Windows and Mac users actually do have one thing in common - computer ergonomics issues, namely, pain.^1,2 Beyond the usual hardware and software gotchas we deal with on a daily basis, the real bottom-line question is, "how to play nice with my computer".

Doing computer work is a funny kind of work, a type of activity we're still getting used to. It's not physical work in the sense that there's no heavy lifting going on, no truck-driving, no emergency services heart-pounding decision-making.

But computer work is still an intensely physical activity, although the work is pretty subtle. In computer work it's the small muscles that are getting the workout, not the big muscles we're used to thinking about.

Wrist muscles, tendons, and ligaments. Finger muscles, tendons, and ligaments. Shoulder muscles, Neck muscles. All of these are involved in ongoing repetitive tasks when you sit at a computer and one hour turns into two, two hours turns into three, and suddenly half the day is gone and you notice you've got a killer stiff neck.

Or, one day the tendons on the back of your hand begin to hurt, feeling irritated and inflamed. Or your shoulders and upper back are tight and painful.

Your hands or shoulders feel better by the time you go to sleep. But the next day, as soon as you start to type they act up again.

This is all very uncomfortable, because you've got to do your work.

What's going on?

These various pain patterns in your hands, wrists, shoulders, and neck can be grouped together as a repetitive stress syndrome. Repetitive activities, done over a long period of time, can irritate and inflame the muscles, tendons, and ligaments that are involved in doing the work.

But computer work involves repetitive tasks. How can you avoid these painful problems?

The best approach is to prevent them in the first place.³ If such a syndrome does develop, relative rest is indicated. Reduced computer activity, in smaller intervals, is a good solution. A very useful work-around for right- or left-arm pain is to teach your non-dominant hand to use the mouse or touchpad. This training may take a few weeks - the valuable result is the ability to switch hands whenever you like, distributing the workload between the two sides. Much better.

The most important aspect of prevention is to take a quick, refreshing break once an hour. This is a critical habit to develop. Get out of your chair, walk around, get some fresh air if possible. Change your environment for a few minutes - talk to a co-worker for a moment, get a drink from the water-cooler down the hall, seek out a picture, wall-covering, or landscape you've never seen before.

These activities refresh your body AND your brain, and you're ready to do another hour of productive, creative, healthy work. You'll feel much better, you'll be avoiding repetitive injuries, and your workday will be more enjoyable.

Most of us are plenty tired of having experts tell us we should do more exercise. Our chiropractors tell us. Our family doctors tell us. Friends who just started taking their first yoga class and aren't really experts tell us. Celebrities tell us. Kid stars on Disney Channel tell us. Now even local television news anchors are telling us.

Intentionally or not, the result of all this "encouragement" is just more and more guilt. We already know we should be exercising. Hearing about it all day long really doesn't help. We're working hard at our jobs, keeping it together, taking care of the family, but as long as we're not also doing our daily exercise we're just not doing enough. We're not being healthy and the experts are only too glad to recite all of the long-term consequences of our slothful behavior.^1,2,3

So what's a person to do? On one hand, we can dig in our heels, deny reality, and desperately resist all those do-gooders. Some will bet their future on ancient family legends - "My grand-dad smoked two packs of cigarettes for 50 years, never exercised a day in his life, and died in his sleep when he was 92." Others will simply leave things up to fate, taking their chances as well as the path of least resistance, doing the same old same old, and hoping everything will be OK.

There is another way. First, it's very important to distinguish what I choose to do from what I should do. No one wants to do what they should do. Should means having to, should means having no choice in the matter. Should means someone else is telling me what to do, and no one really wants to do that. We want to do what we want to do. So telling a person they should do more exercise merely engenders resistance. People will only take the time and make the effort to exercise regularly if they want to do it, if they themselves choose to. Not because someone told them they needed to.

The secret of adding exercise to your life is discovering why you would want to do it. Discovering the payoff. Sure, the payoff includes being healthier, lowering your blood pressure, improving your metabolism, and lowering your serum glucose. But these are not really motivating factors for most people. If they were, everyone would be exercising. The real payoff, what gets people into the gym and out on the road walking, bicycling, and running, is that exercise is fun. You feel great afterward, often for the whole day. And pretty quickly, the more you exercise the more your body wants to do it. Your body takes over and your mind goes, "yeah, I'm going to the gym".

So the secret is to make a choice, pull yourself together, grit your teeth, and go exercising a few times. Almost always you'll discover that you actually do like it, that there's a tremendous feeling of accomplishment and fun. And all of a sudden, to your surprise and astonishment, you've become a person who exercises.

Not too many people would agree that "oh, yeah, my work is relaxing". For most of us, work involves plenty of stress. If we're in customer service, there's always a seemingly never-ending stream of customers with an abundance of problems that need to be handled yesterday. If we work in an office, office politics adds an unnecessary layer of stress to the normal daily stress of the work we're supposed to be doing. If we work for ourselves, there's the ongoing stress of lining up the next contract, even while we're dealing with the pressures involved in fulfilling the demands of the current project. And on and on.

If we work at a computer there are additional physiological stresses. Our bodies were not designed for prolonged sitting, nor were they designed for staring a computer screen for hours at a time. The highly complex and highly delicate structures of our forearms, wrists, and hands were not meant to be used for typing on a keyboard. Anyone can type for 15 minutes - that's not a problem. But typing for most of the day, day after day, week after week - that's definitely a problem.

These few work scenarios are common. We can recognize ourselves in the descriptions. No one would describe such circumstances as relaxing. But this is how we live. How can we turn what might be thought of as "lemons" into lemonade? Are there tactics we can employ in an overall strategy of causing our lives to be healthy, satisfying, and meaningful, as well as fun and relaxing?

The answer is a resounding "yes". But there is effort involved. We need to be creative and willing to take action on our own behalf. First, it's important to acknowledge the conundrum each of us faces every day. We are required to work to obtain food, shelter, and clothing for ourselves and our families. But the work that we're doing may not be our first choice. Or the second choice. Or sometimes even the third. Still, there it is. We need to work. This is where the creativity comes in.

Our work environment and/or our work itself may never be relaxing. However, we can actively choose to be relaxed. This is an ongoing process and occurs in the moment. For example, you can affirm "I am relaxed. My work is fulfilling and satisfying." And then, pretty soon, something happens to which you respond with tension. As soon as you come back to yourself and remember that you want to be creating a relaxing environment, you reaffirm your intention. This is very much like Zen or other practices which focus on centering. In Zen, the student is reminded to pay attention, to believe nothing, and that nothing is personal.

These powerful reminders can help us greatly in our intention to have our work be relaxing.^1,2,3 The key is to take on the concept of practice. We are practicing centering. We are practicing self-awareness. We are practicing relaxing. And as we practice these things, our overall experience is one of being centered, relaxed, and self-aware, regardless of all the things that are going on around us.
