A comment on Norepinephrine-mediated slow vasomotion drives glymphatic clearance during sleep. Parent comment

Another big learning from this is that "not all sleep is created equal." What happens during NREM isn't the same as what happens during REM.

Which surprises me because I thought we were all taught that REM is the best kind of sleep (and the hardest to induce). But also doesn't Ambien reduce the amount of time in REM and increase NREM.

I'm confused again. Someone better educated than me care to explain?

Hmm, I don't know about Ambien, but I didn't hear that REM is the best kind of sleep. On the contrary, REM sleep is the sleep level just below being awake, while what you really need is deep sleep, and when you're in really deep sleep, you're not dreaming.
