Is Sitting Bad for Your Back? | Osteopath Tunbridge Wells

Part 3 of our Move Better, Feel Better: Pain & Movement Explained series

Written by Jessica Brown, Osteopath and Owner of One Health Osteopathy Clinic, Tunbridge Wells

If you spend much of your working day at a desk, you may be familiar with the feeling of standing up at the end of the day with a stiff lower back, tight hips or an ache across your shoulders.

It is easy to conclude that sitting must be damaging your spine. We are also constantly told to “sit up straight”, improve our posture, buy a better chair or stop slouching if we want to avoid back pain. The reality is more nuanced.

Sitting is not inherently bad for your back, and there is no single perfect posture that protects everyone from pain.

However, spending long periods relatively still can certainly aggravate symptoms in some people, particularly when combined with reduced movement, an uncomfortable workstation, stress, fatigue, poor sleep or simply doing much less physical activity than your body is used to.

At One Health Osteopathy Clinic in Tunbridge Wells, we regularly see people with lower back, neck and shoulder pain that becomes noticeable during desk work, driving or prolonged sitting. Understanding why this happens is much more useful than simply blaming your posture.

Sitting and back pain at a glance

Sitting does not automatically damage your back. Evidence does not support the idea that simply having a desk job inevitably causes lower back pain.

How you sit may matter less than how long you stay still. Recent research in office workers suggests that prolonged and static sitting, fewer movement breaks and sitting behaviour may be more relevant than one particular posture.

There is no perfect posture. Even an apparently excellent sitting position can become uncomfortable if you stay in it for hours.

Changing position is important. Your body is designed to move and generally tolerates variety better than remaining in one position all day.

A good desk setup can help. Ergonomics can make working more comfortable, but an expensive chair or standing desk is rarely the whole solution.

Strength and physical capacity matter too. How much you move outside work, your strength, general fitness, sleep, stress and previous history of back pain may all influence how you feel at your desk.

The aim is not to become anxious about sitting. It is to make sitting one of many positions your body is comfortable using.

Does sitting actually cause lower back pain?

Not necessarily.

The relationship between sitting and lower back pain is complex. People who experience back pain often notice that long periods of sitting make their symptoms worse, but this does not mean that sitting itself has damaged their spine.

Recent research looking specifically at office workers found a mixed relationship between total sitting time and lower back pain. However, a clearer association was found with more static sitting, fewer breaks and certain patterns of sitting behaviour.

In other words, the problem may be less about sitting itself and more about spending too long doing the same thing without enough variation.

This makes sense when we consider how the body works. Muscles, joints, ligaments, discs, fascia, nerves and other tissues continually respond to the loads placed upon them.

Remaining in one position for a prolonged period creates a relatively sustained load through certain tissues while other muscles are doing very little. For many people this is completely comfortable. For someone whose back is already sensitive, fatigued or recovering from an episode of pain, it may be enough to aggravate symptoms.

Why does my back hurt when I sit for too long?

There is rarely one explanation. Several factors may contribute.

Staying in one position for too long

Your body generally likes movement and variation. When you sit for a prolonged period, the joints, muscles and soft tissues around your lower back and hips remain in relatively similar positions. Over time you may start to feel stiff or uncomfortable. Changing position alters the load going through those tissues, which is why simply standing up and walking around can sometimes make you feel noticeably better.

Reduced muscle activity

Sitting requires less activity from many of the large muscles involved in standing and moving. That is not harmful in itself. We all need to sit and rest. Problems can arise when sitting occupies a very large proportion of the day and is combined with relatively little movement or exercise outside work. Over time, maintaining strength and physical capacity becomes increasingly important if you want your body to tolerate the demands of work, exercise and everyday life.

An already sensitive back

If you have recently experienced lower back pain, sciatica or another musculoskeletal problem, sitting may temporarily become more uncomfortable. Certain spinal, muscular or nerve-related presentations may be more sensitive to sustained sitting than others. This is why two people using exactly the same chair can have completely different experiences.

