Every day, people using Cōrta log the same handful of signals: how they slept, their morning energy, the protocol steps they followed, the supplements they took, and how they felt by evening. On its own, one person's log is a private feedback loop for resetting their own cortisol rhythm. But at scale — stripped of anything that could identify anyone — those check-ins add up to something bigger: a real-world picture of what actually moves the needle on stress and cortisol across thousands of people.
That's what this page is for. Cortisol Trend Reports are periodic write-ups built from aggregate, anonymized data — never individual records. Expect the kind of questions you can't answer from a single lab test: which habits correlate with better sleep and steadier energy, how morning light and delayed caffeine track against reported afternoon crashes, which supplements people reach for most, and how following a structured protocol changes the shape of a typical day. If you want the grounding first, start with what cortisol is and why its daily rhythm matters more than any one number.
We're holding the first report until after launch, when there's enough real usage to say something honest and useful rather than something premature. When it publishes, it lands here — and waitlist members get it first.
