You and Your Computer – Minus Eyestrain Or Back pain

Pop quiz: Count yourself, your circle of family, friends and your co-workers. How many of you spend significant time on your computers?

Done? Now, how many of you say anything about headaches, or dry eyes?

Research shows that roughly 70% of the people who work with computers have problems with their vision. That breaks down to 7 out of 10 people. Does this figure agree with your findings?

Computing is an overwhelmingly visual media and it’s because of this that so many people suffer from visual fatigue and computer vision syndrome . Most studies show that 70-90% of computer workers show symptoms of vision-related problems, bought on by a combination of poor workplace conditions, individual visual problems, and improper work habits.

For example, in a normal setting people normally blink around 17-22 times per minute. On the computer, they slow down to 4 blinks a minute. The normal flow of tears that lubricate your eyeballs and wash out any possible irritant is compromised. Result: Dry, irritated “sandy” eyes.

And that’s not all!

Have you ever seen little kids crouch over something of interest and bend down even lower? Adults do it too, in a more dignified manner. We hunch towards the focus point and lead with our head. Humans evolved this way. We’re sight-hunters. But millions of years of evolution have a rather painful effect when adapting to today’s demands.

See, to ease the strain bought on by focusing, we change our posture. We lean forward, lean back, cock our heads, and tilt them back…all the while forgetting to release the tension in the supporting muscles. This leads to intense pain in our trapezius once we get up and away from our desks. And since everything’s connected (the shifting, straining, hunching, non-blinking) the lower back gets pulled in and complains as well.

Interesting data:

In Googling for the answer to “What is the average weight of a human head?” we received these responses:

– “An adult human cadaver head cut off around vertebra C3, with no hair, weighs somewhere between 4.5 and 5 kg, constituting around 8% of the whole body mass.”

– It weighs about 5 kilograms or 12 pounds.

So you’d get an idea of where this is going, “Pros almost always use a 16 pound bowling ball. In rare cases, when a pro has an injury to their wrist or arm/shoulder, they will use a 15 pound ball.”

Think of it. All your muscles working together, stomach girdle to hold you upright, working in concert with your back and your neck muscles, to hold up a bowling ball.

– If you’re in shape, that a plus.

– If you’re in shape and you slouch, that’s not.

– If you’re not in shape and you slouch…do something about it. It’s not the computer. It’s you.The computer can’t move by itself. And, a computer doesn’t hurt.

Here are a few tips to deal with eyestrain:

– Blink. Blink more: Blinking gives your eyes for a short time, and it also cleans and lubricates the surface of your eyes to maintain clear vision. Use artificial tears if you need them.

– Breathe. Breathe deeply: When you’re all focused and tense in front of the monitor, remember not to hold your breath. Oxygen deprivation can impair your judgment; make you feel woozy, drained or cranky, weakening your brainstorm to a brain-fart. Plus, tensing up like that for long periods is a major pain in the lower back. Sit properly and take good, regular breaths.

– Have a break: Get neat software like Workrave or Xwrits. Use the alarm on your cell phone to sub for an egg-timer. Be creative.

– Have your eyes checked: There may be a deeper issue to your condition other than improper use of the monitor.

– Change your set-up: After you get your eyes checked, you may have to deal with things differently. Check out anti-glare screens, different lighting, or higher refresh rates on your CRT monitor. Change the settings to enlarge the font size on your screen.

Now for back pain:

Aside from the obvious – consult a qualified physician, exercise, exercise proper posture, stretch, for Pete’s sake etc, you know this already, it’s a question of “Yes, I can. I will” – perhaps you can look up Nada and see if their back support systems can help. They have cool stuff; you might find their Nada-chair to be the best thing to happen to you since the Internet.

If you’re the handy type of person and you prefer DIY projects, why not look for Tom Miller’s Woodware Designs  (“Plans for low-stress computer furniture you can build”) and see what catches your eye. The site also has free plans available for desks, shop furniture and more.

Is Your Computer Causing Your Back Pain ?

How do you feel after a long day of sitting behind your computer? Do you experience headaches or neck and back pain ? If you do, you are not alone. Many people with desk jobs find that the mere act of sitting all day sends them home with discomfort that can keep them from enjoying their favorite leisure time activities. Sitting places pressure on the back and neck, and improper posture from slouching or hunching over the keyboard exacerbates the problem. If your computer is causing back pain , there are some steps you can take to alleviate the discomfort and prevent further pain.

Ergonomics

The first step in easing back pain is to find an ergonomic chair that will help you maximize support to your back and encourage better posture. Once you have found the ergonomic chair that is most comfortable to you, the next step will be to adjust it so that it conforms perfectly to your unique body proportions. This will relieve pressure to your back while you are sitting and keep your spine aligned properly throughout the day. There are many measurements you can check to ensure that your chair is properly adjusted, but the main rules are to make sure your elbows are at a 90° angle and your computer screen is at eye level. Another important adjustment is to the armrest, which should raise your arms just slightly at the shoulder to take pressure off the shoulders and neck area.

Stretching

The other important component to preventing back pain while working at your computer all day is to ake frequent breaks for stretching. Take a minute or two every half hour to stand, walk or stretch your muscles that are becoming strained from a single position. Even a brief stroll to the water cooler or bathroom will give your back the break it needs during the day and help prevent back pain . If possible, take a longer walk at lunchtime that will increase your circulation and nourish the spine and surrounding muscles. By sticking with a regular exercise program every day that includes core strengthening, such as weight training or yoga, you can also do much to prevent future back pain from occurring.

Back pain is a common problem with those who sit in front of a computer screen all day, but the good news is that there are steps you can take to alleviate the problem. Find an ergonomic desk chair and adjust it to fit your individual body proportions. Take frequent breaks during the day to stand, walk and stretch. Finally, stick with a regular exercise program that will strengthen the back and prevent problems before they occur. Your back will be less painful for it and your days will be more productive.
