Falling asleep instantly the moment your head hits the pillow isn't a sign of good sleep — it's a sign of sleep debt or exhaustion.

The post runs through ten dramatized claims about cortisol and a nervous system "stuck in survival mode" — many read more like interpretation than measurement (pinning every night waking or "10pm energy surge" on cortisol is a simplification with no source attached). Stripped of that staging, the most checkable and useful claim is the one about sleep-onset latency: reference benchmarks (Sleep Foundation, Cleveland Clinic, and a meta-analysis of 110 cohorts using the multiple sleep latency test) put normal latency at roughly 10 to 20 minutes; falling asleep in under 5 to 8 minutes is a recognized sign of excessive daytime sleepiness and often accumulated sleep debt, not a "superpower." That benchmark is solid and well documented clinically. The list's other items (night sweats = cortisol, racing mind at lights-off = unprocessed stress) remain plausible hypotheses but aren't quantified in the post, and deserve more caution than the sleep-latency point.

No named source held this one up — that absence is part of the verdict.
