Doubled sleep time over night

[RoseO]

By switching from "sensitive" to "normal" sleep mode, I have doubled my sleep time! Just what is Fit Bit measuring as "sleep" anyway?  I used to think I was a pretty good sleeper, until I got my Flex late last year. Suddenly, I had data that showed I slept on average 4 1/2 hours a night. Wow, I must be exhausted. I started reading about ways to improve my sleep habits and tried most of them. Nothing moved the Flex sleep numbers. Finally, I ended up with a doctor who sees the "data" and prescribes sleeping pills for the "problem." Before heading down the rabbit hole of sleeping meds, I decided to check the Flex setting and found that I was using "sensitive."  By changing the setting to "normal" (and no other changes), I went from consistently sleeping 4 1/2 hrs a night to 8 1/2 hrs a night. The "problem" was solved. I am pissed at being tortured with a problem I didn't have for eight months, but learned some good lessons: (1) listen to my body, not just the data; (2) understand how sleep attitude, physiology, and environment work; (3) check your Fit Bit settings; and (4) use Fit Bit for "comparative sleep" data, not "real sleep" data. z-z-z-z-z-z

Now you see why the sleep default setting is set to normal, it is the setting normal people use. If you want to track every movement of your arm while sleeping yhen use sensitive.
The only thing a Fitbit can monitor is movement,and add heart rate to the new ones.
So it monitors these paramaters to determine how deep of a sleep your in.

I do not wear my Fitbit One on my arm to measure sleep. I feel that arm movements are too frequent to measure my sleep. Instead, I fasten it to the waistband of my pjs. I think body movement is more accurate this way. My numbers seem to be more stable this way.

Also, I just started using a white noise app on my phone. This is also helping me with my sleep pattern.

@RoseOI recommend checking the clock to see the time you get into bed and subtracting it from the time you woke up to get an estimate of the time asleep. Once you have that estimate, I suggest comparing it to the time your Flex gives you, they shouldn't be too far apart. As @Rich_Lauementioned, "normal" is the recommended sleep sensitivity setting.

@SunsetRunnerHow do you like using the white noise app? Do you find that it helps to fall asleep? I wanna try one but I have issues falling asleep with noise and lights on during the night.
