# Sleep — 2026-09-19
**5h 30min** · 01:36→07:28 · REM: 17% · Deep: 26% · HRV: **63** · Resting HR: 57 · Woke: 1× · Score: 77/100
> 1.5 bottles of wine the night before, bed 01:36. HRV crashed to 63ms — below his personal range (78137) and well under the sober 110135 baseline — on a short 5h30 night.
**Interpretation:** The headline is alcohol, plain and simple. HRV **63ms** is in the *critical* tier (<78ms) — the worst number since the all-time-low 29ms crash (heavy drinking + 4.5h sleep back in Aug), and below even the usual heavy-drinking band (~71ms). Resting HR 57 is pinned at the very top of his personal range (4757), the classic alcohol signature. Bed 01:36 is also the latest bedtime in weeks, so the night stacks three of the four HRV killers at once: heavy alcohol, late onset, and short duration.
The one mercy is **architecture**: deep 26% and REM 17% are both dead normal, and light 57% is only mildly high (ref <55%). The body didn't fragment the way a stress night would — it just got short, boozy sleep. Score 77 (better than 51%) is right at the population median, which is what "5h30 + alcohol" buys you.
