It's hard to read the numbers in that, but I don't see anything that stands out as being odd. Is there something in particular that you are wondering about?
Best AnswerAll of the times waking up. My girlfriends looks nothing like that. She might have 1 wakeup spike a night.
Best AnswerSomewhere in the Fitbit sleep help section, I was thinking perhaps right on the sleep display in the app if you scroll down, it says it is common to have several short wake periods during the night that you might not even remember. From my experience, I would say more that your girlfriend's is more unusual, in the good sense.
To me it looks like the Fitbit is registering particularly active sleep. The spikes are in the middle of deep periods without cycling through other stages. I would guess you were kicking or your heart rate went up or something like that.
Best AnswerThis is every night.
