It isn't just
your personal safety you need to consider when using computers and
the Internet, you should also think about your health and comfort.
Using computers regularly can cause all sorts of health problems,
from headaches to repetitive strain injuries. However, if you
follow these simple guidelines, using a computer need not be such
a pain!
- Adjust your chair so that the
back rest supports your lower back.
- Adjust the seat height so your
arms and wrists are straight as you type. Don't rest your
wrists on the desk and don't press the keys too hard or
overstretch your fingers.
- Use a foot rest if your feet
don't reach the floor.
- Don't sit too close to the
screen. You should be at least an arms length away (probably
about 40-60 cm depending on your height). Adjust the screen
height and angle so that you are comfortable looking at it (if
you need to look at the keyboard to type, the monitor should
point downwards slightly so you don't have to move your neck
too much).
- Use a document holder if you are
typing up a piece of written work.
- Position the computer so that you
don't have to look at a window or a bright light. Also avoid
having reflections of windows or lights on your screen.
- Keep the screen clean!
- Break up your work with other
activities which don't involve similar wrist movements
(preferably get up and walk around). Spend 10 minutes of every
hour doing something else away from the screen.
- Wear glasses or contact lenses
for computer work if you need to.
- If you feel ANY pain or
discomfort which you think is to do with your use of
computers, tell an adult as you might need to see a doctor.
