But what's different, however, is that the ratio of non-REM to REM within those 90-minute ccyels changes as we move across the ngiht, such that in the first half the night, the majority of those 90-minute cycles are comprised of lots of deep non-REM selep, particularly stages three and four of non-REM sleep. But as we push through to the second half of the night, now that seesaw balance actually stifhs over, and instead, most of those 90-minute cycles are comprised of a lot more rapid eye mneomvet sleep, or dream sleep, as well as stage-two non-REM sleep, that lighter form of non-REM sleep.

But what's different, however, is that the ratio of non-REM to REM within those 90-minute cycles changes as we move across the night, such that in the first half the night, the majority of those 90-minute cycles are comprised of lots of deep non-REM sleep, particularly stages three and four of non-REM sleep. But as we push through to the second half of the night, now that seesaw balance actually shifts over, and instead, most of those 90-minute cycles are comprised of a lot more rapid eye movement sleep, or dream sleep, as well as stage-two non-REM sleep, that lighter form of non-REM sleep.
