Understanding physiology, equalisation, relaxation, safety, technique and the psychology of being underwater can make the difference between simply attempting freediving and genuinely understanding the discipline.
Books cannot replace professional freediving instruction or a trained safety buddy, but the right books can deepen your knowledge and help you become a more informed freediver.
Here are some of the best freediving books to read in 2026, from practical training manuals to books exploring the science, history and philosophy of breath-hold diving.
1. Manual of Freediving
Manual of Freediving: Underwater on a Single Breath by Umberto Pelizzari and Stefano Tovaglieri is one of the best-known technical references in the sport.
It covers breathing, relaxation, physiology, equipment, equalisation, training methods and the major freediving disciplines. The book is detailed and methodical, making it particularly useful for readers who want a traditional, comprehensive manual.
Best for
Students, instructors and experienced freedivers who want a detailed technical reference.
Why read it?
Its strength is breadth. It brings a large amount of established freediving knowledge into one volume and remains an important reference for serious students of the sport.
2. Freediving Fundamental Guide
Freediving Fundamental Guide: The Freediver's Ultimate Handbook by Bassel Ounah is a modern, structured guide designed to support the full freediving journey, from preparing for a first course to refining knowledge after certification.
It covers equalisation, breath-hold physiology, CO₂ tolerance, relaxation, pool and depth disciplines, risk management, buddy procedures, emergency awareness, training planning and the mental side of freediving.
The guide places strong emphasis on safety and on understanding why the body responds as it does, rather than simply following exercises. It is also available as a 9-hour 11-minute unabridged audiobook, which makes it practical for learning while travelling, training or preparing for a course.
Best for
Beginners, certified freedivers, instructors and listeners who want one accessible guide connecting technique, physiology, safety and mindset.
Why read it?
It provides a clear pathway from foundational knowledge to more advanced understanding, with a safety-first approach throughout.
3. Oxygen
Oxygen: A Memoir by William Trubridge offers a very different perspective. Rather than functioning as a training manual, it explores the life and experiences of one of freediving's most accomplished athletes.
The book gives readers insight into elite performance, competition, risk, motivation and the personal commitment behind world-record freediving.
Best for
Readers interested in elite freediving, personal stories and the mindset of a world-class athlete.
Why read it?
It shows the human experience behind extraordinary depth and offers inspiration beyond technical instruction.
4. Deep
Deep: Freediving, Renegade Science, and What the Ocean Tells Us About Ourselves by James Nestor is an engaging exploration of freediving, marine science and the hidden capabilities of the human body.
Nestor follows freedivers, scientists and ocean researchers to examine pressure, adaptation, echolocation, marine mammals and our relationship with the deep ocean.
Best for
General readers, ocean enthusiasts and new freedivers who want an accessible, story-driven introduction.
Why read it?
It captures the wonder of the underwater world and explains why freediving has become a gateway to understanding both the ocean and ourselves.
5. Breatheology
Breatheology: The Art of Conscious Breathing by Stig Severinsen explores breathing as a tool for health, relaxation, performance and mental control.
Although it is not exclusively a freediving manual, its discussion of breath awareness, stress regulation, relaxation and breath-hold training is highly relevant to freedivers.
Best for
Readers interested in breathing, wellbeing, mental performance and the connection between freediving and everyday life.
Why read it?
It expands the value of breath training beyond depth and distance, showing how conscious breathing can influence focus, calm and resilience.
Which freediving book should you read first?
The best first book depends on what you want from freediving.
- For a comprehensive traditional manual: choose Manual of Freediving.
- For a modern, structured and safety-centred guide: choose Freediving Fundamental Guide.
- For an elite athlete's personal journey: choose Oxygen.
- For ocean science and storytelling: choose Deep.
- For breathwork, relaxation and everyday performance: choose Breatheology.
If you are preparing for your first course, begin with a book that explains safety, physiology, equalisation and buddy responsibilities clearly. Once you understand the foundations, narrative and specialist books can broaden your perspective.
A book is not a substitute for freediving training
Reading can improve understanding, but freediving requires supervised practice. Equalisation, rescue skills, recovery breathing, buddy positioning and safe progression must be learned with a qualified instructor and practised with a trained buddy.
A recommended freediving reading path
- Start with the foundations: read Freediving Fundamental Guide or Manual of Freediving alongside a recognised beginner course.
- Understand the wider world: read Deep to explore the science, people and oceans surrounding freediving.
- Learn from elite experience: read Oxygen for insight into high-performance freediving and the person behind the records.
- Develop breath awareness: read Breatheology to connect breath, relaxation, focus and life outside the water.
- Return to your technical books: revisit the practical chapters as your training progresses. The same ideas often become more meaningful after real supervised experience.
Final thoughts
The best freediving books do more than promise longer breath-holds or greater depth. They help readers understand pressure, physiology, technique, safety, mindset and the responsibility that comes with entering the water on a single breath.
Choose the book that matches your present stage, learn with qualified supervision, and return to the material as your experience grows.
