Breath James Nestor Quotes

the greatest indicator of life span wasn’t genetics, diet, or the amount of daily exercise, as many had suspected. It was lung capacity.

Prayer heals, especially when it’s practiced at 5.5 breaths a minute.

The perfect breath is this: Breathe in for about 5.5 seconds, then exhale for 5.5 seconds. That’s 5.5 breaths a minute for a total of about 5.5 liters of air.

A last word on slow breathing. It goes by another name: prayer. When Buddhist monks chant their most popular mantra, Om Mani Padme Hum, each spoken phrase lasts six seconds, with six seconds to inhale before the chant starts again. The traditional chant of Om, the “sacred sound of the universe” used in Jainism and other traditions, takes six seconds to sing, with a pause of about six seconds to inhale.

Breathe normally through the nose and hum, any song or sound. Practice for at least five minutes a day, more if possible.

Left-nostril breathing shifts blood flow to the opposite side of the prefrontal cortex, the right area that plays a role in creative thought, emotions, formation of mental abstractions, and negative emotions.

Expression is the opposite of depression! Go for it!

It turns out that when breathing at a normal rate, our lungs will absorb only about a quarter of the available oxygen in the air. The majority of that oxygen is exhaled back out. By taking longer breaths, we allow our lungs to soak up more in fewer breaths.

The fix is easy: breathe less. But that’s harder than it sounds. We’ve become conditioned to breathe too much, just as we’ve been conditioned to eat too much. With some effort and training, however, breathing less can become an unconscious habit.

Each breath we draw in should take about three seconds, and each breath out should take four. We’ll then continue the same short inhales while lengthening the exhales to a five, six, and seven count as the run progresses.

Mouthbreathing, it turns out, changes the physical body and transforms airways, all for the worse. Inhaling air through the mouth decreases pressure, which causes the soft tissues in the back of the mouth to become loose and flex inward, creating less space and making breathing more difficult. Mouthbreathing begets more mouthbreathing.

Smell is life’s oldest sense. Standing here alone, nostrils flaring, it occurs to me that breathing is so much more than just getting air into our bodies. It’s the most intimate connection to our surroundings.

the most efficient breathing rhythm occurred when both the length of respirations and total breaths per minute were locked in to a spooky symmetry: 5.5-second inhales followed by 5.5-second exhales, which works out almost exactly to 5.5 breaths a minute. This was the same pattern of the rosary. The results were profound, even when practiced for just five to ten minutes a day. “I have seen patients transformed by adopting regular breathing practices,” said Brown.

Some cultures ate nothing but meat, while others were mostly vegetarian. Some relied primarily on homemade cheese; others consumed no dairy at all. Their teeth were almost always perfect; their mouths were exceptionally wide, nasal apertures broad. They suffered few, if any, cavities and little dental disease.

he noticed that patients in the worst health all seemed to breathe far too much. The more they breathed, the worse off they were, especially those with hypertension

50 percent of kids with ADHD were shown to no longer have symptoms after having their adenoids and tonsils removed.

More than sixty years of research on living systems has convinced me that our body is much more nearly perfect than the endless list of ailments suggests,” wrote Nobel laureate Albert Szent-Györgyi. “Its shortcomings are due less to its inborn imperfections than to our abusing it.

For every ten pounds of fat lost in our bodies, eight and a half pounds of it comes out through the lungs; most of it is carbon dioxide mixed with a bit of water vapor. The rest is sweated or urinated out. This is a fact that most doctors, nutritionists, and other medical professionals have historically gotten wrong. The lungs are the weight-regulating system of the body.

The missing pillar in health is breath. It all starts there.

What if overbreathing wasn’t the result of hypertension and headaches but the cause? Buteyko wondered.

