Ergonomics | 145 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.
