The evidence behind Posture
Posture exists because sitting still for hours is hard on the body, and short, regular movement is what the guidance and research support. Here is what the evidence says, and what it doesn't.
The rules on screen breaks
- In Great Britain, the Health and Safety (Display Screen Equipment) Regulations 1992 require employers to plan work so that screen use is "periodically interrupted by such breaks or changes of activity" (regulation 4).
- HSE's guidance favours short, frequent breaks, getting up and moving, and breaks the worker controls. It notes that break-monitoring software can remind people to take breaks, while the employer stays responsible (HSE: DSE work routine).
- The EU has the same duty in Directive 90/270/EEC, and Germany in the Workplaces Ordinance (ArbStättV, Annex 6).
What the research shows
- Energy and fatigue: a 2022 meta-analysis of 22 studies found short micro-breaks raise vigour and reduce fatigue, without hurting performance (Albulescu et al., PLOS ONE).
- Strengthening: in office workers who already have neck pain, neck and shoulder strengthening exercises reduce it (meta-analysis). That's why the breaks include strengthening moves, not only stretches.
- Sitting less: prompts to break up sitting are a recognised approach, though the evidence for them is still low quality (Cochrane review).
What it doesn't show
A 2025 Cochrane review found it is very uncertain whether extra work breaks prevent back or neck pain in healthy workers, and found little difference between active and passive breaks for pain (Cochrane, 2025). So Posture doesn't claim to prevent or treat pain or injury. It aims to make regular movement easy, which is good for energy and comfort and helps you follow the guidance on screen breaks.
The size of the problem
- In 2024/25, 511,000 workers in Great Britain had a work-related musculoskeletal disorder, and 7.1 million working days were lost to them (HSE).
- 28% of EU workers sit almost all the time at work (EU-OSHA).
How the exercises are chosen
Each move is a common desk exercise with its own guide page, sources and a list of who should skip it. The health check in Settings leaves out exercises that don't suit particular conditions, and every break says to stop if something hurts. Posture gives general wellness guidance, not medical advice.
