Your sleep efficiency...What does that mean?

[SunsetRunner]

Okay...this may be a stupid question BUT I am gonna ask anyways. What does it mean when it says your sleep effeciency is 92%-im assuming its good but just not sure what it exactly means LOL. Does it mean I sleep 92% of the time im laying down?

sorry if its a stupid question- in my defence i have been sick all week 😞

You're correct.  It is the percent of time you were actually sleeping compared to how long you were in bed.  I would say 92% is good, I'm usually in the 30-40% range :(.

im not sure how accurate it is. I wake up for a few seconds many many times every night, to either turn or for whatever. But i will sleep back sometimes very quick, but someones 2-3 mins, would my efficiency still be over 85% so easily?

Restless counts as me waking up for those few seconds/minutes?

Most of the times I have an efficiency of 95%, so I guess I'm alright 😄

I don't know what the % means, because it doesn't take into account the length of time it took you to go to sleep, only what happens afterward. I will post mine as an example- even though it took me well over an hour to get to sleep, and I awoke many times, with a short overall duration, it said my efficiency was 73% for a very poor night's sleep. I was in bed for 6 hours, and slept only 3 of it- to me, that's 50% and not 73. I would say less than that, because I didn't get enough TIME in to really make it a good, restorative sleep at all.  It's a number I won't be relying on, because it's not very useful.

My fitbit has given me a sleep efficiency of 99 percent, and I always awaken totally drained, but then again I have low cortisol levels and a mild sleep apnea. That is probably why I feel tired all the time.

[tridogrob]

well, 15% of 8 hours is 72 minutes. so, tossing and turning for a couple minutes even 10 times would get you to 85%

Don't feel bad, I'm just getting started with my Fitbit and I don't even see where my sleep efficiency is reported. Where should I look?
