Why a Skeptical Journalist Wrote a Book on Breath
Dr. Chatterjee welcomes James Nestor and asks how a science journalist who was skeptical of breathwork came to write Breath. Nestor explains that the pieces came together over years, starting with an experience he could not explain and his later work with free divers.
- •Nestor never planned to write about breathing; the pieces came together over several years
- •The average person breathes about 25,000 times a day and takes in about 30 pounds of air
- •Nestor argues breathing matters more than food or exercise for health
- •Free divers and the researchers studying them showed him the potential of breathing
The Lost Art: Why Breathing Knowledge Keeps Being Forgotten
Nestor explains the book's subtitle: breathing practices have been studied for thousands of years, forgotten, then rediscovered. The conversation turns to why interest is growing now and how Nestor approached the science as a journalist with no slant.
- •Conscious breathing practices date back 3,000 to 4,000 years across cultures
- •Discoveries about breathing were repeatedly lost and renamed
- •New instruments now let researchers measure how breathing affects mind and body
- •About half the experts Nestor first spoke to said breathing doesn't matter, while long-time researchers said it affects everything down to bone density
A Simple Foundation: Slow, Nasal, Light Breathing
Chatterjee asks whether there is a base-level practice everyone should follow amid so many methods. Nestor says most techniques lead to the same conclusions and gives his simple foundation, plus how he fits healthy habits into everyday life.
- •Ancient Chinese, Hindu, yoga and psychiatric practices are all doing the same thing
- •The foundation is breathing through the nose, exhaling more, breathing less and breathing slowly
- •Nestor does intense breathwork three or four times a week, usually at night
- •Healthy breathing habits can be adopted while at a computer or watching Netflix
Nasal vs. Mouth Breathing and Mouth Taping
Nestor describes what the nose does for incoming air and how he went from a lifelong mouth breather to a nasal breather. He explains mouth taping at night, with tips and the measured results reported.
- •The nose humidifies, pressurizes, filters and conditions air
- •25 to 50% of the population habitually mouth breathes
- •Nestor used a small piece of tape to train his mouth shut at night after meeting Stanford's Dr. Nayak
- •Nestor reports emails from people whose chronic snoring and mild-to-moderate sleep apnea went away
- •Nasal breathing delivers about 20% more oxygen than mouth breathing
Shrinking Jaws, Soft Food and Airway Development
Chatterjee asks whether sleep apnea is a modern problem. Nestor points to skeletal records showing ancestors had bigger airways and straight teeth, and attributes smaller mouths mainly to soft, processed food and less chewing, which also leads into baby-led weaning.
- •Skeletons older than about 400 years show powerful jaws, large airways and straight teeth
- •Today 90% of people have some crookedness in their teeth
- •Softer diets and less chewing are the main cause of smaller mouths
- •Breastfeeding versus bottle-feeding affects facial growth, and baby-led weaning is a growing revolution
- •Chewing hard natural foods applies across diets, such as carrots and celery
Remodeling the Face as an Adult and Chewing on One Side
Nestor describes his own year-long experiment with a palate expander, with CT scans before and after. He then explains why chewing on one side at a time may trigger a relaxation response.
- •The maxilla is a bone that can be remodeled at almost any age
- •Nestor's airway opened about 15 to 20% and he gained about five pennies' worth of bone
- •A palate expander isn't required; chewing can help tone the airway muscle
- •Side-to-side chewing is linked to a parasympathetic response, while clenching both sides spikes a sympathetic response
Breathing as the Great Unifier and Western Medicine
Chatterjee describes breath as a unifier across many conditions, and Nestor stresses that breathing science complements rather than opposes Western medicine. He says the body is one connected system and shows how breathing can quickly shift blood pressure.
- •Breathing is free and available to everyone
- •Nestor's father-in-law is a pulmonologist and his brother-in-law an ER doctor, and he values Western medicine
- •Siloed medical care misses that the nose, airway and lungs are one system
- •Breathing lets us influence functions we can't otherwise control consciously
- •Nestor can lower his own blood pressure 10 to 15 points in two minutes of certain breathing
Asthma, Emphysema and Breathing Protocols
Nestor explains how over-breathing and low CO2 contribute to asthma and cites a study of 120 asthmatics. Both speakers stress that inhalers and medication remain essential and that people should not stop treatment without consulting their doctor.
