Did you know that, statistically, nearly one third of all time taken off from work is due to injuries stemming from poor office ergonomics?
In fact, office work can actually affect your body in more damaging ways than many physically demanding tasks. After a long day at the office, have you ever felt a stiff neck, sore shoulders, or back pain? This is due to poor office ergonomics.
Office ergonomics research has shown that sitting for extended periods of time is actually doing harm to your spine, shoulders, back, and neck. Knowing this, it should come as no surprise that a majority of the discomfort you feel after a long work day is actually stemming from poor office ergonomics. Moreover, when your workspace isn’t designed with office ergonomic features in mind, bodily discomfort can be felt even stronger. Here is the complete guide to help you to understand the dangers of poor office ergonomics and to set up a healthy office ergonomic environment.
Ergonomics (from the Greek word ergon meaning work and nomoi meaning natural laws), is in essence the study of designing equipment, devices and processes that fit the human body. The two terms "human factors" and "ergonomics" are essentially synonymous. Ergonomics takes all human factors into consideration, including height, weight, sight, feel, etc.
Proper ergonomic design is necessary to prevent repetitive strain injuries and other musculoskeletal disorders, which can develop over time and can lead to long-term disability.
Ergonomic design is often factored into office products, hence the name office ergonomics. These products can include desks, chairs, keyboards, computer monitors, and everything else in between. One example of products designed with office ergonomics in mind is ViewSonic's Office Ergonomic Monitor collection which has been designed specifically for the purpose of providing office monitors that improve comfort at work and reduce work related injuries.
Ergonomically designing these types of products is particularly beneficial because a large number of people use them for extended periods of time every day. Using poorly designed or poorly positioned products in the office for extended periods of time can place unnecessary strain on the body.
WMSD’s account for over 40% of workers' compensation claims among office workers
Musculoskeletal injuries and vision problems are common injuries resulting from poor office ergonomics. Your workers can get injured when their bodies are required to adapt to tasks that overextends their body's physical limitations. According to the Washington State Office Ergonomic Research, the single largest class of injury claims in the office is Work-related Musculoskeletal Disorders (WMSD's). WMSD’s account for over 40% of workers' compensation claims among office workers. These injuries are costing State Fund employers over $12 million per year in medical and time loss costs and are responsible for over 70,000 lost work days per year.
Due to the nature and severity of WMSD's, they account for a lion share of injury costs - about 60% of total claim costs. WMSD's are prolonged injuries that may become worse over time and therefore become costlier when compared to sudden injuries such as a slip and fall. This also means that it can take a long time to get an employee back to work, resulting in even higher medical and time loss costs.
Technology has come a long way to improve our work lives and change the way we interact with others and our office environment. Nowadays, everything on your work desk, including your computer monitor, laptop, keyboard, etc. all plays an integral part in your work life.
While these helpful advancements in technology have definitely improved our work lives, they are also placing unnecessary strain on our bodies at the same time.
Some companies have started to adapt to today's working environment by making a shift to more dynamic work spaces, such as huddle spaces. As a result, however, people are beginning to develop unhealthy postures that are negatively impacting their health without them even knowing it!
Pain in the fingers, wrists, or other parts of the body. Pain can range from dull aching pain to sharp stabbing pain and even a burning sensation
Tingling or numbness, particularly in the hands or fingers
Swelling, inflammation, or joint stiffness
Loss of muscle function or weakness
Discomfort or pain in the shoulders, neck, or upper/lower back
Extremities turning white or feeling unusually cold
Muscle tightness, cramping, or discomfort
Clumsiness or loss of coordination
Range of motion loss
Discomfort when making certain movements
Improvements in the quality of work produced
Boosted morale among employees
A reduction in employee turnover
More focus and concentration at work
The first step in implementing office ergonomics is to analyze the work environment you will be aiming to improve. What type of work is done there? What is the physical landscape like? Analyzing where potential problems may lie and applying the appropriate office ergonomic procedures should be your goal during this phase.
In most cases only small changes will be needed to improve your office ergonomics. A company along with the help of employees together should be able to resolve most office ergonomics issues.
While unlikely, it is still possible that an entire office ergonomics overhaul will be needed. In this case, seeking professional consultation on how to improve your office ergonomics atmosphere may be a helpful resource.
Office work today involves a lot of time spent sitting. While it may seem harmless, this action day in and day out has the potential to damage our bodies. Unfortunately, most people won’t even realize this until they have already started to feel the effects of repetitive strain injury (RSI) stemming from a poor office ergonomic desk setup.
Easily overlooked mannerisms such as slouching and tensing your shoulders can be attributed as the root cause for more serious office related injuries such as pinched nerves, headaches, and wrist injuries.
As it's probably time to give your workspace an office ergonomics makeover, here are a few things you'll want to consider you're working to keep you comfortable and injury-free.
