Broken Sleep Pattern

[RUTD]

If I wake up in the night and decide to read for a while my fitbit gives me a score for both parts of my nights sleep rather than putting them together with a reading break in the middle, why?

Hi, @RUTD , welcome to the forums!

The short answer to your question is that this is how it is designed.  Your Fitbit is designed to recognize sleep automatically and also to recognize when sleep ends automatically.  It does this by a combination of detecting movement and reading your heart rate. 

It sounds like when you wake up to read you really wake up quite thoroughly, probably sit up in bed, and that your heart rate returns to your personal normal when awake and alert.  That combination of factors will alert the Fitbit to end a sleep session.  Once you stop reading, lie back down and start to show body signs of sleep, the Fitbit will begin a new sleep session.

I am not sure that there is a way around this, if that is your sleep pattern.  There is the option to start and end sleep manually (using the app).  If you do that, however, you will not get the detailed analysis of “sleep stages” in the app.  (You also will not get sleep stages if your middle of the night reading activity means that your sleep sessions last fewer than 3 hours).
