Having worked as an occupational therapist in that area, I can attest that there are many occupational health issues related to IT work.Some are obviousu2014cumulative trauma as the result of long-held postures and repetitive motion. The nerves in the wrist and at the elbow are often subject to trauma, due to consent keyboard and mouse work, particularly when the level of the work surface cannot be adjusted. The ability of chair adjustment is also a factor. The result is a posture that reduces blood flow to the upper extremities and facilities the onset of trauma.Another factor is sustained work and posture without change of position or change in the activity. IT workers can become very focused on their work and much time can pass without any relief of their position. Itu2019s simply not easy to take programmed breaks in programming! If the work is support, add the stress of customers on the other end setting your schedule for you.Screens are getting much better, but there is still significant eye strain, and there is growing evidence of the negative effects of certain colors/temperatures of light. And into this you have to consider ambient room lighting.Because many workers are young, there is less incidence, thankfully, but as they age the problems can evolve.Another area not often realized is back injuries. IT staff often have to install servers or batteries that are hefty, into small closets. And being IT workers, they generally are not in shape for such lifting, or may not be provided the equipment to minimize the loads. And sometimes it just canu2019t be done safely.The best approach is prevention. It is unlikely that employers are going to rush out and meet your postural needs, but workers can choose a discipline of timed breaks, if only to stand and stretch. Sadly, most don't until they have issues. Good sleep and diet, and regular exercise is very helpful. Again, this is not common, unless the person simply focuses on those issues normally in their lives.One of the growing issues is the growing trend towards laptop use. Itu2019s simply hard to modify a laptop for good ergonomics, unless keyboards and pointing devices, and larger screens are added.
