Hormones, Stress & the Nervous System

Five guides on hormones, the menstrual cycle, chronic stress and breathing — without reducing every symptom to one chemical.

What you get

A 79-page reading edition plus all five guides as separate PDFs.

• How to Understand Your Hormones — 20 pages
• How to Eat For Your Cycle — 15 pages
• The Cortisol Cost — 15 pages
• Breathwork For Acute Daily Stress — 12 pages
• Deep Breathing Toolkit — 14 pages

Some of what is inside

• Why cortisol is a rhythm across a day rather than a single score
• Why your cycle is a pattern to observe, not a four-week prescription to follow
• What the small trials on ginger and period pain actually found, hedges included
• Breathing practices with their stop rules, and why ordinary breathing is always an acceptable choice
• Why recovery techniques cannot offset an unsafe job, uncontrolled pain or impossible caregiving

Who this is for

People tired of being told to lower their cortisol. The guides are clear about what self-care can do, what needs a clinician, and what should never be changed from a home test.

A note on how these are written

Every guide follows the same four moves: it names the popular claim, states what the evidence actually supports, gives you something specific to do, and tells you when to stop. You will find hedges in here. Where the research is thin, it says so. If you want certainty and secrets, these are the wrong books.

The Home Workstation Audit is a free six-page guide cut straight from this library — same voice, same hedges, same "here is when to stop" section at the end. No card, no trial. If you do not like how it reads, you have spent ten minutes and you know not to buy this.
