Dive into an intriguing exploration of the remarkable power of breath, from primitive healing practices to its immense potential in modern science!

Breath: The New Science of a Lost Art

A patient, middle-aged and visibly anxious, recently found himself at Stanford’s Department of Otolaryngology. Raised on a soft diet, his underdeveloped dental arches and narrow airways led to chronic nasal congestion. Years of orthodontic work worsened his breathing issues, escalating to sleep apnea. 

The patient was James Nestor, the author. Now, for an experiment, he’s about to spend ten days breathing solely through his mouth, sealed off from his nose with silicone plugs and surgical tape.

Dr. Jayakar Nayak, a nasal and sinus expert, guided an endoscope deep into his sinuses, revealing the intricate landscape within. Nayak’s research underscores the vital role of the nose, often undervalued in medicine, in orchestrating essential bodily functions.

Breathing through the mouth is a reality for many, often due to chronic nasal obstruction and the shrinking space in modern human skulls. This experiment, consisting of two phases, aims to demonstrate the detrimental effects of mouth breathing and the benefits of nasal breathing.

Joining the experiment is Anders Olsson, a respected breathing therapist from Sweden, who was initially hesitant but curious. Over the next ten days, both participants will live their daily lives while mouth breathing, with all activities monitored and data collected.

This journey into breathing’s impact began with a visit to Dr. Marianna Evans in Philadelphia, studying ancient skulls at the University of Pennsylvania. These ancient human skulls, unlike modern ones, had large jaws and wide nasal cavities, indicating better breathing and fewer respiratory issues. Modern skulls, in contrast, show signs of malocclusion and obstructed airways.

This shift likely started around 1.7 million years ago with our ancestors, Homo habilis, who began processing food. Cooking and mashing food led to smaller jaws and mouths but bigger brains. As human evolution progressed, these changes made breathing more difficult.

The Stanford experiment, now in its early stages, already shows alarming results. The patient’s snoring and sleep apnea have drastically worsened, highlighting the crucial role of nasal breathing. As he lies in bed, struggling to adapt to mouth breathing, he contemplates the evolution of human breathing and the challenges we face today. The next phase of the experiment will explore the potential improvements brought by nasal breathing and specialized techniques, offering hope for better respiratory health.

Can Stanford's Bold Experiment with Dr. Nayak and Olsson Unveil the Hidden Dangers of Mouth Breathing?

It's 8:15 a.m., and Olsson bursts into the flat of James Nestor, the author, with silicone plugs up his nose, dressed in cut-off sweatpants and an Abercrombie & Fitch sweatshirt. He looks gaunt and haunted, a shadow of his former self, as they hit the halfway point of their mouthbreathing experiment. 

They strap on their beeping and burping machines, recording physiological data that screams one thing: mouthbreathing is wrecking their health. Nestor's blood pressure has spiked, his heart rate variability has plummeted, and his mental clarity is in the gutter. Olsson's data mirrors Nestor's, and they feel awful.

After testing, Olsson leaves, and Nestor prepares breakfast: three eggs, half an avocado, German brown bread, and Lapsang tea. The final test, eating, is done alone. They meticulously record their blood sugar levels and step counts to assess how mouthbreathing and nasal breathing affect weight and metabolism.

Desperate for relief, they head to the gym for a bike ride. Olsson, who has researched the impact of nasal vs. mouth breathing on athletic performance, insists they pedal to their aerobic limits. He believes mouthbreathing saps performance and energy efficiency, a theory supported by Dr. John Douillard's studies from the 1990s. Douillard found that athletes who nasal breathed during intense exercise felt less fatigued and more invigorated.

As Nestor pedals on the stationary bike, mouthbreathing, he sweats profusely and struggles, covering only 6.44 miles in 30 minutes. Olsson takes his turn, and they head back to their home lab for more testing.

Decades before them, scientists like Egil P. Harvold explored mouthbreathing's effects. Harvold's experiments on monkeys showed that nasal obstruction led to facial deformities and narrowed airways, a chilling reflection of what happens to humans. Mouthbreathing begets more mouthbreathing, while nasal breathing promotes wider, healthier airways.

