If I lay awake but don't move at all, it's going to say I slept then. In fact, I've been entranced, reading a long article on my computer, when it has said I was asleep. So I know it's not completely accurate but I like to look at my sleep results anyway.
I do have sleep apnea and have had it all my life. I've had several sleep tests. I was wired up like a porcupine each time. So it's understandable that this simple device can't be too accurate by just touching your skin.
I also will get large blank spots on my chart and assume I must be on my left side when that happens and may have caused the sensor to come away from the skin somehow.
