About two months ago, I switched to using a standing desk at my day job. I had read about the dangers of sitting for long periods of time. It's bad for your neck, shoulder, and back. It poses health risks that can shorten your life. On and on. Having spent my whole life sitting, first in school and then in the workplace, I wanted to make a change. After all, I'm not getting any younger.
My first week with a standing desk took some getting used to. Part of it was logistical because I was still trying to figure out how to get to everything on my desk that I need. My feet or knees would also get sore from standing all day. Eventually, I resolved both issues. When I start to get tired from standing, I take a walk to get a drink or to use the restroom. I'm often forced to walk anyway to go to a meeting (where I wind up sitting for half an hour or an hour anyway). Yes, exercising can make you less tired. Something about stretching your muscles and loosening your joints, I'm sure.
Two months in, I really like standing while I'm working. Not only is it supposed to be better for my health, but it's supposed to help me think. I've also lost a couple of pounds that I can attribute to standing! If you haven't tried it before, spend a few minutes each day standing up while working. You don't need a fancy standing desk. When I'm at home, I stand up with my laptop on the kitchen counter or some other surface that's at a good height. Once you start standing, you'll wonder why you've been sitting for all these years.
