Ergonomics and computer use

Happy New Year! 

I hope everyone has a healthy and prosperous year ahead.

We are going to discuss Ergonomics in this lesson. If you are spending long periods at your computer you need to be aware of how you are sitting and the proper placement of your hands and feet. You may not think it is important but once you start practicing proper posture you notice a difference in how long you can stay at the computer as well as how much better you will feel when you are through.

The proper type of seating arrangement is required when using a computer in order to prevent damage to the body. When using a computer, the user’s head should be centered over the shoulders, shoulders should be relaxed, and the user should be looking straight ahead; not twisted or sitting side-ways.

The monitor should be positioned so that information is at eye level. The user’s head should not be lifted or tilted down. The arms should be level so that the wrists are relaxed, but not laying on the desk. The keyboard should be flat or at a slightly raised angle.

An adjustable chair should be used so that it can be adjusted based on the user’s stature. The chair should have a backrest and adjustable armrests if possible.

The user should take regular breaks to move arms and legs. Stretching fingers, hands, and legs will help to relieve stress and tension.
