rem sleep higher since july 2025

My monthly average REM sleep figure has been consistently higher since July 2025.  I need to know if this is due to a change in my medication or a software upgrade.  I'm aware that an upgrade around this time reports increased wake time but can't find anything about REM sleep.  I have a Pixel 3 watch and Fitbit 4.58.

Hi @jimhar   Fitbit announced the algorithm change in early September.  I hope this information helps you sort things out.

Thanks, that's very helpful.  There were some reports that earlier in the year there was a change that made REM and light sleep shorter, which is fine because mine is longer.  I am planning to write up a medical case report so I need to be absolutely sure that the increase in REM sleep wasn't an artifact of a software change.
