Specific Nap Question

[MickeyMc]

My average time asleep is 6.5 hours, and my average sleep score is 70.  If everything stays the same but I add an hour-long nap during each day, will my sleep score actually be better than 70?  I ask this knowing that naps are not always recorded or added in and rarely (if ever) change a sleep score on the screen.  But my question is this: can I be confident that a nap never hurts, never would lower the sleep score if it was or could be integrated into the original night-time score?

I believe sleep score will be based  only on your long sleep session.  The only way a nap might change that would be if that might affect your sleep quality, say perhaps if you got some REM time in the nap so your body decided you didn't need as much REM at night, or maybe just the opposite, but you get the idea what I'm saying.

As for detecting naps, supposedly the cutoff is at least one hour for a nap to be detected, and at least 3 hours to get sleep stages and sleep score.  If you want to get credit for nap time less than an hour, however, there is a way: tap the sleep tile, then + sign at top right, then Begin Sleep Now, then when wake up, something like "Awake now" and it will log the nap based just on your stillness, not on heart rate, and you will never get sleep stages but you would not for that short time anyway.

Thanks JohnnyRow for your response.  Your first paragraph seems to answer my question with "No.  Taking a nap does not necessarily mean that your sleep score would improve:  it could, in fact, be lowered."  Your second sentence seems to referring to the next night's sleep. But as far as what I can tell, a nap is always added to the sleep that came before the nap:  it is never added to and does not directly affect the sleep (and score) which comes after it.  (Of course, a nap could affect the next night's sleep score, just because you might not sleep as soundly, but that seems a different matter.)

And thanks for the second paragraph about detecting naps which explains that part well.

Not sure if this directly affects what you are saying, but sleep is always credited to the day you wake up, so I suppose generally yes it is added to the night before, though you might be able to concoct a case where that was not the case, especially for night shift workers where is gets complicated.
