+> First sober night after the festival (Thu-Sat). The autonomic numbers are stunning: HRV at 135ms ties your all-time peak (Jul 5), and resting HR at 48 bpm is actually *below* your personal range — your body is in deep parasympathetic recovery mode. But the sleep architecture tells the other half of the story: light sleep dominated at 68% (way above the 55% reference), REM was suppressed at just 11% (1 hour), and you reported no dreams. This is classic post-extreme-exertion sleep — the body is physically repaired, but the brain is still processing a massive backlog. 150K steps in a week + alcohol + weed + late nights = the CNS has a lot of cleanup to do. The single wake-up and perfect breathing quality (100) are the silver linings. This sleep was a recovery sleep, not a restorative sleep — effective for the body, still catching up for the mind.
+>
+> The watch flagged bedtime at 00:10 as "a little late" and noted it occurred multiple times in the past days — fair. But given you got nearly 9 hours, that's a minor note.
