How Yoga Tin can Wreck Your Body
Editors' notation : We're resurfacing this 2012 magazine article for Smarter Living and then you can feel a little less guilty nearly skipping that yoga form.
On a cold Saturday in early 2009, Glenn Black, a yoga teacher of nearly 4 decades, whose devoted clientele includes a number of celebrities and prominent gurus, was giving a master class at Sankalpah Yoga in Manhattan. Black is, in many ways, a archetype yogi: he studied in Pune, India, at the plant founded by the legendary B. K. South. Iyengar, and spent years in solitude and meditation. He now lives in Rhinebeck, N.Y., and often teaches at the nearby Omega Found, a New Age emporium spread over most 200 acres of woods and gardens. He is known for his rigor and his down-to-earth style. But this was not why I sought him out: Black, I'd been told, was the person to speak with if you wanted to know not about the virtues of yoga but rather about the harm information technology could do. Many of his regular clients came to him for bodywork or rehabilitation following yoga injuries. This was the state of affairs I found myself in. In my 30s, I had somehow managed to rupture a disk in my lower dorsum and found I could forestall bouts of hurting with a selection of yoga postures and abdominal exercises. Then, in 2007, while doing the extended-side-angle pose, a posture hailed as a cure for many diseases, my back gave mode. With it went my belief, naïve in retrospect, that yoga was a source only of healing and never harm.
At Sankalpah Yoga, the room was packed; roughly half the students were said to be teachers themselves. Black walked around the room, joking and talking. "Is this yoga?" he asked every bit we sweated through a pose that seemed to demand superhuman endurance. "It is if you're paying attention." His approach was almost free-form: he made us agree poses for a long time but taught no inversions and few classical postures. Throughout the class, he urged us to pay attention to the thresholds of pain. "I brand it every bit hard as possible," he told the grouping. "It'due south upward to you lot to arrive easy on yourself." He drove his point home with a cautionary tale. In Bharat, he recalled, a yogi came to study at Iyengar's school and threw himself into a spinal twist. Blackness said he watched in disbelief as three of the human being'southward ribs gave way — pop, popular, popular.
After course, I asked Blackness about his approach to teaching yoga — the emphasis on holding only a few elementary poses, the absence of mutual inversions like headstands and shoulder stands. He gave me the kind of respond you'd expect from whatever yoga teacher: that awareness is more important than rushing through a serial of postures just to say you'd done them. But then he said something more than radical. Blackness has come to believe that "the vast majority of people" should surrender yoga altogether. It's simply also likely to cause impairment.
Non but students but celebrated teachers besides, Black said, hurt themselves in droves because most have underlying physical weaknesses or issues that make serious injury all but inevitable. Instead of doing yoga, "they need to be doing a specific range of motions for articulation, for organ condition," he said, to strengthen weak parts of the body. "Yoga is for people in skilful physical condition. Or information technology tin can be used therapeutically. It's controversial to say, but it really shouldn't be used for a general class."
Black seemingly reconciles the dangers of yoga with his own teaching of it by working hard at knowing when a student "shouldn't do something — the shoulder stand, the headstand or putting any weight on the cervical vertebrae." Though he studied with Shmuel Tatz, a legendary Manhattan-based concrete therapist who devised a method of massage and alignment for actors and dancers, he acknowledges that he has no formal training for determining which poses are good for a student and which may exist problematic. What he does have, he says, is "a ton of experience."
"To come to New York and practice a class with people who have many bug and say, 'O.M., we're going to practise this sequence of poses today' — it but doesn't work."

According to Black, a number of factors take converged to heighten the risk of practicing yoga. The biggest is the demographic shift in those who study it. Indian practitioners of yoga typically squatted and sat cross-legged in daily life, and yoga poses, or asanas, were an outgrowth of these postures. Now urbanites who sit in chairs all twenty-four hour period walk into a studio a couple of times a calendar week and strain to twist themselves into ever-more than-hard postures despite their lack of flexibility and other concrete problems. Many come to yoga as a gentle alternative to vigorous sports or for rehabilitation for injuries. But yoga's exploding popularity — the number of Americans doing yoga has risen from near 4 million in 2001 to what some judge to be as many as 20 million in 2011 — means that at that place is now an abundance of studios where many teachers lack the deeper training necessary to recognize when students are headed toward injury. "Today many schools of yoga are just almost pushing people," Blackness said. "You can't believe what's going on — teachers jumping on people, pushing and pulling and proverb, 'You should be able to exercise this past now.' It has to practice with their egos."
When yoga teachers come up to him for bodywork after suffering major traumas, Black tells them, "Don't practise yoga."
