	👶 Irwin Feinberg’s team wired children aged six to eight and re-measured their sleep every six to twelve months for a decade, amassing more than 3,500 all-night recordings—about 320,000 hours—to show how deep {{Tooltip\|NREM}} swells, then recedes through adolescence as synapses are pruned and the {{Tooltip\|frontal lobes}} mature. Before birth, the fetus cycles between {{Tooltip\|NREM}} and REM by the second trimester and spends much of the day in REM-like sleep; in the third trimester, with no {{Tooltip\|REM paralysis}} yet, REM commands kick arms and legs that mothers feel. After birth, sleep starts polyphasic: a six-month-old averages ~14 hours with a 50/50 {{Tooltip\|NREM}}–REM split; by age five it shifts toward ~70/30, then to biphasic, and in late childhood becomes largely monophasic. In {{Tooltip\|autism}}, {{Tooltip\|circadian rhythms}} are flatter, nighttime {{Tooltip\|melatonin}} surges weaker, total sleep reduced, and REM deficient by 30–50%, aligning with known differences in neural development. Puberty pushes the clock later: melatonin rises later, teenagers fall asleep and wake later than parents, and early school start times collide with that biology. Through midlife, the ability to generate deep {{Tooltip\|slow-wave sleep}} deteriorates—by the mid- to late-forties, 60–70% of youthful deep {{Tooltip\|NREM}} is gone; by seventy, 80–90% is lost—while sleep fragments. Aging also advances melatonin’s evening peak, pulling bedtimes earlier, and frequent nighttime bathroom trips add fall risk and fractures. Older adults still require a full night of sleep; the difficulty lies in production, not demand. Across development, REM helps build the brain early, deep {{Tooltip\|NREM}} sculpts and stabilizes circuits in adolescence, and later-life fragmentation plus reduced {{Tooltip\|slow-wave sleep}} power undermine sleep even as need persists. ''That older adults simply need less sleep is a myth.''		👶 Irwin Feinberg’s team wired children aged six to eight and re-measured their sleep every six to twelve months for a decade, amassing more than 3,500 all-night recordings—about 320,000 hours—to show how deep {{Tooltip\|NREM}} swells, then recedes through adolescence as synapses are pruned and the {{Tooltip\|frontal lobes}} mature.
