- The quality of breath is more important than the quantity.
Detailed Summary
Breath is divided into three parts, each exploring different facets of breathing.
Part One: The Experiment
- Chapter One: The Worst Breathers in the Animal Kingdom: Nestor recounts his experience participating in a Stanford University experiment where he and Anders Olsson plug their noses and are forced to breathe through their mouths for ten days. This chapter sets the stage by illustrating the immediate negative impacts of mouth breathing, including increased blood pressure, snoring, and fatigue.
- Chapter Two: Mouthbreathing: This chapter delves deeper into the harmful effects of mouth breathing, from reduced oxygen absorption to increased stress on the body. Nestor explores how mouth breathing disrupts the natural filtering and humidifying functions of the nose, leading to various health problems.
Part Two: The Lost Art and Science of Breathing
- Chapter Three: Nose: Nestor highlights the importance of nasal breathing, explaining how the nose filters, humidifies, and regulates airflow. He discusses the science behind nasal breathing, including the production of nitric oxide, which aids in vasodilation and oxygen absorption.
- Chapter Four: Exhale: The chapter focuses on the benefits of full exhalation and practices like the Five Tibetan Rites that can improve lung capacity and overall health. Nestor explores how proper exhalation can help to reduce stress and improve cardiovascular health.
- Chapter Five: Slow: Nestor explores the benefits of slow breathing, particularly "resonant breathing" or "coherent breathing," which involves taking approximately 5.5 breaths per minute. This technique, with 5.5-second inhales and 5.5-second exhales, can enhance heart rate variability, reduce blood pressure, and promote relaxation.
- Chapter Six: Less: The chapter delves into the concept of breathing less, exploring the Buteyko Method, which aims to reduce over-breathing and increase carbon dioxide levels in the body. Nestor discusses how Buteyko breathing can help manage asthma, anxiety, and other respiratory conditions.
- Chapter Seven: Chew: Nestor examines the importance of chewing for facial development and airway health. Drawing on the work of Weston Price, he illustrates how modern diets lacking in hard-to-chew foods contribute to crooked teeth and compromised airways.
Part Three: Breathing+
- Chapter Eight: More, on Occasion: This chapter explores techniques that involve temporary over-breathing, such as Tummo, to stimulate the nervous system and boost energy. Nestor discusses how these practices, when done correctly, can increase body temperature, reduce stress, and enhance overall well-being.
- Chapter Nine: Hold It: Nestor investigates the benefits of breath-holding, explaining how conscious apnea can reduce anxiety and increase resilience. He discusses the science behind breath-holding, including its effects on the amygdala and the nervous system.
- Chapter Ten: Fast, Slow, and Not at All: This chapter explores various advanced breathing techniques, including Holotropic Breathwork and Sudarshan Kriya, highlighting their potential to induce altered states of consciousness and promote healing.
Review
Breath is a captivating and informative exploration of a fundamental aspect of human health. Nestor masterfully blends scientific research with personal anecdotes, making complex concepts accessible to a general audience. The book's strength lies in its practical approach, offering readers actionable techniques to improve their breathing and overall well-being. However, some readers may find the breadth of information overwhelming, and the lack of definitive scientific consensus on certain techniques might raise concerns. Despite these minor drawbacks, Breath remains a valuable and thought-provoking read for anyone interested in optimising their health.
Actionable Takeaways
Here how to apply these lessons in real life:

- Slow Your Breath: Aim for a breathing rate of around 5.5 breaths per minute, with equal inhales and exhales.
- Chew Thoroughly: Incorporate harder-to-chew foods into your diet and chew each bite mindfully.
- Explore Breath-Holding: Experiment with breath-holding exercises to increase your resilience and reduce anxiety.
- Consider Advanced Techniques: If you're interested in exploring deeper states of consciousness and healing, research practices like Tummo, Holotropic Breathwork, or Sudarshan Kriya.