"They await at me like I'm crazy," he goes on to say. "And I know if they continue, they won't be able to take information technology." I asked him about the worst injuries he'd seen. He spoke of well-known yoga teachers doing such basic poses equally downwardly-facing canis familiaris, in which the body forms an inverted 5, so strenuously that they tore Achilles tendons. "It'south ego," he said. "The whole signal of yoga is to get rid of ego." He said he had seen some "pretty gruesome hips." "One of the biggest teachers in America had nil motion in her hip joints," Black told me. "The sockets had become and then degenerated that she had to have hip replacements." I asked if she yet taught. "Oh, yeah," Black replied. "In that location are other yoga teachers that have such bad backs they accept to lie downwards to teach. I'd be so embarrassed."
Among devotees, from gurus to acolytes forever carrying their rolled-up mats, yoga is described as a virtually miraculous agent of renewal and healing. They celebrate its abilities to calm, cure, energize and strengthen. And much of this appears to be true: yoga can lower your blood pressure, brand chemicals that act as antidepressants, even better your sexual practice life. Only the yoga community long remained silent about its potential to inflict blinding hurting. Jagannath G. Gune, who helped revive yoga for the modern era, made no allusion to injuries in his journal Yoga Mimansa or his 1931 volume "Asanas." Indra Devi avoided the outcome in her 1953 best seller "Forever Immature, Forever Good for you," as did B. Chiliad. S. Iyengar in his seminal "Lite on Yoga," published in 1965. Reassurances near yoga'southward safety also make regular appearances in the how-to books of such yogis as Swami Sivananda, K. Pattabhi Jois and Bikram Choudhury. "Real yoga is as safe as mother'due south milk," declared Swami Gitananda, a guru who made 10 earth tours and founded ashrams on several continents.
But a growing body of medical testify supports Black's contention that, for many people, a number of commonly taught yoga poses are inherently risky. The first reports of yoga injuries appeared decades ago, published in some of the world'due south nearly respected journals — among them, Neurology, The British Medical Periodical and The Periodical of the American Medical Association. The problems ranged from relatively mild injuries to permanent disabilities. In one case, a male college student, after more than than a twelvemonth of doing yoga, decided to intensify his exercise. He would sit down upright on his heels in a kneeling position known equally vajrasana for hours a 24-hour interval, chanting for globe peace. Presently he was experiencing difficulty walking, running and climbing stairs.
Doctors traced the trouble to an unresponsive nervus, a peripheral branch of the sciatic, which runs from the lower spine through the buttocks and down the legs. Sitting in vajrasana deprived the branch that runs beneath the knee of oxygen, tiresome the nervus. One time the student gave up the pose, he improved rapidly. Clinicians recorded a number of like cases and the condition fifty-fifty got its own proper name: "yoga human foot drib."
More troubling reports followed. In 1972 a prominent Oxford neurophysiologist, West. Ritchie Russell, published an article in The British Medical Journal arguing that, while rare, some yoga postures threatened to cause strokes even in relatively young, healthy people. Russell found that brain injuries arose non but from direct trauma to the head only likewise from quick movements or excessive extensions of the neck, such as occur in whiplash — or certain yoga poses. Commonly, the cervix can stretch backward 75 degrees, forward 40 degrees and sideways 45 degrees, and it can rotate on its axis nearly 50 degrees. Yoga practitioners typically motion the vertebrae much farther. An intermediate student can easily plow his or her neck 90 degrees — nearly twice the normal rotation.
Hyperflexion of the neck was encouraged by experienced practitioners. Iyengar emphasized that in cobra pose, the caput should arch "every bit far dorsum equally possible" and insisted that in the shoulder stand, in which the chin is tucked deep in the chest, the trunk and caput forming a right bending, "the body should exist in ane direct line, perpendicular to the flooring." He called the pose, said to stimulate the thyroid, "one of the greatest boons conferred on humanity by our ancient sages."

Farthermost motions of the caput and neck, Russell warned, could wound the vertebral arteries, producing clots, swelling and constriction, and somewhen wreak havoc in the brain. The basilar artery, which arises from the union of the two vertebral arteries and forms a wide conduit at the base of the encephalon, was of particular business concern. It feeds such structures as the pons (which plays a role in respiration), the cerebellum (which coordinates the muscles), the occipital lobe of the outer brain (which turns center impulses into images) and the thalamus (which relays sensory messages to the outer brain). Reductions in claret flow to the basilar artery are known to produce a diversity of strokes. These rarely affect language and conscious thinking (often said to exist located in the frontal cortex) simply can severely damage the trunk'southward core mechanism and sometimes exist fatal. The majority of patients suffering such a stroke do recover most functions. Merely in some cases headaches, imbalance, dizziness and difficulty in making fine movements persist for years.
