# Sleep — 2026-08-10
|
|
|
|
**8h 32min** · 00:24→09:19 · REM: 7% · Deep: 38% · HRV: **139ms** 🟢 · Resting HR: 49 bpm · Score: 87/100

> Recovery night after a brutal weekend. The 5am drinking night (see [[Sleep/2026-08-09]]) crushed HRV to **29ms — the lowest ever recorded** — with resting HR at 72 bpm. This night the body rebounded hard: 8h32min, deep sleep at 38% (3h 15min) — physical debt paid back. HRV at **139ms is the second-highest ever recorded** (140ms all-time high on Jul 29), sitting *above* the personal range of 78-136ms — full parasympathetic rebound once the system was clean.

> REM is the odd one out: only 7% (33 min). Classic post-deprivation pattern — the body prioritizes deep sleep first, and REM debt gets paid back *during the day*. Gutca reported napping a lot, struggling to wake, and dreaming heavily at the end of naps (couldn't recall the dreams) — that's daytime REM rebound, not a bug. Sleep inertia on top of a 09:19 wake made the morning feel heavier than the numbers suggest.

> **The cleanest takeaway — the contrast is everything:** drinking night (Aug 9) = HRV 29ms · HR 72 bpm · 4h33. Sober night (Aug 10) = HRV 139ms · HR 49 bpm · 8h32. That gap is the measured cost of a 5am drinking night — the worst recovery signal in Gutca's entire logged history. The good news: one clean night restored HRV to near-record levels, so recovery capacity is fully intact. The frequency of drinking/late nights is the pattern to cut, not the substance alone.
