Comparing aspects of sleep recorded on Inspire 2.

[Pennylady]

I really love how this fitbit shows my sleep patterns but I can't see the precise times of awakening, increased pulse rates etc on my iphone; On my desktop when I sign into my account I can only find the "hours slept" chart with its tracking the type of sleep which is lovely but I am trying to work out why my pulse rate goes up suddenly in the middle of the night.  (Is it my cat yowling?  The milkman delivering at 3am? You know the sort of thing...)

Welcome to the forums @Pennylady.

Thanks for the details regarding sleep patterns.

Please take into consideration that there are a few scenarios where you might see your sleep pattern (which shows your time asleep, restless, and awake) instead of sleep stages:

• If you slept in a position that prevented your device from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your device higher on your wrist (about 2-3 finger widths above your wrist bone). The band should feel secure but not too tight.
• If you used the Begin Sleep Now option in the Fitbit app (instead of simply wearing your device to bed). For more information on automatic sleep tracking, see How do I track my sleep?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.

In addition, if you continue to experience the same difficulty, try to perform a restart following the steps listed here, this has been useful for other users experiencing something similar. 

And since the sleep stages depend on the heart rate information, I would also recommend following all the instructions in this article to improve the accuracy of heart rate information: How to I improve the accuracy of my heart rate rate reading?
