Chapter summaries
Email Apnea and Breathing Under Stress
James Nestor describes 'email apnea,' where office workers stop breathing or breathe dysfunctionally at their inboxes, and links it to a stress response. Dr. Chatterjee reframes it as the body doing what it is designed to do and suggests transition times and breathing before meals.
- •Dr. Margaret Chesney's 'email apnea': an estimated 80% of office workers stop breathing when they open email
- •Chronic dysfunctional breathing can have effects like sleep apnea, including spiking blood glucose and adrenaline
- •Chatterjee says the body isn't broken, it just needs a different signal that there is no tiger
- •Chatterjee recommends transition times and a three, four, five breath before eating
- •Breathing is a two-way street between brain and organs
Grace Before Meals and the 5.5 Breaths-per-Minute Rhythm
The conversation turns to grace before meals as a lost art with a scientific basis. Nestor explains that prayers from many traditions lock into a rate of about 5.5 breaths per minute.
- •Grace before a meal may calm the body ahead of eating
- •Chatterjee calls it a lost art and says he wrote about it in his fourth book
- •Prayers from Buddhist, Kundalini yoga and Catholic traditions converge on about 5.5 seconds in and out
- •Italian researchers said this is probably no coincidence
Nasal Breathing for Athletic Performance and Recovery
Chatterjee brings up his videographer's faster recovery with nasal breathing, and Nestor explains the athletic science. Both describe using the nose as a barometer for exercise intensity.
- •Nasal breathing allows harder work at a lower heart rate and more efficient oxygen use
- •Sanya Richards-Ross and research by Dr. John Douillard are cited
- •Acclimating to nasal breathing can take weeks or months
- •Patrick McKeown's rule: never work out harder than you can breathe correctly
- •Chatterjee uses nasal breathing instead of a heart rate monitor
Breathing as the Next Wave of Health Awareness
Nestor compares breathing awareness to the eventual understanding that processed food is harmful. Chatterjee then clarifies that the concern is habitual mouth breathing, and Nestor adds that occasional mouth breathing is fine.
- •Nestor sees breathing as the next thing, after about 20 years of science on processed food
- •Chatterjee advises practicing nasal breathing and six to eight breaths a minute
- •Occasional mouth breathing, such as laughing or swimming, is fine
- •The issue is chronic habit, not a few hundred breaths a day
Over-Breathing Practices: Wim Hof, Yoga's Origins and Breath Diversity
Chatterjee asks about conscious over-breathing methods such as the Wim Hof technique. Nestor explains that deliberate stress practices can give conscious control over autonomic functions, and discusses yoga's origins and the common core of breath practices.
- •Conscious over-breathing differs from unconscious over-breathing
- •Practitioners with autoimmune conditions report symptom reductions
- •Early yoga was only breathing and focusing; Vinyasa flow is about 100 years old
- •A free diver told Nestor there are as many breath practices as diets
- •Wim Hof method, Tummo and Sudarshan Kriya share breathing intensely then slowly
Free Diving, Fear and Practical Starting Advice
Chatterjee asks about free divers, and Nestor says free diving works as forced meditation and that he has never met an anxious free diver. Chatterjee mentions the fear study involving CO2, and Nestor advises people to test breathing for themselves.
- •Many free divers had anxiety, depression or addiction before diving
- •Free diving cannot be done while panicked or stressed
- •Chatterjee notes fear and anxiety can be physiological, not only caused by external events
- •Nestor suggests measuring blood pressure before and after six-breaths-a-minute practice
- •Start small and give it a week
Swami Rama and ADHD-Linked Breathing
Nestor first links childhood ADHD to sleep-disordered breathing, then recounts the Menninger Clinic tests of Swami Rama. Rama showed control of brain states, heart rate and hand temperature.
- •Nestor says about 75% of kids with ADHD also have sleep-disordered breathing
- •Dr. Steven Park's work on better breathing in children
- •Rama stayed conscious in a delta brain state and raised his heart rate to over 300 beats per minute
- •He varied the temperature on one hand by 11 degrees
- •Nestor says doctors still write to dispute the account
Skepticism, Wim Hof and Breath as Foundation of Health
The two discuss skepticism about extreme breathing feats and why Wim Hof is relatable. Nestor argues these are human abilities anyone can hone, and that breathing is as fundamental as diet, exercise and sleep.
- •Nestor says he reports rather than evangelizes
- •Herbert Benson's Harvard study in Nature and Hof's endotoxin training study are cited
- •Chatterjee says breath touches every part of life, including relationships and sleep
- •Nestor says most energy comes via oxygen, and food needs breath to work
- •Szent-Györgyi's quote that our shortcomings are due to abusing the body
Posture, Biomechanics and Scoliosis
Chatterjee asks how posture affects breathing. Nestor describes Dr. Belisa Vranich's out-and-in breathing test, Chatterjee shares his spiral breathing experience, and Nestor discusses scoliosis and Katharina Schroth's orthopedic breathing.
