I purchased the JawBone UP 3 wrist band about a month ago. (Under $80.00)
Originally bought it to monitor steps.
(I have discovered I'm more of a couch potato that I thought.).
Anyway, downloaded the App for the JawBone and discovered it tracks sleep cycles, so decided to start wearing it to bed.
I was a bit skeptical about how accurate this might be.
The app gives you a graph of what time you went to bed and the time you woke up. It also lists wake times during the night. Although, I very seldom get up during the night, I find the reporting is accurate.
It also lists sleep cycles and labels them as Light Sleep, Deep Sleep, and REM. I have been trying to compare this with SleepyHead Graphs to try and pinpoint REM sleep.
I'm unsure as to the difference in their listing between Deep Sleep and REM, but it looks like my respiration goes up during REM Sleep.
Like I said, I was a bit skeptical about it's accuracy, but compparing to SH, it is quite interesting.
I've only used it now for a couple weeks, but it give me some idea as to my sleep cycles.
The Up band gives no information by just looking at it. You have to download the UP app. I open the app on my IPad, then open up sleepyhead on my desktop to compare.
It would be nice to find a device that would allow the sleep stages to be imported into SleepyHead. Or, you would think, that with the cost of CPAP machines, that the major players like ResMed and Phillips Respironics would incorporate this information into the data. Maybe some day.
