→Your Office Chair Is Killing You

Frequent TV and Web surfers sitters have higher rates of hypertension, obesity, high blood triglycerides, low HDL cholesterol, and high blood sugar, regardless of weight. Lean people, on average, stand for two hours longer than their counterparts.

The chair youre sitting in now is likely contributing to the problem. “Short of sitting on a spike, you cant do much worse than a standard office chair,” says Galen Cranz, a professor at the University of California at Berkeley. She explains that the spine wasnt meant to stay for long periods in a seated position. Generally speaking, the slight S shape of the spine serves us well. “If you think about a heavy weight on a C or S, which is going to collapse more easily? The C,” she says. But when you sit, the lower lumbar curve collapses, turning the spines natural S-shape into a C, hampering the abdominal and back musculature that support the body. The body is left to slouch, and the lateral and oblique muscles grow weak and unable to support it.