Patrick McKeown, a leading expert on nasal breathing, confirms the interconnectedness of their airways. Mouthbreathing during sleep exacerbates snoring and sleep apnea, contributing to a host of health issues. Nestor's own snoring has increased dramatically, and he's experiencing sleep apnea for the first time. Mouthbreathing is making him dumber and more dehydrated, disrupting his sleep and overall health.

But there's hope. Marianna Evans, an orthodontist, shows Nestor the transformation of her patient Gigi, who went from chronic respiratory issues to vibrant health through proper nasal breathing. Harvold's monkeys also recovered once their nasal passages were cleared, regaining their natural facial structure and health.

As Nestor lies in bed, struggling to sleep, he looks forward to the next day when the plugs come out. He hopes to reverse the damage and relearn to breathe like his ancestors.

Breathing Battle: The Shocking Health Effects of Mouthbreathing Unveiled

Dr. Nayak greeted Nestor with a blunt "You look like shit" as he examined his chaotic nasal cavity. Nestor had just completed ten days of mouthbreathing for an experiment, and his nose was a disaster. 

Removing the plugs and tape was supposed to be a moment of relief, but it brought just more discomfort. Only after several sinus rinses at home did Nestor finally take a full breath through his nose, experiencing a burst of vivid scents that felt like a Technicolor explosion in his head.

Breathing, Nestor realized, is our most intimate connection to the world. It’s not just about air; it’s about absorbing life itself. This experiment aimed to restore Nestor's health by returning to nasal breathing, a practice supported by ancient wisdom and modern science. For instance, the Tantric text Shiva Swarodaya described how our nostrils open and close in rhythm with the cosmos, a pattern confirmed by modern studies.

In 2004, Dr. Ananda Bhavanani tested these patterns and found that changes in nostril dominance correlated with the lunar cycle. The phenomenon of nasal cycles was first described in 1895 by Dr. Richard Kayser, who found that our nostrils alternately congest and decongest due to erectile tissue, the same tissue found in genitals. This tissue’s swelling and shrinking are influenced by our health and emotions.

Nasal breathing affects more than our respiratory system; it influences our heart rate, blood pressure, and even mental states. Right-nostril breathing activates the sympathetic nervous system, increasing alertness, while left-nostril breathing calms us by engaging the parasympathetic system. Researchers even helped a schizophrenic woman reduce hallucinations by teaching her to breathe through her "logical" right nostril.

The importance of nasal breathing was also championed by George Catlin in the 19th century. He observed that Native American tribes, who practiced strict nasal breathing from birth, enjoyed robust health, straight teeth, and strong physiques. Catlin himself cured his chronic respiratory issues by forcing himself to breathe through his nose.

For modern applications, mouth taping at night can help maintain nasal breathing, boosting nitric oxide levels and improving overall health. Nestor's own experiment with mouth tape led to dramatic improvements: his snoring disappeared, apnea events dropped to zero, and he finally experienced restful sleep.

As Nestor embraced these ancient and modern practices, he was reminded of Catlin’s parting words: “SHUT-YOUR-MOUTH.” Simple advice that could transform our health and well-being.

Can Nasal Breathing Techniques Inspired by Ancient Wisdom and Modern Science Transform Your Health?

Every morning at 9 am, after some testing with Olsson, Nestor rolls out a mat in his living room and works on the Five Tibetan Rites. These ancient stretches, passed down by Buddhist monks for 2,500 years, are believed to enhance lung capacity and extend life. The rites were introduced to the West by writer Peter Kelder, who learned them from an elderly British Colonel who had rejuvenated himself by practicing these rites in a Himalayan monastery.

Science backs this up. The Framingham Study, which tracked 5,200 subjects over two decades, found that lung capacity was the greatest indicator of lifespan. The larger the lungs, the longer the life. Another study by the University of Buffalo confirmed these findings. Yet, neither study addressed how to expand lung capacity—until now.

Katharina Schroth, a scoliosis patient from early 1900s Germany, developed "orthopedic breathing" to straighten her spine. By expanding her lungs and rib cage, she effectively cured herself of scoliosis. She went on to help hundreds of severe scoliosis patients do the same at her institute, despite skepticism from the medical community. Schroth's techniques were later recognized and awarded by the German government.

Modern science has also acknowledged the malleability of internal organs. Freedivers, for instance, have increased their lung capacity by 30-40% through specialized breathing techniques. Herbert Nitsch, a world record-holding freediver, has a lung capacity of 14 liters, double the average. Regular practices like walking or cycling can boost lung size by up to 15%.

