The human body was not designed to spend long hours each day sitting in the same position, staring at a computer screen, typing on a keyboard, and pushing around a computer mouse. But in today's world, that is the unavoidable reality in which many of us live. The science of ergonomics (or human factors) focuses on ways to make work more comfortable, and as a result, also less likely to cause repetitive stress injury (RSI). For those who spend 8 to 12 hours a day in front of the computer, you may well already be experiencing some form of lower back or wrist pain. After learning more about ergonomics, and the ways in which you can set up your work station with the proper devices, you can alleviate pain while also improving productivity.
