LuvemBooks Verdict

Best for

Curious adult readers who have ever struggled with snoring, sleep apnea, or asthma — or who simply want to understand what modern science and ancient tradition say about something they do 25,000 times a day — and who enjoy popular science journalism that blends personal narrative, global reporting, and wide-ranging research.

Worth it if

Worth reading if you want a sweeping, accessible entry point into the science and history of breathing that draws on both peer-reviewed pulmonology and millennia of medical tradition, delivered with the pace and storytelling craft of a veteran journalist.

Skip if

Skip it if you require a strictly hierarchical, clinically rigorous evidence base — Nestor moves freely between peer-reviewed studies, self-experimentation, and historical speculation, and readers who demand methodological precision may find the blended registers frustrating.

What readers & critics say

Kirkus Reviews called it "a welcome, invigorating user's manual for the respiratory system," while Publishers Weekly described it as "a fascinating treatise" on breathing; according to Wikipedia's coverage of the book's reception, Stuart Miller of The Boston Globe wrote that Nestor succeeded at "explaining both the basics" and the more complicated aspects of breathing properly. Bookmarks Reviews characterised the book as "brisk and detailed, a well-written read that is always entertaining" in its melding of the personal, historical, and scientific.

Breath: The New Science of a Lost Art is James Nestor's decade-in-the-making investigation into the history, science, and culture of breathing — arguing that chronic mouth breathing has quietly driven a measurable rise in snoring, sleep apnea, asthma, and allergies. Exceptional in breadth and accessibility, it draws on ancient breathing traditions, Stanford pulmonology research, and Nestor's own self-experimentation to make a compelling case that how we breathe matters far more than most of us realize. The key caveat: the book moves freely between peer-reviewed science, historical speculation, and personal narrative, so readers who demand strict methodological hierarchies may find certain sections — particularly those on ancient breathing practices — invite more scrutiny than others.
Is it worth reading?
For anyone curious about health, sleep, or simply the mechanics of something the human body does roughly 25,000 times a day, Breath delivers exceptional value. It debuted at number seven on the New York Times nonfiction bestseller list and spent 18 weeks on it in its first year, won the American Society of Journalists and Authors award for Best General Nonfiction Book of 2020, and was a finalist for the Royal Society Science Book Prize of 2021 — a combination of popular and critical recognition that is genuinely rare. Kirkus Reviews called it 'a welcome, invigorating user's manual for the respiratory system,' and Publishers Weekly described it as 'a fascinating treatise.' The main caveat is for readers who require strict methodological rigor: the book blends peer-reviewed research with historical speculation and self-experimentation in a way that prioritizes narrative accessibility over evidentiary hierarchy.
Similar books
Readers drawn to Breath will find strong companions in several books already curated on this page. Wim Hof's The Wim Hof Method covers overlapping breathwork territory with Hof's signature cold-exposure framework, while Jon Kabat-Zinn's Full Catastrophe Living approaches breath and body awareness through the lens of mindfulness-based stress reduction. For a broader science-driven health investigation with a similar blend of research and personal narrative, Peter Attia MD's Outlive is a natural next read. Michael Pollan's In Defense of Food makes a structurally similar argument to Nestor's — that modern habits have quietly degraded a fundamental biological practice — applied to eating rather than breathing. Gabor Maté M.D.'s When the Body Says No rounds out the group with its exploration of how chronic stress and suppressed emotion manifest as physical illness.
Who should read this?
Breath is designed for a broad adult readership and is particularly well-suited to anyone who has dealt with snoring, sleep apnea, asthma, or chronic congestion — conditions Nestor connects directly to chronic mouth breathing. Readers who enjoy popular science titles that blend personal narrative, global reporting, and wide-ranging research will find it squarely in their wheelhouse; psychiatrist Kate Womersley, writing in The Spectator, described it as 'playful and optimistic,' which captures its tone well. Those who prefer strictly hierarchical, peer-reviewed evidence will want to approach some sections — particularly those on ancient breathing practices like Pranayama, Sudarshan Kriya, and Tummo — with additional critical scrutiny. The book's translation into more than 35 languages and sales of over two million copies suggest its subject matter resonates across cultural and demographic lines.
About James Nestor
James Nestor is an author and journalist whose work has appeared in Outside, Scientific American, Dwell, National Public Radio, The New York Times, The Atlantic, Men's Journal, and the San Francisco Chronicle Magazine, among other publications.
What are the key takeaways?
The book's most actionable finding is what Nestor calls 'the perfect breath' — inhaling through the nose for 5.5 seconds and exhaling for 5.5 seconds, yielding 5.5 breaths per minute, a practice he presents as free and universally accessible. More broadly, Nestor argues that nasal breathing is dramatically superior to mouth breathing for health outcomes, and that the shift toward mouth breathing is tied to dietary changes — particularly the rise of processed foods — that have altered human jaw and airway anatomy over millennia. He also examines ancient breathing traditions including Pranayama, Sudarshan Kriya, and Tummo, situating them within a modern scientific framework built in part on Stanford University research.
Awards and critical reception
Breath's critical and commercial reception was exceptionally strong. It debuted at number seven on the New York Times nonfiction bestseller list for the week ending May 30, 2020, and spent 18 weeks on the list in its first year; it also became a bestseller in Germany, Spain, Croatia, Italy, and the UK, ultimately selling over two million copies worldwide with translations into more than 35 languages. It won the American Society of Journalists and Authors award for Best General Nonfiction Book of 2020 and was a finalist for the Royal Society Science Book Prize of 2021. Kirkus Reviews called it 'a welcome, invigorating user's manual for the respiratory system,' and Publishers Weekly described it as 'a fascinating treatise,' while psychiatrist Kate Womersley in The Spectator praised its 'playful and optimistic' blend of science and ancient technique.
Summarize this book