Here are some tips for you to set up your workspace and help to establish healthy office ergonomics
The computer screen is the center of your workstation. All of your attention is focused on it throughout the day. As it is the center of your workspace, improperly positioning your monitor can cause you to adjust your body in a damaging way as a result. Tilting your chin upwards or bending your head and upper body to accommodate for improper positioning is common when monitors aren’t positioned correctly.
This type of body positioning can become the sole culprit of why you are suddenly experiencing eyestrain, headaches, musculoskeletal injuries, and overall discomfort.
According to the Canadian Centre for Occupational Health and Safety, two factors must be considered when deciding how to rid yourself of postural discomfort resulting from the strain your body goes through to view your monitor.
Viewing angle refers to the degree above or below the imaginary horizontal line that starts at the viewer’s eyes and goes to the center of their computer screen. Poor viewing angles lead to postural (neck and shoulders) discomfort.
Viewing distance refers to the space between your eyes and your screen. Positioning your computer screen at an inappropriate distance contributes to eyestrain.
Existing recommendations for viewing angles and viewing distances differ from source to source. For this reason they should not be taken as hard set rules but rather as guidelines that can be used as a starting point for improving your current situation.
Research shows that when your body is at rest your eyes naturally assume a downward line of sight. The amount of downward gaze ranges from about 15-30 degrees. The full range of eye movement is 60 degrees; people engaged in visually demanding tasks limit their downward eye movements to about 30. Based on the experimental findings above, it is safe to assume that placing your monitor at around 15 degrees below your horizontal line of sight will result in comfortable positioning for your body and help to establish healthy office ergonomics. The reasoning behind this is that this positioning will act as the center point between the 30 degrees of eye movement used at work by covering 15 degrees above and below your natural line of sight.
Studies have also concluded that people doing intensive visual work indicated that looking upwards above the horizontal line of sight is tiring. Looking below the horizontal line of sight, however, is not. Based on this information you can consider moving your monitor downward by up to another 15 degrees when finding the positioning most comfortable for your specific office ergonomics setup.
Since not all people’s bodies are the same, working on a monitor with a wide range of height, swivel, and tilt flexibility, such as the ViewSonic VG2448, is essential for finding the most comfortable monitor positioning for you.
It’s common for people to tell children not to sit too close to the television – and they’re right! The reason for this is that eyestrain is caused by the muscular effort required to focus on objects at close distances. Looking at objects that are further away has little to no impact on eye strain. Deciding on a suitable distance for your monitor is up to personal preference and is subject to change over time.
Accommodation and convergence are the two main functions at work when viewing of objects at close distances. The shorter the viewing distance, the greater the muscular effort exerted for accommodation and convergence. An increase in accommodation and convergence effort results in increased strain on the eyes. A further viewing distance will diminish this muscular exertion but may make finer images and characters displayed on your computer screen more difficult to read. You’ll know when you’ve found the correct viewing distance for effective office ergonomics when you can easily read the screen without placing any strain on your eyes.
“Eyes have a default accommodation distance, called the Resting Point of Accommodation (RPA) and a default Resting Point of Vergence (RPV). With distances greater than the RPA and RPV there is no need for either accommodation or convergence.” Viewing a computer screen under these distances is not necessarily harmful to the average person, however, as long as recommended eye "rest breaks" are conducted.
“Measurements of an RPA around 75cm or 30” and an RPV around 80cm or 32” are close enough in value to make setting up the proper viewing distance for office ergonomics a simple process. A viewing range of 40cm – 70cm or 15” – 27” is a visually comfortable range for a majority of computer users. In situations where the recommended viewing distance is too great for the operator to see images clearly it is better to increase font size than to force a shorter viewing distance."
Although it may not seem important, the orientation of your mouse, keyboard, and monitor on your desk can affect how healthy your office ergonomics setup actually is. Your mouse and keyboard should be positioned closely together with your keyboard centered on your desk to provide the best ergonomic results.
For this to be done correctly, make sure the middle of your keyboard is directly aligned with the center of your body. The goal is to create the most natural positioning or your wrists when typing so as to not overexert any particular side of your body. As a general rule, it is best if your keyboard and mouse sit at a height where your elbows bent at or near 90 degrees so you aren't bending your wrists to type.
As long as you have both an adjustable seat and you a monitor that you can flexibly adjust , you should be able to easily adapt your desk setup correctly to your working environment.
The workstation graphic below provides a good idea of the proper seat height, keyboard height, and monitor height for healthy office ergonomics.
Ergonomic office chairs have been the topic of discussion for years. Chairs such as those made by Herman Miller Aeron are an example of a successful, yet expensive ergonomic solution. Though the Herman Miller Aeron is expensive, more affordable products can be easily found at many office supply shops.
Here are the things to consider when selecting the proper ergonomic office chair:
Last but not least, try to organize the items in your office by frequency of use. Place the items that you use most often within arm’s reach if possible. Items used less frequently can be kept further away to avoid cluttering your workspace and creating potential injury.
With these simple tips you’re now on your way to creating a healthy, comfortable office ergonomics setup. They may seem simple but they'll make a world of difference to your comfort in the office.
