The Daily Harmony & Cortisol Calculator
Two inputs. One weighted balance algorithm. Move the sliders to your real numbers and the console estimates your Harmony Index and cortisol load band — then routes you to the exact guides in our library that repair whatever is dragging the score down.
Actual sleep, not time in bed. Adults need 7–9 hours for full glymphatic clearance.
Non-work scrolling, streaming and gaming. Exclude focused professional screen use.
Recovery engine at full capacity
Sleep and screen inputs are inside the high-performance band. Protect this configuration — it is your competitive advantage.
The Harmony Index is an educational heuristic modelled on population-level sleep and screen-exposure research, including clinical research on cortisol regulation. It is not a medical instrument and does not diagnose any condition. If you experience persistent sleep problems or anxiety, consult a qualified healthcare professional.