Russell as well worried that when strokes hitting yoga practitioners, doctors might fail to trace their cause. The cognitive harm, he wrote, "may exist delayed, perhaps to announced during the night post-obit, and this delay of some hours distracts attention from the earlier precipitating cistron."
In 1973, a year after Russell's newspaper was published, Willibald Nagler, a renowned authority on spinal rehabilitation at Cornell University Medical College, published a newspaper on a strange example. A healthy woman of 28 suffered a stroke while doing a yoga position known as the wheel or up bow, in which the practitioner lies on her back, then lifts her torso into a semicircular arc, balancing on hands and anxiety. An intermediate stage ofttimes involves raising the torso and resting the crown of the caput on the floor. While balanced on her caput, her neck bent far astern, the woman "suddenly felt a severe throbbing headache." She had difficulty getting up, and when helped into a standing position, was unable to walk without assist. The adult female was rushed to the infirmary. She had no awareness on the right side of her body; her left arm and leg responded poorly to her commands. Her eyes kept glancing involuntarily to the left. And the left side of her face up showed a contracted educatee, a drooping upper eyelid and a rising lower lid — a cluster of symptoms known every bit Horner'south syndrome. Nagler reported that the woman also had a tendency to autumn to the left.
Her doctors plant that the adult female's left vertebral avenue, which runs between the first 2 cervical vertebrae, had narrowed considerably and that the arteries feeding her cerebellum had undergone astringent displacement. Given the lack of advanced imaging technologies at the fourth dimension, an exploratory operation was conducted to go a clearer sense of her injuries. The surgeons who opened her skull found that the left hemisphere of her cerebellum suffered a major failure of blood supply that resulted in much dead tissue and that the site was seeped in secondary hemorrhages.
The patient began an intensive program of rehabilitation. Two years later, she was able to walk, Nagler reported, "with [a] broad-based gait." But her left arm continued to wander and her left heart continued to prove Horner's syndrome. Nagler concluded that such injuries appeared to be rare but served as a alarm about the hazards of "forceful hyperextension of the cervix." He urged caution in recommending such postures, particularly to individuals of middle age.
The experience of Nagler's patient was not an isolated incident. A few years later, a 25-year-old man was rushed to Northwestern Memorial Hospital, in Chicago, lament of blurred vision, difficulty swallowing and controlling the left side of his body. Steven H. Hanus, a medical student at the time, became interested in the case and worked with the chairman of the neurology department to determine the cause (he afterward published the results with several colleagues). The patient had been in first-class health, practicing yoga every morning time for a year and a one-half. His routine included spinal twists in which he rotated his head far to the left and far to the correct. Then he would do a shoulder stand with his neck "maximally flexed against the bare floor," simply equally Iyengar had instructed, remaining in the inversion for about five minutes. A series of bruises ran down the man'southward lower neck, which, the team wrote in The Athenaeum of Neurology, "resulted from repeated contact with the hard flooring surface on which he did yoga exercises." These were a sign of cervix trauma. Diagnostic tests revealed blockages of the left vertebral artery between the c2 and c3 vertebrae; the blood vessel there had suffered "total or most complete occlusion" — in other words, no claret could become through to the brain.
Ii months after his attack, and after much physical therapy, the man was able to walk with a cane. Only, the team reported, he "continued to have pronounced difficulty performing fine movements with his left hand." Hanus and his colleagues ended that the beau's status represented a new kind of danger. Healthy individuals could seriously damage their vertebral arteries, they warned, "by cervix movements that exceed physiological tolerance." Yoga, they stressed, "should be considered as a possible precipitating event." In its written report, the Northwestern team cited not only Nagler's business relationship of his female patient but besides Russell's early warning. Business concern well-nigh yoga'due south safety began to ripple through the medical establishment.
These cases may seem exceedingly rare, but surveys by the Consumer Product Safe Commission showed that the number of emergency-room admissions related to yoga, after years of wearisome increases, was ascent quickly. They went from 13 in 2000 to 20 in 2001. Then they more than doubled to 46 in 2002. These surveys rely on sampling rather than exhaustive reporting — they reveal trends rather than totals — only the spike was nonetheless statistically significant. Only a fraction of the injured visit hospital emergency rooms. Many of those suffering from less serious yoga injuries go to family doctors, chiropractors and diverse kinds of therapists.