Nestor visited Lynn Martin, a breathing expert in New York City, to learn more. Martin had worked with Carl Stough, a choir conductor who transformed the lives of emphysema patients by teaching them to exhale fully. Stough's methods, though unorthodox, showed that proper exhalation could vastly improve lung capacity and overall health. He even trained Olympic athletes, leading them to record-breaking performances at the 1968 Summer Olympics.

Despite the proven benefits, Stough's techniques are largely forgotten. Today, emphysema treatments focus on medications and supplemental oxygen, ignoring the potential of breathing exercises to expand lungs and improve health.

As Nestor left Martin's apartment, he realized that the secret to a longer, healthier life might just be in the breath we take—and more importantly, in the breath we let out.

Unlocking Longevity: Ancient Rituals and Modern Science Breathe New Life into Health

Olsson and Nestor sat across from each other at the dining room table, performing their daily ritual of testing pH levels, heart rates, and other vitals. This was the 45th time in two weeks. Their discussions often revolved around Olsson's obsession: carbon dioxide. Initially, Nestor was skeptical. Olsson claimed that carbon dioxide was more crucial than oxygen, essential for improving health, mental sharpness, and even longevity. Despite his doubts, Nestor flew to Sweden to understand his perspective.

Olsson’s journey began with his father's death from stress-related illnesses, motivating him to explore medical research. He sold his business, simplified his life, and dedicated himself to studying the science of breathing. His findings echoed those of early 20th-century scientists like Christian Bohr and Yandell Henderson, who discovered that carbon dioxide was vital for efficient oxygen delivery and overall health.

Breathing slowly, Olsson explained, wasn't just about relaxation. It helped balance oxygen and carbon dioxide levels, optimizing bodily functions. He demonstrated this in Nestor's living room with a pulse oximeter, showing how slow nasal breathing could maintain high oxygen levels while increasing carbon dioxide, lowering blood pressure, and heart rate.

Intrigued, Nestor adopted this method during workouts and saw significant improvements. His endurance increased as he breathed slower and more efficiently. This practice, known as resonant or coherent breathing, mirrors ancient prayer techniques found in various cultures, all benefiting from the same calming effect.

Research from the University of Pavia confirmed that slow breathing enhanced blood flow to the brain and optimized physiological functions. Doctors Patricia Gerbarg and Richard Brown successfully used this technique to treat anxiety, depression, and even ground-glass lungs in 9/11 survivors.

Slow breathing offered the benefits of meditation without the need for extended practice. It was an accessible, private, and powerful tool for improving health and well-being, proving that sometimes, less really is more.

Is Slow Breathing the Key to Health and Longevity According to Olsson's Research?

Few would dispute that our culture has become one of overeaters and overbreathers. From 1850 to 1960, the American mean body mass index (BMI) was between 20 and 22. Today, the average BMI is 29. 

Seventy percent of the U.S. population is considered overweight; one in three are obese. Similarly, our breathing rates now range between 12 and 20 breaths a minute, about twice as much as before. Just as people have been conditioned to consume too much food, they have been conditioned to breathe too much. But there’s a solution: breathe less.

Indian yogis, Tibetan Buddhists, and ancient Chinese doctors have long practiced techniques to reduce and calm breathing. Even samurai used breathing techniques to test a soldier’s readiness. Yet, breathing less is not the same as breathing slowly. The key is to practice fewer inhales and exhales in a smaller volume.

During the Stanford experiment, Nestor reaped the benefits of slowing his respiratory rate. His blood pressure dropped, his heart rate variability rose, and he had more energy. Olsson, Nestor's guide, emphasized the wonders of breathing way less, likening it to the respiratory equivalent of fasting. He discussed the potent benefits of occasionally willing the body to breathe way less, similar to fasting.

Konstantin Buteyko, a pulmonaut from Ukraine, discovered that overbreathing might be the cause of many chronic diseases. During his residency, he noticed that patients in the worst health all seemed to breathe too much. Buteyko himself suffered from severe high blood pressure and discovered that breathing less alleviated his symptoms. He developed a protocol called Voluntary Elimination of Deep Breathing and conducted extensive experiments that showed the healthiest patients breathed less.

