We spend roughly a third of our lives asleep, yet how we position our bodies during those hours rarely gets the attention it deserves. At Pinnacle Physiotherapy, patients frequently report that their pain is worst first thing in the morning — a clear sign that sleep position and surface may be contributing to their problem.
Why sleep position matters
During sleep, your spine should ideally maintain its natural curves — the slight inward curve of the lower back (lordosis) and the outward curve of the thoracic spine (kyphosis). Positions that distort these curves for hours at a time place sustained stress on joints, discs, and muscles, and can leave you feeling stiffer and more sore than when you went to bed.

The best positions for back and neck pain
On your back (supine)
Sleeping on your back is generally considered the most neutral position for spinal alignment. Place a pillow under your knees to reduce tension in the lower back — this slightly flattens the lumbar curve and takes pressure off the facet joints. A supportive but not overly thick pillow under your head keeps the neck in a neutral position.
On your side
Side sleeping is comfortable for many people and works well with the right modifications. Place a pillow between your knees to prevent the top hip from dropping forward, which can rotate the lower spine and create strain. Keep your head pillow thick enough to fill the gap between your shoulder and your ear, maintaining a straight neck.
On your stomach (prone)
Stomach sleeping is generally the most problematic position for spinal health. It forces the neck into sustained rotation and flattens the lumbar curve, placing considerable load on the facet joints. If you find it difficult to change position, try placing a flat pillow under your pelvis and lower abdomen to reduce the spinal strain somewhat.
Mattress and pillow selection
There is no single "best" mattress for back pain — the right choice depends on your body type, preferred sleep position, and specific condition. Generally, a medium-firm mattress works well for most people with back pain. A mattress that is too soft allows the hips to sink and the spine to sag; one that is too firm creates pressure points at the hips and shoulders.
When morning stiffness won't go away
If you consistently wake with significant stiffness or pain that takes more than 30 minutes to ease, or if your symptoms have been worsening over time, it's worth having a physiotherapy assessment. There may be an underlying mechanical issue that simple position changes won't fully resolve.
