I mean that people report (and their activity data suggests) sleeping but that the sympathetic response - "fight-or-flight" - didn't seem to turn down significantly from being awake. The best analogy, I think, is that your body should flip to idle during sleep, but we see that you're still running very hot.
- larrys 12y agoIt would be interesting if you could correlate that to what the person is doing physically during each sleep type. By way of a video device (similar to what is done with that part of a sleep study) that captures and can be played back or analyzed. I was actually going to set this up for a person with sleep apnea but they passed away before I could get the solution cobbled together. To summarize: Get a normal video capture (baby monitor etc.), capture video, analyze and play back video and see the differences..
- robg 12y agoThe accelerometer is actually really helpful. We are naturally paralyzed during deep sleep and REM, so that helps to distinguish those stages. Lighter sleep and being awake is easier as a kind, but less so as a degree.
- TravM 12y agoThis is fascinating, and it makes a lot of sense. Do you have any links to any research regarding this, for those that would like to learn more?
- robg 12y agoWe've been looking but besides the clinical reports of sleep disturbances and night tremors, we're not finding physiological evidence of sympathetic activation. It's where we get excited by doing the research as a community of users.
