Optimizing ergonomics: Adapt the world to you and not the other way aroundPosted: February 24, 2014
Having the right equipment doesn’t mean we use it correctly. It turns out that usage patterns matter just as much as fancy new office furniture. This post was inspired by a wonderful article that David Kadavy generously interviewed me for. His article explores split keyboards and working wellness. In this post, I go in-depth on some complimentary workplace tools and techniques.
After working on a laptop, smartphone or computer, many people experience discomfort and exhaustion. Back and neck pain and vision problems are very common. Although there are many components that contribute to maintaining health and productivity with digital devices, two factors stand out:
- Ergonomic arrangement: the way the physical environment forces the person to adapt, such as bending over to read and perform data entry with a tablet.
- Work style: the way the person manages themselves to perform the tasks.
Many problems that are aggravated or caused by inappropriate ergonomics can be compensated by changing workstyle. For example, if you bend forward to read the tablet or squint to see the text on the monitor, you can take many movement and stress reduction breaks to compensate for the challenging ergonomics. Having the right equipment, appropriately adjusted, is the focus of ergonomics. Working so that health is maintained regardless of equipment is the focus of work style.
Shoes are a great example. Healthy shoes would look like duck feet–wider at the ball of the feet and toes and narrower at the heel. However, most shoes have pointy or narrow toe boxes. Over time, incorrect footwear becomes a major cause of bunions, foot, hip and back pain for older adults. It causes physical deformity just as the 19th century Chinese practice of foot-binding crippled many women. If you want to run a 100 meter race or a marathon—running shoes are better than high heels. Adapting the environment to you instead of the other way around is the underlying theme of ergonomics.
But even with correctly fitting shoes many people still experience discomfort. Often this is because of misaligned movement patterns. such as their feet point outward while walking instead of pointing ahead. Or they unknowingly favor one leg over the other because many years earlier they broke that leg and adapted their walking pattern to reduce the pain. After walking to avoid pain for a month, this new dysfunctional pattern became habitual and their gait never returned to normal. Changing how you walk or work is the focus of optimum work style. For useful suggestions about workstyle see Healthy Computer Email Tips by Erik Peper.
Many experts have worked for decades on defining optimal ergonomics for using digital devices. The results are always compromises because human beings did not evolve to sit in a chair for hours without movement or read from a small screen in front of them. Nevertheless, the ergonomic setup while using laptops and tablets can be significantly improved. It is impossible to achieve a healthy ergonomic setup while using a laptop or tablet. If the screen is placed so that is easily readable, then the fingers and hands need to be lifted (which often involves lifting the shoulders) to perform data entry. On the other hand if the keyboard is at the appropriate height then you have to look down on the screen. If you regularly use a laptop or tablet, consider purchasing a separate monitor and/or keyboard to improve your setup.