The stretches, called the Five Tibetan Rites, came to the Western world, and to me, by way of writer Peter Kelder, who was known as a lover of “books and libraries, words and poetry.

right nostril is a gas pedal. When you’re inhaling primarily through this channel, circulation speeds up, your body gets hotter, and cortisol levels, blood pressure, and heart rate all increase. This happens because breathing through the right side of the nose activates the sympathetic nervous system, the “fight or flight” mechanism that puts the body in a more elevated state of alertness and readiness. Breathing through the right nostril will also feed more blood to the opposite hemisphere of the brain, specifically to the prefrontal cortex, which has been associated with logical decisions, language, and computing. Inhaling through the left nostril has the opposite effect: it works as a kind of brake system to the right nostril’s accelerator. The left nostril is more deeply connected to the parasympathetic nervous system, the rest-and-relax side that lowers blood pressure, cools the body, and reduces anxiety. Left-nostril breathing shifts blood flow to the opposite side of the prefrontal cortex, to the area that influences creative thought and plays a role in the formation of mental abstractions and the production of negative emotions.

When the nasal cavity gets congested, airflow decreases and bacteria flourish. These bacteria replicate and can lead to infections and colds and more congestion. Congestion begets congestion, which gives us no other option but to habitually breathe from the mouth.

This measurement of highest oxygen consumption, called VO2 max, is the best gauge of cardiorespiratory fitness. Training the body to breathe less actually increases VO2 max, which can not only boost athletic stamina but also help us live longer and healthier lives.

After much trial and error, I settled on 3M Nexcare Durapore “durable cloth” tape, an all-purpose surgical tape with a gentle adhesive. It was comfortable, had no chemical scent, and didn’t leave residue.

Human blood has a chemical composition startlingly similar to seawater. An infant will reflexively breaststroke when placed underwater and can comfortably hold his breath for about forty seconds, longer than many adults. We lose this ability only when we learn how to walk.

Ninety percent of the obstruction in the airway occurs around the tongue, soft palate, and tissues around the mouth. The smaller the mouth is, the more the tongue, uvula, and other tissues can obstruct airflow.

Once a day, they were to lie down, take a brief inhale, and then exhale to a count of 6. As they progressed, they could inhale to a count of 4 and exhale to 8, with the goal of reaching a half-minute exhale after six months of practice. Upon reaching this 30 count,

Hypoventilation training

The sa ta na ma chant, one of the best-known techniques in Kundalini yoga, also takes six seconds to vocalize, followed by six seconds to inhale.

The takeaway is that hypoventilation works. It helps train the body to do more with less. But that doesn’t mean it’s pleasant.

the nose is the silent warrior: the gatekeeper of our bodies, pharmacist to our minds, and weather vane to our emotions.

Inhaling through the left nostril has the opposite effect: it works as a kind of brake system to the right nostril’s accelerator. The left nostril is more deeply connected to the parasympathetic nervous system, the rest-and-relax side that lowers blood pressure, cools the body, and reduces anxiety.

All of them claimed to have gained a boost in performance and blunted the symptoms of respiratory problems, simply by decreasing the volume of air in their lungs and increasing the carbon dioxide in their bodies.

* One thing that every medical or freelance pulmonaut I’ve talked to over the past several years has agreed on is that, just as we’ve become a culture of overeaters, we’ve also become a culture of overbreathers. Most of us breathe too much, and up to a quarter of the modern population suffers from more serious chronic overbreathing.

In colder climates, our noses would grow narrower and longer to more efficiently heat up air before it entered our lungs; our skin would grow lighter to take in more sunshine for production of vitamin D. In sunny and warm environments, we adapted wider and flatter noses, which were more efficient at inhaling hot and humid air; our skin would grow darker to protect us from the sun. Along the way, the larynx would descend in the throat to accommodate another adaptation: vocal communication.

