Pregnancy is a transformative journey filled with anticipation, emotion, and physiological change. As your body nurtures new life, sleep becomes both more essential and increasingly elusive.
For expectant mothers—particularly those accustomed to luxury, wellness, and comfort—the quality of rest takes on new meaning. While nutrition and activity often get the spotlight, your sleeping position during pregnancy can be just as vital to your health and your baby’s development.
Whether you're in the early weeks or approaching your third trimester, understanding how to sleep safely and comfortably can significantly elevate your prenatal well-being.
How to Sleep During Pregnancy?
The way you rest during pregnancy evolves with each trimester. In the early stages, most sleeping positions are relatively safe, but as the baby grows and the uterus expands, certain postures can compress major blood vessels, affect circulation, and cause discomfort.
For those seeking a balance of support, alignment, and peace of mind, attention to sleeping position during pregnancy becomes not just a suggestion but a necessity. It’s not merely about avoiding discomfort; it’s about optimising blood flow, preventing back pain, and promoting fetal health.
5 Best Sleeping Positions During Pregnancy
Here are the most recommended ways to sleep during pregnancy, balancing maternal health and comfort:
1. Left-Side Sleeping (SOS – Sleep on Side)
- Widely endorsed by medical professionals, sleeping on the left side improves circulation and ensures maximum blood flow to the placenta.
- This sleeping position during pregnancy reduces pressure on the liver and enhances kidney function, helping minimise swelling in the legs and ankles.
2. Supported the Left Side with Pillow Placement
- Use a full-length or wedge pillow to support your belly, knees, and back.
- Especially useful in the second and third trimesters, this sleeping position during pregnancy prevents unwanted rolling and relieves pressure points.
3. Elevated Upper Body
- For those suffering from pregnancy-related heartburn, slightly elevating the upper torso with pillows or an adjustable bed can reduce symptoms.
4. Semi-Fetal Position
- Curling your legs towards your body (not tightly) while sleeping on your left can alleviate back pain and improve breathing.
5. Left Side with Bent Knees
- This variation keeps the spine aligned and enhances comfort, particularly when paired with a firm, pressure-relieving mattress.
Incorporating the right latex foam or memory foam mattress is essential—premium options with targeted support and responsive materials can complement these positions to deliver truly restorative sleep.
5 Worst Sleeping Positions to Avoid During Pregnancy
Some positions, though comfortable in normal circumstances, can compromise maternal or fetal health during pregnancy. Here are some wrong sleeping positions during pregnancy to steer clear of:
1. Sleeping on the Back (Especially After 20 Weeks)
- It can compress the inferior vena cava and reduce blood flow to the baby.
- It may cause dizziness, low blood pressure, and breathing difficulties.
2. Stomach Sleeping
- While possible during early pregnancy, it's impractical and uncomfortable beyond the first trimester.
- Puts undue pressure on the uterus and may restrict breathing.
3. Reclining Flat on the Back
- Increases the risk of stillbirth and causes backaches or digestive issues.
4. Twisted Spine Position
- Lying with the torso facing one direction and the hips another can strain the spine and abdominal muscles.
5. Unsupported Side Sleep on a Soft Mattress
- Without proper spinal alignment, even a "correct" position can cause discomfort.
- Mattresses lacking zoned support or contouring can exacerbate issues.
This is where high-end sleep solutions, like memory foam and latex foam mattresses, can elevate prenatal comfort dramatically.
Which Side to Sleep (Left vs. Right) During Pregnancy for Better Comfort?
A question that arises often is: which side to sleep on during pregnancy—left or right?
The answer lies in circulation. Sleeping on the left side is typically considered optimal. It allows for better blood flow to the placenta and reduces pressure on the liver. It also supports kidney function, minimising fluid retention.
Sleeping on the right side is not dangerous, but it may compress the liver and slightly restrict blood flow when compared to the left. For this reason, alternating between sides is acceptable, but if choosing one, left is best.
Tips to Sleep Better During Pregnancy
Pregnancy demands a deeper kind of rest—one that nurtures both body and mind. From choosing the right mattress to creating a calming nighttime ritual, these tips can help you sleep more soundly throughout your journey.
1. Invest in a High-Quality Mattress
Choose one that offers pressure relief, spine alignment, and responsive comfort—essentials for your evolving body.
2. Use Pregnancy Pillows
Strategically place them between the knees, under the belly, or behind your back for added support.
3. Maintain a Calm Bedtime Routine
Dimming lights, reading, or meditative breathing can help calm both body and mind.
4. Limit Screen Time Before Bed
Blue light disrupts melatonin levels, affecting sleep onset.
5. Stay Hydrated, but Time It Right
Drink fluids throughout the day but reduce intake close to bedtime to avoid frequent urination.
When combined with cutting-edge sleep technologies like Sleep-ID, which personalises mattress recommendations based on your posture and body type—even these small habits can lead to significant sleep improvements.

FAQs
1. Can I sleep on my back during pregnancy?
It’s best avoided after the first trimester. Sleeping flat on your back can compress major blood vessels, potentially reducing circulation to your baby and causing symptoms like dizziness or shortness of breath.
2. Why should I avoid sleeping on my stomach during pregnancy?
As the uterus grows, stomach sleeping becomes uncomfortable and may place pressure on the womb. While safe in early pregnancy, it’s not recommended as the belly expands.
3. How can I sleep comfortably during pregnancy?
Support is key. Use pillows to cushion key areas like the back, belly, and knees. Also, opt for a mattress with advanced contouring and temperature regulation to relieve pressure and promote deeper rest.
4. How does the sleeping position affect my baby during pregnancy?
Poor sleeping positions can reduce blood flow to the placenta, potentially affecting nutrient delivery. Side sleeping—especially on the left—optimises oxygen supply and helps maintain stable circulation.
5. Can sleeping on my right side harm my baby during pregnancy?
Not significantly, but left-sided sleeping is still preferred. The right side may slightly compress the liver and limit blood flow. However, alternating sides is perfectly normal and not a cause for concern.
