Being physically active can put a strain on your lower back, regardless of whether you’re an elite athlete or focusing on your first 5K. If your back is sore from a run, workout, or game, it probably feels great to sink into a cozy bed at the end of the day.
When you have a supportive and comfortable mattress, you’re more likely to get consistent, high-quality sleep. Getting better sleep doesn’t just help your low back—it also supports muscle recovery, energy levels, and overall health. But the wrong mattress might be wreaking havoc on your lower back. In this guide, we’ll break down what commonly causes lower back pain, how to prevent it, and how to choose the best mattress for lower back pain relief.
What Causes Lower Back Pain?
Low back pain can occur suddenly from stress, or it can develop gradually from everyday activities. Exercise, lifestyle habits, and your sleep environment can all cause or contribute to pain in your lower back. In some cases, lower back pain can also be a sign of a more serious injury or chronic health condition; if you’re experiencing severe pain or it does not go away with time and rest, talk to your healthcare provider.
Lifestyle & Movement Causes
The activities you do while you’re awake can cause lower back aches that make you toss and turn at night. Certain movements and lifestyle choices can cause low back pain, including:
- Poor Posture During the Day– Slouching at your desk, craning your neck at a screen, or not standing up straight can put added stress on your lower back. Over time, this strain can cause aches and pains.
- Sitting for Long Periods– Sitting for too long can put tension on the muscles around your spine. This can pull your lower back out of alignment.
- Overtraining or Improper Exercise Form– Athletes may be prone to low back pain or discomfort when training volume increases too quickly, or when using improper form. Pushing yourself through fatigue or lifting too heavy without engaging your core can overload the lower back.
- Injury History or Inflammation– Even injuries from years ago can affect how your body functions now. If you’ve been compensating for a past injury or stiffness, this can shift stress to your lower back, making it more prone to new injury.
Sleep-Related Causes
Your sleep position and mattress may also cause back pain or exacerbate an existing issue. For example:
- An Old, Unsupportive, or Sagging Mattress– If your mattress is old or starting to sag, it can cause uneven areas of support for the spine. When your mattress sags in the middle, the lower part of your spine can be pulled out of alignment by dipping too far into the mattress.
- Wrong Firmness for Your Body and Sleep Position– Sleeping on a mattress that’s too soft or too firm for your body weight and sleeping preference can put strain on the lower back by pulling or pushing your spine out of its neutral alignment.
- Lack of Pressure Relief at the Hips– For side sleepers especially, pressure building up at the hips can tilt the pelvis and pull your lower back out of alignment. Without enough cushioning at the hips, your spine may feel the strain.
Lower Back Pain Prevention Strategies
While the mattress you sleep on matters (more on that later!), preventing low back pain also involves changes to your daily habits and a supportive sleep setup.
Daily Habits
The activities you do during the day can affect how your lower back feels at night. Tips to ease the strain on your back include:
- Improve Posture and Ergonomics– Adjust your chair, desk, and screen so you’re not hunching or straining. A small lumbar cushion or rolled towel can help support the natural curve of your lower back while sitting.
-
Take Standing or Walking Breaks– Take regular stretch breaks or stand and walk around for a few minutes every hour to help keep your muscles loose.
- Stretch Tight Areas– Hip flexors, hamstrings, and the lower back can get tight from sitting or repetitive movement. Gentle stretches can help keep the muscles around your spine loose. Stretching before exercise also helps warm up your body and avoid injury.
Exercise & Recovery Tips
In your workout and recovery routine, try to incorporate the following tips to prevent or decrease back pain:
- Warm Up Before Training– Effectively warming up before physical activity helps to activate the muscles you’ll use during training. Working out without warming up your muscles can make them more prone to strain.
- Strengthen Core and Glutes– A stronger core helps protect the lower back from strain, whether you’re lifting heavy at the gym or just lifting groceries. Doing plank exercises can help strengthen the stabilizing muscles all around your core. Glute exercises also help strengthen the lower body, reducing stress on the lower back.
- Prioritize Recovery and Rest– Training causes micro-tears in the muscle fibers and is a normal part of exercising. But proper recovery helps heal and repair muscles, and it’s during the deepest stages of sleep where your body releases growth hormone to allow this process to happen. Getting quality sleep can help you recover for the next day.
-
Incorporate Mobility Work– Mobility exercises like yoga and stretching help strengthen the muscles around joints and increase the range of motion. Doing these exercises before a workout can help prevent lower back stiffness.
Adjusting Your Sleep Setup
Altering your sleep setup may provide the lower back support you need. Depending on your situation, you may want to:
- Replace Your Mattress– If your mattress is no longer supporting the natural curve of your spine and you’re waking with pain and stiffness, it may be time for a replacement.
- Consider a Mattress Topper– If you’re not in a position to replace your mattress, you can work with what you have by adding a mattress topper for added cushion and support.
- Use Pillows Strategically– If you prefer to sleep on your side, use a pillow between your knees to keep the hips aligned. Back sleepers can try a small pillow under the knees to prevent the lower back from arching.
How to Choose the Best Mattress for Lower Back Pain
Here’s how to choose the best mattress for lower back pain to support healthy spinal alignment and provide enough cushion for pressure points.
Mattress Type
The type of mattress you choose matters for supporting your spine. Here’s what you need to know about today’s most common mattress types.
Hybrid Mattresses: Hybrids combine a coiling system with foam or latex layers on top. Supportive coils offer structure for spinal support, while the foam or latex layers help with cushioning for pressure relief. This combination makes hybrids a popular choice for those with back pain.
Memory Foam Mattresses: Memory foam excels at pressure relief and contouring, allowing pressure points like the low back and hips to sink into comfort layers while still providing enough support for the spine. Look for an option with high-density base foam to prevent spinal misalignment and mattress sagging.
Latex Mattresses: Latex is buoyant, responsive, and supportive, helping maintain alignment while still cushioning the body. This material brings a balanced feel and is a natural alternative to polyfoam.
Key Features to Look For
If you’re searching for a better mattress to support your lower back and improve your sleep, consider the following features:
- Firmness Level– People with lower back pain tend to do well with a medium to medium-firm mattress, which brings a balance of cushioning and support for the lower spine. Proper spinal alignment means your spine stays in its natural position, without the spine dipping or arching. Side sleepers often need more cushioning at the hips and shoulders, while back sleepers typically benefit from firmer lumbar support.
- Zoned Lumbar Support– Some mattresses have targeted zoned support in the middle third of the mattress, where your lower back rests. These reinforced layers help keep the spine aligned, while still providing enough contouring and cushioning at critical points like your shoulders.
- Pressure Relief at the Hips– Look for comfort layers that cushion pressure points. These layers provide contouring or cradling of the lower back and hips without letting the body sink too far into the mattress and pull your spine out of alignment.
- High-Density Foam and Coils– Dense foam layers and sturdy, individually wrapped coils (for hybrids) help prevent sagging over time, which is important for back support in the long run.