Stress and concentration

When we are busy, stressed or concentrating intensely, we can easily spend several hours barely moving. Stress can also influence muscle tension, sleep and how sensitively the nervous system responds to discomfort. You may notice that your back feels significantly worse after an exceptionally stressful week at work, even though your desk has not changed.

This does not mean the pain is “just stress”. It means that physical and non-physical factors often interact.

Sleep and recovery

Poor sleep can affect pain sensitivity and physical recovery. If you combine long working hours, inadequate sleep, reduced exercise and stress, your tolerance for sitting or other activities may be lower than usual. This is why treating desk-related back pain should involve more than simply examining someone’s chair.

Is bad posture really causing your back pain?

Posture has been blamed for back pain for decades. Many people arrive in clinic saying:

“I know my posture is terrible.”

Often they have become very conscious of how they sit and spend the day repeatedly correcting themselves. The evidence does not support the idea that there is one universally correct posture that everybody should maintain to prevent back pain.

Human bodies are remarkably varied. Some people naturally sit upright. Others prefer to lean back, cross their legs, tuck one leg underneath them or move regularly between several positions. Rather than trying to maintain one rigid “ideal” posture all day, it is often more useful to think about comfortable variation.

A helpful posture is one that works for the task you are doing and that you can comfortably change when you need to. The problem with even the “best” posture is that if you hold it rigidly for eight hours, it may eventually become uncomfortable.

Your next posture is often your best posture.

So should I stop slouching?

Not necessarily. Slouching for short periods is not inherently dangerous. Your spine is designed to bend.

There may be occasions when a more supported or upright sitting position is more comfortable, particularly if your back is currently sensitive, but that does not mean flexing your spine or relaxing into a chair is damaging it.

What tends to be more useful is having several comfortable options. You might work upright for a while, lean back into your chair later, stand for a phone call, walk while listening to a meeting and change position again afterwards.

The goal is variety rather than perfection.

What is a good desk setup for back pain?

Although there is no perfect workstation, your desk should allow you to work without unnecessary effort or strain.

As a general starting point:

your feet should be comfortably supported on the floor or a footrest;
your chair should provide enough support for you to feel comfortable;
your keyboard and mouse should be within easy reach;
your shoulders should be able to remain relatively relaxed;
your screen should be positioned so that you can view it comfortably without repeatedly craning your neck, or twisting to one side;
your desk and chair height should suit your body rather than forcing you into an awkward position.

Laptop working deserves particular attention.

Using a laptop on a sofa or at a kitchen table occasionally is unlikely to be disastrous, but doing this for eight hours every day may become uncomfortable. If you regularly work from a laptop, using a separate keyboard and mouse with the screen raised can give you considerably more freedom in how you position yourself.

Good ergonomics should make working easier and more comfortable. But ergonomics alone cannot compensate for never moving.

How often should you get up from your desk?

There is no magic interval that suits everybody. You do not need an alarm forcing you to stand every twenty minutes if you are comfortable and concentrating well. Equally, regularly working for three or four hours without moving is unlikely to give your body much opportunity for variation.

A practical approach is to change position before you become very uncomfortable. For many people that might mean moving or standing every 30 to 60 minutes. If your back is currently sensitive, you may prefer shorter intervals.

The break does not need to be complicated.

You might:

stand while making a phone call;
walk to get some water;
take a brief walk between meetings;
walk around while thinking through a problem;
change from sitting to standing;
perform a few comfortable movements;
take the stairs rather than the lift;
walk at lunchtime.

Even brief periods of movement can break up long stretches of static sitting.

Research into workplace breaks suggests that active breaks involving a change of posture may help reduce discomfort, without necessarily reducing work productivity.

Is a standing desk better for your back?

A standing desk can be useful, but it is not a cure for back pain. Replacing eight hours of sitting with eight hours of standing simply swaps one prolonged position for another. The real advantage of a height-adjustable desk is that it makes it easier to alternate between sitting and standing.

