The Best Sleep Positions in Pregnancy
The best sleep position in pregnancy is on your side, especially in the third trimester, with a pillow between your knees and under your bump for support. The left side is often recommended because it supports blood flow to the baby, though either side is fine. It's best to avoid sleeping flat on your back or stomach later in pregnancy. A pregnancy pillow and a calming bedtime routine both help.
As your pregnancy progresses, getting comfortable at night gets harder. Finding the right sleep position can help you get the rest you need.
Why is good sleep important in pregnancy?
Good sleep matters for both mother and baby. Too little can affect your hormones, mood, and energy, and leave you more prone to exhaustion. Simple steps, like limiting late-night screens and building a calming evening routine, are worth the effort.
Sleeping on your left side: circulation and less swelling
Sleeping on your left side supports blood flow from the lower body back to the heart, which can help reduce swelling and soreness. It's often recommended in late pregnancy because it supports the flow of blood to the baby through the placenta and umbilical cord.
Sleeping on your right side: also fine
The right side is fine too. Some people with lower-back or digestive discomfort find it more comfortable, and it still supports circulation. Current guidance is that either side is suitable in late pregnancy, so go with whichever feels best. The key is simply to sleep on your side rather than your back.
Avoid sleeping on your stomach (and your back) later on
As your abdomen grows, sleeping on your stomach can cause strain and compression, and back-sleeping late in pregnancy can put pressure on major blood vessels. Instead, sleep on your side with a pillow between your legs or under your bump to stay comfortable and supported.
Invest in a good pregnancy pillow
A pregnancy pillow can support your belly, back, and legs while you sleep or rest. Designed around the body's contours, it eases pressure points along the spine and neck and keeps you comfortable whichever way you settle, helping you wake with fewer aches.
Relax before bedtime for better sleep
A pre-bed wind-down can make a real difference. Techniques like deep breathing, progressive muscle relaxation, guided imagery, and hypnobirthing, plus learning about your birth through a childbirth preparation class, can help ease stress that disrupts sleep. Try setting aside 15 minutes before bed: close your eyes and focus on your breathing for five minutes, alone or with a partner. Prenatal yoga can help too. Whatever you choose, doing it consistently improves your sleep over time.
