I've read some stuff about the negative effects of sitting for prolonged periods of time. As a consequence, I've been experimenting with standing more at work when the task will permit it. I've been enjoying it. I think the next step to make that work even better would be to get a desk that can quickly raise or lower. (The glacial speed movements of some electric raise/lower desks would discourage much use.) Here are some resources I've found interesting.
- NY Times article is a good summary
- This piece from Exercise and Sport Science Reviews is co-sponsored by Steelcase, the furniture makers, so I must take it with a grain of salt, but it recommends standing as an activity that should be categorized as superior to sitting, whereas they have been both lumped together as "sedentary" in previous literature.
- An abstract with says standing or sitting on a therapy ball are about the same, and both more active than sitting in a chair.
- This survey of papers says the results aren't yet conclusive about the dangers of sitting too much.
