This study says that standing for more than two hours increases risk of certain things like blood clots. It also says sitting for a whole shift is bad, and you should be moving every 30 minutes. This does not mean standing desks are useless; I’m not standing for my circulatory system, I’m standing for my back. I also don’t stand for an entire shift, that’s what’s great about the memory settings. I’ll switch back and forth depending on what I feel like doing. Sometimes I’ll have it on “sit” all day, other times I’m switching back and forth quite a bit. I don’t think they’re useless, nor do I think it’s some health miracle, but it does give me more flexibility and I don’t think I’d go without after having used one.

Time spent standing was not associated with CVD risk but was associated with higher orthostatic circulatory disease risk. Time spent sitting above 10 h/day was associated with both higher orthostatic circulatory disease and major CVD risk. The deleterious associations of overall stationary time were primarily driven by sitting. Collectively, our findings indicate increasing standing time as a prescription may not lower major CVD risk and may lead to higher orthostatic circulatory disease risk.
