The rapid and correct performance of computers, when accompanied by human skills, will lead to greater gains in productivity. This study focuses on the possible risks of computer use in terms of human health, rather than on the countless beneficial effects of its use on the issue of health. Health problems caused by inappropriate or inadequate use of computers or by using it at no time are mentioned under two headings: psychological problems (fear of technology, computer anxiety, dependence on the internet and so on) and physical problems (repetitive strain injury, carpal tunnel syndrome, computer vision syndrome, electronic waves, sleep disorders and so on). Considering the results of previous studies, this study discusses the precautions necessary to be taken for each of the psychological and physical problems likely to be caused by the use of computers.