Around this time, stories of yoga-induced injuries began to announced in the media. The Times reported that wellness professionals found that the penetrating heat of Bikram yoga, for instance, could raise the risk of overstretching, muscle damage and torn cartilage. One specialist noted that ligaments — the tough bands of cobweb that connect bones or cartilage at a joint — failed to regain their shape once stretched out, raising the gamble of strains, sprains and dislocations.
In 2009, a New York Metropolis team based at Columbia University'due south Higher of Physicians and Surgeons published an aggressive worldwide survey of yoga teachers, therapists and doctors. The answers to the survey'southward fundamental question — What were the about serious yoga-related injuries (disabling and/or of long duration) they had seen? — revealed that the largest number of injuries (231) centered on the lower back. The other main sites were, in declining lodge of prevalence: the shoulder (219), the articulatio genus (174) and the neck (110). Then came stroke. The respondents noted four cases in which yoga'south farthermost bending and contortions resulted in some degree of brain harm. The numbers weren't alarming but the acknowledgment of take chances — nearly four decades after Russell first issued his warning — pointed to a decided shift in the perception of the dangers yoga posed.
In recent years, reformers in the yoga customs take begun to address the issue of yoga-induced damage. In a 2003 article in Yoga Journal, Carol Krucoff — a yoga instructor and therapist who works at the Integrative Medicine center at Duke University in N Carolina — revealed her ain struggles. She told of being filmed one day for national television and after being urged to do more, lifting one foot, grabbing her big toe and stretching her leg into the extended-mitt-to-big-toe pose. As her leg straightened, she felt a sickening popular in her hamstring. The next day, she could barely walk. Krucoff needed concrete therapy and a year of recovery earlier she could fully extend her leg again. The editor of Yoga Journal, Kaitlin Quistgaard, described reinjuring a torn rotator cuff in a yoga course. "I've experienced how yoga can heal," she wrote. "Merely I've as well experienced how yoga tin can hurt — and I've heard the same from plenty of other yogis."
One of the most vocal reformers is Roger Cole, an Iyengar teacher with degrees in psychology from Stanford and the University of California, San Francisco. Cole has written extensively for Yoga Periodical and speaks on yoga safety to the American Higher of Sports Medicine. In one column, Cole discussed the practice of reducing neck angle in a shoulder stand by lifting the shoulders on a stack of folded blankets and letting the caput fall below it. The modification eases the angle between the head and the torso, from 90 degrees to perhaps 110 degrees. Cole ticked off the dangers of doing an unmodified shoulder stand: muscle strains, overstretched ligaments and cervical-disk injuries.
Merely modifications are non always the solution. Timothy McCall, a doctor who is the medical editor of Yoga Journal, called the headstand besides dangerous for general yoga classes. His warning was based partly on his own experience. He found that doing the headstand led to thoracic outlet syndrome, a condition that arises from the pinch of nerves passing from the cervix into the arms, causing tingling in his right hand as well as sporadic numbness. McCall stopped doing the pose, and his symptoms went away. Later, he noted that the inversion could produce other injuries, including degenerative arthritis of the cervical spine and retinal tears (a result of the increased eye force per unit area acquired by the pose). "Unfortunately," McCall concluded, "the negative furnishings of headstand can exist insidious."
Almost a twelvemonth after I first met Glenn Black at his master grade in Manhattan, I received an email from him telling me that he had undergone spinal surgery. "It was a success," he wrote. "Recovery is dull and painful. Telephone call if you like."
The injury, Black said, had its origins in four decades of extreme backbends and twists. He had developed spinal stenosis — a serious condition in which the openings between vertebrae begin to narrow, compressing spinal nerves and causing excruciating pain. Black said that he felt the tenderness commencement 20 years ago when he was coming out of such poses as the plow and the shoulder stand up. 2 years ago, the pain became farthermost. One surgeon said that without treatment, he would eventually exist unable to walk. The surgery took five hours, fusing together several lumbar vertebrae. He would eventually be fine but was under surgeon'due south orders to reduce strain on his lower back. His range of movement would never be the same.
Black is i of the about careful yoga practitioners I know. When I first spoke to him, he said he had never injured himself doing yoga or, as far every bit he knew, been responsible for harming whatever of his students. I asked him if his recent injury could have been built or related to aging. No, he said. It was yoga. "You have to go a different perspective to meet if what y'all're doing is going to eventually be bad for yous."
Black recently took that message to a conference at the Omega Institute, his feelings on the subject area deepened by his recent functioning. But his warnings seemed to fall on deaf ears. "I was a little more than emphatic than usual," he recalled. "My bulletin was that 'Asana is not a panacea or a cure-all. In fact, if y'all do information technology with ego or obsession, yous'll end upwards causing problems.' A lot of people don't similar to hear that."
