Sleep — 2026-09-05

10h 17min · 23:15→09:59 · REM: 15% · Deep: 39% · HRV: 98 · Resting HR: 56 · Woke: 2× · Score: 78/100

"After a week of not sleeping enough and yesterdays run, almost 11 hours in bed." Sober. Bedtime 23:15 — pre-midnight again, the lever working — and slept until 09:59: 10h 44min in bed, 10h 17min tracked.

Interpretation: This is textbook sleep-debt repayment — and it was earned, not indulged. The architecture says it all: deep sleep 4h 02min (39%), the largest deep block in the log, with deep-sleep continuity at a perfect 100. After sleep restriction, the body repays deep sleep (SWS) first and hardest — that's the physical repair shift running at full power, repairing a week of short nights plus Friday's 5 km in the heat. REM 15% (1h 31min) normal, light 46% normal, breathing quality 98. The score docked to 78 for two cosmetic reasons — duration above the 6-10h reference and 2 wake-ups — which is the watch missing the point: one long sleep after a debt week is the prescription, not a violation. Ignore its "sleeping in affects your rhythm" lecture; that risk only exists if the late rise becomes the pattern. Tonight returns to the normal rhythm.

The honest caveat — recovery is mid-flight, not finished: HRV 98ms (lowest sober reading since Aug 12's 112) and resting HR 56 (top of range, vs 48 on the Sep 2 record night) show the autonomic bill from the week is still being paid — yesterday's zone-4-heavy run in 28°C heat was real stress, and last night's deep-sleep marathon was the body's answer. Expect tomorrow's (Sunday) morning read to look cleaner if tonight lands ~23:00. The trajectory across nights: 145 (Sep 2, rested) → 111 (Sep 4, short) → 98 (Sep 5, repaying) — this is the dip mid-recovery, not a new baseline.

Role in the week: this sleep sits between Friday's run and Sunday's 6 km long run — it's the refuel that makes Sunday safe. Rest day today; legs should feel the deep-sleep dividend tomorrow.
