90-minute chunks

Filed under: Just Stuff — theotheri @ 1:42 pm

About a month ago I read that doctors were recommending that people do not sit at their desks or computers for more than 90 minute stretches.  Apparently, blood tends to get blocked at the back of the knee when we are sitting, a situation that ultimately increases the chances of a stroke.

So I’ve been dividing my day into 90-minute chunks.  It’s had several surprising effects.  The first is that walking away from the computer screen seems to facilitate something in my brain.  Just walking away often unblocks a problem I’ve been working on or gives me a new idea.

But I’ve also been chunking in reverse.  When I’m doing something physical, I do it in 90-minute chunks and then take a break for a cup of coffee or lunch or sometimes just to check my email or review the news on-line.

What has surprised me is that I seem to have a lot more energy on a regime like this.  I don’t get tired as early in the day, and find myself with the stamina to add an extra task that in the past would have probably outfaced me.

I don’t claim this is a panacea.  I’m still recognizably older and slower than I was ten years ago.

But I’m faster than I was a month ago.




  1. thanks! well worth trying! certainly better than pills or seeing a shrink or running 10 km a day…..(at least for me)

  2. It really does work doesn’t it? Here’s a great post about 90-minute chunking, though the post’s about marketing this technique works
    with almost anything..

    • Thank you for sharing this elaboration of 90 minute chunks. I had no idea that the idea had made it into the marketing world. But I read your blog post, and think the advice is right on. Yes, I agree – it works with almost anything. Though sometimes I bend the rules a little and work with chunks “between 30 – 90 minutes.”
