Preventing muscle stiffness
Avoid holding your muscles tense for long periods of time. Keep your
fingers and body relaxed. Changing tasks frequently helps prevent muscle
stiffness. Alternating between typing, writing, filing, and moving around in
your work environment helps to keep muscles loose.
Taking frequent short breaks
When you are required to work on your computer for prolonged periods of
time, take short breaks frequently. As a general rule, a 5- and 10-minute break
every hour is a good idea. It is better to take short breaks frequently than
longer breaks less frequently. Data shows that people who work for long
periods of time without a break are more prone to injury. Occasionally stretch
the muscles in your hands, arms, shoulders, neck, and back. You should
stretch at least once an hour.
