How To Work on Your Laptop and Stay Healthy

1. Learn how to maintain a relaxed, neutral posture that reduces stress and strain to your muscles by:

  • Schedule mini-breaks every 20 to 30 minutes to avoid repetition and static postures.

  • Maintain a comfortable viewing distance from your notebook screen - about 18-30".

  • Keep your head and neck in a relaxed posture; avoid excessive neck flexion or rotation.

  • Position the keyboard at elbow height and keep your wrists straight while keying.

  • Experiment with table and chair height as well as keyboard angle to maintain neutral wrist postures.

  • If you have to raise your chair, use a footrest to support your feet. When seated, your hips should be slightly higher than your knees.

  • Add an external keyboard and place it on an adjustable keyboard/mouse platform.

  • Attach an external mouse instead of using the small constricted touchpad or trackball.

  • Tilt the screen so that it is perpendicular to your line of sight, if lighting permits.

  • If you are sitting in a side chair or couch, use a pillow to support your arms while keying.

  • Clean the screen regularly using appropriate antistatic cleaning fluid.

  • Your hands and wrists should be kept in a straight wrist posture when typing and should not be resting on a palm rest, table or lap while typing.

  • Did you know: wrist and palm rests are designed to provide support during breaks from typing.

2. Carry your laptop computer ergonomically:

  • Remove unneeded baggage from your notebook case, the less weight to carry the better.

  • Carry your laptop in a case with padded should straps and handle. Frequently shift shoulders to balance the load.

  • Do yourself a favor by buying a wheeled laptop luggage cart that easily transports your laptop and accessories like laptop printer, laptop cables, paper and other utensils.
