Computerworkanddiscomfort电脑工作和不适.ppt

Eye strain, neck and shoulder stiffness and low back pain - these are some symptoms you may experience when working with computers. Having to keep the same posture over long periods of time is one of the main causes of physical discomfort. Improperly positioned keyboards or mouse also contribute to the discomfort. At the early stages of pain, the symptom disappears when a person stops working with the computer. The potential to develop work-related musculoskeletal disorders (WMSD)*1, however, increases when computing tasks continue despite the presence of body aches. These musculoskeletal disorders would persist until well after work has ended. 眼睛疲劳，脖子和肩膀僵硬，腰背酸疼－这些都是你在使用电脑时可能会有的症状。长时间的保持同样的动作是其中一个主要的原因。不正确的使用键盘和鼠标也会导致不适。在酸痛症状的初期，当停止使用电脑时就会消失。但是会有潜在发展成为WMSD。然而，随着电脑工作的持续身体的疼痛感就会增加。这样的不适感直到工作完全结束后才会减轻。 Staring continuously at the monitor is another cause of discomfort from computer work. Furthermore, computer work tires the eyes because the short distance visual task puts much stress on the eyes adjustment mechanism. In effect, workers complain of symptoms of eyestrain that include dry eyes*2, eye irritation, burning sensation in the eyes, and blurring of vision. Though the symptoms do not progress to permanent vision problems, eye strain negatively affects productivity at work and more significantly a workers attitude towards computing tasks. In addition to the above health problems, devoting so much time to computer work may lead to mental stress. Social isolation results from decreased opportunity to talk and interact with co-workers and less chance to foster social support that helps reduce stress.　持续的注视显示器也是造成不适的另一个原因。此外，电脑作业造成眼部疲劳是因为长时间短距离注视会对眼睛自身的调节机制造成很大的压力。实际上，员工眼部疲劳的症状包括眼睛干涩，眼睛刺痛，眼部有灼热感和视觉模糊。尽管这些症状不会发展成为永久的视力问题，眼部疲劳会对工作效率造成负面影响，更为值得注意的是，会使员工对电脑作业产生厌恶感。除了上述的健康问题，过多的电脑工作将导致精神压力。减少与同事之间的交谈和联系的机会会造成社会隔离感和减少获取减少压力的社会支持的机会。 ※1Work-related Musculoskeletal Disorders (WMSD) are disorders of the muscles, ligaments, tendons, nerves and bones that result from unfavorab
