SITTING PRETTY WITH COMPUTERS
Incorrect chair positions are a leading cause of neck injuries and discomfort. The Herman Miller office furniture firm found that half the workers it surveyed didn't know how to adjust the back height of a chair, while one out of five didn't have a clue on changing the height of the seat.
A good chair should have an adjustable lumbar support against the lower back to ensure that your spine maintains the right curvature. The positioning should let your arms hang down comfortably, bend at a 90o angle, and put place your hands on the keyboard. Your shoulders shouldn't shrug or be hunched forward, and you shouldn't need to reach to use the keyboard or mouse. If you do a lot of typing, maintain a 'neutral' position, to keep your wrists from twisting or straining. Keep your fingers curved gently and type without pounding the keys. If you use a laptop, putting it on a desk whenever possible will avoid creating wrist and arm strains. It's also a good idea to stand and stretch at regular intervals.
These suggestions aren't rocket science-but you'll be surprised to see how they increase workplace comfort and productivity.