Buteyko's methods influenced athletes like Emil Zátopek, who experimented with breath-restriction techniques and won multiple Olympic gold medals. Hypoventilation training, or breathing less, was later rediscovered by swim coach James Counsilman, leading the U.S. Men’s Swimming team to historic victories in the 1976 Olympics. Despite some studies questioning its efficacy, recent research by Dr. Xavier Woorons and others have shown that breathing less offers significant benefits, including increased endurance and improved cardiovascular function.

In Golden Gate Park, Olsson and Nestor practiced extreme breath control while jogging, aiming to increase their carbon dioxide levels and aerobic endurance. The exercise was challenging but highlighted the potential benefits of breathing less, including increased VO2 max, which boosts athletic stamina and longevity.

Asthma has become a global epidemic, with nearly 25 million Americans suffering from it. Asthma can be brought on by overbreathing, leading to more severe attacks. Learning to breathe less has shown dramatic improvements for many asthma sufferers. Dr. Alicia Meuret's research demonstrated that asthmatics who practiced breathing less experienced significantly fewer asthma attacks and better lung function.

Breathing less can correct the "system error" caused by overbreathing, improving overall health. Buteyko's methods have been effective in treating respiratory diseases and have helped many people breathe better and live healthier lives. Despite some resistance from the medical community, the benefits of breathing less are undeniable.

The optimal breathing rate is about 5.5 breaths per minute, or 5.5-second inhales and exhales. This is the perfect breath, and practicing this way for even a few minutes a day can benefit anyone, from asthmatics to Olympians. The key is to just keep breathing, less.

Breathe Less, Live More: The Ancient Secret to Modern Health

It’s the final day of the Stanford experiment, and Olsson and Nestor are exhausted yet exhilarated. For the last 19 days, they’ve been monitoring their health metrics like blood pressure and nitric oxide levels while practicing nasal breathing. 

The results have been astonishing: dramatic reductions in snoring and sleep apnea, lower blood pressure, and higher carbon dioxide levels approaching those of elite endurance athletes. All these improvements came from simply breathing through their noses instead of their mouths.

This experience sparked Nestor's quest to understand the lost art of breathing. It led him to investigate how the advent of farming and processed foods drastically altered human physiology. Ancient skulls reveal that our ancestors had wide, well-formed jaws and clear airways, but with the rise of soft, industrialized foods, our mouths shrank, our teeth became crooked, and our airways obstructed.

Nestor's journey took a surreal turn in the Paris Catacombs, where he examined skulls of people who lived through the early days of processed foods. Their narrow faces and deformed jaws were stark evidence of the changes wrought by industrialized diets. This exploration confirmed that the lack of chewing stress from soft foods was a significant factor in our modern breathing issues.

Orthodontic practices also played a role. Traditional methods involving tooth extractions and braces often made matters worse, making already small mouths smaller and obstructing airways further. Nestor met Dr. John Mew, a controversial figure in dentistry, who advocated for expanding the mouth to improve breathing. His methods, though initially ridiculed, are gaining acceptance.

Modern solutions include devices like Dr. Theodore Belfor’s Homeoblock, which stimulates bone growth in the face and expands the airways. After using one for a year, Nestor's own scans showed significant improvements in bone density and airway openness.

Ultimately, Nestor believes the key to better breathing lies in returning to our roots: proper oral posture, hard chewing, and nasal breathing. This simple yet profound shift can reverse much of the damage caused by centuries of dietary changes and poor orthodontic practices. It's a journey back to the basics, but one that can lead to a healthier, more breathable future.

Can Nasal Breathing and Ancestral Diets Unlock the Secrets to Elite Health?

The morning after their supposed "last" supper, Olsson and Nestor headed to Stanford for a final check-up with Dr. Nayak. After a series of tests, they were free to breathe normally again. Olsson returned to Sweden, while Nestor continued his exploration into the extreme limits of breath.

These advanced techniques, which Nestor calls Breathing+, are not for everyone. They require time, effort, and can be uncomfortable. They can push the body into states like respiratory acidosis and sympathetic nervous system overload, which are usually harmful but can be transformative when practiced correctly. These methods date back thousands of years and have been rediscovered across different cultures.

