4 Working in Comfort
62 English
• Legs - Your thighs should be horizontal or angled slightly downward.
Your lower legs should be near a right angle to your thighs. Make sure
there is sufficient room under the work surface for your legs.
• Feet - If after adjusting your chair you cannot rest your feet
comfortably on the floor, use a footrest, preferably one that can be
adjusted in height and angle.
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
