The Cortisol Myth

What stress hormones actually do, and what the internet gets wrong.

Type “cortisol” into your phone at 11pm and the shelf appears: resets, detoxes, protocols, all sold by people with something to sell. This book gathers the honest, free correction into one place — and puts a real doctor's judgment behind it.

Inside the book

  • What cortisol actually does — the survival hormone you'd die without, and why “high in the morning” is normal, not a crisis
  • “Cortisol face”, “cortisol belly”, the “detox” and the spit test — each held against real physiology to see what survives
  • “Adrenal fatigue” — the label endocrinology never accepted, and why the fake diagnosis can be genuinely harmful
  • Cushing's and Addison's — the rare cortisol diseases that are real, and exactly when a symptom means see your GP
  • A short, honest, no-product list of what actually moves stress physiology — each graded by how good the evidence really is

The honest part

A machine wrote this book. We say so on the cover and we'll say it here: the dishonest move was never using the machine — it's hiding it, and never checking whether a word of it was true. So a practising doctor read every page and threw out what didn't hold up. Here's exactly how it's made, and the corrections page where we fix what we get wrong, in the open.

Also in a collection

This book's full text is included in Body Signals, Checked ($6.99). Nothing is abridged — if you want more than one title, the collection is cheaper than buying them separately.
