Standing desks and "good posture": what helps your back?

There is no single perfect sitting posture, and a standing desk will not fix back pain on its own. What the research says actually helps at your desk.

"Sit up straight." "Don't slouch." "You need a standing desk — sitting is the new smoking." If you work at a desk, you have heard all of these, probably from several directions at once. And if your back or neck aches by mid-afternoon, it is easy to believe that your posture is to blame and that the right chair or desk would fix it.

The research tells a more useful — and more reassuring — story. This article goes through what we actually know about sitting posture, what standing desks can and cannot do, and the simple habits that make the biggest difference for desk workers, from a physiotherapist's point of view.

The "sit up straight" myth

Most of us were taught that there is a correct way to sit: upright, shoulders back, a gentle curve in the low back, both feet flat. It feels intuitive, and it is repeated by employers, ergonomic checklists and even some health professionals.

But when researchers have looked for evidence that slouching causes back pain, they have struggled to find it. A large review of systematic reviews published in the Journal of Biomechanics found no consensus that any particular spine posture causes low back pain. People with "perfect" posture get back pain; people who slouch all day often do not.

In 2019, a group of physiotherapy researchers wrote an editorial in the Journal of Orthopaedic & Sports Physical Therapy with a pointed title:

“‘Sit Up Straight’: Time to Re-evaluate.”

— Slater and colleagues, Journal of Orthopaedic & Sports Physical Therapy, 2019

Their point was not that posture never matters. It is that there is no single "right" posture for everyone, that comfortable postures vary from person to person, and that fear of "bad posture" can itself make people more guarded, tense and worried about their backs. The same research group found that many physiotherapists still pick upright, curved-spine postures as "best" — a belief that has not kept up with the evidence.

So does posture matter at all?

Yes — but not in the way most people think. What matters is:

• How long you stay in one position. Any posture held for a long time, upright or slumped, becomes uncomfortable. Tissues like change.
• Whether a position aggravates an existing problem. If you already have back or neck pain, some positions will feel worse than others, and it makes sense to adjust them.
• Comfort and variety. The best posture is the one you can change easily.

Physiotherapists often put it this way: your best posture is your next posture.

Standing desks: the hype and the reality

As "sitting is the new smoking" became a headline, standing desks became the obvious fix. Many workplaces bought them, and many people stood at them for a few weeks before going back to sitting.

What standing desks do well

A Cochrane review of workplace interventions found that sit-stand desks reduce the time people spend sitting at work — in the short term by roughly an hour to two hours a day — although the quality of the evidence was low and longer-term effects were less clear. That is genuinely useful: being able to change position easily is the whole point.

What standing desks do not do

• They do not guarantee less back pain. Standing is not automatically better for your back than sitting.
• Standing still for long periods has its own problems. A systematic review in the British Journal of Sports Medicine found that workers who stand a lot at work have more low back and leg symptoms. In an Australian lab study, two hours of standing office work led to more discomfort across the body and a decline in some measures of attention.
• They do not replace exercise. Standing burns only a little more energy than sitting.

In other words, swapping eight hours of sitting for eight hours of standing just swaps one static posture for another.

Is sitting really "the new smoking"?

Long periods of sitting are associated with poorer health. But the picture changes when you account for how active people are. A huge combined analysis of data from more than a million adults, published in The Lancet, found that high levels of physical activity — around 60 to 75 minutes of moderate activity a day — appeared to eliminate the increased risk of death linked to high sitting time.

The practical message: sitting is not poison. Long, uninterrupted sitting combined with little activity is the problem. Moving more — across the whole day and in your leisure time — matters more than the furniture.

What actually helps desk workers

1. Break up long periods of sitting

• Aim to change position at least every 30 minutes.
• Stand up for phone calls, walk to a colleague instead of emailing, refill your water bottle often.
• Set a gentle reminder on your phone or computer if you lose track of time.

