From smart phones to computers to iPads, our beloved electronic devices are crippling our posture and contributing to weight gain, back pain, and joint problems like carpal tunnel syndrome.Fortunately, there are a few strategies and exercises – such as changing your position often and “reorganizing” your torso – that can address a lot of these potential problems and help keep you more fit and properly aligned.As miserable as back pain is, that may be the least of your worries if you spend a significant portion of your time on your duff. Sitting may actually cut years off your life. Lack of exercise is sitting’s evil accomplice. The more you sit, the less your body wants to move.According to a study in the British Medical Journal,1 reducing the average time you spend sitting to less than three hours per day could increase your life expectancy by two years, which is a significant decrease from the 4.5 to 5 hours per day the average American now spends on a chair or sofa.An analysis of 18 studies showed that people who sat for the longest periods of time were twice as likely to have diabetes or heart disease, compared to those who sat the least.2 Sitting has actually joined smoking and obesity as an important risk factor for chronic disease.
