It seems that laptop computers are everywhere. In fact, in 2008 global sales of laptops surpassed that of desktop sales. However, the growing popularity of laptops has led to neck and shoulder problems. Laptop computers are designed with portability in mind rather than sound ergonomic principals. Bad posture is inevitable because of the way laptops are designed. The single most harmful position is the laptop hunch. Working on a laptop while its sitting on a desk or table forces you to lean forward, putting strain on your spine and lower back. Spending too much time in this position can cause a great deal of discomfort in your neck shoulders, back and wrist. Below are helpful tips for laptop use:

Use a large screen. Use a laptop with the largest screen possible for your needs to avoid the stressful posture that results from straining to see the text on a small screen.

Place the screen at eye level. Set your laptop height and screen angle so you can easily view the screen without bending or rotating your neck, and put it about an arms length in front of you.

Dont slouch. Despite the name laptop, you want to avoid propping your laptop on top of your lap.

Use a separate keyboard. When using a laptop for extended periods, use an external full-sized keyboard and position it at a height that allows your shoulders and arms to be in a relaxed position.

Use a separate mouse. Use an independent mouse rather than the mouse thats incorporated into your laptop keyboard.

Recline slightly. If you cant use a separate keyboard, an alternative is to find a chair that allows you to recline slightly. This will allow you to position the laptop keyboard and mouse with the least strain on your neck.

Take a break. Take brief breaks every half hour to relieve upper body tension.

Travel light. If you need to carry your laptop, carry your bag across your lower back in a messenger bag, or use a backpack with dual padded shoulder straps.
