- Whenever you sit down to type at a computer, it's important to make sure that you're typing with proper posture. Doing so can help avoid aches, pains, and other health complications. When you sit down to type, make sure that the screen is at eye level. You don't want your head to be angled too far up or down when looking at your screen. It's a good idea to keep at least 20 to 30 inches of distance between your eyes and the screen to make sure that you don't strain your eyes.
Your elbows should never be positioned at less than a 90 degree angle to ensure that blood flows properly to your hands and fingers. Your feet should be uncrossed and flat on the floor. You should be leaning slightly towards the computer. That is, your abdomen and your thighs should have slightly less than a 90 degree angle between them. Your wrists should be elevated or just slightly resting on the desk in front of you, but there should never be any weight put on the wrists.
It's always important to stand up and stretch every 30 to 45 minutes, and to take breaks regularly. If you experience any lasting discomfort, you should see your doctor as soon as possible.
