The Dangers of Sitting Too Much
- by admin
This may work in some work environments ~ realistically, according to the Alliance for Natural Health, periodically taking time out from your computer, desk, television, and driving time to walk, move around, stretch, and flex your muscles, are all associated with a smaller waist circumference, lower body mass index, and lower blood lipid levels, and better glucose metabolism.
What about moderate or even vigorous exercise? Would that make a difference? According to a study of 4,757 adults by the European Health Journal, prolonged sedentary periods led to larger waist sizes and higher levels of blood fats, even if subjects participated in regular sessions of moderate to rigorous exercise outside of their inactive hours. So who fared the best? Those who did both regular exercise and took breaks to stand or walk at regular intervals.
According to ANH-USA, animal studies show that how much time we are sedentary is related to how well our bodies process fats. The studies in rats show that leg muscles only produce the lipase lipoprotein (fat-processing) molecule when they are being actively flexed ~ that is, when standing, or better still, walking around ~ and low levels of he molecule are associated with health problems, including heart disease. In short, sitting makes this important molecule slow down. In fact, actively contracting the muscles produces a whole suite of substances that have a beneficial effect on how the body uses and stores sugars and fats.
So maybe it is time to stick to those new year’s resolutions as well as adding some new ones. The daily decisions we make, including not sitting so much, can truly impact the state of our health and well-being. One of the interesting facts I learned from ANH-USA was that we even have specialized muscles designed for low-intensity activity ~muscles very rich in enzymes which grabs fat and cholesterol from the blood, burning the fat into energy while shifting the cholesterol from LDL (the bad kind) to HDL (the healthy kind). But when we are sedentary, our muscles relax, dropping that enzyme activity by 90% to 95% ~ the fat is left in the bloodstream and our healthy cholesterol soon dives by 20%!
How about you? Does your job keep you glued to your desk? If so, consider a few spurts of activity each hour. And perhaps all that sitting watching those favorite TV shows should take a back seat as well!
