Tablets are modern conveniences that make our lives more mobile, productive, efficient, and fun. These magnificent pieces of technology have revolutionized how we entertain and educate ourselves, communicate with each other, and even how we do business. But, since these devices can be used in many different places and in many different ways, we often find ourselves in awkward, compromising, or ergonomically unfavorable conditions. Have you ever spent a prolonged amount of time on your iPad only to realize that you have somehow twisted yourself into a human pretzel trying to get comfortable? Isn’t it counterproductive to do your online browsing/shopping on your tablet if it makes you feel like you just finished playing a contact sport? You might as well be fighting for those sales, literally, throwing elbows and wrestling with other sales-hungry shoppers in a Black Friday stampede. But nobody wants that. So, read on to see how you should be using these tablets - safely -and to make sure that using these devices is beneficial, not a pain in the neck.
Posture and Position Matter
In January of 2012, Harvard School of Public Health released a study dedicated to the health ramifications directly related to the increasing use of tablet devices such as head, neck, and wrist pain. The study, headed by Jack Dennerlein, an adjunct Professor of Ergonomics and Safety at Harvard University, articulates the ways in which a person’s posture as well as the design of the tablet and its case, affect comfort and in turn, the health of users. Dennerlein says that the position in which we hold the device - as well as accessories used in conjunction with it- can impact our comfort greatly.
The Harvard Study observed tablet users as they used different mobile devices in the 4 most commonly used postures. Infrared sensors revealed any potential flexion or angles of the head and neck that could lead to injury or pain. Here are the four most common positions, as well as tips for improving your ergonomics while using a tablet:
Dennerlein’s study finds that tablet users experience much more profound head and neck flexion angles than traditional computer users and that the worst way to use your tablet is by placing it on your lap. Tablets are meant to make us more mobile and remove the body strain associated with traditional desktop computers and in order for that to work we must be aware of our posture. “With a tablet, you shouldn’t be sitting with [it] for long periods of time,” he says. “They’ve given us the freedom to move around again.” And moving around is Dennerlein’s first piece of advice for avoiding the pain of long term tablet use. A combination of the following tips should help to prevent this avoidable pain in the neck.
5 Tips To Prevent The Pain:
1. Re-Positioning is KeySitting too long in any one position is always an invitation to strain, as our bodies aren’t designed to be sedentary for long periods of time. Muscles and tendons need a break, and Dennerlein says to reposition yourself every few minutes. “If you’re feeling uncomfortable, listen to your body.”
2. Avoid The Lap Hand Position (As seen above in the upper left corner.)“You can get away with a tablet propped on crossed legs for maybe a couple minutes on the subway, but any longer- you just don’t want to.” So all those Apple commercials where we see iPad users relaxing on the couch with the device on their lap, surfing their tablet - yeah, don’t do that.
3. Get A StandStands, mounts, workstations, it doesn’t matter which you use, just as long as your tablet has a built-in stand that allows you to position the screen at multiple viewing angles. “The major finding of our study was that the case used with a device is what really matters,” Dennerlein said. “Different cases create different head angles for how people look at these devices, but a lot didn’t have what we call the “Goldilocks angle’ - somewhere in between that’s not too steep and not too shallow.” For best results, a case propped on your lap should be at 45 degrees; when sitting on a table or countertop, it should be more like 60 degrees. Dennerlein also noted that smaller, 7-inch tablets are much lighter and easier to hold and therefore cause less strain. Try to maintain neutral wrist posture and alternate hands when holding devices. Consider a case with hand straps to reduce the amount of time spent gripping these devices. (Would like to link to a few of our products here if possible.)
4. Avoid Touch-Screen TypingWhile some companies are coming out with amazing mobile devices specifically designed for content creation, most models are engineered for consumption. While there may be a touch screen keyboard on your tablet, that doesn’t mean that using it is a good idea. Besides the fact that it is much more difficult to type on a tablet than a physical keyboard, touch screens are almost always propped at angles that destroy wrists and can lead to carpal tunnel syndrome. Dennerlein suggests that if you are going to be typing a lot on your tablet, get an external keyboard. If scrolling makes your wrist feel like it's on fire, try using a stylus pen to navigate your touch screen.
5. Beware The Glare!Dennerlein says that the highly reflective glossy display of mobile devices is one of the biggest factors that determine how we position ourselves when using them. As such, we reposition ourselves in order to “fix” our view. Anti-glare screen protectors are available and can reduce your discomfort while you tablet surf.
We hope that these tips stick with you, and the next time you find yourself twisted up with your device like a circus contortionist, you'll know to use the appropriate accessories and to self-correct your posture, preventing your tablet from being a pain in your neck.
