Where are you right now? Lounging on a recliner with the newspaper and coffee? Sitting on a kitchen chair taking in the news online? Well, you might want to stand up for this news. Your chair is slowly killing you.
Chair disease, as some call it, is an increasingly common malady that is almost always caused by spending too much time parked on your rear end.
It’s not really the chair’s fault, though. The problem is that most of us sit wrong – slouched forward with our earlobes in front of our shoulders – and for hours without moving. The result? Avoidable chair-related ailments, including flabby butts, an increased risk of blood clots, and back pain, the leading cause of disability in Americans younger than 45. Back pain affects 8 out of 10 people at some point during their life, according to the National Institutes of Health.
“Sitting all day is the worst thing in the world you can do for your back,” said Dr. Joel Press, director of the Spine & Sports Institute at the Rehabilitation Institute of Chicago.
Sitting puts nearly twice the stress on the spine as standing; slouching while you sit increases the pressure.
That’s because hunching forward pushes the back into a convex or C shape. Try it: Pull your shoulders back and together and put your hand on your lower back. That natural concave curve is what you want; slouching fatigues and overstretches the ligaments, causing back pain.
To make matters worse, we stay in this bad C position for hours, barely moving. Movement is key because the disks in our vertebrae are important shock absorbers. When we’re locked in one position, we’re starving the disks of nutrients.
Sitting also tightens and shortens the psoas – the strong hip flexor – which can affect how the pelvis rotates and increase the load on the low back. The gluteal muscles stretch out, but they’re not being used so they turn off and get flabbier from sitting.
A significant portion of low back pain can be remedied by avoiding the two most common sitting mistakes: leaning forward and having the chair too low. But to really stand up to chair disease, try the following:
Change your position. It’s the single best thing you can do, said Press. Stand up every 15 to 30 minutes and clasp your hands behind your back. Use the phone standing or simply straighten up, contract your abs and lean back.
Squat. It’s more comfortable than sitting because most of the weight of the abdomen is supported on the thighs, said Dr. William Meller, author of “Evolution Rx” (Perigee, $24.95). “Also squatting with the head and shoulders held up and back keeps the low back in its natural position,” he told me.
Use a lumbar roll. About 6 inches in diameter, lumbar rolls help maintain the natural curve of the back. You can use them in a car or the office. Order one – along with Angela Kneale’s useful handbook “Desk Pilates” – at optp.com.
Practice Robin McKenzie’s “slouch-overcorrect” exercise. If you have to sit for a long time, move from slouched position to upright 10 to 15 times, three times a day. (If you know yoga, it’s similar to moving between a seated cat and cow pose.) For more info: mckenziemdt.org.
Try the Alexander Technique. Studies have shown that the postural educational system is an effective treatment for back pain when used in conjunction with exercise. See alexandertechnique.com.