Our bodies operate most efficiently in a state of balance, pivoting between action and relaxation, daydreaming and reasoned thought. This balance is influenced by the nasal cycle, and may even be controlled by it. It’s a balance that can also be gamed. There’s a yoga practice dedicated to manipulating the body’s functions with forced breathing through the nostrils. It’s called nadi shodhana—in Sanskrit, nadi means “channel” and shodhana means “purification”—or, more commonly, alternate nostril breathing. —

the best way to prevent many chronic health problems, improve athletic performance, and extend longevity was to focus on how we breathed, specifically to balance oxygen and carbon dioxide levels in the body. To do this, we’d need to learn how to inhale and exhale slowly.

Packman explained that overbreathing can have other, deeper effects on the body beyond just lung function and constricted airways. When we breathe too much, we expel too much carbon dioxide, and our blood pH rises to become more alkaline; when we breathe slower and hold in more carbon dioxide, pH lowers and blood becomes more acidic. Almost all cellular functions in the body take place at a blood pH of 7.4, our sweet spot between alkaline and acid.

The right nostril is a gas pedal. When you’re inhaling primarily through this channel, circulation speeds up, your body gets hotter, and cortisol levels, blood pressure, and heart rate all increase.

the empty nose stories spooked me enough to explore other options before I ever went under the knife to fix my obstructed breathing.

Ancient yoga, and its focus on prana, sitting, and breathing, has turned into a form of aerobic exercise.

And they all likely benefited from the same calming effect.

Onward and inward, another wiggle and another yank, and I was in the thick of it

When sitting or standing, the spine should form a J-shape—perfectly straight until it reaches the small of the back, where it naturally curves outward.

and I will know how the air that enters your lungs affects every moment of your life and how to harness it to its full potential until your final breath.

The Bhagavad Gita, a Hindu spiritual text written around 2,000 years ago, translated the breathing practice of pranayama to mean “trance induced by stopping all breathing.

In school, when I was young, teachers walked around the classroom, man, and pop-pop-pop.” He smacks the back of his own head for emphasis. “You’re breathing from your mouth, you get pop,” he says. Mouthbreathing leads to sickness and is disrespectful, he told me, which is why he and everyone else he grew up with in Puebla, Mexico, learned to breathe through the nose.

This is because neither adenoid/tonsil removal nor CPAP nor other procedures provide a satisfying long-term solution, because none deals with the core issue: a mouth that is too small for the face.

The key to optimum breathing, and all the health, endurance, and longevity benefits that come with it, is to practice fewer inhales and exhales in a smaller volume. To breathe, but to breathe less.

Breathing just 20 percent, or even 10 percent more than the body’s needs could overwork our systems. Eventually, they’d weaken and falter. Was breathing too much making people sick, and keeping them that way?

What stops the lungs from expanding is the musculature around the ribs, chest, and back. Through stretching and breathing exercises, freedivers develop up to 75 percent more lung capacity than the average person.

After a few months, mewers have claimed their mouths expanded, jaws became more defined, sleep apnea symptoms lessened, and breathing became easier. Mike’s own instructional video on mewing has been viewed a million times.

The nose tends to work in the same way. Sprays, rinses, and allergy medications can help quickly clear minor congestion, but for more serious chronic obstruction, we’ll need a surgeon to plumb the path. I heard this analogy a lot.

But the changes triggered by the rapid industrialization of farmed foods were severely damaging. Within just a few generations of eating this stuff, modern humans became the worst breathers in Homo history, the worst breathers in the animal kingdom.

Over his career, Buteyko would be censured by medical critics; he’d be physically attacked and, at one point, have his laboratory torn up. But he pressed on. By the 1980s, he had published more than 50 scientific papers and the Soviet Ministry of Health had

If surgeons drill out or remove too much tissue, especially the turbinates, the nose can’t effectively filter, humidify, clean, or even sense inhaled air. For this small and unfortunate group of patients, each breath comes in too quickly, a hideous condition called empty nose syndrome.

warms breath to your body temperature while simultaneously filtering out particles and pollutants. All these invaders could cause infection and irritation if they got into the lungs; the mucus is the body’s “first line of defense.” It’s constantly on the move, sweeping along at a rate of about half an inch every minute, more than 60 feet per day. Like a giant conveyor belt, it collects inhaled debris in the nose, then moves all the junk down the throat and into the stomach, where it’s sterilized by stomach acid, delivered to the intestines, and sent out of your body.

