Laptops, tablets, phones and portable devices

Hands holding a smartphone over a laptop keyboard

Portable devices are convenient but can encourage awkward posture. Laptops, tablets and phones tend to bring the screen, keyboard and hands close together, which can cause a bent neck, raised shoulders, cramped wrists and eye strain.

Top Tips for Laptop use to reduce strain

This laptop ergonomics video shows why using a laptop on your lap is not suitable for sustained work: looking down stresses the neck, upper back and shoulders. Short, occasional use may be acceptable, but prolonged laptop work requires a different setup.

The main recommendation is to raise the laptop so the top of the screen is near eye level, using a stand, box or books if necessary. If the screen is elevated, use a separate keyboard and mouse so wrists, arms and shoulders are not strained by reaching up to the built-in keyboard.

For regular work, use an external monitor with a separate keyboard and mouse, plus an adjustable chair so the monitor, keyboard and seating can be positioned comfortably.

Safer portable-device habits

  • Laptops: avoid long sessions with the laptop on your lap or on a low surface.
  • Tablets: support the device where possible rather than holding it in one hand for long periods.
  • Phones: avoid prolonged head-down posture when checking work messages or appointment information.
  • Handheld scanners: keep wrists neutral and avoid repeated forceful gripping if the task can be reorganised.
  • Domiciliary admin: plan where you will enter information so you do not have to balance devices awkwardly after visits.
  • E-learning: use a proper setup for longer modules rather than a cramped position during breaks.

Work done on portable devices should be arranged so the task can be completed safely. If a task will take more than a short time, move to a better workstation when possible.

Scenario

A staff member completes mandatory e-learning on a laptop balanced on their lap in the staff room. They look down for an hour, use the trackpad continuously and finish with neck and wrist discomfort.

What would be a better approach?

 

Portable devices are convenient, but longer tasks need a setup that protects your neck, shoulders, wrists and eyes.
