Sleep Targets: are they measured against a full 24-hour span or just your "nightly" session?

[slimbuttons]

Here's the key question: is the Sleep Target measured against how much you sleep, total, throughout a 24-hour day (i.e., night's sleep + naps)? Or just against a single sleeping session --which I assume would generally be your nightly sleep?

Longer version: My sleep schedule is to sleep X hours at night Y hours in the afternoon. The Y in the afternoon is important -- I conceive of it not as a "bonus" nap, but as part of my sleep for the day.

I can't figure out: does the Fitbit app, when considering if I've reached my Sleep Target, only count the X hours at night that I slept? (Which I guess it could know to was my main "night's sleep" because it is (a) at night, and (b) longest). Or does it include my total hours, X+Y, night's rest + afternoon nap, in figuring out if I've made my Sleep Target?

It includes all sleep time.  But when trying to analyze, note sleep is always credited to the day on which you wake up, and naps of less than one hour will probably not be detected (without some special doings).

Thank you for answering with such useful information, @JohnnyRow! One follow-up: are you aware of specific specific "special doings" to get those sub one-hour bursts counted? That'd be useful for the schedule I keep. (I know there's no detailed sleep data for stretches of less than 3 hours, etc.).

I appreciate the help!

Though not officially recommended by Fitbit, what I have found is you can get shorter naps counted by using the 'Begin Sleep Now' button, which really is intended for trackers without heart rate monitors to recognize sleep.

On phone app, click Sleep tile, then + (plus sign) at top right, then 'Begin Sleep Now'; when you wake up, click "I'm Awake" or some such message.  If you do have heart rate detecting model, this is best used only when you expect to nap less than one hour.

Thanks so much! That's actually _doubly_ helpful because I'd been doing
that for naps anyway, but had just decided not to (because the Charge 4 was
good at automatically registering them anyway). But it's good to know that
I should probably just keep doing this when I remember.

Really appreciate all the help.

If the nap is at least an hour, Fitbit should pick it up automatically by itself.

Got it; thank you!
