Good ergonomics increase typing speed by achieving a more efficient positioning for typing movements that requires less motion to reach each key. Considering that the average person spends about 8 hours a day in front of a computer, making a few adjustments to a computer desk setup can have a huge impact on both physical comfort and typing speed. One of the most common injuries caused by improper ergonomics is Carpal Tunnel Syndrome. Carpal Tunnel Syndrome occurs when compression at the wrist causes pressure on the median nerve. This can result in tingling, pricking, numbness, pain in the hands or wrists, and loss of grip strength.
In some cases, the pain can even travel up the arm and into the shoulder. Treatments involve everything from splints to expensive surgery, and this is only one of the likely injuries to occur from poor posture and ergonomics. For a person who tends to slouch or lean towards the monitor, back and neck injuries are another concern. The easiest way to avoid these injuries is to design your workspace to be as ergonomic as possible and take regular breaks as you work to avoid repetitive movements. The best place to start is with the desk chair. The height should be adjusted so that a user’s arms are bent at a 90° angle or greater when sitting at the desk with both hands on the keyboard. Feet should be flat on the ground, or on a foot stool, with thighs parallel to the floor. This not only helps with back support, but stability as well. Allowing about 3 inches between the back of the knees and the front edge of the chair seat is ideal to help maintain proper circulation in the legs.A foot stool is very helpful when the feet don’t quite reach the ground.
It also helps lift the thighs slightly for better circulation and automatically tilts the body slightly away from the computer. Adjust the armrests so the lower arms rest parallel to the floor. It’s best that armrests only be used when not typing, to help maintain proper body alignment. The monitor should be adjusted so that the top of the screen is slightly below eye level. This results in a slight bend in the neck, which reduces the neck strain that can occur when a monitor is lower or higher. Position the monitor to avoid glare by placing it at a right angle to any light sources or windows and make sure there is at least a 20-inch distance between the computer screen and the user to avoid eye strain. The keyboard should be placed slightly below the elbow and at a negative angle. This allow the wrists to remain straight while typing. Avoid using a wrist rest or armrest while actively typing as this can cause the wrists to bend, placing unnecessary strain on them. Keeping elbows close to the body can help with typing speed since it puts the arms in the most efficient position for reaching the keyboard.
One of the most important aspects of desk ergonomics is posture. Even with a perfect ergonomic setup, poor posture can result in a loss of the ergonomic benefits. The main thing to remember is to not slouch.Sit up straight, with the back placed at a 90 degree angle to the legs. Leaning back rather than towards the screen is very important to help avoid slouching. Slouching and leaning forward in the chair both contribute to both back and neck strain. Finally, take breaks and stretch. The 20/20 rule is a good rule to follow: take a 20 second break for every 20 minutes spent working on a computer. A few shoulder rolls, hugging yourself tightly, or even standing up and touching your toes can help loosen muscles and get those eyes away from the monitor. With these simple desk ergonomic adjustments, one can keep the body in proper alignment and avoid unnecessary strain. The added bonus is that perfect posture can significantly increase typing speed and efficiency.I’ll confess up front: I have terrible posture.
It’s been bad since I was in high school at least, and probably for even longer than that. It’s one of those things I keep in the back of my mind as something I know I should do, but never get around to, like eating more vegetables and sending more postcards. It’s really interesting to explore commonly held assumptions for Buffer blog, because I often find out surprising things. Researching how our posture affects us was no different. If you’re like me and struggle to sit up straight when you know you should, you might like this post. We’ve talked extensively about body language before. But this time, we wanted to take a different drift. The way we stand, sit, and walk actually has more long-reaching implications on our mood and happiness than we thought. The latest studies reveal it: Body language is closely related to posture—the way we move our bodies affects how others see us as well as our own moods and habits. In terms of scientific research, the two overlap quite a bit.
This isn’t too surprising, but how our posture and body language affect our thoughts is. For instance, a study at Ohio State University in 2003 found that our opinions can be subsconsciously influenced by our physical behavior. Here are two fascinating examples: When participants in the study nodded in agreement or shook their heads to signal disagreement, these actions affected their opinions The same study also showed that when participants hugged themselves, they were sometimes able to reduce their physical pain. Dutch behavioral scientist Erik Peper has done extensive research into this area as well. He regularly makes participants in his classes stand up and stretch for similar reasons why exercise has been linked to happiness, like here: Here are three fascinating things that happened once our posture changes: For example, when we sit up straight, we are more likely to remember positive memories or think of something positive in general, according to this experiment.