Over the years, this style of breath restriction has been given many names—hypoventilation, hypoxic training, Buteyko technique, and the pointlessly technical “normobaric hypoxia training.” The outcomes were the same: a profound boost in performance.* Not just for elite athletes, but for everyone.

The perfect breath is this: Breathe in for about 5.5 seconds, then exhale for 5.5 seconds. That’s 5.5 breaths a minute for a total of about 5.5 liters of air. You can practice this perfect breathing for a few minutes, or a few hours. There is no such thing as having too much peak efficiency in your body.

The point of this exercise isn’t to inflict unnecessary pain. It’s to get the body comfortable with higher levels of carbon dioxide, so that we’ll unconsciously breathe less during our resting hours and the next time we work out. So that we’ll release more oxygen, increase our endurance, and better support all the functions in our bodies.

Lie down every day, pacify your mind, cut off thoughts and block the breath. Close your fists, inhale through your nose, and exhale through your mouth. Do not let the breathing be audible. Let it be most subtle and fine. When the breath is full, block it. The blocking (of the breath) will make the soles of your feet perspire. Count one hundred times “one and two.” After blocking the breath to the extreme, exhale it subtly. Inhale a little more and block (the breath) again. If (you feel) hot, exhale with “Ho.” If (you feel) cold, blow the breath out and exhale it with (the sound) “Ch’ui.” If you can breathe (like this) and count to one thousand (when blocking), then you will need neither grains nor medicine.

People “play dead,” too, because we share the same mechanisms in the primitive part of our brain stem. We call it fainting. Our tendency to faint is controlled by the vagal system, specifically how sensitive we are to perceived danger. Some people are so anxious and oversensitive that their vagus nerves will cause them to faint at the smallest things, like seeing a spider, hearing bad news, or looking at blood.

After several rounds of deep breaths to open my rib cage, Martin asked me to start counting from one to ten over and over with every exhale. “1, 2, 3, 4, 5, 6, 7, 8, 9, 10; 1, 2, 3, 4, 5, 6, 7, 8, 9, 10—then keep repeating it,” she said. At the end of the exhale, when I was so out of breath I couldn’t vocalize anymore, I was to keep counting, but to do so silently, letting my voice trail down into a “sub-whisper.

Eventually I realized that all I or anyone really needed was a postage-stamp-size piece of tape at the center of the lips—a Charlie Chaplin mustache moved down an inch. That’s it. This approach felt less claustrophobic and allowed a little space on the sides of the mouth if I needed to cough or talk. After much trial and error, I settled on 3M Nexcare Durapore “durable cloth” tape, an all-purpose surgical tape with a gentle adhesive.

In a single breath, more molecules of air will pass through your nose than all the grains of sand on all the world’s beaches—trillions and trillions of them. These little bits of air come from a few feet or several yards away. As they make their way toward you, they’ll twist and spool like the stars in a van Gogh sky, and they’ll keep twisting and spooling and scrolling as they pass into you, traveling at a clip of about five miles per hour.

Balloon sinuplasty, as it’s commonly called, creates more space for mucus and infection to pass out, and air and mucus to pass in. In one unpublished case-control study, Nayak found that, of the 28 selected sinusitis patients who received the procedure, 23 needed no other treatment. Sometimes the nostrils are the problem, not the sinuses. Nostrils that are too small or that collapse too easily during an inhale can inhibit the free flow of air and contribute to breathing problems. This condition is so common that researchers have an official name for it, “nasal valve collapse,” and an official measurement, called the Cottle’s maneuver. It involves placing an index finger on the side of one or both nostrils and gently pulling each cheek outward, lightly spreading the nostrils open. If doing this improves the ease of nasal inhales, there’s a chance that the nostrils are too small or thin.

