Avoiding Fatigue
mChange your seated position, stand up, or stretch whenever you start to feel tired.
Frequent short breaks are helpful in reducing fatigue.
mUse a light touch when typing or using a mouse and keep your hands and fingers relaxed.
mSome 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.
mAllow 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.
mEye muscles must work harder to focus on nearby objects. Occasionally focus your eyes
on a distant object, and blink often while you work.
mClean your screen regularly. Keeping the screen clean helps reduce unwanted reflections.
What About Electromagnetic Emissions?
There has been recent public discussion of the possible health effects of prolonged exposure
to extremely low frequency (ELF) and very low frequency (VLF) electromagnetic fields. Such
fields are associated with electromagnetic sources such as television sets, electrical wiring,
and some household appliances—as well as computer monitors.
Apple has reviewed scientific reports and sought the counsel of government regulatory
agencies and respected health organizations. Based on the prevailing evidence and opinions,
Apple believes that the electric and magnetic fields produced by computer monitors do not
pose a health risk.
In response to those customers who wish to reduce their exposure to electromagnetic fields,
Apple has lowered the emission levels of our products. We have also promoted further
scientific research so we can continue to promote the health and safety of our customers and
employees.
