This recommendation displays a rising understanding that sitting is definitely dangerous for our well being – in truth, in 2014, Dr James Levine, a professor of drugs on the Mayo Clinic within the US, coined the phrase ‘sitting is the brand new smoking’ to replicate the rising proof linking inactivity to in poor health well being.
Some research present that individuals who sit for six to eight hours a day have a 20 % larger threat of untimely dying from any trigger.
However why does sitting trigger well being issues? It's thought that sitting for lengthy durations places your physique right into a 'standby' state – your metabolism slows down, blood circulation is impaired as a consequence of bent joints and your capability to course of sugar within the blood is lowered (inactive muscle groups don't take up as a lot blood sugar as energetic muscle groups do).

This will increase the chance of cardiovascular issues, weight problems and kind 2 diabetes.
Mechanical issues may come up from sitting in a single place for lengthy durations of time, resulting in stiffness and ache within the again, neck, and shoulder muscle groups.

Sitting posture may have an effect on your temper — a examine printed in 2017 within the Journal of Conduct Remedy and Experimental Psychiatry discovered that good posture improved the temper of individuals with delicate to reasonable despair.
However London-based physiotherapist Sammy Margo says maybe the 'largest mistake' you may make is staying in a single place for too lengthy. She recommends setting an alarm in your cellphone each half-hour to immediate you to stand up and transfer.
So in the event you discover you haven’t any selection however to lie in your butt for lengthy durations of time, what else are you able to do? Listed below are the most recent science-backed guidelines to minimise any harm.
You don’t want to sit up
Opposite to what you might have been informed, the perfect sitting posture is just not to sit up together with your shoulders hunched again. A 2021 examine within the journal Musculoskeletal Science and Follow discovered no proof that sitting up straight prevents or relieves again ache.
On this examine, measurements have been taken of 100 individuals sitting 'usually' after which sitting extra upright, which was beforehand considered optimum. The researchers discovered that the upright place truly artificially straightens the pure curvature of the backbone, doubtlessly inflicting stress on the physique that’s much less prone to be skilled in a extra pure, relaxed sitting place.
This examine confirmed earlier findings from the identical researchers, printed within the Journal of Orthopaedic & Sports activities Bodily Remedy in 2019, which established that the 'right' posture might fluctuate for various individuals.
'There isn’t any one 'protected' strategy to sit on the subject of again ache,' says Dr Kieran O'Sullivan, senior lecturer in physiotherapy on the College of Limerick.
'For those who really feel advantageous, don't fear about your sitting posture, and when you’ve got ache, see if altering posture eases the ache – simply don't assume the answer is to all the time sit up,' he says.
Due to this fact, just a little little bit of slight bending is appropriate, so long as it doesn’t trigger ache or discomfort.
maintain your ft off the sofa
On the finish of a protracted day you may need to lie down on the sofa together with your legs bent or stretched out, however Sammy Margo warns that these positions put stress on the decrease again – particularly as a result of it's so tempting to sit down on this place for hours.
She says 'it's not good to maintain the again bent in a C-shape for lengthy durations of time' – sitting comfortably is one factor, however sitting hunched over for too lengthy places stress on the discs that assist the vertebrae within the backbone, and the neck and shoulders need to work to stop the top from tilting ahead.
Sammy Margo says that over time, slouching on the sofa can weaken again and stomach muscle groups, which might result in ache. As an alternative, physiotherapists advocate sitting dealing with the TV and conserving your ft flat on the ground.
'In case your couch is deep, put a cushion below your decrease again that will help you keep upright and preserve the pure curve of your backbone – and if you wish to put your ft up, use a footstool that's decrease than the peak of the couch,' says Sammy Margo.
Cross your ankles – not your knees
Analysis reveals that sitting together with your legs crossed causes the pelvis to rotate, and common sitting on this place can result in decrease again ache because it strains the gluteal muscle groups.
A examine printed within the Worldwide Journal of Environmental Analysis and Public Well being in 2020 discovered that sitting together with your legs crossed additionally causes the torso to slouch extra.
A 2018 examine within the journal Utilized Physiology, Diet and Metabolism discovered that sitting together with your legs crossed lowered the pace of blood circulate within the blood vessels of the legs, which can improve the chance of blood clots.
Crossing your legs may mess up the alignment of the backbone and shoulders and finally result in again ache. For those who habitually cross your legs, Sammy Margo suggests switching up the leg you cross steadily ('It's an effective way so as to add motion to your sitting time') or crossing the ankles as an alternative – which doesn't have as a lot of a unfavorable influence on the backbone or blood circulate.
Select 'Carver chair'
If you end up working on the kitchen or eating room desk, Sammy Margo suggests utilizing a 'carver's chair' that has armrests so you possibly can relaxation your elbows at 90 levels to your physique. 'Most eating chairs don't have arm rests, which implies we find yourself elevating our shoulders and resting our arms on the desk, which places stress on the shoulder and again muscle groups,' she says.
In case your solely choice is a eating chair, use a cushion to lift your seating place to the purpose the place your arms may be on the proper angle when resting on the desk — and, if essential, place a thick e book below your ft to assist distribute your physique weight evenly.
Decrease your display (in the event you can't contact sort)
One of many long-established guidelines of desk ergonomics is to maintain your laptop display at eye stage to reduce neck pressure.
Nevertheless, Sammy Margo says this solely applies to expert touch-typists who can use the keyboard with out taking their eyes off the display. Anybody who makes use of one or two fingers of every hand to sort makes use of what physiotherapists name the 'hunt and peck' technique, which requires frequent eye modifications between checking the keyboard and the display.
“For those who can't contact sort, maintain your display barely beneath eye stage to minimise head motion whereas wanting up and down,” she advises.
Ditch that bouncy Swiss ball
It's lengthy passed by the style to sit down on a large Swiss bouncy ball to work out your core muscle groups and get some (regardless of how small) motion into your day. A 2006 examine by the College of Waterloo in Ontario, Canada, discovered that sitting on these ball 'chairs' elevated discomfort as a result of the muscle groups need to work more durable to maintain the physique steady.
Physiotherapists now advocate utilizing an adjustable chair; knees ought to be bent at 90 levels and beneath your hips, your ft ought to be flat on the ground and your again ought to be totally supported.
Use an ironing board as a standing desk
Another choice is to make use of an adjustable bar stool when working on the kitchen counter. Sammy Margo explains: 'Utilizing a bar stool means your hips are larger than your knees, which helps take the stress off your decrease again.'
'However that is solely helpful in the event you're engaged on a kitchen island unit that has a niche huge sufficient so that you can get your knees below it.'
She says that, relying in your peak, a kitchen worktop may make a super standing desk ('elevate your laptop computer barely onto a thick chopping board if essential'), however an ironing board might be even higher as 'it's a super standing desk as you possibly can set its peak to fit your comfort.'
