I tried to use a standing desk while coding, but I also had a hard time concentrating, so I stopped. However, according to Dr. Joan Vernikos [1] (former Director of Life Sciences at NASA, and author of Sitting Kills, Moving Heals [2]), neither sitting or standing for extended periods is healthy. It's all about movement and gravity. For a detailed explanation of why this is, and the research that backs it up, check out this interview between her and Dr. Mercola [3], it's really interesting. They talk specifically about standing desks at this time marker [4].
