As a fun experiment, I decided to use my Garmin heart rate strap to monitor my heart rate while I slept. Mainly, I just wanted to get a more-accurate read on what my resting heart rate might be. I originally thought it might be about 59, after taking some measurements. But, by using the heart rate monitor while sitting on the couch doing nothing, I thought it might be about 52. To get a longer read, I used the monitor while I slept through the night.
Below is about a 6-hour period from last night. I believe I can draw an imaginary "rolling" trend line in the lower/mid 50s, maybe around 53 or 54. It's also interesting to see the highs/lows of my heart rate, likely responding to various dream states, REM sleep, etc.
