None of these changes are actually what makes a difference. The difference is made by having a workplace where you are enabled to request/make these changes. It's a type of Hawthorne effect.<p><a href="https://en.wikipedia.org/wiki/Hawthorne_effect" rel="nofollow">https://en.wikipedia.org/wiki/Hawthorne_effect</a>
I have an adjustable desk at work so I put it in the standing position often.<p>Standing for hours really hurts your feet.<p>I don't find it surprising at all that people sit more at home if they have a standing desk.
I have one of those automatic sit stand desks. The Jarvis. Only for home though.<p>I <i>relish</i> my work from home days. They're glorious. I don't want every day to be a work from home day, but when it works out, I love it.<p>I don't even care about the health benefits. I just like standing sometimes, without having to stop working.
