Well I had a bug over Christmas. My resting HR was 10 bpm above my normal for some time. Actually it’s start to return to normal preceded my feeling a bit better which was interesting.
Interesting but I wonder how chronic illness like ours skew the data with permanently high resting heart rates. Probably taken off as outliers, but then that could be a treasure trove of data by itself.
Twice now HRV has indicated something was brewing when to all intents & purposes I seemed ok, both subjectively and on other stats. About two days after, symptoms developed. First case flu, second shingles.
