Avoiding fatigue

m Change your seated position, stand up, or stretch whenever you start to feel tired. Frequent short

breaks are helpful in reducing fatigue.

m Use a light touch when typing and using the trackpad or a mouse and keep your hands and fingers

relaxed.

m Some computer users may develop discomfort in their hands, wrists, or arms after intensive work

without breaks. If you begin to develop chronic pain or discomfort in your hands, wrists, or arms,
consult a qualified health specialist.

m Allow adequate work space so that you can use your keyboard and other devices 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.