Another insight was that if we skip during breaks, we can significantly increase our energy levels. A slow, slumped walk on the other hand, can do the exact opposite and drain us of our energy. those who were most affected by depression before the study found their energy drained more than others. So Erik Peper is convinced (and I am, too) that we should keep a careful eye on our posture and body language—lest it bring us down without us realizing. When we talk more broadly of body language, as opposed to good posture, we can actually see the affects it has on relationships right throughout the animal kingdom. In particular, body language is used to express power through expansive postures (i.e., spreading out your limbs and opening up your body) and large body size (or the simple perception of large body size). You might know about Amy Cuddy’s famous Ted Talk and her incredible insights on how posture changes our hormone levels. Well, some more recent studies took this even further:
A study by researchers from Columbia and Harvard Universities showed that body language symbolizing power can actually affect our decision-making subconsciously. The researchers measured the appetite for risk of participants in either expansive, powerful poses or constricted poses (occupying minimal space, keeping limbs close to the body). Those in the powerful poses not only felt more powerful and in control, but were 45% more likely to take a risky bet. Plus, the study used saliva samples to prove that expansive postures actually altered the participants’ hormone levels—decreasing cortisol (C) and increasing testosterone (T): This neuroendocrine profile of High T and Low C has been consistently linked to such outcomes as disease resistance and leadership abilities. So clearly, our posture has more to do with our minds than we might have thought. And, in fact, it seems like our bodies come first: When we alter our posture and body language, it subconsciously influences our thinking and decision-making.
So if you want to take advantage of these proven benefits to live a healthier and happier life, where should you start? We know there are many parts of the body that can be painful when we have bad posture. Here’s just a short list of them: Unfortunately there’s not a whole lot of research into how exactly to adopt good posture—a lot of what we know tends to come from being told to "sit up straight" as children. A study in 1999, however, found that sitting at an angle of 110 to 130 degrees is optimal for spine comfort, and another in 2007 showed that leaning back at 135 degrees is ideal for preventing back strain. Not only is a position like this difficult to measure and maintain (do you know precisely what angle you’re sitting at right now?), not everyone agrees. The team at LUMOback has created a posture sensor that you can wear around your waist during the day to help you develop better posture. The device watches for slouching and shifting to the side and vibrates to remind you to sit up straight.
The team, which includes a doctor and a data scientist (as well as a medical adviser), doesn’t advise the leaning-back position for your workday. Instead, they maintain firstly that "the best posture is always the next posture," or in other words, always keep moving: We know that many of us have jobs that do require us to spend time working at desks, so knowing how to sit and stand with good posture is certainly important and beneficial to one’s health and well-being. That said, the human body was built to move, not spend eight hours at a computer. While many of the apps and devices designed to track our daily activity focus on workouts and regular exercise routines, LUMOback is more focused on small, regular bursts of movement: Walking around helps your body to reset itself into healthy posture, so make a point to get up from your desk at least twice an hour. When it actually comes to posture, the LUMOback team recommends a neutral pelvic postion (i.e., sitting up straight).
They promote this posture particularly for times when we’re sedentary for long periods, like sitting at our desks all day: When you maintain a neutral pelvic position with a straight and upright back, the vertebrae in your back are nicely aligned. This takes a lot of pressure off of your spine and back muscles, which can reduce back pain. Here’s an image from the study that promotes leaning back at 135º: As the LUMOback team points out, while this is beneficial for your lower back (if you manage to keep it straight), your upper back and neck will suffer if you try to maintain this position while working. In an office setting, you’re likely to have to crane your neck to see your computer screen and strain your upper back and shoulders to reach a keyboard. Thus, any potential lower-back benefits of a reclined position are outweighed by the negative impacts on your upper back and neck. For now, I’m going to give sitting up straight a go. If nothing else, at least I know it will probably put me in a good mood!
