▶ Sleep protocol
Sleep coverage uses tweet-backed and protocol-backed material: bedtime consistency, sleep front-loading, wearable/biological-age framing, and source-aware caveats around exact metrics.
Daily inputs, long-range targets, and explicit avoidances are separated into the same terminal panels as the BJ.WATCH reference. Source-aware summary only.

target 01 Frame sleep as a durable foundation feeding the broader biomarker and recovery system.concepts/blueprint-protocol.md
target 02 Treat the September 2026 Eight Sleep “sleep fingerprint” announcement as an attributed product-launch and research claim, not validated sleep science. The post’s figures match the BCG-FM preprint (Kjaer et al., arXiv:2606.07692: 2.04M hours from 136,575 participants; 3.26-year biological-age MAE; diabetes 0.852 / heart failure 0.822 / hypertension 0.810 / sleep apnea 0.792 AUROC), but it is a vendor collaboration behind a membership feature, its internal labels are self-reported, the preprint is not peer-reviewed, and the “better than Apple’s model” comparison is not in the paper. Johnson’s own post calls it “a research milestone, not a diagnostic device.”https://x.com/bryan_johnson/status/2095675388810936586
target 03 Treat Johnson’s September 2026 caffeine-mistake chronology as an algorithmic-health example—quantifying a mundane cafe error with a sound meter, order-screen inspection, and base rates—while keeping its “70–130%” injury-risk figure unverified. The nearest literature is chronic-sleep association in adolescent athletes (Milewski et al. 2014: 1.7× multivariate; von Rosen et al. 2017: up to 2.25× with rising training load), not acute single-night disruption. Skipping one session after a wrecked night is his personal decision, not reader sleep or training guidance.https://x.com/bryan_johnson/status/2095236652918812756
target 04 Use the June 19 seven-day checklist as a simple recurring-habits example, while preserving that readers need individualized medical guidance for health conditions.raw/articles/bryan-johnson/x-twitter-daily-2026-06-20.md
target 05 Treat Johnson’s reported 42-to-44 bpm sleep-heart-rate difference when his final meal moved from noon to 2 p.m. as an N=1 observation, not a causal estimate or universal meal cutoff.raw/articles/bryan-johnson/x-twitter-daily-2026-07-24.md
target 06 Keep jet-lag protocol material in a circadian-recovery / self-experiment bucket unless replicated and externally validated.raw/articles/bryan-johnson/x-twitter-daily-2026-06-19.md
target 07 Treat the June 2026 “one international trip per quarter” suggestion as Johnson’s biomarker-derived travel budget, not generalized medical advice.raw/articles/bryan-johnson/x-twitter-daily-2026-06-24.md
target 08 Add exact wearable targets only after source verification and keep them in claims/measurement context.concepts/biomarker-driven-longevity-protocols.md
