WORK AREA

The work area should be large enough to accommodate you, allow the full range of motions involved in performing required tasks, and provide room for the equipment and materials that make up the workstation.

* Use a headset for lengthy or frequent telephone work.
* Place the items you use most frequently directly in front of you.
* Avoid overcrowding computer work areas.

DESK/WORKSTATION

Standard furniture cannot accommodate everyone’s needs. A taller person may need a one-time adjustment to have his or her work surface raised somewhat; a shorter person may need a footrest or other accessories. Adjustable furniture may be needed in situations where people share or use the same workstation.

* The desktop should be organized so that frequently used objects are close to the user to avoid excessive extended reaching.
* The work surface should have a matte finish to minimize glare or reflections.
* The area underneath the desk should always be clean/uncluttered to accommodate the user’s legs and allow for stretching.

DESK/WORKSTATION

• If a fixed-height desk is used, add a keyboard tray that adjusts vertically to provide added adjustability.
• A footrest should be used if, after adjusting the height of the chair, feet do not rest flat on the floor.
• Use a headset or speaker phone to avoid neck and shoulder discomfort if you use a phone frequently throughout the day.

CHAIR ADJUSTMENTS

Contrary to popular belief, sitting, which most people believe is relaxing, is hard on the back. Sitting for long periods of time can cause increased pressure on the intervertebral discs — the spongy discs between the vertebra. Sitting is also hard on the feet and legs. Gravity tends to pool blood in the legs and feet and create a sluggish return to the heart.

The following recommendations can help increase comfort for computer users:

• "Dynamic sitting", don’t stay in one static position for extended periods of time.
• When performing daily tasks, alternate between sitting and standing or take small walking breaks throughout the day.

When I was a kid, there were all these books that specified the "proper" study space for peak performance and to make getting homework done. Those people are know designing workplaces.

All I know is that my well-meaning parents gave me an outstanding desk and study area that was never used (ok, I used it to dump clothing on). I curled into a ball on my bed and did my homework. It never hurt me.

Well Mr.Accer !! Nowadays we are being dumped by homework all the days.You will do it at the max of 2 hours and also you were youth at school days.But when you start working for 8-12 hours a day continuously and mainly at the time when you have successfully got over 24-26 years of age,your body will disobey to your words and thoughts.Hence,we have to follow this thing to help ourselves right?

# Keyboards. Be sure to get the height right to prevent too much bend at the wrist and allow the forearm to have some support. The arms should hang loose to prevent the shoulder muscles from cramping. Many keyboards can tilt; unfortunately, most of them tilt the wrong way. If any thing the keyboard should tilt to help the wrist stay straight, which is to say raising the space bar end and lowering the "top"(the F1, F2 etc.) end. Tilting the key board the other way, (space bar lower and "top" row higher) can predispose you to carpel tunnel syndrome.

# Mouse. The continual clicking and small, precise motions involved in mouse use are a repetitive action that can be a health hazard. A few basic rules can help make handling this convenient input devise safer and more comfortable:
1.) Hold the mouse loosely. "White knuckling" the mouse creates too much tension. Use a light touch when you click.
2.) Use you whole arm and shoulder to move the mouse, not just your wrist. Don't rest your forearm on the desk while you move the mouse.
3.) Do not lift your "pinkie", use all of your fingers to lightly hold the mouse.
4.) Keep your wrist relaxed and neutral, not bent. The click button should be about the same height as your keyboard.
5.) Avoid prolonged postures. Rotate your shoulders, gently shake your hands and fingers four or five times per hour.
6.) Left handers should use a "left handed" mouse, or configure the mouse to work best with their different (mirror image) hand shape.
