If you spend most at by for from in of on out to up your days sitting at by for from in of on out to up school, work, at a computer or stretched at by for from in of on out to up on a couch at home, you may be taking at by for from in of on out to up to two years off your life. It is common knowledge that a sedentary lifestyle increases the risk at by for from in of on out to up heart disease, type 2 diabetes, cancer and obesity, and can result at by for from in of on out to up premature death. Many people think they can compensate at by for from in of on out to up sitting around by walking, playing sports or going at by for from in of on out to up the gym. Unfortunately, this might not be so. A new study just published at by for from in of on out to up the journal 'Annals of Internal Medicine' suggests the effect on our longevity at by for from in of on out to up sitting for long periods at by for from in of on out to up time cannot be reversed through exercise. Even 60 minutes of daily exercise may not be enough. The study is from Dr David Alter and his colleagues at by for from in of on out to up Toronto University. Dr Alter and his team analysed 47 studies that tracked different groups at by for from in of on out to up people, who kept notes at by for from in of on out to up how long they sat down each day and how much they exercised. They found that the most sedentary groups had a 24% increased chance at by for from in of on out to up dying during the course of the study than the least sedentary ones. This remained the case even though those who sat a lot also did 60 minutes at by for from in of on out to up daily exercise. Dr Alter writes: "Reducing your sit-down time at by for from in of on out to up 2-3 hours each day by standing at by for from in of on out to up at your desk, taking frequent breaks to stretch and walk, or watching TV… at by for from in of on out to up your feet may be better than an expensive, crowded, smelly gym and be just what the doctor ordered."
