For the first time, people started talking about the harmful effects of computers on health almost simultaneously with their appearance. Which is understandable: computers of that time can hardly be called harmless, especially in comparison with modern models. However, even now, even seemingly safe computers have a negative effect on our health. This book examines the possible influence of a computer on the human body. Describes how to properly install a computer and organize a workplace in order to “unload” the spine as much as possible and not strain the hands; how to surf the Internet to avoid problems with the nervous system; how to play computer games without damaging your psyche. Separately, it talks about how the computer affects the health of children and pregnant women. In addition, the book describes useful programs designed to preserve our health (you can find their demo versions on the accompanying CD). All rights reserved.