Summarize this book

Breath: The New Science of a Lost Art is a wide-ranging popular science investigation into why humans breathe the way they do — and why so many of us are doing it wrong. Nestor's central argument is that the human species has drifted away from nasal breathing toward chronic mouth breathing over millennia, a shift he links in part to the rise of processed foods, and one he connects to measurable increases in snoring, sleep apnea, asthma, autoimmune disease, and allergies. His reporting takes readers from ancient burial sites and secret Soviet facilities to New Jersey choir schools and the streets of São Paulo, weaving together ancient traditions like Pranayama, Sudarshan Kriya, and Tummo with cutting-edge research in pulmonology, biochemistry, and psychology. The book culminates in practical takeaways, including what Nestor calls 'the perfect breath': inhaling through the nose for 5.5 seconds and exhaling for 5.5 seconds.

Breath-Themed Content on Netflix Is Putting James Nestor's Book Back in the Conversation

A cluster of breath-and-diving-related content circulating on Netflix right now — including the documentary 'The Deepest Breath' — is nudging readers back toward James Nestor's Breath. It's a natural pairing for anyone who just watched something about the science and limits of human breathing.

If you've recently gone down a Netflix rabbit hole involving free-diving or breath-holding documentaries like 'The Deepest Breath,' you're not alone — and that renewed interest in what the human body can do with a single breath is bringing James Nestor's book back into the spotlight. Nestor's Breath covers similar territory from a science and history angle, making it a natural next step after watching athletes push their lungs to the limit on screen. The timing makes sense. When a documentary captures your imagination, books that dig deeper into the same subject tend to see a bump in readership. 'The Deepest Breath' is still available on Netflix, and conversations around it are picking up again in mid-June 2026. Nestor's book — which argues that most of us breathe badly and that fixing it can change your health — fits neatly into that curiosity. If you're the kind of reader who likes a documentary to have a companion book, this is a strong pick. Breath is accessible, research-backed, and covers everything from ancient breathing practices to modern sleep science. It's been a word-of-mouth hit since 2020, and moments like this are exactly why it keeps finding new readers.