- •Asthmatics tend to breathe too much and blow off CO2, causing vasoconstriction
- •A study of 120 asthmatics using a CO2-tracking device showed fewer attacks and better respiratory function
- •Nestor wants asthmatics given information about breathing protocols alongside medication
- •Carl Stough taught breathing to emphysema patients who then walked out of VA hospitals
- •Both speakers say not to reduce prescribed medication without medical consultation
Why Breathing Less Is More Efficient
Chatterjee asks why breathing less is better when oxygen seems good. Nestor explains dead space and efficiency at different breathing rates, links over-breathing to cold fingers, and discusses how normal respiratory rate guidelines have shifted.
- •At 20 breaths per minute only about 50% of the air is usable, versus about 85% at six breaths per minute
- •Slow breathing lowers blood pressure and increases diaphragm movement
- •Over-breathing causes vasoconstriction, producing cold or tingling fingers
- •Nestor's father-in-law says the accepted normal rate was 8 to 12 when he was in medical school
- •Slow breathing around six breaths a minute produces heart rate variability coherence
Start Small: A Few Minutes of Slow Breathing a Day
Both speakers emphasize the big picture rather than exact numbers: anything from four to 10 breaths a minute helps. Nestor describes uses for anxiety, depression and eating disorders, and Chatterjee links it to stress eating and weight.
- •Four to 10 breaths a minute brings benefits, and six is a simple target
- •Doctors Gerbarg and Brown use slow breathing for anxiety, depression, bulimia and anorexia
- •Five minutes a day can affect blood pressure
- •Chatterjee links stress-driven eating to the value of breathing practice
- •Nestor ties chronic stress, blood sugar and metabolic problems together
The Vagus Nerve, Panic Attacks and Email Apnea
Nestor describes Stephen Porges's vagus nerve research and a study predicting panic attacks from falling CO2. He then explains email apnea, and the two discuss transition times and calming before meals.
- •The vagus nerve connects organs to the brain, and constant stress cuts those signals
- •Alicia Meuret predicted panic attacks about an hour ahead using CO2 levels, and slowing breathing reduced attacks
- •Margaret Chesney's email apnea describes people holding their breath at their desks
- •Chatterjee recommends transition times and a 3-4-5 breath before meals
- •A prayer's 5.5-second breathing rate appears across cultures, according to Italian researchers
Nasal Breathing for Athletic Performance
Responding to a question from his videographer, Chatterjee asks about athletics. Nestor explains that nasal breathing allows harder work at a lower heart rate, and Chatterjee shares how he uses nasal breathing as his running barometer.
- •Nasal breathing allows harder performance at a lower heart rate
- •Sanya Richards-Ross and John Douillard's cyclist research are cited as examples
- •Acclimating to nasal breathing during exercise can take weeks or months
- •Never work out harder than you can breathe correctly
- •Nestor compares the coming awareness of breathing to what happened with processed food
Wim Hof, Over-Breathing Practices and the Roots of Yoga
Chatterjee asks about practices that consciously over-breathe. Nestor clarifies that occasional mouth breathing is fine, explains how deliberate over-breathing and breath holds can help the nervous system, and says early yoga was only breathing and focusing.
- •A few hundred mouth breaths per day is fine; the problem is chronic habit
- •Conscious over-breathing and breath holds differ from unconscious dysfunction
- •Wim Hof Method practitioners report improvements in autoimmune conditions
- •Nestor says Wim Hof didn't invent the method but brought it to the masses
- •Early yoga had no standing poses, and vinyasa flow is about 100 years old
Freedivers, Fear and Closing Advice
Chatterjee asks whether freedivers had mental health conditions, and Nestor describes freediving as forced meditation. Chatterjee mentions the study of the woman without an amygdala, and Nestor closes with advice to try simple slow breathing and judge for yourself.
- •Many freedivers Nestor met had anxiety, depression or addiction issues
- •Freediving can't be done while panicked, so it works as forced meditation
- •Fear and anxiety can arise from physiology, such as CO2, not only external events
- •Nestor suggests measuring blood pressure before and after breathing six times a minute
- •Start small and give a practice about a week