During that ride, I started playing around with my breathing. I tried to inhale and exhale slower and slower, from my usual exercising rate of 20 breaths a minute to just six. I immediately felt a sense of air hunger and claustrophobia. After a minute or so I looked down at the pulse oximeter to see how much oxygen I was losing, how starved my body had become. But my oxygen hadn’t decreased with these very slow breaths, as I or anyone else might expect. My levels rose. •

This is what I learned at the end of this long and very strange trip through the causes and cures of airway obstruction. That our noses and mouths are not predetermined at birth, childhood, or even in adulthood. We can reverse the clock on much of the damage that’s been done in the past few hundred years by force of will, with nothing more than proper posture, hard chewing, and perhaps some mewing. And with the obstruction out of the way, we can finally get back to breathing.

Scuba divers can make it to three hundred feet breathing mixed gases, but it takes years of training and is a logistical nightmare. The danger isn’t going down—although that certainly is dangerous—it’s coming back up. For a scuba diver, a one-hour plunge at two hundred feet breathing regular compressed air would require a ten-hour ascent to purge the deadly levels of nitrogen gas in the blood that accumulate on the way down. A three-hundred-foot ascent on compressed air would most likely kill you.

Decongest the Nose Sit up straight and exhale a soft breath, then pinch both nostrils shut. Try to keep your mind off the breathholding; shake your head up and down or side to side; go for a quick walk, or jump and run. Once you feel a very potent sense of air hunger, take a very slow and controlled breath in through the nose. (If the nose is still congested, breathe softly through the mouth with pursed lips.) Continue this calm, controlled breathing for at least 30 seconds to 1 minute. Repeat all these steps six times.

Then there were the ancient Hindu hand and tongue poses called mudras. A technique called khechari, intended to help boost physical and spiritual health and overcome disease, involves placing the tongue above the soft palate so that it’s pointed toward the nasal cavity. The deep, slow breaths taken during this khechari each take six seconds. Japanese, African, Hawaiian, Native American, Buddhist, Taoist, Christian—these cultures and religions all had somehow developed the same prayer techniques, requiring the same breathing patterns.

Along with maintaining the correct oral posture, Mike recommended a series of tongue-thrusting exercises, which he says can train us out of the “death pose” and make breathing easier. The tongue is a powerful muscle. If its force is directed at the teeth, it can throw them out of alignment; if it’s directed at the roof of the mouth, Mike believed it might help expand the upper palate of the mouth and open up the airways. The exercise, which Mike’s hordes of social media fans call “mewing,” has been popularly adopted as “a new health craze.

Breathhold Walking Anders Olsson uses this technique to increase carbon dioxide and, thus, increase circulation in his body. It’s not much fun, but the benefits, Olsson told me, are many. Go to a grassy park, beach, or anywhere else where the ground is soft. Exhale all the breath, then walk slowly, counting each step. Once you feel a powerful sense of air hunger, stop counting and take a few very calm breaths through the nose while still walking. Breathe normally for at least a minute, then repeat the sequence. The more you practice this technique, the higher the count. Olsson’s record is 130 steps; mine is about a third of that. 4-7-8 Breathing This technique, made famous by Dr. Andrew Weil, places the body into a state of deep relaxation. I use it on long flights to help fall asleep. Take a breath in, then exhale through your mouth with a whoosh sound. Close the mouth and inhale quietly through your nose to a mental count of four. Hold for a count of seven. Exhale completely through your mouth, with a whoosh, to the count of eight. Repeat this cycle for at least four breaths.

Many people with this condition receive minimally invasive surgery, or use adhesive strips called Breathe Right or nasal dilator cones. If these simpler approaches fail, the drills come out. About three-quarters of modern humans have a deviated septum clearly visible to the naked eye, which means the bone and cartilage that separate the right and left airways of the nose are off center. Along with that, 50 percent of us have chronically inflamed turbinates; the erectile tissue lining our sinuses is too puffed up for us to breathe comfortably through our noses.

