Computing in comfort

　　When setting up a computer workstation, especially at home, we tend to use whatever furniture we have handy. But "making do" may cost you more than it saves in the long run[1], due to decreased productivity and increased medical expenses. The more time you spend in front of the computer, the more important it is to adjust your workstation. Eventually it will fit your body like custom-made clothing[2].

　　If you come away from a session at your computer with aching hands or eyes that feel full of sand, you may shrug off your discomforts as an unavoidable consequence of too much time at the keyboard. But the real problem probably isn't the quantity of time you spend at the computer. It's more likely caused by your physical positioning at the computer. Here are some tips[3] on how to arrange yourself and your computing environment for optimum health and comfort.

　　Physical proportions vary widely between individuals, yet we sit at mass-produced, one-size-fits-all desks. And like automobile seat belts, they're usually too big for women. Working at a desk that's too high off the floor can lead to all sorts of aches and pains[4], especially in your shoulders and neck. It can also trigger early fatigue and interfere with your ability to concentrate. A desk that's too low can also have physical repercussions, including an aching neck and upper back. If resting your forearms on your desk causes your shoulders to rise upward, the desk is probably too tall. If your knees continually bump[5] against the underside, even when your feet are flat on the floor, it's probably too short.
