Rest is best for back pain

What Patients Say

My doctor told me to rest and take it easy. I've been lying in bed for two weeks now and it's actually getting worse — but I must be doing the right thing, right?

Where Did This Come From?

Rest used to be the standard prescription for back pain. Decades ago, doctors genuinely believed this. The logic seemed sound: if moving hurts, don't move. Let the tissue heal in peace. It made intuitive sense — after all, we rest a sprained ankle, we rest after surgery. Why not rest a bad back?

The problem is that a sprained ankle and a painful back are completely different situations biologically. We know that now. But the advice stuck around long after the evidence changed, passed from generation to generation like folk wisdom. Your parents probably got the same advice. Their parents definitely did.

Some of this persists because "stay active" is harder advice to give than "rest." It requires more explanation, more reassurance, more pushback when the patient is scared. It's easier, in a busy clinic, to say "take it easy for a week." I understand why it happens. It's still wrong.

What the Science Actually Says

The evidence against prolonged bed rest for back pain is overwhelming and has been for over 20 years. A landmark Cochrane review — the gold standard of medical evidence — found that bed rest is no better than staying active, and in many cases it's worse. People who stayed active recovered faster, had less disability, and returned to work sooner.

Here's what actually happens when you lie still: your muscles start to weaken after just 24– 48 hours of inactivity. The structures supporting your spine — the deep stabilisers, the core muscles — begin to decondition. The discs, which get their nutrition through movement (they don't have their own blood supply), start to get less of what they need.

And the nervous system starts to amplify pain signals, partly through fear-avoidance: the less you move, the more your brain associates movement with danger, the more pain you feel when you eventually try to move.

Short rest? Fine. If you've had an acute painful episode, 24–48 hours of taking it easy is completely reasonable. But beyond that, you're not resting your way to recovery. You're prolonging it.

The Verdict

Rest beyond 1–2 days doesn't help. For most back pain, it actively makes things worse. Staying active — even just walking — is better medicine.

What To Do Instead

• After 24–48 hours, start gentle movement: walking, gentle stretching, whatever doesn't significantly worsen your pain
• Modify activities rather than stopping them — if lifting is uncomfortable, don't lift heavy things, but don't stop all movement
• Ask your physiotherapist about "active rest" — there's a big difference between protecting an injured area and immobilising your whole body
• If pain is severe enough that you can't function at all, get it assessed — there may be something specific going on that needs treatment, not just reassurance to keep moving