Dr. Mark Burhenne had been studying the links between mouthbreathing and sleep for decades, and had written a book on the subject. He told me that mouthbreathing contributed to periodontal disease and bad breath, and was the number one cause of cavities, even more damaging than sugar consumption, bad diet, or poor hygiene. (This belief had been echoed by other dentists for a hundred years, and was endorsed by Catlin too.) Burhenne also found that mouthbreathing was both a cause of and a contributor to snoring and sleep apnea. He recommended his patients tape their mouths shut at night.

cause of cavities, even more damaging than sugar consumption, bad diet, or poor hygiene. (This belief had been echoed by other dentists for a hundred years, and was endorsed by Catlin too.) Burhenne also found that mouthbreathing was both a cause of and a contributor to snoring and sleep apnea. He recommended his patients tape their mouths shut at night. “The health benefits of nose breathing are undeniable,” he told me. One of the many benefits is that the sinuses release a huge boost of nitric oxide, a molecule that plays an essential role in increasing circulation and delivering oxygen into cells. Immune function, weight, circulation, mood, and sexual function can all be heavily influenced by the amount of nitric oxide in the body. (The popular erectile dysfunction drug sildenafil, known by the commercial name Viagra, works by releasing nitric oxide into the bloodstream, which opens the capillaries in the genitals and elsewhere.) Nasal breathing alone can boost nitric oxide sixfold, which is one of the reasons we can absorb about 18 percent more oxygen than by just breathing through the mouth. Mouth taping, Burhenne said, helped a five-year-old patient of his overcome ADHD, a condition directly attributed to breathing difficulties during sleep. It helped Burhenne and his wife cure their own snoring and breathing problems. Hundreds of other patients reported similar benefits. The whole thing seemed a little sketchy until Ann Kearney, a doctor of speech-language pathology at the Stanford Voice and Swallowing Center, told me the same. Kearney helped rehabilitate patients who had swallowing and breathing disorders. She swore by mouth taping. Kearney herself had spent years as a mouthbreather due to chronic congestion. She visited an ear, nose, and throat specialist and discovered that her nasal cavities were blocked with tissue. The specialist advised that the only way to open her nose was through surgery or medications. She tried mouth taping instead. “The first night, I lasted five minutes before I ripped it off,” she told me. On the second night, she was able to tolerate the tape for ten minutes. A couple of days later, she slept through the night. Within six weeks, her nose opened up. “It’s a classic example of use it or lose it,” Kearney said. To prove her claim, she examined the noses of 50 patients who had undergone laryngectomies, a procedure in which a breathing hole is cut into the throat. Within two months to two years, every patient was suffering from complete nasal obstruction. Like other parts of the body, the nasal cavity responds to whatever inputs it receives. When the nose is denied regular use, it will atrophy. This is what happened to Kearney and many of her patients, and to so much of the general population. Snoring and sleep apnea often follow.

The nose is crucial because it clears air, heats it, and moistens it for easier absorption. Most of us know this. But what so many people never consider is the nose’s unexpected role in problems like erectile dysfunction. Or how it can trigger a cavalcade of hormones and chemicals that lower blood pressure and ease digestion. How it responds to the stages of a woman’s menstrual cycle. How it regulates our heart rate, opens the vessels in our toes, and stores memories. How the density of your nasal hairs helps determine whether you’ll suffer from asthma. Few of us ever consider how the nostrils of every living person pulse to their own rhythm, opening and closing like a flower in response to our moods, mental states, and perhaps even the sun and the moon.

