1/ Exercise your eyes by looking away from your PC, and focussing on distant objects. Dont look at any one object too long, a few seconds will do.
3/ Exercise your neck by turning your head gently to the left then to the right a few times. Don't strain.
5/ Exercise your elbows. Move your arms to the front, rest the tips of your fingers on your shoulders, and rotate your elbows in small circles 10 times clockwise. Relax, then do the same, rotating your elbows in an anticlockwise direction.
7/ Exercise your shoulders. With head and neck relaxed, squeeze your shoulders upwards towards your ears. Relax. Now reach downward at both sides for a few seconds, not bending and keeping your arms straight. Relax.
9/ Exercise your legs by walking away from your PC at least once an hour. Try taking mini-breaks at your keyboard every 5 minutes or so.
Bonus tip: if you feel embarrassed, start with eye, hand, wrist and neck exercises. But remember that breaks are important too!Gently and gradually exercise your PC stress away, and you'll achieve better productivity, plus healthy more relaxed computing thru 2006 and beyond!
