Standing desk – against sitting, not for standing
In the largest measurement study of 83,013 adults, standing had no association with major cardiovascular events. The harm of long stationary time, meaning sitting and standing together, was mainly driven by sitting.
The standing desk is sold on the back and on calories. What is supported is something else, and it is still a good reason for the desk: it clearly reduces sitting time, over months, and well-being follows. This page shows what the largest measurement study on sitting and standing found and what the desk is good for.
In short
In the UK Biobank, 83,013 adults wore a device on the wrist and were followed up for an average of 6.9 years. Above 10 hours of sitting a day, the risk of major cardiovascular events rose by 15 percent for each additional hour; standing had no association with it. The desk itself reliably affects sitting time: in two randomised trials, employees sat a good hour less per day after 12 months, with more energy and less fatigue. The limits: the large study is observational, above about 2 hours of standing a day the risk of venous disorders rose, and standing does little for calories.
What the desk changes
A height-adjustable desk does not change how much you move, but how you spend stationary time: sitting or standing. For a long time the two were seen as opposites, sitting as harm, standing as the remedy. The largest study so far to measure sitting and standing separately by device separates them differently: the harm of long stationary time was mainly driven by sitting, and standing was associated with cardiovascular risk in neither direction.
This defines the role of the desk. It is an interrupter for sitting, not a piece of training equipment. It does not replace walking; the tips on steps in everyday life and on walking after meals fit with that.
What is well supported
Well supported is that the desk reduces sitting time, and does so lastingly. In the English National Health Service, employees with a desk and support programme sat a good 83 minutes less per workday after 12 months, with better work engagement, less occupational fatigue and less daily anxiety. In UK local councils with 756 employees, it was almost 64 minutes less per day with a desk, and a good 22 with the same programme without a desk. Both groups reported small improvements in stress, well-being and vigour.
What the studies show
UK Biobank, International Journal of Epidemiology 2024
83,013 adults, on average 61 years old, wore a device for 7 days; over 6.9 years, 6,829 major cardiovascular events and 2,042 orthostatic circulatory diseases occurred, meaning varicose veins, chronic venous insufficiency, venous ulcers and a drop in blood pressure on standing up. Sitting above 10 hours a day was associated with 15 percent more cardiovascular events and 26 percent more orthostatic disease for each additional hour. Standing had no association with cardiovascular events; above 2 hours a day, however, the risk of orthostatic disease rose by 11 percent for each additional half hour.
SMArT Work, BMJ 2018
Cluster-randomised trial with 146 office workers at a trust of the English National Health Service: height-adjustable desk with support programme versus usual practice. After 12 months, participants sat a good 83 minutes less per workday, and a good 82 minutes less across the whole day. They also did better on job performance, work engagement, occupational fatigue, working while sick, daily anxiety and quality of life; there was no difference in days of absence.
SMART Work & Life, BMJ 2022
756 employees from 78 teams of UK local councils in Leicester, Liverpool and Greater Manchester, three arms. After 12 months, they sat 22.2 minutes less per day with the programme alone and 63.7 minutes less with programme and desk; the desk made the intervention about three times as effective. The desk group also reported less pain in the legs.
Belgian government agency, 2025
Field experiment with 149 employees from eight departments; cameras recorded every 30 minutes who was standing. Initially, 1.82 percent of the snapshots showed people standing. When the desks were already raised in the morning, it was 4.93 percent, with an open explanation 11.25 and with additional coaching 18.80 percent. Coaching alone showed no confirmed effect.
Energy expenditure, meta-analysis 2018
46 studies with 1,184 participants: standing uses on average 0.15 kilocalories per minute more than sitting. At 6 hours a day and 65 kilograms, that is about 54 kilocalories; assuming everything else stays the same, the authors convert this into about 2.5 kilograms of body fat a year.
Walking breaks while standing, Human Movement Science 2019
19 healthy participants stood twice for 2 hours, once continuously and once with 5 minutes of walking every 25 minutes. Standing continuously, 58 percent developed low back pain; with walking breaks, 26 percent.
Where the data stop
The large study is observational. People who stand a lot work differently, are ill differently, earn differently. With only age and sex in the model, standing looked protective; with smoking, alcohol, body weight and education added, the protection dissolved. The direct comparison is missing: nobody has randomly assigned people to walk instead of stand and then counted heart attacks. The randomised desk trials measure sitting time and well-being, not heart attacks.
The walking trial on back pain had only 19 participants. And the 2.5 kilograms of fat a year is a conversion assuming nothing else changes, not a measured weight loss.
How to do it
Use the desk to replace sitting time, not to collect standing time. Above about two hours of standing a day, the risk of venous disorders rose in the UK Biobank, and two hours is already the average there. The best effect lies in alternating and walking in between: in the standing trial, 5 minutes of walking every 25 minutes reduced the share with back pain from 58 to 26 percent.
A simple trick from the Belgian field experiment: raise the desk at the end of the day, so it is already up in the morning. That alone almost tripled the share of people standing, and with explanation and support considerably more.
Safety
The risk lies not in the desk but in long periods of standing at a stretch. In the UK Biobank, above 2 hours of standing a day the risk of varicose veins, venous insufficiency and a drop in blood pressure on standing up rose by 11 percent for each additional half hour. Long standing without breaks can also trigger back pain, in the trial in 58 percent after 2 hours. If you have varicose veins or feel dizzy when standing up, discuss long standing with a doctor.

The data are good, but the result is different from the sales brochure: in the largest study so far with a wrist-worn device (Ahmadi 2024, 83,013 adults, mean follow-up 6.9 years), there was no association between standing and major cardiovascular events across the entire measured range. What did show up was the harm of sitting: above ten hours a day, the risk rose by 15 percent with each additional hour. For standing itself there was a different finding – 2,042 orthostatic events, and above about two hours of standing a day the risk of venous disorders rose. The hype deduction concerns exactly this shift: the desk works by replacing sitting time, not by creating standing time.

Frequently asked questions about the standing desk
Is standing healthier than sitting?
For the heart, not according to the best measurement data. In the UK Biobank with 83,013 adults, standing had no association with major cardiovascular events, while the risk rose by 15 percent for each additional hour above 10 hours of sitting a day. The benefit of the desk lies in replacing sitting time.
How long should I stand at a standing desk?
There is no tested duration. Above about 2 hours of standing a day, the risk of venous disorders rose by 11 percent for each additional half hour in the UK Biobank, and the cohort average was already 2.1 hours. Alternating and walking in between is better than standing for long stretches.
Does standing burn a meaningful number of calories?
Not many. According to a meta-analysis of 46 studies, standing uses 0.15 kilocalories per minute more than sitting, about 54 kilocalories at 6 hours a day and 65 kilograms. That is roughly one small apple.
Does a standing desk help against back pain?
That is not what the studies show. In a trial with 19 participants, standing continuously triggered low back pain in 58 percent, and with 5 minutes of walking every 25 minutes in only 26 percent. In the largest desk trial, the desk group reported less pain in the legs.
Do people actually use the desk in everyday life?
Often less than expected. In a Belgian government agency, fewer than 2 in 100 snapshots initially showed someone standing. When the desks were already up in the morning, it was almost 5 percent, with an open explanation a good 11 and with coaching added almost 19 percent.