Then, decades later, in the 1970s, a hard-assed U.S. swim coach named James Counsilman rediscovered it. Counsilman was notorious for his “hurt, pain, and agony”–based training techniques, and hypoventilation fit right in. Competitive swimmers usually take two or three strokes before they flip their heads to the side and inhale. Counsilman trained his team to hold their breath for as many as nine strokes. He believed that, over time, the swimmers would utilize oxygen more efficiently and swim faster. In a sense, it was Buteyko’s Voluntary Elimination of Deep Breathing and Zátopek hypoventilation—underwater. Counsilman used it to train the U.S. Men’s Swimming team for the Montreal Olympics. They won 13 gold medals, 14 silver, and 7 bronze, and they set world records in 11 events. It was the greatest performance by a U.S. Olympic swim team in history. Hypoventilation training fell back into obscurity after several studies in the 1980s and 1990s argued that it had little to no impact on performance and endurance. Whatever these athletes were gaining, the researchers reported, must have been based on a strong placebo effect. In the early 2000s, Dr. Xavier Woorons, a French physiologist at Paris 13 University, found a flaw in these studies. The scientists critical of the technique had measured it all wrong. They’d been looking at athletes holding their breath with full lungs, and all that extra air in the lungs made it difficult for the athletes to enter into a deep state of hypoventilation. Woorons repeated the tests, but this time subjects practiced the half-full technique, which is how Buteyko trained his patients, and likely how Counsilman trained his swimmers. Breathing less offered huge benefits. If athletes kept at it for several weeks, their muscles adapted to tolerate more lactate accumulation, which allowed their bodies to pull more energy during states of heavy anaerobic stress, and, as a result, train harder and longer. Other reports showed hypoventilation training provided a boost in red blood cells, allowing athletes to carry more oxygen and produce more energy with each breath. Breathing way less delivered the benefits of high-altitude training at 6,500 feet, but it could be used at sea level, or anywhere. Over the years, this style of breath restriction has been given many names—hypoventilation, hypoxic training, Buteyko technique, and the pointlessly technical “normobaric hypoxia training.” The outcomes were the same: a profound boost in performance.* Not just for elite athletes, but for everyone. Just a few weeks of the training significantly increased endurance, reduced more “trunk fat,” improved cardiovascular function, and boosted muscle mass compared to normal-breathing exercise. This list goes on. The takeaway is that hypoventilation works. It helps train the body to do more with less. But that doesn’t mean it’s pleasant.

Noses get erections.

To some researchers, it’s no coincidence that eight of the top ten most common cancers affect organs cut off from normal blood flow during extended states of stress.

Here’s the information: To practice Wim Hof’s breathing method, start by finding a quiet place and lying flat on your back with a pillow under your head. Relax the shoulders, chest, and legs. Take a very deep breath into the pit of your stomach and let it back out just as quickly. Keep breathing this way for 30 cycles. If possible, breathe through the nose; if the nose feels obstructed, try pursed lips. Each breath should look like a wave, with the inhale inflating the stomach, then the chest. You should exhale all the air out in the same order. At the end of 30 breaths, exhale to the natural conclusion, leaving about a quarter of the air left in the lungs, then hold that breath for as long as possible. Once you’ve reached your breathhold limit, take one huge inhale and hold it another 15 seconds. Very gently, move that fresh breath of air around the chest and to the shoulders, then exhale and start the heavy breathing again. Repeat the whole pattern three or four rounds and add in some cold exposure (cold shower, ice bath, naked snow angels) a few times a week. This

I do not want to,” he declared. “But I am curious.

Nature seeks homeostasis and balance,” Belfor told me on the phone in one of our dozens of conversations since we first met. “You were out of balance. Just look at the scans. Nature corrected you by adding a tremendous amount of bone to your face—the proof is in the pudding.

Five Tibetan Rites,

Finding the best heart rate for exercise is easy: subtract your age from 180. The result is the maximum your body can withstand to stay in the aerobic state. Long bouts of training and exercise can happen below this rate but never above it, otherwise the body will risk going too deep into the anaerobic zone for too long. Instead of feeling invigorated and strong after a workout, you’d feel tired, shaky, and nauseated.

