Posture and back health

Low back pain is the world's leading cause of disability, affecting about 619 million people. Surprisingly, there's no single 'perfect posture'. Moving often and staying strong protect your back far more than sitting up straight.

The basics

Your spine is built to move

Your spine has 33 vertebrae with gel-filled discs between them, a gentle S-curve, and layers of muscle that brace and move it. Discs don't have their own blood supply; they take in nutrients as you move and change load.

Large reviews have found no clear link between a particular sitting or standing posture and back pain. What matters more is staying in any position for too long, low fitness, poor sleep, stress and fear of moving. Your best posture is your next posture.

Most back pain isn't caused by serious damage and improves within weeks. Scans often show 'wear and tear' that's normal for your age and unrelated to pain, so imaging is rarely needed unless there are warning signs.

Your best posture is your next posture

Your spine has natural curves and is built to move. Changing position often matters more than holding one 'perfect' pose.

How it works

What keeps a back resilient

1

Change position often

Every 30–45 minutes, stand, stretch or walk for a minute or two.

2

Muscles share load

Strong glutes, back and abdominal muscles spread force away from discs.

3

Discs get fed

Movement pumps nutrients and water in and out of the discs.

4

Back stays resilient

A fitter, more active back recovers faster and hurts less often.

03
Measure it

Check your back health

  • Count sitting hours: add up work, travel and screen time. Many people sit 9–10 hours a day.
  • Back endurance: a side plank or 'Superman' hold of 60+ seconds suggests good trunk endurance.
  • Hip mobility: can you squat to a chair and stand without using your hands?
  • Red flags, see a doctor urgently: numbness around the groin, new bladder or bowel problems, weakness in the legs, fever, unexplained weight loss or pain after a big fall.

Take action

Looking after your back

Movement is the medicine. Comfort beats 'correct' posture.

  1. 1

    Move every 30–45 minutes

    Stand up, walk to get water, or do a few squats or back bends.

  2. 2

    Walk most days

    Build up to 30 minutes, 5 days a week. It prevents back pain coming back.

  3. 3

    Strengthen back, hips and core

    Bridges, bird-dogs, deadlifts and side planks, 2–3 times a week.

  4. 4

    Try Pilates or yoga

    Both had strong results for chronic back pain.

  5. 5

    Stay active when it hurts

    Gentle movement speeds recovery; bed rest slows it.

  6. 6

    Know the red flags

    Numbness, bladder changes or leg weakness need urgent care.

Myth or fact

Common myths, checked

✕ MythBad posture causes back pain.

✓ FactReviews find no consistent link. Being stuck in one position matters more.

✕ MythAlways lift with a straight back.

✓ FactStudies haven't shown that rounded-back lifting causes pain. Strength and gradual loading matter more.

✕ MythRest in bed until it's better.

✓ FactBed rest slows recovery. Keep gently active.

✕ MythA scan will show the cause.

✓ FactMost scan findings are common in pain-free people. Scans are needed only with warning signs.

Questions

Frequently asked

Is a standing desk worth it?

It helps you switch positions. Standing all day isn't better than sitting all day; alternate.

What about 'tech neck'?

Looking down is fine for short spells. Raise your screen and take breaks if your neck aches.

Which mattress is best?

A medium-firm mattress did slightly better in trials, but comfort is personal.
