Headache Hello! A lot of people often complain about headache while working at the computer, because many of us work at office. If you have a such problem I would recommend you straighten your back - such way your head will be a bit higher than before, and your eyes will see on the screen slightly from top to bottom. Then make sure that your screen is perpendicular to your eyes. Adjust the screen if it isn't. Having done this many people feel relief.
