CHAPTER 16
LEARNING TO INHABIT YOUR BODY:
YOGA
As we begin to re-experience a visceral reconnection with the
needs of our bodies, there is a brand new capacity to warmly love
the self. We experience a new quality of authenticity in our caring,
which redirects our attention to our health, our diets, our energy,
our time management. This enhanced care for the self arises
spontaneously and naturally, not as a response to a “should.” We
are able to experience an immediate and intrinsic pleasure in self-
care.
—Stephen Cope, Yoga and the Quest for the True Self
he first time I saw Annie she was slumped over in a chair in my
waiting room, wearing faded jeans and a purple Jimmy Cliff T‑shirt.
Her legs were visibly shaking, and she kept staring at the floor even after I
invited her in. I had very little information about her, other than that she
was forty-seven years old and taught special-needs children. Her body
communicated clearly that she was too terrified to engage in conversation—
or even to provide routine information about her address or insurance plan.
People who are this scared can’t think straight, and any demand to perform
will only make them shut down further. If you insist, they’ll run away and
you’ll never see them again.
Annie shuffled into my office and remained standing, barely breathing,
looking like a frozen bird. I knew we couldn’t do anything until I could help
her quiet down. Moving to within six feet of her and making sure she had
unobstructed access to the door, I encouraged her to take slightly deeper
breaths. I breathed with her and asked her to follow my example, gently
raising my arms from my sides as she inhaled and lowering them as I
exhaled, a qigong technique that one of my Chinese students had taught me.
She stealthily followed my movements, her eyes still fixed on the floor. We
spent about half an hour this way. From time to time I quietly asked her to
notice how her feet felt against the floor and how her chest expanded and
contracted with each breath. Her breath gradually became slower and
deeper, her face softened, her spine straightened a bit, and her eyes lifted to
about the level of my Adam’s apple. I began to sense the person behind that
overwhelming terror. Finally she looked more relaxed and showed me the
glimmer of a smile, a recognition that we both were in the room. I
suggested that we stop there for now—I’d made enough demands on her—
and asked whether she would like to come back a week later. She nodded
and muttered, “You sure are weird.”
As I got to know Annie, I inferred from the notes she wrote and the
drawings she gave me that she had been dreadfully abused by both her
father and her mother as a very young child. The full story was only
gradually revealed, as she slowly learned to call up some of the things that
had happened to her without her body being hijacked into uncontrollable
anxiety.
I learned that Annie was extraordinarily skilled and caring in her work
with special-needs kids. (I tried out quite a few of the techniques she told
me about with the children in our own clinic and found them extremely
helpful). She would talk freely about the children she taught but would clam
up immediately if we verged on her relationships with adults. I knew she
was married, but she barely mentioned her husband. She often coped with
disagreements and confrontations by making her mind disappear. When she
felt overwhelmed she’d cut her arms and breasts with a razor blade. She had
spent years in various forms of therapy and had tried many different
medications, which had done little to help her deal with the imprints of her
horrendous past. She had also been admitted to several psychiatric hospitals
to manage her self-destructive behaviors, again without much apparent
benefit.
In our early therapy sessions, because Annie could only hint at what
she was feeling and thinking before she would shut down and freeze, we
focused on calming the physiological chaos within. We used every
technique that I had learned over the years, like breathing with a focus on
the out breath, which activates the relaxing parasympathetic nervous
system. I also taught her to use her fingers to tap a sequence of acupressure
points on various parts of her body, a practice often taught under the name
EFT (Emotional Freedom Technique), which has been shown to help
patients stay within the window of tolerance and often has positive effects
on PTSD symptoms.1
THE LEGACY OF INESCAPABLE SHOCK
Because we can now identify the brain circuits involved in the alarm
system, we know, more or less, what was happening in Annie’s brain as she
sat that first day in my waiting room: Her smoke detector, her amygdala,
had been rewired to interpret certain situations as harbingers of life-
threatening danger, and it was sending urgent signals to her survival brain to
fight, freeze, or flee. Annie had all these reactions simultaneously—she was
visibly agitated and mentally shut down.
As we’ve seen, broken alarm systems can manifest in various ways,
and if your smoke detector malfunctions, you cannot trust the accuracy of
your perceptions. For example, when Annie started to like me she began to
look forward to our meetings, but she would arrive at my office in an
intense panic. One day she had a flashback of feeling excited that her father
was coming home soon—but later that evening he molested her. For the
first time, she realized that her mind automatically associated excitement
about seeing someone she loved with the terror of being molested.
Small children are particularly adept at compartmentalizing experience,
so that Annie’s natural love for her father and her dread of his assaults were
held in separate states of consciousness. As an adult Annie blamed herself
for her abuse, because she believed that the loving, excited little girl she
once was had led her father on—that she had brought the molestation upon
herself. Her rational mind told her this was nonsense, but this belief
emanated from deep within her emotional, survival brain, from the basic
wiring of her limbic system. It would not change until she felt safe enough
within her body to mindfully go back into that experience and truly know
how that little girl had felt and acted during the abuse.
THE NUMBING WITHIN
One of the ways the memory of helplessness is stored is as muscle tension
or feelings of disintegration in the affected body areas: head, back, and
limbs in accident victims, vagina and rectum in victims of sexual abuse.
The lives of many trauma survivors come to revolve around bracing against
and neutralizing unwanted sensory experiences, and most people I see in
my practice have become experts in such self-numbing. They may become
serially obese or anorexic or addicted to exercise or work. At least half of
all traumatized people try to dull their intolerable inner world with drugs or
alcohol. The flip side of numbing is sensation seeking. Many people cut
themselves to make the numbing go away, while others try bungee jumping
or high-risk activities like prostitution and gambling. Any of these methods
can give them a false and paradoxical feeling of control.
