5 Carpal Tunnel Syndrome
This computer problem deals with the narrow veins in the wrist called the carpal tunnel are injured due to excessive use. Injuries that occur with the computer include use of the keyboard (incorrect posture or key entry) and mouse (grabbing and dragging either too long or too tight).

Correct typing technique and posture, the right equipment setup and good work habits are the important characteristics of preventing carpal tunnel.

8 POSTURE - some basic guidelines!
Let your shoulders relax Let your elbows swing free Keep your wrists straight Don’t slump or slouch in your chair Feet should be flat on the floor Set the keyboard where the arms are level DO NOT rest your wrists on anything DO NOT pound on the keys - use a light touch Use two hands to perform double key operations (Control C) instead of using one hand to press the two key combination

9 MORE TIPS Take a break from your computer every one to two hours - and stretch your neck and shoulders as well as shake your hands for relaxation. Hold the mouse lightly - don’t grip it hard or squeeze it. Keep it close to the keyboard so you don’t have to stretch. Keep your arms and hands warm - cold muscles are at greater risk for injuries. Pay attention to your body - pain is your body yelling that something is wrong.
