AVOID!
Safety and Comfort
RIGHT!
Experiment with positioning pillows under your forearms; they may help keep your shoulders relaxed and your wrists straight.
Even on a sofa
Remember to properly support your lower back.
•Avoid slouching.
•Be sure not to recline too much; this may fatigue your neck and upper back.
•Don't bend or angle your wrists.
•Avoid sitting completely still and working without breaks for long periods.
Taking Breaks and Varying Your Tasks
As noted earlier in this Section, your furniture placement, office equipment, and lighting are only a few of the factors that determine comfort. Your work habits are also very important. Remember the following:
Take Breaks
When you work at your computer for long periods, take short breaks at least once per hour and preferably more often. You may find that frequent, short breaks will benefit you more than fewer, longer breaks.
If you find that you forget to take breaks, use a timer or specialized software. Several software tools are available that remind you to take breaks at intervals you specify.
During your breaks, stand up and stretch, especially any muscles and joints you may have held in an extended static posture while using the computer.
