Four guided audios, in my voice
Each audio walks you through a practice from the book in real time, with the pauses where you need them. Use headphones if you can, except near traffic.
The strawberry DNA experiment, step by step, with the waiting times built in, so your hands can stay busy.
The first hour of the morning, outside: light, green, and sound, as Chapters 10, 11, and 12 describe them.
A walk through your rooms as the evening begins: the lamps, the four questions from Chapter 14, and the two-minute notebook.
Sets up the night recording from Chapter 12, protects the bedroom, and fits your earplugs with you.



The Listening Workbook
The book explains why your surroundings reach your genes. The workbook is for trying it at home, with a pen.

DNA in Your Kitchen: pull a white thread of DNA out of a few strawberries.

Your Sensitivity Map: what overloads you and what restores you, channel by channel.

A Thirty-Day Plan: one small change to your surroundings at a time, and a way to see what it does.
The Evidence Map
Every claim graded in the book, gathered on a single page: 79 claims from 14 chapters, sorted into the book’s four seals. Read across a row to see what a chapter can promise, and what it can’t.

The book
How Light, Noise, Nature and Love Shape Our Genes, and the New Science of Why We Are All Sensitive to Our Environment, Some More Than Others
Your surroundings are always talking to your genes. This book follows the signal from your eyes, ears, and skin all the way down to the switches on your DNA, and asks why some of us hear it louder than others. Every claim carries one of four seals, so you always know how sure science is.
