Biorhythms Background

I was inspired to try this experiment after reading this personal productivity article. For the most part, there was nothing new for me in this article, but I was intrigued by the section on tracking your biorhythms. I decided to basically try his experiment almost exactly — same frequency, same time period, same dimensions (i.e. Energy, Focus, Mood). The only difference is that I chose a five point scale rather than three. (I noticed he was using decimal points, which to me defeats the benefits of using a three point scale.)

A few things I’ve noticed after a few days of tracking:

  • It’s challenging to answer these questions consistently. What’s the difference between Energy and Focus?
  • My mood doesn’t really fluctuate based on time of day.
  • I’m not noticing any cycles, and I’m not sure that any of these dimensions are strongly correlated to time of day (other than I have more energy in the beginning of the day than the end). All three dimensions also seem related to type of activity (e.g. exercise, meetings, writing, eating, etc.).
