Almost everyone works with a computer these days.
I’ll bet you’re sitting in front on one now!!
An awkward posture while keyboarding, poorly positioned equipment, or just sitting in the same position for hours can cause eyestrain, pain and injury to your wrists, hands, arms, back and neck.Occupational Safety and Health Administration surveys show that each year more than 600,000 workers take disability leave as a result of the various repetitive strain injuries that happen in offices. Injuries range from minor strains to more serious, which require operations.

Here's how to take the pain out of computer work (at least some of it!).

* The Mouse - Avoid this trap! The mouse should be located adjacent to and at the same level as the keyboard. Stretching your arm to operate the mouse can lead to muscle strain. Keep your elbow close to your body when manipulating the mouse. Also use a soft touch, don't death grip the mouse. Think of it as alive and hold it lightly rather than gripping or squeezing.

* Screen Star - The height of the VDT should be adjusted so that the top of the screen is level with or slightly below your eye level (sit up straight!). You can set the VDT on a telephone book or adjust your chair. Keep your eyes about 18-26" from screen to avoid eyestrain.

* Sit on it - Adjust your chair seat height so that there is a straight line from your elbows to the keyboard and mouse. Your arms should fall comfortably straight down at your sides with your elbows bent comfortably at 90 degrees, and with your forearms horizontal and your wrists perfectly straight when you use the mouse and keyboard.
It's important to make sure you don't need to bend your wrists to reach the keys. Your wrists should be straight, not angled up, or down or to the side. This is called a neutral position, where the forearms, wrists and hands are in a straight line.
If your wrists are flexed or extended, the nerves, muscles and tendons that support your wrist and hands become tense and strained. A wrist-rest may be helpful in reminding you to keep those wrists straight.
Most chairs are adjustable now, but you may have to be a chair engineer to figure them out. Look for instructions and fiddle with the controls until you find out what they adjust.
Your hips and knees should be bent at a 90-degree angle
