Breaks, movement and workload patterns

DSE risk is influenced by work routine as well as equipment. Even with a well-arranged workstation, long uninterrupted screen time, fixed posture, intense visual focus or repeated manual input can cause discomfort.

Breaks and changes of activity

HSE guidance recommends short, frequent breaks or changes of activity rather than occasional longer breaks. It gives 5 to 10 minutes every hour as an example that may be better than 20 minutes every 2 hours, but the right pattern depends on the work. In many optical roles, the most realistic approach is to vary tasks: alternate screen work with customer-facing duties, filing, room checks, moving stock, cleaning, phone calls or other tasks where this is safe and practical.

Workload patterns to watch

• saving all NHS claims, recalls or emails for one long end-of-day block
• completing e-learning in one cramped session
• reviewing imaging screens for long periods without changing posture
• working through breaks because reception or admin is busy
• standing at a screen without foot support or movement
• using a phone or tablet continuously between patient tasks

Movement does not need to be dramatic. Standing, walking, stretching, changing task, refocusing your eyes, relaxing your shoulders and moving your hands can all help when used regularly.

For DSE work, movement is part of the control. Adjust the setup, vary the task and move before discomfort builds.
