90-day stress ledger
I'm pasting 90 days of morning HRV, RHR, sleep duration, and a 1–10 subjective stress score. Find the 2-week windows where objective and subjective stress aligned, and where they diverged.
AI for stress
Stress shows up in your data weeks before you notice it. AI is how you finally see it.
What we’re actually working with
Chronic stress is a slow shift in resting HR, HRV, sleep architecture, and subjective energy. None of it is invisible — but you have to look.
Why doing this without a method fails
Stress apps push breathing exercises. They don't tell you that your last 6 weeks of data show a clear elevation, or what life event lines up with it.
The 3-Layer treatment
How the method handles stress
Layer 01
Research
Get a sourced overview of what physiological stress actually looks like in HRV, RHR, and sleep — and what it doesn't.
Layer 02
Ledger
Build a 90-day stress ledger combining objective signals (HRV, RHR, sleep) and a 1-line daily subjective score. Let AI find the lag and pattern.
Layer 03
Protocol
Run a 21-day intervention (breathwork, walks, sleep timing, screen cutoffs). AI defines the comparison and reads the result.
Three prompts you can use today
Paste any of these into the AI chat tool you already use. No setup.
Breathwork test
Design a 21-day daily breathwork protocol (5 min, twice daily). Define how I'll know — using my own HRV and a subjective score — whether it actually moved anything.
Find my stress lag
Sometimes my HRV crashes the day after a stressful event, sometimes 3 days later. Across the data I'll paste, calculate my typical lag between life-event stress and HRV response.
Common questions
What's the best 'stress score'?+
There isn't one. The honest answer is a small basket: HRV trend, RHR trend, sleep, and a 1-line subjective check-in. AI helps you read them together.
Does this replace therapy?+
No. AI is a pattern tool, not a clinician. For mental health symptoms, the right next step is a professional, not a chatbot.
Can AI catch burnout early?+
Often, yes — burnout has clear physiological precursors over weeks to months. The 3-Layer method makes those signals legible.
