tion-free as possible, with background noise below 58 dBA. Where possible, relative air humidity should be in the range of 40 to 60 percent. Recommended room temperature is 19 to 23 ºC (66 to 73 ºF).

Reducing eye strain

Have your eyes checked on a regular basis and ensure your eyeglass prescription is suitable for working on a computer screen. Look away from the screen from time to time. Focus on distant objects briefly. Blinking periodically helps to lubricate the eyes.

Preventing muscle stiffness

Avoid holding your muscles tense for long periods of time. Keep your fingers and body relaxed. Changing tasks fre- quently 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 pro- longed 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.
