Taking a Stand for Office Ergonomics


THE health studies that conclude that people should sit less, and get up and move around more, have always struck me as fitting into the “well, duh” category.
But a closer look at the accumulating research on sitting reveals something more intriguing, and disturbing: the health hazards of sitting for long stretches are significant even for people who are quite active when they’re not sitting down.
(..)
Suppose you stick to a five-times-a-week gym regimen, as I do, and have put in a lifetime of hard cardio exercise, and have a resting heart rate that’s a significant fraction below the norm. That doesn’t inoculate you, apparently, from the perils of sitting.
The research comes more from observing the health results of people’s behavior than from discovering the biological and genetic triggers that may be associated with extended sitting. Still, scientists have determined that after an hour or more of sitting, the production of enzymes that burn fat in the body declines by as much as 90 percent. Extended sitting, they add, slows the body’s metabolism of glucose and lowers the levels of good (HDL) cholesterol in the blood. Those are risk factors toward developing heart disease and Type 2 diabetes.
