	to feel tired. Frequent short breaks are helpful in reducing fatigue.

m Some computer users may develop discomfort in their hands, wrists,

or arms after periods of intensive work without breaks.

If you begin to develop chronic pain or discomfort in your hands,

wrists, or arms, consult a qualified health specialist immediately.

m Allow adequate workspace so that you can use your keyboard and

mouse comfortably. Place papers or other items so you can view them

easily while using your computer. A document stand may make reading

papers more comfortable.

m Eye muscles must work harder to focus on nearby objects.

Occasionally focus your eyes on a distant object, and blink often while

you work.

m Clean your screen regularly. Keeping the screen clean helps reduce

unwanted reflections.