Recent research suggests that sit-stand desks can substantially reduce sitting time, and some studies have found improvements in lower back discomfort among office workers. If you introduce a standing desk, build up gradually. Standing for hours on the first day may simply make your feet, legs or back tired. Think of it as another position available to you rather than the position you should now use all day.

There is no single exercise that everybody who sits at a desk needs to perform. Your body does not necessarily need to be “corrected” because you work at a computer.

The bigger question is whether your normal week contains enough movement and physical challenge to balance the amount of time you spend relatively inactive.

Useful exercise might include:

walking;
strength training;
mobility exercises;
Pilates;
yoga;
swimming;
running;
cycling;
gym-based exercise;
sport;
or simply being more physically active throughout your day.

If you already have back pain, the best exercises will depend on your symptoms and what you need to return to doing. Someone with an acute and irritable episode may initially need gentle movement and activity modification. Someone with recurring desk-related back pain may benefit more from progressively improving strength and physical capacity.

There is rarely one special exercise that everybody needs. Consistency usually matters more.

Does stretching help back pain from sitting?

Stretching can be particularly helpful after sitting for long periods, especially if your hips, back or shoulders feel stiff or restricted. It can help restore comfortable movement, reduce a sense of tension and provide a useful change of position after being relatively still.

Feeling “tight” does not always mean that a muscle has physically shortened. Sometimes tissues simply feel stiff because they have been held in one position for a prolonged period. Stretching can still be very useful in helping you move more freely and feel more comfortable.

Gentle, regular stretching often works well alongside other forms of movement such as walking, changing position, moving your spine, performing a few squats or simply getting away from your desk for a few minutes.

For recurring problems, the best results often come from combining stretching and mobility work with strengthening, regular movement and general physical activity.

What about neck and shoulder pain?

Lower back pain is not the only musculoskeletal problem that can become noticeable with prolonged desk work. Neck pain, shoulder discomfort, pain around the shoulder blades and headaches can also occur, but the causes are not always related to sitting alone.

Muscles, joints, tendons, nerves and the shoulder itself may all contribute, alongside factors such as movement, strength, workload, sleep and stress.

We explore this in more detail in the next article in the series: Neck and Shoulder Pain: What Could Be Causing It and What Actually Helps?

Can an osteopath help with back pain from sitting?

Osteopaths are regulated healthcare professionals trained to assess and manage musculoskeletal problems, including lower back pain.

If sitting consistently aggravates your back, an assessment can help establish why.

At One Health, we look at more than your sitting posture.

Your assessment may include your:

lower back;
pelvis and hips;
upper back and rib cage;
muscles and fascia;
joints;
strength and movement;
nervous system;
work setup;
exercise and activity levels;
previous episodes of pain;
sleep and general health.

We also want to understand what happens during your working day.

Does your back hurt immediately when you sit, or only after several hours?
Does standing help?
Does walking improve it?
Are symptoms worse after driving?
Does exercise make your back feel better or worse?

The answers help us understand what may be contributing and how best to approach it.

Osteopathy looks at how different parts of the body work together rather than treating one painful area in isolation.

Your lower back functions alongside your pelvis, hips, upper back, ribs and surrounding muscles and fascia.

Movement also supports normal circulation and fluid exchange through tissues, while regular muscular activity helps maintain strength, coordination and physical capacity.

Where appropriate, osteopathic treatment may include:

joint mobilisation and articulation;
soft-tissue techniques;
myofascial techniques;
stretching and mobility work;
muscle energy techniques;
manipulation where clinically appropriate and with your consent;
neuromuscular and movement retraining;
progressive strengthening and rehabilitation;
advice about sitting and workplace ergonomics;
strategies for introducing more movement into your working day.

We do not expect everyone with desk-related back pain to need the same treatment. For one person, improving movement around the hips and back may be useful. For another, the bigger issue may be gradually rebuilding strength after becoming less active. Someone else may need advice about how to manage an irritable back while continuing to work.

The aim is to understand your particular combination of factors and help your body tolerate the demands you place upon it.

