# 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. Saturday night was out until 5am — but on **only 0% beers** (Gutca voiced concern about drinking nights being too common, then ran the experiment: no alcohol, same schedule). Sunday was a write-off on 4-5h sleep. This night: 8h32min, deep sleep at 38% (3h 15min) — the body paid back physical debt hard. HRV at **139ms is the second-highest ever recorded** (140ms all-time high on Jul 29), sitting *above* the personal range of 78-136ms — parasympathetic rebound after sleep deprivation, with no alcohol in the system to suppress it.

> 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 wrecking ball wasn't the alcohol — it was the 5am schedule. Same late night, zero booze, same wrecked Sunday. Worth honoring that out-loud observation: the *frequency* of drinking/late nights is the real pattern to address, not just the substance.
