Lights-Out in 600 Seconds A Technical Routine for Shortening Onset Latency

You’re not a patient—you’re a tinkerer. This concise, instrumented routine compresses the pre‑bed phase into a predictable 600‑second sequence that reliably reduces time‑to‑lights‑out. Built for hobbyists who enjoy dialing in systems, it combines breathing cadence, thermal cues, proprioceptive loading, and light hygiene in a clear, measurable order. Each micro‑step specifies exact durations, rhythms, and checkpoints, so you can run the sequence like a mini experiment and log results without guesswork. Expect less mental chatter, calmer physiology, and a smoother descent into deep rest.Inside you’ll get a timing diagram, quick‑start card, and troubleshooting trees for travel nights, late training sessions, and screen‑heavy evenings. No fluff—just the mechanics that move the needle, backed by practical explanations you can repeat and refine. If you like tinkering, timing, and tracking, this is your nightly edge.Run the sequence this evening and feel the delta. Then iterate. Your nervous system will thank you—and your mornings will show it.
