Don’t Just Sit There—Move to Maintain Health




More than 90.000 new cancer cases a year in the United States may be attributed to physical inactivity and prolonged periods of sititng…Excess time in seat tied to some forms of cancer, other diseases…

     A conservative estimate, according to the study, which cites 49,000 cases of breast cancer and 43,000 cases of colon cancer.*

     The estimate comes from an examination of United States physical activity data and cancer incidence statistics. The health risks of inactivity are added to other health risks, known by just about anyone who is aware of health issues. These risks include heart disease, diabetes, and obesity.

     Another review of two hundred cancer studies worldwide (epidemiologist Christine Friedenreich of Alberta Health Services in Calgary, Canada) produced convincing evidence that regular physical activity reduces the risk of breast cancer, colon cancer, and endometrial cancer by 25-30 percent…and there is some evidence for a reduction of lung, prostate, and ovarian cancer.


     Count me as a person who leans toward a sedentary lifestyle. Not one of sitting on a couch indulging in chocolate covered cherries while pushing buttons on the remote control to change channels for soap operas, but as one who, as a writer, sits at the computer for hours, and as a reader adds many more hours of sitting. One thing I do do is alternate my time between these sitting activities and other motion activities. I also force myself to do exercises or walk several times a week.

     Still, I realize that this isn’t sufficient.


     Why does exercise reduce the risk of cancer in post-menopausal women? It appears to increase insulin sensitivity and reduce body fat, inflammation, metabolic hormones, and sex steroids hormones.


     I guess I shouldn’t just sit here. Doing what I want to do.

    I should get moving. I should do something I don’t want to do.

     It’s so difficult to change who I am.


Don’t just sit there, get well, study says, Greensburg Tribune-Review (from USA Today), November 7, 2011, B8
