What are unsafe or wrong sleeping positions during pregnancy?

Sleeping on your back, right side, stomach, or in a semi-reclining position can be unsafe during pregnancy. These positions may reduce blood flow, press on organs, or cause discomfort.

Can lack of sleep during pregnancy affect the baby?

Yes, poor sleep can increase stress and blood pressure, which may affect your baby’s growth and increase the risk of complications like preterm birth.

Sleeping Positions to Avoid During Pregnancy and Why They Matter

Getting a good night's sleep during pregnancy isn't always easy. Your body is changing every day and things that once felt normal, like how you sleep, might suddenly feel uncomfortable. You may find yourself waking up often or struggling to fall asleep in the first place. And as your belly grows, you start wondering if the way you're lying down could actually be doing more harm than good. That’s where the concern around wrong sleeping positions during pregnancy comes in. Learning what to avoid can help you feel more at ease and get better rest.

Why Sleeping Positions Matter During Pregnancy

As your pregnancy progresses, your body adapts to support your growing baby. Your uterus expands, blood volume increases, and organs shift to make space. These changes can make certain sleeping positions uncomfortable or risky. Sleeping incorrectly might lead to issues like reduced blood flow, breathing difficulties, or increased back pain. Avoiding these positions is important to ensure your comfort and your baby’s well-being. This becomes even more important in the second and third trimesters when your baby’s size makes proper positioning even more critical.

Sleeping on Your Back

Lying flat on your back is one position you should avoid, particularly after the first trimester. As your baby grows, the weight of your uterus can press down on important blood vessels and organs.

Pressure on the vena cava: The vena cava is a major vein that carries blood from your lower body back to your heart. When you lie on your back, the heavy uterus can compress this vein. That pressure may reduce blood flow to your heart and your baby. You might feel dizzy or lightheaded, and your baby may receive fewer nutrients as a result.
Breathing challenges: The weight of your uterus can press on your diaphragm, making it harder to breathe. This is especially true in the later stages of pregnancy when your belly is larger.
Increased back pain: Sleeping on your back can worsen lower back pain, which many pregnant individuals already experience due to the extra weight they’re carrying.
Digestive issues and haemorrhoids: This position can put pressure on your intestines, leading to problems like constipation or haemorrhoids. It may also contribute to acid reflux or heartburn, which are common during pregnancy.
Potential risks to the baby: Back sleeping, especially in the third trimester, may be linked to a higher risk of stillbirth or reduced foetal growth due to decreased circulation to the placenta.

If you wake up on your back, don’t worry. Just gently roll onto your side and try to stay there. Avoiding prolonged back sleeping is the goal.

Sleeping on Your Stomach

If you love sleeping on your stomach, pregnancy might make this habit tough to maintain. It’s generally safe in the early weeks of pregnancy when your belly is still small, but stomach sleeping becomes problematic as your pregnancy advances. This is why you should avoid it:

Pressure on your womb: Lying on your stomach is one of the wrong sleeping positions during pregnancy as it puts direct pressure on your uterus. This can be uncomfortable for you and harmful for your baby, as it may compress the womb and restrict space for your baby to move or grow.
Increased risk of complications: Stomach sleeping in the later stages may increase the risk of serious issues like miscarriage due to the pressure it places on the developing baby.
Physical discomfort: By the second and third trimesters, your growing belly makes stomach sleeping physically impractical. It can feel like trying to balance on a basketball, which isn’t restful at all.

Sleeping on Your Right Side

Sleeping on your right side isn’t as harmful as back or stomach sleeping, but it’s still not ideal in the later stages of pregnancy. It’s okay to switch to your right side occasionally for a break, but you shouldn’t rely on it as your main sleeping position. This is why:

Pressure on the liver: When you sleep on your right side, the weight of your uterus can press on your liver. This may interfere with the liver’s ability to detoxify your body, which is already working hard to support your pregnancy.
Potential health risks: Some research studies linked right-sided sleeping to a higher risk of complications like stillbirth, reduced foetal growth, low birth weight, or preeclampsia (a condition involving high blood pressure).
Less effective circulation: Compared to left-side sleeping, right-side sleeping doesn’t promote optimal blood flow to the placenta.

Semi-Reclining Position

Some pregnant individuals try sleeping in a semi-reclining position, especially if they’re dealing with heartburn. But it might not be the best choice, as it is one of the wrong sleeping positions during pregnancy.

Limited benefits: A semi-reclining position can help ease heartburn by keeping stomach acid from rising into your oesophagus. However, it doesn’t provide the same circulatory benefits as sleeping on your left side.
Potential discomfort: Staying semi-reclined for long periods might strain your back or neck if you don’t have proper support. It’s not a sustainable position for a full night’s sleep.
Not a substitute for side sleeping: Semi-reclining can be a temporary solution for specific discomforts, but it’s not recommended as your primary sleeping position. It may still put some pressure on your blood vessels and organs compared to side sleeping.

Tips to Avoid These Positions

Switching away from your usual sleeping habits can feel challenging if you’ve always slept on your back or stomach. These are some practical ways to avoid the wrong positions during pregnancy and make sleep more comfortable:

Use pillows for support: Place a pillow between your knees to keep your hips aligned and reduce strain on your lower back. A wedge pillow under your side can also prevent you from rolling onto your back during the night.
Adjust your bed: If heartburn is an issue, try raising the head of your bed slightly or using pillows to prop up your upper body. This can help without relying on a semi-reclining position all night.
Practice during the day: Spend some time lying on your left side during the day to get used to the position. This can make it feel more natural at night.
Talk to your partner: If you share a bed, let your partner know about your need to avoid certain positions. They can gently remind you to shift if you roll onto your back or stomach.

The wrong sleeping positions during pregnancy can cause discomfort or even complications. You can rest more comfortably and support a healthier pregnancy by being mindful of these positions and making small adjustments. Sleep well and take care of yourself on this incredible journey to parenthood!
