Why is standing good for you?
Sitting in a hunched forward position places a lot of pressure across your lower back. Your lumbar discs are subjected to 1.5 to 2 times the force they would be in a standing position. Also, a lot of people, when they are seated, tend to place their neck in a forward-leaning position with their chin protruding forward. When they stand up and place the monitor at eye level, they are less likely to do that. Standing in an upright position with your knees straight requires very little energy or muscle effort in your neck or back. Standing also uses more calories than sitting and your legs get some exercise, which is good for your overall health and fitness.
What is good standing and sitting posture?
The key is to efficiently use the muscles around your neck and back by sitting or standing in a position that doesn’t require a lot of muscle work to maintain that position. Good standing posture is symmetrical and well aligned. This leads to even weight bearing on both feet, leveling of the shoulders and pelvis, and holding up the head and neck.
In good sitting alignment, your hips and knees are level (or the hips are slightly above the knees), your spine can be vertical or slightly reclined, and the small arch in the lower back is maintained. Your shoulders should be relaxed down away from the ears, elbows by your side and bent to about 90 degrees, wrists are neutral (not bent up, down or away from each other), and your head is facing front without protruding forward.
What can someone do to make their home furniture more comfortable for working?
If you don’t have an office chair, recline back in your chair without slouching your lower back. Put a small pillow behind your lower back to maintain an arch. When you recline, you put your upper body weight into the chair instead of down your spine. This also relieves the neck muscles from having to hold your head up. Feel the back of your neck in that posture. If you lean forward, you will feel your neck muscles tense up. On the other hand, if you recline backward, those tense muscles will relax and help to decrease neck pain.
If your computer monitor doesn’t have an adjustable stand, there are now commercially available devices that allow you to raise or lower your monitor so that the screen is at eye level.
If you work primarily from a laptop or tablet device, what’s a good height to keep it so you avoid “tech neck”?
I would recommend that you recline in your chair and then look straight ahead. If you are using a laptop, you can raise it using books or a box, and you can buy a Bluetooth-enabled keyboard and mouse since a laptop keyboard is small and cramped. This allows you more options to find a position that is comfortable for your neck and hands.
In general, you should avoid holding your neck in any position for an extended period because no matter how good the position, if you hold any part of your body in one position for too long, it will strain that part of the body. We like to say that motion is lotion for your body.
What about working in bed lying on your side or back?
Lying down for long periods will lead to deconditioning. So while it is OK to work lying down, just don’t do it every day all day. Also, if you are lying down, be careful not to assume a slouched or forward head posture for a prolonged period. Any position that makes part of your body hurt is not a good position for you, so listen to your body.
“Good sitting and standing habits in general will help ensure that you apply the principles of ergonomics consistently,” says Dr. Evan Johnson. “Often we unconsciously slip into old, unhealthy movement habits, even if we know the ‘proper’ way to do something. Learning to apply good postural and movement habits consistently is a skill. Developing new skills takes practice.”
