A healthy night moves through 4–6 cycles of roughly 90 minutes, each containing light (N1/N2), deep slow-wave (N3), and REM sleep. Deep sleep clusters in the first half of the night and drives physical repair; REM clusters in the second half and drives memory consolidation and emotional regulation. Two people can both sleep 7 hours and have very different architecture — which is why wearable stage data, read alongside biomarkers like , , and morning cortisol, is more informative than duration alone.
