Injuries from laptop computers The growing use of laptop computers has caused more pains, strains and injuries among computer users. But these days many people use a laptop all the time. The problem is that the monitor and keyboard of a laptop are very close together. To position the monitor at the right height for your back and neck causes you to lift your arms and shoulders too high.
But to position the keyboard at the best height for your arms and shoulders, you must hunch your shoulders and neck to see the monitor. Carrying your laptop around can also strain your muscles and joints. Preventing injury from laptop computers Tips to reduce laptop dangers include: Use a correctly set-up desktop computer instead of a laptop as often as you can. Use peripheral equipment, such as a docking station, separate keyboard, mouse and laptop stand. Take frequent breaks.
Carry your laptop in a backpack or in wheel-along luggage.
