  • Page 9: Important Choices

    ROMOTING A AFE AND Posture, lighting, furniture, work organization, and other work conditions and habits may affect the way you feel and how well you work. By adjusting your work environment and personal practices, you may be able to minimize fatigue and discomfort, and reduce the risk of resulting strains that some scientists believe can lead to injury.

  • Page 10: Promoting A Safe And Comfortable Work Environment

    ROMOTING A AFE AND Key Principles To promote safety and comfort, follow these principles whenever you use your computer. OMFORTABLE NVIRONMENT ADJUST Adjust your body position and your work equipment. There is no one “right” position. Find your comfort zone, as described in this Guide, and when working at your computer, frequently adjust within this zone.
  • Page 11 RELAX Build positive relationships at work and home. Relax and strive to reduce sources of stress. Stay aware of physical tension such as clenching your muscles and shrugging your shoulders. Continually release tension. Take frequent short breaks. LISTEN Listen to your body. Pay attention to any tension, discomfort, or pain you may feel, and take immediate action to relieve it.

  • Page 13: A Range Of Positions

    INDING OMFORT A Range of Positions Rather than working in a single posture, find your comfort zone. Your comfort zone is a range of positions that is generally appropriate and comfortable for your given work situation. Move Sitting still for long periods can cause discomfort and muscle fatigue.

  • Page 14: Finding Your Comfort Zone

    INDING OMFORT Feet, Knees, and Legs Make sure your feet can rest solidly and comfortably on the floor while sitting. Use an adjustable worksurface and chair that allow your feet to rest firmly on the floor, or use a footrest. If you use a footrest, be sure it is wide enough to accomodate different leg positions within your comfort zone.

  • Page 15: Back

    Back Use your chair to fully support your body. Distribute your weight evenly and use the entire seat and backrest to support your body. If your chair has adjustable low back support, match the contours of the chair’s backrest to the natural curve of your lower spine.

  • Page 16: Forearms, Wrists, And Hands

    INDING OMFORT Forearms, Wrists, and Hands Keep your forearms, wrists, and hands aligned in a straight, neutral position, whether you are working at a desk or table, or sitting on a couch or bed. Avoid bending or angling your wrists while typing or using a pointing device.
  • Page 17 RIGHT Hold a straight, neutral wrist position while typing. WRONG! Don’t angle your wrists; this may cause unnecessary strain. Split Keyboards If you find it difficult to type with a straight, neutral wrist position, you may want to try a split keyboard. Be aware, however, that improper setup or posture while using a split keyboard can increase bending in your wrists.

  • Page 18: Shoulders And Elbows

    INDING OMFORT Shoulders and Elbows Adjust your chair height or keyboard height so that your shoulders are relaxed and your elbows hang comfortably at your sides. Adjust your keyboard slope so that your wrists are straight. Checking Elbow Height Position your elbows in a zone that is near the height of your keyboard’s home row (the row that includes the letters G and H).

  • Page 19: Eyes

    Eyes Working at your computer for long periods can be a visually demanding task and may cause your eyes to become irritated and fatigued. Therefore, you should give special attention to vision care, including the following recommendations: Resting Your Eyes Give your eyes frequent breaks.
  • Page 20 BLUR SECTION PHOTO - HOME OFFICE, WOMAN MODEL, OVERHEAD SHOT, BOOKS, REFERENCE PAPERS AND PHONE PLACED WITHIN EASY REACH, CHAIR WITH ARMRESTS Positioning Your Monitor You may find a range of monitor heights that allows your head to be balanced comfortably over your shoulders.
  • Page 21 If this places the monitor too high, you may want to move the the monitor to the desktop. On the other hand, if the monitor sits on your work surface and you feel any discomfort in your neck or upper back, the monitor may be too low.

  • Page 22: Arranging Your Work Area

    RRANGING Adjusting Monitor Height for Bifocal and Trifocal Users If you wear bifocals or trifocals, it’s especially important to properly adjust your monitor height. Avoid tilting your head back to view the screen through the lower portion of your glasses; this could lead to muscle fatigue in your neck and back.

  • Page 23: Monitor

    Eliminating Glare and Reflections on Your Monitor Take the time to eliminate glare and reflec- tions. To control daylight, use blinds, shades, or drapes, or try other glare-reducing measures. Use indirect or reduced lighting to avoid bright spots on your display screen. If glare is a problem, consider these actions: Move your monitor to a place where glare and bright reflections are eliminated.

  • Page 24: Keyboard And Pointing Device

    Otherwise, you will probably place the mouse on your desktop, higher and farther away than the keyboard. This will lead you to stretch forward repeatedly, and uncomfort- ably, to reach the mouse.

  • Page 25: Arm Supports And A Palm Rest

    Arm Supports and a Palm Rest You may find that supports for your forearms or hands allow you to be more relaxed and comfortable. Using Arm Supports Some chairs and desks provide padded areas for resting your arms. You may find it comfortable to rest the middle of your forearms on these supports while typing, pointing, or pausing.

  • Page 26: Papers And Books

    RRANGING Papers and Books Select a work surface or surfaces that are large enough to hold the computer equip- ment and any additional items required for your work. To help minimize eye fatigue, position any materials to which you fre- quently refer at about the same viewing distance.

  • Page 27: Phone

    Phone Cradling your phone between your ear and shoulder may lead to neck, shoulder, and back discomfort. If you use your phone a lot, try using a headset or positioning your phone so you pick it up with your non- dominant hand.
  • Page 28 Road In a hotel, use a blanket for padding your chair and a rolled towel as an inventive way to support your lower back area.

  • Page 29: Using A Notebook Computer

    Using a Notebook Computer Maintaining a high level of comfort when using a notebook computer may be more challenging than when using a desktop computer. Therefore, you should be espe- cially alert to your body’s signals, such as any feeling of discomfort. Also, be sure to adhere to the key principles presented earlier in this Guide.

    ORKING IN OMFORT Typing Style Observe your typing style and notice how you use your fingers and hands. Avoid keeping any unnecessary tension in your thumbs and fingers. Observe whether you have a heavy touch or a light touch while typing.

  • Page 31: Pointing Style

    Pointing Style Use your whole arm and shoulder to move the mouse, not just your wrist. Don’t rest or anchor your wrist while using your pointing device; keep your wrist, arm, and shoulder free to move. Adjusting Software Controls You can use the software control panel to adjust the properties of your pointing device.

  • Page 32: Using A Keyboard On A Sofa

    ORKING IN OMFORT Using a Keyboard on a Sofa Even if you use your keyboard in a seemingly comfortable place such as a sofa, bed, or your favorite lounge chair, you can still cause discomfort by sitting in an awkward position or in one position for long periods.

  • Page 33: Taking Breaks And Varying Your Tasks

    Taking Breaks and Varying Your Tasks As noted earlier in this Guide, your furniture placement, office equipment, and lighting are only a few of the factors that determine comfort. Your work habits are also very important. Remember the following: Take Breaks When you work at your computer for long periods, take short breaks at least once per hour and preferably more often.

  • Page 34: Monitoring Your Health Habits And Exercise

    ORKING IN OMFORT Monitoring Your Health Habits and Exercise The comfort and safety of working at your computer can be affected by your general state of health. Studies have shown that a variety of health conditions may increase the risk of discomfort, muscle and joint disor- ders, or injuries.

  • Page 35: Ordering Your Adjustments

    RDERING The order in which you follow the advice in the proceeding chapters depends on the adjustability of your work surface. If your work surface height adjusts, then systematically adjust yourself and your computer “from the ground up.” If you have a fixed desk or table, systematically adjust yourself and your computer “from the top down.”...
