Sitting Too Much Each Day May Result in Disability or Early Death



Hi Readers,

Everyone knows that sitting too much and being a couch potato is generally not good for health, right?  Well, the term, “couch potato” brings to mind an overweight, lazy person on the sofa eating fatty snacks and watching television.  However, scientists conducted a study and found that people who sit most of the day have an increased risk of developing heart disease, diabetes, cancer, and shortened lifespans.  Published in the peer-reviewed scholarly journal, Annals of Internal Medicine, researcher Aviroop Biswas and his research team reviewed 47 health studies [a meta-analysis] and found that people who sit most of the day are 24% more likely to die from these conditions compared to their counterparts who are more active during the day even when they exercise an hour or more daily! An hour of exercise daily does not mitigate all of that sitting. 

So what is “sitting too much?”  Biswas defined it as sitting from 8-12 hours daily.  That places a person at great risk and his team recommended that sitting should be limited to 4-5 hours maximum per day.  People who sit at a computer/desk all day and professional drivers may be at the greatest risk because their occupation requires sitting. The researchers found that sitting compresses vital organs and impacts metabolism negatively.  It may result in leg disorders from poor circulation, muscle degeneration, organ damage, spinal damage, soft bones, diabetes, and cancer.  What is a virtual professor to do?

The experts suggest reducing time spent sitting by watching television standing up, taking walks or walk around, and gradually reduce sedentary sitting time each day.  Currently, I wear a Jawbone UP that reminds me to get up and move every hour.  I may have to invest in one of those standing desks!
