I attended a seminar last Friday where Professor David Dunstan from Melbourne’s Baker IDI Heart & Diabetes Institute reinforced the negative impact that prolonged sitting is having on our health and wellbeing. Their statistics show that the average Australian adult now spends over 9 hours a day in “sedentary” activity – which means sitting! The disturbing aspect of their findings is that if you do the current recommended 30 minutes of moderate to vigorous activity per day, but still sit for prolonged periods then you are still at an increased risk of a host of conditions such as Diabetes, Cardiovascular diseases, breast and colon cancer and kidney disease, let alone the musculoskeletal aches and pains that will also ensue. This is because sitting induces “Muscular Inactivity” resulting in reduced blood flow and glucose uptake.
The solution they recommend is frequently breaking up your sitting. At work do this by getting up and moving at least every 20-30 minutes and at home go for a quick walk around the house during an ad break if you are watching TV or on a computer.
More about this next week.
