Quick Take
- Narration: Roger May reads with a calm, unhurried quality that suits the subject matter unusually well, the pacing models the practice itself, and listening becomes something close to the slowing-down the book advocates.
- Themes: Forest bathing, biophilia, the health benefits of nature immersion
- Mood: Quiet and restorative, rich with sensory detail
- Verdict: The definitive English-language introduction to shinrin-yoku by the leading Japanese researcher in the field, the PDF companion is essential for the accompanying photographs.
I finished most of this one on a gray Saturday morning, sitting by a window with rain on the glass, which is perhaps not the optimal setting for a book about walking slowly through forests. And yet it worked. Yoshifumi Miyazaki’s prose has the quality of the practice it describes, there is no urgency, no optimization agenda, no demand that you transform your relationship to nature by chapter twelve. The book asks you to pay attention, and that request itself is the thing it is trying to teach.
Miyazaki is not a wellness influencer who discovered forest walks. He is a research scientist at Chiba University whose decades of fieldwork established the empirical basis for what was previously more intuitive, that time in forests measurably reduces cortisol levels, blood pressure, sympathetic nervous activity, and heart rate while increasing parasympathetic activity and natural killer cell activity in the immune system. The Japanese forestry agency developed shinrin-yoku as a public health practice in the 1980s partly on the basis of Miyazaki’s and his colleagues’ research, and this book is his own account of that science.
What the Research Actually Shows
The precision of Miyazaki’s scientific claims is one of the things that distinguishes this book from the broader nature-wellness category. He does not claim that forest walks cure illness or that biophilic environments are uniformly therapeutic. He reports what his studies measured: specific physiological responses to time in forest environments compared to urban environments, the role of phytoncides (essential oils emitted by trees) in triggering immune responses, and the particular quality of sensory stimulation in natural settings that differs from artificial equivalents.
One reviewer noted wanting more scientific detail about research methodology, the studies, what they specifically found, how they were conducted. That is a fair observation. The book is written for a general audience rather than a scientific one, which means Miyazaki cites his findings at a level of detail that satisfies curiosity without providing full research review. For a listener who wants the experimental basis rather than the applied conclusions, the primary research literature is the better resource. But for the intended audience, the balance is appropriate.
Bringing the Forest Indoors
One of the book’s more practically interesting sections covers biophilic design, the integration of natural elements into built environments. Wood surfaces, plants, natural light, water features: Miyazaki reviews evidence that exposure to these elements produces some of the same physiological effects as outdoor forest immersion, albeit more modestly. This section surprised me in its usefulness. For urban listeners who do not have ready access to forests, the chapter on bringing nature indoors offers something actionable beyond the core prescription of walking among trees.
Roger May’s narration is one of the better pairings I have encountered in this category. His voice has a quiet depth that does not demand attention so much as invite it, the pacing is genuinely unhurried in a way that distinguishes it from narrators who simply read slowly. The two-hour-fifty-one-minute runtime is tight for the subject, but the book earns its brevity. Miyazaki does not need five hours to make his case.
The PDF and the Visual Dimension
The accompanying PDF contains photographs that are central to the book’s experience. Shinrin-yoku is a practice organized around sensory detail, the quality of light through forest canopy, the texture of bark, the visual complexity of understory growth, and those details are inevitably diminished in audio alone. The PDF restores some of that visual dimension. This is one of the cases where downloading the companion materials before starting the audio meaningfully enriches the experience.
For Listeners Who Want the Science Behind a Practice They May Already Sense Works
This book is ideal for anyone who has noticed they feel better after time in natural settings and wants the empirical explanation for why. Miyazaki provides that without wrapping it in philosophy or wellness aspiration, and May’s narration lets the science breathe. Skip it if you are looking for a guided forest meditation experience or a detailed practical program, this is research and reflection, not instruction.
Frequently Asked Questions
Does the audiobook explain the science behind forest bathing, or is it mainly a practical guide to how to do it?
The balance leans toward science. Miyazaki is a researcher, and the book’s primary contribution is the empirical basis for why time in forests produces the physiological effects it does, cortisol reduction, immune system activation, parasympathetic nervous response. Practical guidance is present but secondary to the scientific explanation.
Is the PDF companion important enough to download before starting the audio?
Yes. The book includes photographs of forest environments and natural settings that are central to its sensory argument. Without the images, the audio is complete as scientific argument but loses the visual quality that makes shinrin-yoku a practice of seeing and attending as much as walking.
How does this compare to other nature-wellness audiobooks like Richard Louv’s Last Child in the Woods?
Miyazaki’s book is more narrowly scientific and less literary or policy-focused than Louv, and more focused on forest environments specifically than Louv’s broader nature-deficit thesis. They complement rather than duplicate each other, Miyazaki provides the physiological mechanism that Louv’s cultural argument assumes.
At under three hours, does the book feel complete or truncated?
For the scope Miyazaki intends, a scientific introduction to shinrin-yoku with enough depth to understand the research and enough practical guidance to begin the practice, the runtime is sufficient. One reviewer noted wanting more, but the brevity is a feature rather than an omission; the book delivers its argument efficiently.
