduced Swelling: Many pregnant women experience swelling in their legs and feet due to poor circulation. Sleeping on your left side can help reduce this swelling by promoting better blood flow.
- Better Kidney Function: This position helps your kidneys efficiently remove waste and fluids from your body, reducing the risk of water retention and swelling.
Expert Insights on Sleep During Pregnancy

We reached out to Monique Maitland from The Middee Society, a renowned midwife, to understand the importance of sleep positions during pregnancy. She emphasized, “Sleeping on your left side not only supports optimal blood flow but also helps alleviate common pregnancy discomforts like back pain and heartburn.”
Similarly, Beth Ryan from Birth With Beth shared, “Many of my clients find that using a pregnancy pillow while sleeping on their left side significantly improves their sleep quality. It’s a simple change that can make a big difference.”
Tips for Comfortable Left-Side Sleeping
While the benefits of sleeping on your left side are clear, it’s not always easy to maintain this position throughout the night. Here are some tips to make it more comfortable:
- Use a Pregnancy Pillow: A pregnancy pillow can provide the necessary support to your belly, back, and legs, making it easier to stay on your left side.
- Elevate Your Legs: Placing a pillow between your knees can help align your hips and reduce pressure on your lower back.
- Practice Good Sleep Hygiene: Create a relaxing bedtime routine and ensure your sleep environment is comfortable and conducive to rest.
