Sleep — 2026-07-29

8h 3min · 00:31→08:35 · REM: 11% · Deep: 31% · HRV: 140ms 🟢 · Resting HR: 51 bpm · Score: 87/100

HRV at 140ms is a new all-time high — 5ms above the previous peaks (135ms on Jul 5 and Jul 27), and the first time it's broken above your personal range of 76-134ms. Resting HR at 51 bpm is in the lower half of your range. Deep sleep at 31% (2h 30min) is solid, deep continuity at 73 points (normal). Light sleep elevated at 58% (slightly above the 55% reference), REM suppressed at 11% (52 min) — the REM suppression is consistent with being a bit high before bed (same pattern as Jul 20: 37% deep, 11% REM on heavy weed). Only 1 awakening. Breathing quality at 98 points is excellent, SpO2 at 98%.

The paradox: objectively the best recovery metrics in your entire run history (despite being high!), but subjectively you felt heavy and groggy — "barely woke up." The late bedtime (00:31) pushed the sleep window later, and waking at 08:35 after 8 hours likely pulled you out of a deep or REM cycle. Sleep inertia — the body recovered well but the brain wasn't ready to be awake yet.

Interesting that "a bit high" still boosted HRV to 140ms while suppressing REM. Jul 20 ("really high") gave 107ms HRV with 37% deep sleep. Tonight: lighter dose → same REM suppression but massively better HRV. The dose-response relationship here is notable — a little seems to help parasympathetic recovery, a lot tanks it.
