Why do I wake up with lower back pain?
Direct answerWaking up with lower back pain is usually linked to a mattress that's too soft or too firm, a sleep position that arches or twists your spine, poor core and hip mobility and strength, and many hours of sitting the day before. The first step is to try sleeping on your side with a pillow between your knees, or on your back with a pillow under your knees.
How it shows up
When you wake up, your lower back is sore and stiff, and it gets better after you move around for a few minutes.
Most likely root causes
- Unsuitable mattressSagging or overly firm mattresses don't keep your spine aligned.
- Sleep positionSleeping on your stomach or with one leg twisted arches your lower back for hours.
- Weak core and hipsUnderworked muscles leave your spine without support.
- Too much sittingHours of sitting reduce hip mobility and add to stiffness at night.
Quick self-check
- Is your mattress old or sagging?
- Do you sleep on your stomach?
- Do you spend most of the day sitting?
- Does the pain ease after walking a bit?
If you answered yes to two or more, start with that cause.
First step today
Tonight, sleep on your side with a pillow between your knees, or on your back with a pillow under your knees.
30-day plan
- Week 1: adjust your sleep position and do a few gentle lower-back movements when you wake up.
- Weeks 2 and 3: add core and hip mobility exercises three times a week, plus breaks during the day.
- Week 4: reconsider your mattress if the pain persists and compare your morning pain with where you started.
When to seek professional help
See a doctor if the pain spreads down your legs or comes with tingling, weakness, fever, weight loss, changes in bladder or bowel function, or keeps getting worse.
Frequently asked questions
- Is a firm mattress better for your back?
- Not necessarily. Ideally, a mattress keeps your spine aligned and feels comfortable; one that's too firm can also cause discomfort.
- Should I rest when it hurts?
- In general, staying lightly active helps more than prolonged rest, within the limits of your pain.
