PSD Video Tip #38: Circadian Rhythm – Why You Should Learn More About It?

simple todo list

I got the topic for today’s video from Bill Nickerson. In his e-mail he mentioned about circadian rhythms and why they are very important to your productivity.

For instance, you might notice that you are very productive after waking, up whereas in the afternoon, you can barely keep yourself awake. This is circadian rhythm in action.

Check out the video for more information about this topic and also, check out Bill’s post on this topic on his blog.

  • Transcript: [spoiler]Hello, this is Timo from, and today I wanted to
    share a tip that I got from Bill Nickerson by e-mail. Bill mentioned about
    circadian rhythms and why it’s very important to learn more about it.Well, basically, a circadian rhythm is a natural pattern that we follow on
    a daily basis, and a circadian rhythm dictates when we are alert or when we
    are feeling tired. When you know this information, when you are alert or
    when you are feeling tired, it much easier for you to plan your day, for
    example, the night before.

    So, what I want you to do is that you should be aware of your alertness or
    tiredness, when you are feeling tired, when you are feeling alert. For
    example, you could have a log where you are recording those times when you
    are feeling good and when you are energized, then on the other hand, when
    you are feeling tired.

    When you have gathered this type of information, it’s much easier for you
    to see a pattern, and it’s also much easier for you to understand when you
    should be doing a certain type of work. So, for example, if you need to
    have one hundred percent focus on certain tasks, you should be doing that
    during your peak times. Whereas, when you are feeling tired, you might just
    take a nap or focus on some less valuable things on your list.

    Anyway, that’s basically what circadian rhythm is all about, and what I
    want to do is that you also go to Bill’s site and check out his post on
    this topic. I have also included some other resources on this very same
    subject. So, please share this video on Facebook, on Twitter, on different
    social bookmarking sites. Check out those resources under this video, and I
    will talk to you soon. Bye-bye.[/spoiler]

  • Great synopsis of the topic Timo.

    And in addition to the great post by me 8=) I really like the heatmap resource you’ve linked to by Charlie. It looks like he has some great stuff to start looking through. His concept of productive capacity vs productivity is certainly worth learning about.

    Thanks Timo. You do a great job with these videos. Someday I’m going to have to start doing video too.

      Thank you Bill for your contribution :)

      I’ll definitely want to learn more about the circadian rhythms. In fact, I just started reading about The Power of Full Engagement, which I think talks about this topic.


  • Hey Timo

    Thank you for sharing. Some food for thought.

    I’m a stay at home dad. I look after my 2 year-old daughter during the day whilst my son is at nursery 4 days a week and I have them both 1 day a week.

    It can be a bit of a juggling act to get anything done and feeling tired can be a real issue in my productivity.

    I’ll have a go at recording when I feel tired during the course of next week so I can see if I can change things around a bit.

      Hi Tim!

      Sure, let me know how things turned out after some recording – were you able to detect any daily patterns?


  • Tom


    Thanks for the synopsis. A self-educated understanding of your circadian rhythms is invaluable.

    • Timo Kiander

      Thank you Tom!

      Nice to hear you liked to video :)


  • very interesting
    playing with ones biological clock sounds like a good idea

      Hi Farouk!

      Yes, it helps to plan your day when you know your internal rhythm.
