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

Standing desks went from novelty to office standard in about a decade, and they're usually sold on health grounds. So what do trials actually show? The short version: standing desks reliably help people sit less. Whether that leads to better health is a separate, and much less settled, question.

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.

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 trial published in the BMJ gave firmer numbers (Edwardson et al., 2022). It followed 756 desk-based local government employees in the UK for twelve months, in three groups: a workplace programme to sit less plus a height-adjustable desk, the programme alone, or no change.

At twelve months, the group with the desk sat about an hour a day less than the control group. The programme without a desk cut about 22 minutes a day.

Both groups also reported small improvements in stress, wellbeing and vigour. The benefits were small and mainly psychological. 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 support around the desk: a programme, goals, prompts. 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 some structure 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.
