Are standing desks worth it? What trials say about sitting less at work

A standing desk can be part of a plan to sit less. In a large trial, people who received a desk plus a support program to change their habits sat less than those who continued their usual work habits (Edwardson et al., 2022). The trial did not test a desk alone or show that sitting less guarantees better health.

Do they reduce sitting? Yes

A 2018 Cochrane review looked at 34 studies of workplace interventions for sitting less, with about 3,400 participants (Shrestha et al., 2018). Sit-stand desks cut workplace sitting by around 100 minutes a day in the short term and by about an hour a day at medium-term follow-up. The authors rated the evidence as low quality, largely because the studies were small or had design limitations. Those figures count sitting at work only.

The review also found early, low-quality evidence for other approaches. In one study, breaks of one to two minutes every half hour reduced sitting more than two long breaks a day. In another, computer prompts plus information reduced sitting at medium-term follow-up.

A bigger trial, a year long

A 2022 study followed 756 UK office workers for a year (Edwardson et al., 2022). Researchers assigned 78 workplace groups to one of three options: usual work habits, a support program to sit less, or the same support program plus an adjustable desk. The support program was education, goal setting and reminders, with no new desk.

After 12 months, the group with the support program sat about 22 minutes less per day than the group with usual work habits. The group with the support program plus a desk sat about 64 minutes less (Edwardson et al., 2022). These estimates account for factors such as starting sitting time. They include sitting at work and outside work, and they do not predict each person's result.

Both program groups also reported small improvements in stress, wellbeing and energy (Edwardson et al., 2022). Those were small changes on questionnaires people answered about themselves. That's the gap in the evidence: sitting less is clearly achievable, but these trials haven't shown a longer-term health payoff.

What experts recommend

An expert statement from 2015 recommended that desk workers build up to two hours a day of standing and light activity during working hours, eventually reaching four (Buckley et al., 2015). It named several ways to get there, and a sit-stand desk is only one of them.

The authors were clear that their recommendations rest largely on observational and short-term studies. It's expert opinion informed by evidence, not proof from long-term trials, and it isn't an official health guideline.

What these trials didn't test

It's worth noticing what the trials measured: time spent sitting, plus some questionnaires about how people felt. They didn't test whether standing desks change back pain, heart health or weight over years. And the biggest results came with the support program around the desk: education, goals and reminders. A desk delivered on its own and left in the sitting position is a different thing.

Standing for long stretches also isn't the goal in any of these recommendations. The expert statement talks about standing and light activity, and the trials were about breaking up sitting, not replacing it with hours of standing still.

So, are they worth it?

If your goal is to sit less, a standing desk is one of the best-tested ways to do it, especially with a support program around it. If your goal is a specific health outcome, the trials haven't shown that yet. Either way, how you use the desk matters.

• Use it to change position, not to stand still for hours. Standing still is still one fixed position.
• Alternate. Sit a while, stand a while, and move in between.
• Add movement. Calf raises, weight shifts and a short walk turn standing into activity.
• No standing desk? Short, frequent breaks also cut sitting in the Cochrane review, though that evidence is thin.

DeskBreak's standing reset is designed for the desk-up moments: a few minutes of leg, hip and shoulder movement, with the desk right there for balance. Raise the desk, do the reset, and decide whether to keep standing or sit back down. Either is fine, as long as the choice changes through the day.