Consider seeking an assessment if:

your back pain is regularly affecting your working day;
sitting tolerance is becoming progressively shorter;
the problem keeps returning;
pain is affecting sleep or normal activities;
you have started avoiding exercise because of your back;
pain travels into your buttock or leg;
you experience tingling, numbness or weakness;
you are unsure how much activity is appropriate;
changing your workstation has not solved the problem.

It can also be useful to seek advice if you simply want to understand why your back repeatedly becomes uncomfortable at work and what you can do to manage it more effectively.

When should back pain be checked urgently?

Most desk-related back pain is musculoskeletal and is not an emergency. However, seek urgent medical advice if back pain is severe and rapidly worsening or you feel generally unwell, feverish or shivery.

Seek immediate emergency assessment if you develop symptoms such as:

new numbness around the genitals, anus or saddle area;
new loss of bladder or bowel control;
significant weakness or altered sensation affecting both legs;
severe symptoms following significant trauma;
or other sudden neurological changes.

These symptoms are uncommon, but they should not be ignored.

Frequently asked questions about sitting and back pain

Can sitting for too long cause lower back pain?

Long periods of sitting can aggravate lower back pain in some people, particularly when sitting is very static and there are few opportunities to move. However, sitting itself is not automatically harmful and is unlikely to be the only factor involved.

What is the best sitting position for lower back pain?

There is no single position that is best for everybody. A supported and comfortable position can be useful when your back is sensitive, but changing position regularly is often more important than trying to maintain one ideal posture all day.

Is slouching bad for your back?

Occasionally sitting in a slouched position is not inherently dangerous. Problems are more likely to arise when any position becomes uncomfortable and you remain in it for a prolonged period. Your spine is designed to move through different positions.

How long should I sit before standing up?

There is no universally correct interval. As a practical starting point, many people find changing position every 30 to 60 minutes helpful. If your symptoms begin sooner, change position earlier rather than waiting until your back becomes very uncomfortable.

Is standing better than sitting for lower back pain?

Not necessarily. Both sitting and standing can become uncomfortable if maintained for too long. Alternating between them and introducing regular movement is often more useful than trying to stand all day.

Do standing desks help back pain?

They can help some people because they make it easier to alternate between sitting and standing and reduce prolonged sedentary time. They are best viewed as one tool rather than a treatment in themselves.

Should I use lumbar support?

Some people find lumbar support comfortable, particularly during an acute episode or long periods of driving. Others do not need it. There is no requirement for everybody to sit with a lumbar roll or highly supportive chair.

Can weak core muscles cause back pain from sitting?

Back pain is rarely explained by one supposedly weak muscle group. Strength and physical capacity can certainly be relevant, but your trunk muscles are only one part of a much larger system. Rehabilitation may include trunk, hip and whole-body strength depending on your needs.

Is walking helpful after sitting all day?

For many people, yes. Walking provides a simple change of position and activates muscles that have been relatively quiet during the working day. It also contributes to your overall physical activity.

Should I see an osteopath for back pain from sitting?

An osteopath can assess whether joints, muscles, soft tissues, nerves, movement, strength or other factors may be contributing to your symptoms. Where appropriate, treatment may combine hands-on osteopathic care with movement, rehabilitation and practical advice about your working day.

Evidence and further reading

Current evidence suggests that the relationship between sitting and lower back pain is not as simple as sitting being inherently harmful. A 2025 review of 22 studies involving 7,814 office workers found mixed results for total sitting time, with stronger associations seen between lower back pain and sitting behaviour, including prolonged static sitting and fewer changes of position.

The World Health Organization recommends reducing prolonged sedentary behaviour and replacing sedentary time with physical activity where possible. Physical activity, good sleep, mental wellbeing and appropriate workplace adjustments also form part of contemporary approaches to lower back health.

Research into sit-stand workstations suggests that they can reduce sedentary time, and emerging evidence indicates that alternating between sitting and standing may improve lower back discomfort for some office workers.

Clinical evidence continues to evolve, and this article should be reviewed periodically as new research becomes available.