A 2001 study conducted by the University of Pavia in Italy showed that most prayers, such as the rosary, are similar to Hindu and Taoist traditions of 5.5 breaths per minute.

Once a day, they were to lie down, take a brief inhale, and then exhale to a count of 6. As they progressed, they could inhale to a count of 4 and exhale to 8, with the goal of reaching a half-minute exhale after six months of practice.

The right nostril is a gas pedal. When you’re inhaling primarily through this channel, circulation speeds up, your body gets hotter, and cortisol levels, blood pressure, and heart rate all increase. This happens because breathing through the right side of the nose activates the sympathetic nervous system, the “fight or flight” mechanism that puts the body in a more elevated state of alertness and readiness. Breathing through the right nostril will also feed more blood to the opposite hemisphere of the brain, specifically to the prefrontal cortex, which has been associated with logical decisions, language, and computing. Inhaling through the left nostril has the opposite effect: it works as a kind of brake system to the right nostril’s accelerator. The left nostril is more deeply connected to the parasympathetic nervous system, the rest-and-relax side that lowers blood pressure, cools the body, and reduces anxiety. Left-nostril breathing shifts blood flow to the opposite side of the prefrontal cortex, to the area that influences creative thought and plays a role in the formation of mental abstractions and the production of negative emotions. In 2015, researchers at the University of California, San Diego, recorded the breathing patterns of a schizophrenic woman over the course of three consecutive years and found that she had a “significantly greater” left-nostril dominance. This breathing habit, they hypothesized, was likely overstimulating the right-side “creative part” of her brain, and as a result prodding her imagination to run amok. Over several sessions, the researchers taught her to breathe through her opposite, “logical” nostril, and she experienced far fewer hallucinations.

At the end of 30 breaths, exhale to the natural conclusion, leaving about a quarter of the air left in the lungs, then hold that breath for as long as possible. Once you’ve reached your breathhold limit, take one huge inhale and hold it another 15 seconds. Very gently, move that fresh breath of air around the chest and to the shoulders, then exhale and start the heavy breathing again. Repeat the whole pattern three or four rounds and add in some cold exposure (cold shower, ice bath, naked snow angels) a few times a week. This flip-flopping—breathing all-out, then not at all, getting really cold and then hot again—is the key to Tummo’s magic. It forces the body into high stress one minute, a state of extreme relaxation the next. Carbon dioxide levels in the blood crash, then they build back up. Tissues become oxygen deficient and then flooded again. The body becomes more adaptable and flexible and learns that all these physiological responses can come under our control. Conscious heavy breathing, McGee told me, allows us to bend so that we don’t get broken. •

In a single breath, more molecules of air will pass through your nose than all the grains of sand on all the world’s beaches—trillions and trillions of them.

People with anorexia or panic or obsessive-compulsive disorders consistently have low carbon dioxide levels and a much greater fear of holding their breath. To avoid another attack, they breathe far too much and eventually become hypersensitized to carbon dioxide and panic if they sense a rise in this gas. They are anxious because they’re overbreathing, overbreathing because they’re anxious.

The key is to find a rhythm that works for you,” Olsson keeps saying. The rhythm is definitely not working. I return to my more manageable practice, inhaling for two steps and exhaling for five, a pattern competitive cyclists use.

The Grofs’ technique was essentially Tummo cranked up to 11. It involved lying on a floor in a dark room, with loud music playing, breathing as hard and quickly as you could for up to three hours. Willingly breathing to the point of exhaustion, they found, could place patients in a state of stress where they could access subconscious and unconscious thoughts. Essentially, the therapy helped people blow a fuse in their minds so they could return to a state of groovy calm.

There were also athletes like Olympians Ramon Andersson, Matthew Dunn, and Sanya Richards-Ross, who had used breathing less methods. All of them claimed to have gained a boost in performance and blunted the symptoms of respiratory problems, simply by decreasing the volume of air in their lungs and increasing the carbon dioxide in their bodies.
