What is implementation intentions health?

Implementation intentions health is a concept in personal epistemology: Agents for sleep exercise nutrition and stress management decisions.

Example: You decide once that your sleep agent operates as follows: trigger — it is 9:30 PM; condition — you are at home with no genuine emergency; action — begin the shutdown sequence (screens off, lights dim, phone on airplane mode). You do not renegotiate this every night. The agent fires. You comply. Over six weeks of consistent execution, the sequence becomes automatic — your body begins winding down at 9:30 before you consciously notice the time. You have converted a nightly negotiation into a reliable system. The same architecture applies to exercise (trigger: alarm at 6 AM; condition: no injury or illness; action: put on shoes and walk out the door), nutrition (trigger: hunger signal; condition: it is within a planned eating window; action: eat the meal you already prepared), and stress (trigger: notice chest tightening or racing thoughts; condition: not in physical danger; action: execute the four-count breathing protocol). Four domains, four agents, four sets of decisions you no longer burn willpower on.

This concept is part of Phase 21 (Agent Fundamentals) in the How to Think curriculum, which builds the epistemic infrastructure for agent fundamentals.