- •Hunched posture limits lung inflation
- •Vranich's test: hands above the hips should move outward laterally when breathing in
- •Chatterjee's spinal alignment changed after three minutes of spiral breathing
- •Nestor discusses a possible link between dysfunctional breathing and scoliosis
- •Schroth's breathing method is still used at Johns Hopkins
Lung Capacity and Longevity
Nestor explains that lung size and function are linked to lifespan, citing the Framingham Study. He says lung capacity declines with age but can be preserved through healthy breathing, stretching and exercise.
- •Framingham Study found lung size and function the most significant marker of lifespan among 5,200 people
- •A study of lung transplant recipients found larger lungs lived longer
- •Lung capacity drops after about 30, especially in the 60s and 70s
- •Nestor says people can eat well and exercise but won't be healthy if breathing incorrectly
Breath: The New Science of a Lost Art
Chatterjee asks about the book's subtitle, and Nestor explains that breathing knowledge has repeatedly been found, forgotten and rediscovered. Nestor says he approached the topic as a journalist with no slant and describes the simple foundation of healthy breathing.
- •Conscious breathing practices date back 3,000 to 4,000 years
- •'Lost and Found' might be a more accurate title
- •About half the experts initially told Nestor breathing doesn't matter
- •The foundation is nose breathing, longer exhales, breathing less and slowly
- •Nestor does intense breathwork three or four times a week, usually at night
Nasal Breathing, Mouth Taping and Sleep
Nestor explains what the nose does for incoming air and describes his own shift from mouth to nose breathing. He covers sleep taping and the evidence behind it, as well as how ancient skeletons suggest larger airways.
- •The nose humidifies, pressurizes and filters air; 25 to 50% of people habitually mouth breathe
- •Nestor woke with a dry mouth for decades before learning from Dr. Jayakar Nayak at Stanford
- •He uses a small piece of tape across his lips and warns against sketchy YouTube methods
- •Anne Kearney is starting a Stanford study of 200 people on sleep tape
- •Nasal breaths bring 20% more oxygen than mouth breaths
Soft Food, Chewing and Facial Structure
Nestor says ancient skeletons had larger airways and straight teeth, while modern soft diets have led to smaller mouths. The two discuss chewing, infant feeding and baby-led weaning.
- •Skeletons older than 400 to 500 years show powerful jaws and large nasal apertures
- •About 90% of people today have some tooth crookedness
- •Softer food and less chewing are cited as the main cause of smaller mouths
- •Breastfeeding versus bottle-feeding affects facial growth
- •Chewing tough foods from many diets can provide jaw stress
Reader Feedback and Integrating Eastern and Western Medicine
Nestor describes readers' frustration at not having learned about breathing for asthma, and the discussion turns to why medicine overlooks milder chronic conditions. Brian McKenzie's quote about Eastern and Western medicine frames the case for integration.
- •Readers feel frustrated that they learned about asthma reversal from a book
- •Nestor says doctors focus on acute and serious problems
- •McKenzie's quote: Eastern medicine is great if you want to live, Western medicine if you don't want to die
- •Nestor says top institutions are moving toward integrating the two
Slow vs. Intense Breathing, Stress and Choosing a Practice
Chatterjee asks how to reconcile breathing less with Wim Hof-style over-breathing. Nestor explains that both are right for different goals, how periodic stress differs from chronic stress, and that people with anxiety or panic should start slowly.
- •Breathe slowly through the nose most of the day; use intense breathing for short controlled stress
- •Wim Hof-style sessions are about 20 minutes, like interval training for stress control
- •Chronic low-grade stress drives inflammation and chronic disease
- •Changes in blood pressure and EEG can be seen within minutes
- •Anxious or asthmatic people should start with three seconds in and out
CO2 Tolerance, Breath Holds and Carl Stough's Olympic Story
Chatterjee describes his walking breath-hold practice, and Nestor discusses CO2 tolerance in panic and asthma, including Dr. Justin Feinstein's work. He then recounts Carl Stough's diaphragm retraining of singers, emphysema patients and the 1968 US Olympic runners.
- •Chatterjee uses breath-hold ability as an early warning sign of stress
- •Breath holding appears in ancient Hindu and Chinese practice
- •People who can't hold their breath long are more susceptible to panic and asthma
- •Stough retrained emphysema patients through breathing alone
- •Stough's US runners in Mexico City were the only team not to use oxygen
