4 Working in Comfort
Overall
• Look away from the screen from time-to-time to help reduce
eyestrain. Focus on distant objects briefly, and blink periodically to
lubricate your eyes. You also should have your eyes checked on a
regular basis and ensure your eyeglass prescription is suitable for
working on a monitor screen.
• Remember to occasionally shift position and move your body. Keeping
your body in one position for long periods is unnatural and stressful.
When prolonged work is required, take frequent short breaks. As a
rule of thumb, a five or ten minute break every hour is a good idea.
Short frequent breaks are more beneficial than longer less frequent
breaks. Data show that people who work for long periods of time
without a break may be more prone to injury.
• Changing tasks frequently will help prevent muscle stiffness.
Examples: alternating between keyboarding, reading, writing, filing,
and moving around in your work environment, helps you maintain a
relaxed posture. Occasionally stretch the muscles in your hands, arms,
shoulders, neck and back. You should stretch at least as often as you
take brief task breaks—at least once every hour.
• Discomfort may be alleviated by using alternative ergonomic designs
and accessories such as ergonomically personalized chairs, palm rests,
keyboard trays, alternative input devices, prescription eyeglasses,
anti-glare screens, and more. Seek additional information from the
sources available to you, including your employer, doctor, local office
supply store, and the Information Sources listed in the online version
of Working in Comfort, preloaded on the hard disk of your HP
computing equipment.