One such technique emerged on Civil War battlefields. Soldiers with no apparent physical injuries suffered from symptoms like anxiety, paranoia, and breathlessness. Dr. Jacob Mendez Da Costa identified this as Irritable Heart Syndrome. The symptoms would come and go, often disappearing with rest and relaxation, only to return under stress.

Years later, Nestor found himself practicing a similar technique, Inner Fire Meditation, in a public park under the guidance of Chuck McGee III. This method, known as Tummo, was developed by Tibetan Buddhists and involves intense breathing to generate internal heat. While practicing, Nestor felt anxious and paranoid, reminiscent of Da Costa's soldiers, but he knew this was conscious stress, not something happening to him.

Breathing affects the autonomic nervous system, which controls our organs. Slow, deep breaths activate the parasympathetic system, promoting relaxation, while quick, shallow breaths trigger the sympathetic system, preparing us for action. Despite the discomfort, these breathing techniques can offer profound benefits. They have been used by athletes, soldiers, and even ordinary people to manage stress and improve health.

The history of Tummo is fascinating. It was discovered by Naropa, an Indian man who used it to survive in the Himalayas. The technique remained hidden in Tibetan monasteries for centuries until Alexandra David-Néel, a Belgian-French explorer, brought it to the West in the early 1900s. She used Tummo to endure harsh conditions and live a long, healthy life.

Modern practitioners like Wim Hof have popularized Tummo through daredevil stunts. Hof's ability to control his immune response and withstand extreme conditions has been scientifically validated. His method, which combines heavy breathing with cold exposure, has helped many people manage stress and improve their health.

Breathing techniques like Holotropic Breathwork, developed by Stanislav Grof, offer another dimension. This practice involves intense breathing to access subconscious thoughts and emotions, leading to psychological breakthroughs. Nestor experienced this firsthand during a session, where participants had profound emotional releases and mystical visions.

These breathing methods, whether for physical or psychological benefits, demonstrate the power of breath. They show that with conscious effort, we can influence our autonomic nervous system, manage stress, and improve our well-being.

Unlock the Power of Breath: From Tummo to Wim Hof and Beyond

In 1968, Dr. Arthur Kling ventured to Cayo Santiago, Puerto Rico, for a controversial experiment involving wild monkeys. By removing their amygdalae, he stripped them of fear, leading to their untimely deaths. Years later, Kling's work found a human parallel in S.M., a woman with Urbach-Wiethe disease that destroyed her amygdalae, making her fearless and naive to danger.

In 2006, Dr. Justin Feinstein met S.M. while researching anxieties, discovering that her condition could be replicated using carbon dioxide inhalation. Feinstein's experiment revealed that a single breath of carbon dioxide triggered a fear response in S.M. and others with similar conditions, challenging the belief that the amygdalae are the sole fear centers in the brain.

The deeper implication lies in the central chemoreceptors at the brain stem, which regulate our breath based on carbon dioxide levels. This ancient mechanism, shared across species, can trigger intense fear when disrupted. Feinstein's research suggests that managing carbon dioxide levels through controlled breathing could revolutionize anxiety treatment.

This connection to breath control isn't new. Ancient practices in India and China utilized breath-holding techniques for health benefits. However, modern distractions and unconscious breath-holding, like "email apnea," harm our health. Conscious breath control, contrastingly, offers potential healing.

Feinstein's current work at the Laureate Institute for Brain Research involves using carbon dioxide therapy to treat anxiety. By safely exposing patients to carbon dioxide, he aims to reset their chemoreceptors, offering a modern twist on ancient practices for those too anxious to hold their breath.

The broader narrative underscores the intertwined nature of breath, fear, and survival, suggesting that mastering breath control could unlock new frontiers in mental health resilience.

Can Ancient Breath Control Practices and Modern Science Together Cure Anxiety?

Every day, 800,000 commuters flood São Paulo's bustling Paulista Avenue. Amidst the chaos of honking cars, noisy pedestrians, and neglected newsstands selling everything from Cosmopolitan to Nietzsche, Nestor set out to meet Luíz DeRose, a yoga expert who explores the ancient roots of breathing practices. 

DeRose's yoga predates the modern, aerobic exercise society has come to know. It focuses on breath and thought, tracing back to a time when breathing was seen as a powerful technology.

