I work at a safety organization and just finished putting together an office safety presentation for our trainers. I created the ergonomics portion as a separate presentation last fall, so you'd think I'd have realized this sooner, but my situation is different.
Something hit me today. It's happened a couple of times, but just little ticks, not the big knock that finally hit me today. I realized long ago that there was a musculoskeletal component to the air hunger that I've been experiencing. Stretching and massage have always provided temporary relief but hasn't kicked it out completely.
My work monitor, chair, keyboard tray, and foot stool all put me in the perfect position...for a normal visioned person. I am not normal; I wear bifocals. I've had them for so long that I don't often think about what I'm doing; I don't realize how I adjust my head to see things through the different parts of the lenses.
I realized today how far back I tip my head to read through the bottoms of my bifocals. I have to tip my head back farther than a normal person to read on my monitor, no matter the resolution. (Yes, my eyes are THAT bad!) I never have to do that at home when I have my laptop on my lap and I feel better and breathe easier.
So, I stood up and realized that, although my head is above the monitor, it was in the right position so that I wasn't straining my neck and shoulders to hold my head back to read through the bottoms of my glasses. It was actually perfect, partly because I'm so short. As an added bonus, the portion of my desk for my keyboard and mouse is adjustable and at it's highest is perfect for me standing. So, I have a standing desk! I was amazed at how much my shoulders stretched when relaxed and how much more comfortable I was looking down at my screen instead of up. And the air hunger improved slightly. It will take time to see if I'm on to the source of that problem, but if nothing else, I am more comfortable at my desk at work and am not just sitting on my butt all morning.
I've seen different ergonomics pictures, and most show the monitor below the level of the user's head for proper alignment. I'm hoping the new position helps correct this issue or at least lessen it (there may still be a physiological cause). I still have my other health issues, but only the insomnia is as frustrating as the air hunger. Everything else is a cake walk by comparison.
