Another end of day comparison fitbit 16,508 steps hband 13,760 steps. No idea which is closest to reality.
So I come to recharge both devices and they both report being about 70% charged. I am mystified by this, but whichever way the E500/hBand copes with more than 24 hours usage on one charge.
hBand has now reported sleep. It reports 6 hours 55 minutes, fitbit reports 6 hours. My sleep tends to be quite disrupted (particularly when I take menaquinone-7 - a form of k2 - which I did yesterday) and I take melatonin during the night to get myself back to sleep. For last night if anything fitbit overstated sleep. hBand clearly overreported sleep. I don’t think its analysis of sleep stages is as good as fitbit which is not perfect.
It does, however, correlate to reality in some way.
The glucose reporting is much the same with an unfed state of 4mmol/L dropping down as a result of exogenous melatonin to a minimum of 3.3.
The lower level of glucose whilst asleep may cause some difficulties with sleep maintenance, but probably assists with autophagy and the reversal of glycation where that can be done (the labile aldimine element of HbA1c is bidirectional and the ketoamine part is very slightly reversible, but not much). In any event if my glucose is not going over 7-8 mmol/L I have not got a lot to complain about.
I intend putting on a dexcom g7 today and have a blood test scheduled for 10.30am tomorrow so hopefully I will have a better idea of the absolute values.

A bit more on this. I went out to dinner with my children last night and came in quite drunk and then slept for about 30 mins on the sofa before going to bed. hBand/E500 picked up that I had fallen asleep although the software didn’t report on it that well. Fitbit took no notice. I find fitbit does not pick up short naps.
I have a Muse eeg which is very good at picking sleep periods, but it is a real nuisance keeping it in position on your head so I stopped using it perhaps over a year ago. However, if you want a home EEG it is quite good.
