But all of these simple tasks allowed our bodies to take many micro-breaks during the day. Now we may not be doing that. In that 30 seconds, stretch your wrist, roll your shoulders and neck, and focus your eyes on a distant point. These micro-breaks will allow your body some recovery time and will reduce repetitive stress. Your work station should be set-up to fit you.
Some basic guidelines are as follows.
The monitor should be situated so that when you look at the top of the viewable screen your neck is not bent either up or down. That means that bifocal wearers will want it lower then others so they are not craning their neck to see the screen. The chair, keyboard, and monitor should be in a straight line so you are not twisting your neck or back to see that screen and use that keyboard. Your mouse should be located near your keyboard at about the same height, so you don't have to reach to use it. Your chair is one of the most important tools in your office.
