Tiny robot nanny tells me distressing things

My company gave everyone a Fitbit Charge for the holidays. Tiny robot nanny to wear on my wrist! To keep track of how much I move around! And to track my sleep patterns, if I wear it overnight. It tracks restless movement while I'm sleeping, and deducts that from the amount of time I'm supposedly "asleep".

I've been doing this for almost a week now, and hey, I think I found out why I'm always tired! According to my tiny robot nanny, I'm averaging between 5 to 6 hours of sleep a night, and I have a lot of restless, not-really-restful-sleep time. Last night I slept for 4 hours and 57 minutes, with an additional 103 minutes of restlessness. No wonder I feel tired right now.

I'm not sure what I can do to fix this, but the information is fascinating. (Yes, I know, I need to go for a sleep study. it will eventually happen.)
