Breaking the cycle of poor sleep and long-term back pain
Dr Nicola Tik
When back pain has been around for a while, nights can become something you dread. You lie awake, the ache feels louder in the quiet, and the next day you are tired, stiff and more aware of your back than ever. This guide explains how sleep and long-term back pain can feed each other, and how small routines can help you break that cycle.
Sleep and long-term back pain are closely linked. In one study of people with long-term back pain, around half had sleep difficulties at a level that would count as insomnia, compared with very few people without pain.
The link runs both ways. Pain can make it harder to fall asleep and stay asleep. Poor sleep, in turn, can make pain feel stronger the next day. A large Norwegian study that followed people over around ten years found that those with long-term back pain who often had trouble sleeping were less likely to recover than those who slept well.
That might sound discouraging, but it also means sleep is a place where you can make a real difference.
When pain has been around for a while, your nervous system often becomes more sensitive. It is a bit like an alarm that has become easier to set off. This is not a sign of more damage. It is your nervous system staying on high alert.
Poor sleep turns that sensitivity up further. When you are tired, your brain is less able to dampen pain signals, so the same ache can feel stronger. Better sleep helps turn the volume back down.
The approach with the strongest research behind it for sleep problems alongside long-term pain is called cognitive behavioural therapy for insomnia, or CBT-I. It focuses on sleep habits and the thoughts that keep you awake. Studies show it can improve sleep for people living with long-term pain.
You can borrow some of its core ideas:
Giving your body and mind a chance to slow down before bed can make it easier to drift off. You could try dimming the lights, putting screens away and doing something calming for 30 minutes or so before bed.
Some people find gentle movement helps their back feel looser before bed. Slowly rocking your knees from side to side while lying on the floor, or a few minutes of easy walking, can help.
Your mattress and pillows can make it easier to get comfortable. In a trial of people with long-term back pain, those given a medium-firm mattress were twice as likely to report improvements in pain when lying in bed and on getting up as those given a firm one.
Pillows are a simpler change. A pillow between your knees when lying on your side, or under your knees when lying on your back, can ease the strain on your lower back.
What you do during the day affects how you sleep at night. Regular movement helps both your back and your sleep. Breaking up long periods of sitting, and building in walks or gentle activity, can help your back feel less stiff by bedtime. On days when pain is louder, gentler movement still counts.
