•
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
ergonomic 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
