Why posture gets so much blame

Most of us grew up being told to sit up straight. The idea that slouching damages the spine is so familiar that it feels like common sense, and a whole industry of posture correctors, special chairs and apps has grown up around it. Yet when researchers have looked closely, the evidence that posture causes pain is surprisingly weak.^[2]

What the research shows

A large review pulled together 41 systematic reviews on spinal posture, sitting, standing, bending, twisting and heavy physical work in relation to low back pain. Some found links and some did not. The evidence that these factors come before back pain starts, or that more exposure means more pain, was mixed. The authors concluded there is no consensus that posture or physical exposure causes low back pain.^[1]

The picture for the neck is similar. In a long-running Australian study (the Raine Study), researchers photographed the sitting posture of 17-year-olds and asked about neck pain again at age 22. In young men, posture at 17 made no difference. In young women, those who sat in a more slumped or relaxed way were actually less likely to have persistent neck pain five years later than those who sat bolt upright. The authors suggest that generic advice to sit up straight to prevent neck pain needs rethinking.^[3]

None of this means posture is irrelevant to how you feel. Holding any position for a long time can cause aching, and if your back or neck is already sore, some positions will feel better than others. The point is that a slouched posture is not a sign of damage, and you do not need to fear it.

What about tech neck?

Tech neck, or text neck, describes the head bent forward to look at a phone or tablet. It is often blamed for a rise in neck pain. One study asked 150 young adults aged 18 to 21 to text on a phone while their neck posture was judged both by themselves and by physiotherapists. There was no link between the posture they adopted and neck pain, or how often they had it.^[4] This was a single, small study at one point in time, so it cannot settle the question. Still, it fits with the wider research above.

If your neck aches after long spells on a device, the most likely explanation is staying still for too long, not that the posture has harmed your spine. Lifting the phone a little, changing position and taking breaks will usually help. Mr Sadek discusses the forward head posture sometimes called a neck hump in this video.

Common myths

Myth	What the evidence suggests
Slouching damages your spine.	Research has not shown that slouched sitting causes back or neck pain.[1][3]
There is one correct posture.	People sit and stand in many different ways without pain. Comfort and variety matter more.
Looking at your phone will wear out your neck.	A study of young adults found no link between texting posture and neck pain.[4]
A standing desk will cure back pain.	Sit-stand desks cut sitting time, but have not been shown to clearly reduce pain.[5][6]

Do sit-stand desks help?

Sit-stand desks do what they promise in one sense: people sit less. A Cochrane review found that they reduced sitting at work by an average of about 100 minutes a day in the first few months, and by about an hour a day at 3 to 12 months, although the evidence was low quality and there was no information on the longer term.^[5]

Whether that translates into less pain is less clear. A second Cochrane review looked specifically at office workers with musculoskeletal symptoms. Interventions to increase standing or walking at work, including sit-stand desks, did not clearly reduce back, neck or shoulder symptoms. The evidence was low or very low quality and the studies were small, so a benefit has not been ruled out.^[6]

A sit-stand desk is still a reasonable choice if you like the idea and it helps you move more. Standing all day is not the goal. The benefit, if there is one, probably comes from switching between positions.

Setting up your desk

The Health and Safety Executive (HSE) gives straightforward guidance for people who use computers at work or at home.^[7] Treat these as starting points for comfort rather than strict rules:

• Top of the screen roughly level with your eyes, about an arm’s length away.
• Screen and keyboard straight in front of you, so you are not twisting.
• Keyboard just below elbow height, mouse in line with your elbow, shoulders relaxed.
• Seat height that supports the front and back of your thighs, with a small gap behind the knees.
• A chair, or cushion, that supports your lower back.
• For laptops used for long periods, a separate keyboard and mouse with the screen raised on a stand.

The HSE also advises short, frequent breaks rather than occasional long ones, for example 5 to 10 minutes every hour rather than 20 minutes every two hours, with the chance to get up and move around.^[8]

Practical tips

• Your best posture is your next one. Shift position often, and do not worry about how you look while doing it.
• Stand up for phone calls or walk to speak to a colleague rather than sending an email.
• Set a reminder to get up every 30 to 60 minutes if you tend to lose track of time.
• Hold your phone a little higher for long reading sessions, and swap hands or positions.
• Stay generally active. Regular exercise does more for your spine than any chair or gadget.

Hand clumsiness and balance problems can be signs of pressure on the spinal cord in the neck. Saddle numbness and bladder or bowel changes can point to cauda equina syndrome. Both need prompt assessment.
