Best Sitting Posture Is Not Straight Up 291
An anonymous reader writes, "Researchers at Woodend Hospital in Aberdeen, Scotland used a new form of magnetic resonance imaging to collect images from 22 healthy volunteers, who assumed three different sitting positions: slouching posture in which the body is hunched forward, an upright 90-degree sitting position, and a relaxed position where the subject reclined backward 135 degrees. They concluded that the reclined position is the best, and the forward slouch the worst." From the article: "'We were not created to sit down for long hours, but somehow modern life requires the vast majority of the global population to work in a seated position,' Dr. Bashir said. 'This made our search for the optimal sitting position all the more important.'"

Apparently someone at my work must have developed some sort of carpal tunnel or something because in the 6 years I've been here this was the first time I was ever asked about how I liked my desk or chair. Anyway I don't actually sit in my chair, I tend to curl up into it, and essentially I sit on one leg at a time and lean to the left or right depending on which leg is under me. I also am a big fan of occasionally placing both feet up on the APC under the desk and leaning from side to side.
In addition to this I don't stay in any one position very long, but rather am constantly shifting or moving from time to time. The lady interviewing me told me that this was actually good and that only people who confine themselves to one given position for a very long time (read entire work day) are the ones who generally have trouble or develop problems with their joints.

What you want to do is spread your weight over as large a surface area as possible in order to minimize the strain on any one part, which means a chair that leans backward you're resting against. These latest suggestions seems similar to the "Zero Gravity" chairs that claim they're based on NASA research on reducing pressure on the spine (I'd love to find a real citation for that rather than just sales copy). I purchased a cheap recliner based on that type of design from General Superstore [generalsuperstore.com] that I've been happy with. At the office, I just lean my chair back; after a full day of working my back and hips feel dramatically better in that position than they ever did when I was sitting up straight.
While I'm babbling on this topic, I'd also suggest those trying to improve their back health look at the recommendations from Dr. Bookspan [drbookspan.com] I've become a real fan of some of the exercises she recommends there, and much of the most useful information from her is free on the web site.

- Avoid sitting. Stand up and walk around every half hour. More often if possible.
- When you are sitting, try to lean back like TFA says.
- Every night, before you go to bed, decompress your lower spine: lie on your back and put a few books (about 4-5 inches high) beneath your coccyx. NOT the small of you back - I'm talking about the top of your butt-crack: there is a flat area of bone there, put the pile of books there and lie out flat with your arms over your head for a few minutes. If it hurts - then it's doing some good. If you feel a "crack" then even better: that's some tension coming out.
- Turn over and do the "cobra" position. Plant your hands on the floor and jam your hips down to the ground so that your spine bends backwards in a massive curve. Keep this position (and keep your head and neck up straight) for a few minutes at a time.
- If you're not fit, consider also doing some stomach curls (Google 'em) and lower back strengthening routines. The better your musculature is around there, the better those muscles can support your spine and prevent injury by sudden movement. Movement which, if your lower spine is compressed by lots of sitting, will be more damaging.
There is it. Your 5-mins per day spinal insurance policy.
