Advice for Your Health
Prolonged use of a computer may affect your health. Keep in mind the following to
reduce stresses on your body:
Sit in a good posture
Sit on your chair with your back straight. If the desk height is appropriate, you will
slightly look down at the screen and your forearms will be parallel to the floor. This
"good" work posture can minimize muscle tension caused by sedentary work.
If you sit in a "bad" posture—for example, sit round-shouldered or with you face too
close to the display—you may easily suffer fatigue or have your eyesight affected.
Adjust the installation angle of Display
Most types of displays allow you to adjust the angle vertically and horizontally. This
adjustment is very important to prevent the reflection of light as well as to make the
screen more comfortable to see. Without this adjustment, it is difficult to maintain a
"good" work posture and may get tired soon. Be sure to adjust the angle before using
the display.
Adjust Brightness and Contrast
Displays allow you to adjust brightness and contrast. Optimum brightness and contrast
vary depending on the individual, age, brightness of the room, etc; you need to make an
adjustment accordingly. If the screen is too bright or too dark, it is bad for your eyes.
Adjust the installation angle of Keyboard
Some types of keyboards allow you to adjust the angle. If you adjust the angle to make
the keyboard more comfortable to use, you can greatly reduce stresses on your
shoulders, arms, and fingers.
Clean the Equipment
Cleanliness of the equipment is very important not only for reasons of appearance but
also from the viewpoints of function and safety. Especially, you need to regularly clean
the display, which gets unclear due to the accumulation of dirt.
Take a break when you get tired
If you feel tired, you are recommended to refresh yourself by taking a short break or
doing a light exercise.
