Computers and body fatigue

Computer users sometimes experience such discomfort as back pain, stiff neck and shoulders, sore hands and wrists, or tired legs. Much of this discomfort can be prevented because the symptoms often arise from pushing the body beyond its natural limits. In addition to improving the setup of your work-space, it's also important to consider your lifestyle. Healthful food, exercise, and rest can help improve your health and comfort. Seek medical assistance for any persistent discomfort. Minimize the following actions:  

  

1. Sitting in awkward or twisted postures.
2. Maintaining the same posture for too long.
3. Using too much muscular effort, even for relatively easy tasks.
4. Pressing on the soft tissues of your body - for example, leaning your arms against a hard desk edge.
5. Performing repetitive tasks that require awkward body positions or forceful exertions,without allowing the body a chance to recover.
