ODD

Why is it that I woke up very early this morning feeling rejuvenated after only a few hours of sleep, but frequently after eight or nine hours of sleep I'll wake up exhausted? Does it depend on what part of the sleep cycle I wake up during?

I've found that very little sleep, I can manage, and 7-9 hours I'm ok, but that in-between time of 4-6 hours, I feel like I'm dying. It probably is sleep cycle related.

It turns out there is a product called "Wakemate" that purports to help you wake up at the proper time in your sleep cycle. I am dubious.

Likely you're much more refreshed-feeling when you wake during REM sleep, which is very near the awake state in terms of level of cortical arousal and encephalographic rhythms and such; the transition is much less abrupt.

Now that is a first-class comment.
