Blood Glucose and Cortisol levels when asleep.

I wonder if this is possible, for future versions of fitbit charge 5 watch.

Does anyone know if this is in the works?

Thanks,

@scottr99   A major competitor is working on non-invasive glucose monitoring, but it is probably years away.  This is a feature that requires FDA approval.  Fitbit is very hush hush about features that are in development.

As far as non-invasive cortisol levels are concerned, I'm not sure anyone is developing this.  There is a clear need for continuous non-invasive glucose measurement.  Cortisol levels have a circadian rhythm and elevated cortisol, reflecting stress, can affect sleep.  The need for continuous monitoring isn't clear cut.
