Beware, couch potatoes: The evidence is piling up that too much sitting can take a serious toll on your health.
A new study links sitting for prolonged periods of time to increased risk for heart disease, diabetes, cancer and early death -- even in people who get regular exercise.
"Even if you do a half an hour or an hour or of exercise every day doesn't give us the reassurance that sitting for the other 23 hours is ok. In fact, it's not," said Dr. David Alter of the Toronto Rehabilitation Institute, one of the authors of the study.
The study, published Monday in Annals of Internal Medicine, is based on a review and analysis of previous research. It found that the health hazards seem to be greatest for people who sit 8 or 9 hours a day. The impact was even more pronounced in people who did not exercise regularly.
The study found sitting for prolonged periods raised the risk of cardiovascular disease by 14 percent, cancer by 13 percent, and diabetes by a whopping 91 percent. Those who sat for long stretches and got no regular exercise had a 40 percent higher risk of early death. With regular exercise, the risk was smaller but still significant: about 10 percent.

Data Synthesis: Forty-seven articles met our eligibility criteria. Meta-analyses were performed on outcomes for cardiovascular disease and diabetes (14 studies), cancer (14 studies), and all-cause mortality (13 studies). Prospective cohort designs were used in all but 3 studies; sedentary times were quantified using self-report in all but 1 study. Significant hazard ratio (HR) associations were found with all-cause mortality (HR, 1.240 [95% CI, 1.090 to 1.410]), cardiovascular disease mortality (HR, 1.179 [CI, 1.106 to 1.257]), cardiovascular disease incidence (HR, 1.143 [CI, 1.002 to 1.729]), cancer mortality (HR, 1.173 [CI, 1.108 to 1.242]), cancer incidence (HR, 1.130 [CI, 1.053 to 1.213]), and type 2 diabetes incidence (HR, 1.910 [CI, 1.642 to 2.222]). Hazard ratios associated with sedentary time and outcomes were generally more pronounced at lower levels of physical activity than at higher levels.
Limitation: There was marked heterogeneity in research designs and the assessment of sedentary time and physical activity.
Conclusion: Prolonged sedentary time was independently associated with deleterious health outcomes regardless of physical activity.-------------------------------------------------------------------------------------------------------------------------------
I guess this means for me, that I will sit at the computer less. Perhaps I will rearrange it, so I got to stand and use it. The CBS short clip shows the lady standing...but, I sit to damn much..and that is the truth.
= new reply since forum marked as read
I think that it is the continuous sitting without a break that is so harmful. So after a 2 hour movie, we go for a walk and try not to sit down for a while. There is no extra charge to get up for a while. From what I have read, the human body was meant to walk around often, and not to sit down all day. I don't know, I am just as addicted to this thing that I am typing on as the next one. We need to do the best we can to improve some, and that is it...
