Lowest Recorded Heart Rate per Night for last Six Months

Below is an Excel chart of my lowest recorded heart rate (BPM) every night for the last six months. Click on the chart to view in full size.

There is not a huge amount to say about it except that my lowest heart rate each night has been below 50bpm much more often since the middle of February 2021 than it was in the months before. There do appear to be macro cycles in play with the highs getting higher over the course of weeks and then falling down over the same time scale.
