Ergonomics and joint health
Compute smarter. Avoid neck pain by placing document holders and computer monitors and positioned at eye-level, along with hands-free telephone headsets, can reduce neck strain. -Compute comfortably. Your upper body should be spaced 20 to 26 inches from your computer monitor, the top of which should be at an even line with the top of your head when your head is in neutral position. Your arms should hang comfortably at your sides, elbows at a right angle, with your wrists relaxed while typing. Get a wrist rest for your computer or make your own with two strips of bubble-wrap packing material taped together. Make the bottom strip wider than the top one, and tape the excess width to the bottom of your keyboard so the wrist rest extends outward.
Forget the high heels. Unless you're a fashion model, chances are you can live without high heels. Experts say a tall heel stresses your foot seven times more than a low heel. In addition, heels put extra stress on your knees and may increase your risk of developing osteoarthritis.
Neither sit or stand. Sitting nor standing on your feet all day is not conducive to good joint health. When possible, alternate between the two to prevent locking yourself in one position. If your job primarily involves sitting, take a break and stand up every half hour or so.
