How to make your office more ergonomically correct? Here are some ideas

A healthy workstation is one that allows you to work in a neutral, relaxed position.

Last month, I bought a big new computer screen, thinking that if I stopped crouching over my laptop like a turtle, my lower back would stop hurting. It worked great — for about 48 hours. Then I started getting searing pains in my neck, which prevented me from turning my head to the right, which then almost got me into a car accident. All because, I eventually figured out, I had positioned my new screen about two inches too high.

About $1 billion a week is spent in the United States to deal with entirely preventable work-related musculoskeletal injuries, many of which are caused by small flaws in body positioning. You can do a surprising amount of damage to your body if you hold parts of it in strange positions for hours at a time, five days a week. But some research suggests that you can also prevent and even reverse damage by engineering your work environment properly. I talked to experts to find out how.

If possible, invest in ergonomically sound furniture. A healthy is one that allows you to work in a neutral, relaxed position. That setup “requires the least force, the least strength, the least effort,” said Alan Hedge, director of the Human Factors and Ergonomics Research Group at Cornell University, “and that means you’re putting the least amount of strain on your body.”

To get there, you will want furniture that can be adjusted to your body size and shape — basically, “the more adjustability, the better,” said Justin Young, an industrial and operations engineer at Kettering University in Michigan.

Your chair is important. Ideally, you want one with adjustable height and lumbar support, that reclines and that also supports the upper and middle back. The seat pan should be at least one inch wider than your hips and thighs on either side, and not so long that you can’t sit all the way back without the edge hitting you behind the knees.

Very few people sit back when they work, but they should, Hedge said, because when you recline, more of your body weight is supported by your chair, rather than supported by (and also compressing) your spine. Chair arms are not essential, but they can support you as you stand up and sit down.

Desks can be tricky for a computer user, because most desks are built at the correct height for writing, not typing. You don’t want to have to hunch up your shoulders to type, for example, nor do you want your wrists bending up or down — an ideal keyboard height is about two inches above your knees.

If your desk is too high, one solution is to get a keyboard tray that slides out from under the desk and slopes downward, or has what is called a “negative slope,” because that slope keeps your wrists in a vertically neutral position. A split keyboard, like one of these ergonomic models, can keep wrists in a horizontally neutral position as well.

As for sitting versus standing desks: The research is mixed on terms of what is better, so it really depends on what feels good to you, Dr. Young said. Sit-stand desks, on the other hand, have the distinct advantage of encouraging you to change positions regularly, which is good for your body. If the furniture you have does not allow you to work in a neutral position, make tweaks with what you have — create lumbar support with a pillow or pad, for instance. Then ask your employer for an upgrade.

When employees work safely and comfortably, they are less likely to get injured and miss work and are also more motivated and productive.

Position your gear properly and use smartphones carefully. Once you have adjusted your work space, don’t overlook the tools you use to do your job. The goal is, again, to keep your body as neutral as possible, so adjust your equipment to make that happen.

Is your mouse way off to the side? Bring it closer to your body so you don’t have to reach so far. Your keyboard should be set so that the “B” or “H” key is at your midline, and your monitor should be straight in front of you and a height such that you do not have to tilt your neck down or up to see it. (That was my downfall.)

If you frequently look at papers, consider getting a document holder and keeping it close to your monitor so you do not have to move your head as much. Adjust your chair so your feet are flat on the floor, your legs are bent at a right angle and you can work in a reclined position.

Smartphones present unique problems. For one thing, they increase the risk for “texting thumb”, or de Quervain syndrome, an irritation of the tendon or tendon sheath on the outside of the thumb. Hedge suggests downloading a swipe-to-type keyboard app, which uses predictive text and finger swiping and is much easier on the thumbs. Even better, dictate texts. And if you talk on your phone a lot, invest in a handset so you do not have to hold it up to your ear. When looking at your phone, don’t hold it down near your chest or waist, because you have to look down to see it, which strains your neck muscles.
