Why Does My Back Hurt When I Sleep While Pregnant?

Back pain during pregnancy can make a restful night feel like a distant memory. I’ve seen many new moms reflect on their pregnancies and talk about the discomfort they experienced when trying to sleep, and back pain is often at the top of the list.

As a neonatal nurse, I’ve heard countless stories, and I know how challenging it can be to find relief. Whether you're in your second trimester or nearing your due date, understanding the causes and solutions for pregnancy-related back pain can make a world of difference.

Back pain while sleeping during pregnancy is usually caused by the growing baby, which puts strain on your spine, poor posture, and your body’s shifting centre of gravity. Sleeping on your side with a supportive pregnancy pillow helps keep your spine aligned and reduces back pain.

Why Does Back Pain Occur While Sleeping During Pregnancy?

Weight of the Baby

As your baby grows, the extra weight adds pressure to your spine and muscles. This strain becomes especially noticeable when you're lying down, as gravity pulls your belly forward, placing added stress on your lower back. As a result, many pregnant women wake up feeling stiff and sore.

Changes in Posture

Your body naturally adjusts its posture to accommodate your growing belly, but these changes can sometimes throw off your alignment, especially when lying down. The combination of shifting weight and an altered centre of gravity can lead to poor sleep positions, which may worsen back pain.

Muscle Strain

Throughout pregnancy, your muscles are working overtime to support your body, which can leave them fatigued. Lying down without proper support can further strain these muscles, particularly in the lower back, leading to discomfort during the night.

Stress and Tension

Stress can cause your muscles to tighten, and this tension often settles in the back. If you’re stressed about your pregnancy or other aspects of life, that mental load can manifest physically and make it difficult to sleep comfortably.

Hormonal Changes

During pregnancy, your body produces a hormone called relaxin, which helps loosen the ligaments and joints in your pelvis to prepare for childbirth. While this is necessary for labor, it can also make your joints less stable, leading to back pain, especially when lying down.

How Can I Relieve Back Pain When Sleeping While Pregnant?

Using a Pregnancy Pillow for Support

One of the best ways to ease pregnancy back pain is by using a pregnancy pillow, like our Butterfly Maternity Pillow®. Its wedge shape supports your belly and back, helping to maintain proper spinal alignment throughout the night.

Many women find that this design significantly reduces pressure on the lower back and keeps them from rolling onto their back, which can increase discomfort.

Sleeping in the Right Position

Side sleeping, particularly on your left side, is considered the best position during pregnancy. It promotes healthy blood flow and reduces the strain on your back.

Sleeping on your back can make things worse by pressing your uterus against your spine, leading to increased back pain. If you're struggling to stay on your side, a pregnancy pillow can help by keeping you comfortable and preventing you from rolling over during the night.

Incorporating Light Stretches Before Bed

Gentle stretching before bed can do wonders for relieving back pain. Pelvic tilts and cat-cow stretches are great options to release tension in your lower back and hips.

These movements help your muscles relax and prepare your body for rest, making it easier to get comfortable once you're in bed.

Maintaining Proper Posture During the Day

What you do during the day impacts how you feel at night. Poor posture during daily activities can contribute to back pain when you're lying down. Make sure you're mindful of your posture, especially when sitting or standing for extended periods.

Keeping your spine aligned during the day will make sleeping at night a little more bearable.

Choosing a Supportive Mattress

Your mattress plays a huge role in managing pregnancy back pain. If your mattress is too soft, you may sink into it, which can lead to awkward sleep positions and worsen your discomfort. Opt for a firm but comfortable mattress that provides good support for your body and helps distribute your weight evenly while you sleep.

When Should I Be Concerned About Back Pain During Pregnancy?

Back pain is common during pregnancy, but if it becomes severe or persistent, it could be a sign of something more serious like sciatica or pelvic girdle pain.

If your pain is intense enough to interfere with your daily activities, it's best to consult your healthcare provider to rule out any underlying conditions and ensure you and your baby are safe.