Nestor's curiosity about breathing techniques like Tummo and Holotropic Breathwork led him to DeRose. How do practitioners like Wim Hof and monks in the Bön and Buddhist traditions endure extreme cold? How does intense overbreathing induce surreal, hallucinatory states? These questions have puzzled researchers for decades, but ancient texts might hold the answers.

DeRose, an author of 30 books on ancient yoga, is an esteemed figure in Brazil, decorated with numerous honors. He believes in the transformative power of prana, or life force, a concept that has parallels in many ancient cultures, from Chinese ch’i to Japanese ki. Prana flows through us, and its blockage can lead to illness. Techniques to maintain this flow, like acupuncture and yoga, have existed for millennia.

A breakthrough moment in understanding prana came in 1970 when Swami Rama demonstrated his control over his bodily functions at the Menninger Clinic in Kansas. He could alter his heart rate, brain waves, and even body temperature at will, showcasing the power of breath control. Rama's abilities, though extraordinary to Western observers, were standard practices among Indian yogis for generations.

Albert Szent-Györgyi, a Hungarian scientist, offered a scientific perspective on prana. He suggested that the energy driving all life comes from the excitability of electrons within our cells. The more oxygen we consume, the more electron excitability we gain, keeping us alive and healthy. This premise aligns with prana's ancient concept, emphasizing that breathing deeply and correctly can infuse our bodies with vital energy.

DeRose's teachings echo these ancient practices, emphasizing patience and gradual mastery of breathing techniques. He recalls his journey through India in the 1970s, where he learned yoga focusing on long-held postures and deep breathing. Unlike modern yoga, which has evolved into a form of aerobic exercise, ancient yoga was about stillness and building prana.

As Nestor practiced breathing with DeRose's student, Pinheiro, he felt the familiar sensations of warmth and calm that ancient practitioners must have experienced. These techniques, from Tummo to Sudarshan Kriya, offer profound benefits, helping us sleep better, run faster, and live longer.

Breathing, a seemingly simple act, holds immense power. It can balance our bodies, improve our health, and connect us to the ancient wisdom of our ancestors. Whether through modern science or ancient practice, the magic of breath continues to unfold with every inhale and exhale.

Unveiling the Ancient Power of Breath: A Journey with Luíz DeRose

Chronic nasal obstruction and the shrinking space in modern human skulls have made mouth breathing a reality for many. A recent experiment was conducted to demonstrate the detrimental effects of mouth breathing and the benefits of nasal breathing. 

The results of the experiment, which involved the participants solely breathing through their mouths, revealed alarming health repercussions. The participants experienced spikes in blood pressure, decreased heart rate variability, and impaired mental clarity. The experiment also showed that mouth breathing negatively affected sleep, leading to increased snoring and sleep apnea. 

The examination of ancient human skulls revealed that our ancestors had larger jaws and wider nasal cavities, indicating better breathing and fewer respiratory issues. Changes in human evolution, specifically the shift to processing food, have led to smaller jaws and mouths but bigger brains, making breathing more difficult. 

Research has shown that nasal breathing plays a crucial role in orchestrating essential bodily functions and improving overall health. Findings suggest that nasal breathing can lead to improvements in heart rate, blood pressure, and even mental states. Breathing through the right nostril, for instance, activates the sympathetic nervous system and increases alertness, while left-nostril breathing induces calmness by engaging the parasympathetic system. 

Ancient practices from India, China, and Japan have long used techniques to reduce and calm breathing, highlighting the significance of breathing less, not just slowly. Breathing less, much like fasting, can stimulate numerous health benefits, such as increased endurance and improved cardiovascular function. Studies have also shown that asthmatics who practiced breathing less experienced significantly fewer asthma attacks and better lung function. 

Advanced breathing techniques, pushing the body into states like respiratory acidosis and sympathetic nervous system overload, have also been explored. These methods, though uncomfortable, can be transformative when practiced correctly and can influence our autonomic nervous system, manage stress, and improve health and well-being.

Breathing techniques that involve intense breathing to generate internal heat or to access subconscious thoughts and emotions can offer profound physical and psychological benefits. Practitioners have used these techniques to manage stress, improve health, and even control immune responses. 

The exploration of ancient breathing practices and modern scientific research underscores the intertwined nature of breath, fear, and survival. Mastering breath control could unlock new frontiers in mental health resilience and suggest that the secret to a longer, healthier life might just be in the breath we take—and more importantly, in the breath we let out.
