# Sleep — 2026-08-29

**7h 49min** · 02:14→10:06 · REM: 7% · Deep: 29% · HRV: 106 · Resting HR: 52 · Score: 85/100

> Sick-week sleep. Bedtime 02:14 is the latest in recent logs, but the night ran long (7h 49min) into a 10:06 rise — the "sick schedule" pattern (late to bed, late up, no alarm). HRV at **106ms** sits just under his excellent sober baseline (110–135ms) — the signature of the body still clearing the week-long cold, not of alcohol (no drinking involved). Resting HR 52 is mid-range (48–58), mildly elevated vs the 44–49 seen on clean nights — consistent with residual inflammation.

> Architecture is the one flag: **REM at 7% (37 min)** — the second consecutive sub-10% REM night in the pattern (5% on Aug 12, 7% now) — while light sleep inflated to 64% (High, ref <55%). The watch flagged it: "REM a little low; insufficient REM can affect your mental state." Illness is a known REM suppressor (fever, congestion, coughing disrupt sleep micro-architecture), and the 02:14 bedtime pushes REM into the morning hours where the watch detects it worst. Neither cause is a habit problem — this is a sick-week artifact, not a pattern to fix.
>
> Everything else held: deep sleep 29% (normal), deep continuity 78 pts, breathing quality 98 pts, woke once, SpO2 97%, respiratory rate 14 brpm. Score 85/100, better than 94% of users — the watch called the night "good" overall.
>
> **Context for the afternoon run:** same-day 13:38 run, first after 14 days off. The 106ms HRV + 52 resting HR predict the elevated run HR (157 avg, 29 min anaerobic at 7'08" pace) — the run data and the sleep data tell the same story: body recovering from illness, not broken.