2. If you have a sit-stand desk, use it to alternate

• Start with short periods of standing (for example 15–30 minutes in each hour) and build up.
• Shift your weight, use a footrest, or step one foot forward while standing.
• Sit when you need to concentrate on detailed work if standing makes you fidget.

3. Set up your workstation for comfort, not perfection

• Screen roughly at eye level and an arm's length away, so you are not craning forward. If you use a laptop all day, a separate keyboard and a stand help a lot.
• Keyboard and mouse close to you, so your elbows rest near your sides.
• Chair high enough that your hips are level with or slightly above your knees; feet supported.
• Back support that feels comfortable — a lumbar cushion helps some people and not others.

4. Build movement into your day

• A walk at lunch, the stairs instead of the lift, parking further away.
• Two or three short "movement snacks" each day: a few squats, shoulder rolls, a gentle back extension, a calf stretch.
• Regular exercise outside work — walking, swimming, gym, sport — for the overall health benefit.

5. Look after the rest of your life

Stress, poor sleep and low activity all increase how sensitive your back and neck feel. If your pain is worse in stressful weeks, that is not imagined — and it is part of the picture a physio should look at, not only your chair.

A sample day at a sit-stand desk

If you have a sit-stand desk and are not sure how to use it, here is a simple pattern many of our patients find easy to stick to. Adjust it to your work and your body.

The exact minutes do not matter. What matters is that your body changes position many times across the day, and that you are not standing or sitting still for hours at a stretch. If your feet or lower back ache when standing, try a cushioned mat, supportive shoes, or resting one foot on a low step and swapping sides.

Laptops and home offices

Since more people started working from home, we see a lot of neck and shoulder pain from laptops on dining tables, couches and beds. A laptop forces a trade-off: if the screen is at eye level, the keyboard is too high; if the keyboard is comfortable, the screen is too low. For an hour, that is fine. For a full working day, most people end up with their head craned forward and their shoulders hunched.

• Use a separate keyboard and mouse and raise the laptop on a stand or a stack of books, so the top of the screen is near eye level.
• Pick one regular workspace rather than moving between the couch, bed and kitchen bench.
• Make the most of working from home: it is easier to move — hang out the washing, walk round the block, do a few exercises between calls.
• Watch the hours. Working from home often means longer, less broken-up days. Build in a proper lunch break and a clear finish time.

Five desk stretches and movements

These are not about "correcting" posture. They are about movement and variety. Stop if anything increases your pain sharply.

• Seated back extension: hands on your lower back, gently lean back over them, 5 times.
• Chest opener: clasp your hands behind your back and gently lift, 20 seconds.
• Chin tuck: draw your chin gently back (a "double chin"), hold 3 seconds, 8 times.
• Seated twist: turn gently to look over each shoulder, 5 each way.
• Sit-to-stand: stand up and sit down slowly without using your hands, 10 times.

Myths and facts

• Myth: "Slouching damages your spine." Fact: research has not shown that slouched sitting causes back pain. Holding any position for too long is what tends to hurt.
• Myth: "Standing is always better than sitting." Fact: long periods of standing are linked with back and leg symptoms. Alternating is better than either.
• Myth: "I need an expensive ergonomic chair." Fact: a comfortable chair helps, but habits matter more than price.
• Myth: "My back pain means my posture is wrong." Fact: back pain has many contributors — load, activity, sleep, stress and general health. Posture is rarely the whole story.
• Myth: "Sitting is as bad as smoking." Fact: regular physical activity appears to offset much of the health risk associated with sitting.

When to see a physio

Desk-related aches usually settle with more movement and a few changes to your set-up. It is worth getting assessed if:

• Back or neck pain lasts more than a few weeks, or keeps coming back
• Pain spreads into an arm or leg, or you have pins and needles or numbness
• You get regular headaches that start in your neck
• Pain is stopping you from working, sleeping or exercising
• You want a plan to stay pain-free at work rather than reacting to flare-ups

Seek medical help urgently for back pain with numbness in the groin or saddle area, new problems with bladder or bowel control, or weakness in the legs.