When people are chronically angry or scared, constant muscle tension
ultimately leads to spasms, back pain, migraine headaches, fibromyalgia,
and other forms of chronic pain. They may visit multiple specialists,
undergo extensive diagnostic tests, and be prescribed multiple medications,
some of which may provide temporary relief but all of which fail to address
the underlying issues. Their diagnosis will come to define their reality
without ever being identified as a symptom of their attempt to cope with
trauma.
The first two years of my therapy with Annie focused on helping her
learn to tolerate her physical sensations for what they were—just sensations
in the present, with a beginning, a middle, and an end. We worked on
helping her stay calm enough to notice what she felt without judgment, so
she could observe these unbidden images and feelings as residues of a
terrible past and not as unending threats to her life today.
Patients like Annie continuously challenge us to find new ways of
helping people regulate their arousal and control their own physiology. That
is how my Trauma Center colleagues and I stumbled upon yoga.
FINDING OUR WAY TO YOGA: BOTTOM-UP
REGULATION
Our involvement with yoga started in 1998 when Jim Hopper and I first
heard about a new biological marker, heart rate variability (HRV), that had
recently been discovered to be a good measure of how well the autonomic
nervous system is working. As you’ll recall from chapter 5, the autonomic
nervous system is our brain’s most elementary survival system, its two
branches regulating arousal throughout the body. Roughly speaking, the
sympathetic nervous system (SNS) uses chemicals like adrenaline to fuel
the body and brain to take action, while the parasympathetic nervous
system (PNS) uses acetylcholine to help regulate basic body functions like
digestion, wound healing, and sleep and dream cycles. When we’re at our
best, these two systems work closely together to keep us in an optimal state
of engagement with our environment and with ourselves.
Heart rate variability measures the relative balance between the
sympathetic and the parasympathetic systems. When we inhale, we
stimulate the SNS, which results in an increase in heart rate. Exhalations
stimulate the PNS, which decreases how fast the heart beats. In healthy
individuals inhalations and exhalations produce steady, rhythmical
fluctuations in heart rate: Good heart rate variability is a measure of basic
well-being.
Why is HRV important? When our autonomic nervous system is well
balanced, we have a reasonable degree of control over our response to
minor frustrations and disappointments, enabling us to calmly assess what
is going on when we feel insulted or left out. Effective arousal modulation
gives us control over our impulses and emotions: As long as we manage to
stay calm, we can choose how we want to respond. Individuals with poorly
modulated autonomic nervous systems are easily thrown off balance, both
mentally and physically. Since the autonomic nervous system organizes
arousal in both body and brain, poor HRV—that is, a lack of fluctuation in
heart rate in response to breathing—not only has negative effects on
thinking and feeling but also on how the body responds to stress. Lack of
coherence between breathing and heart rate makes people vulnerable to a
variety of physical illnesses, such as heart disease and cancer, in addition to
mental problems such as depression and PTSD.2
In order to study this issue further, we acquired a machine to measure
HRV and started to put bands around the chests of research subjects with
and without PTSD to record the depth and rhythm of their breathing while
little monitors attached to their earlobes picked up their pulse. After we’d
tested about sixty subjects, it became clear that people with PTSD have
unusually low HRV. In other words, in PTSD the sympathetic and
parasympathetic nervous systems are out of sync.3 This added a new twist
to the complicated trauma story: We confirmed that yet another brain
regulatory system was not functioning as it should.4 Failure to keep this
system in balance is one explanation why traumatized people like Annie are
so vulnerable to overrespond to relatively minor stresses: The biological
systems that are meant to help us cope with the vagaries of life fail to meet
the challenge.
Our next scientific question was: Is there a way for people to improve
their HRV? I had a personal incentive to explore this question, as I had
discovered that my own HRV was not nearly robust enough to guarantee
long-term physical health. An Internet search turned up studies showing
that marathon running markedly increased HRV. Sadly, that was of little
use, since neither I nor our patients were good candidates for the Boston
Marathon. Google also listed seventeen thousand yoga sites claiming that
that yoga improved HRV, but we were unable to find any supporting
studies. Yogis may have developed a wonderful method to help people find
internal balance and health, but back in 1998 not much work had been done
on evaluating their claims with the tools of the Western medical tradition.
Heart rate variability (HRV) in a well-regulated person. The rising and falling black lines
represent breathing, in this case slow and regular inhalations and exhalations. The gray area
shows fluctuations in heart rate. Whenever this individual inhales, his heart rate goes up;
during exhalations the heart slows down. This pattern of heart rate variability reflects excellent
physiological health.
Responding to upset. When someone remembers an upsetting experience, breathing speeds up
and becomes irregular, as does heart rate. Heart and breath no longer stay perfectly in sync.
This is a normal response.
HRV in PTSD. Breathing is rapid and shallow. Heart rate is slow and out of synch with the
breath. This is a typical pattern of a shut-down person with chronic PTSD.
A person with chronic PTSD reliving a trauma memory. Breathing initially is labored and
deep, typical of a panic reaction. The heart races out of synch with the breath. This is followed
by rapid, shallow breathing and slow heart rate, signs that the person is shutting down.
Since then, however, scientific methods have confirmed that changing
the way one breathes can improve problems with anger, depression, and
anxiety5 and that yoga can positively affect such wide-ranging medical
problems as high blood pressure, elevated stress hormone secretion,6
asthma, and low-back pain.7 However, no psychiatric journal had published
a scientific study of yoga for PTSD until our own work appeared in 2014.8
As it happened, a few days after our Internet search a lanky yoga
teacher named David Emerson walked through the front door of the Trauma
Center. He told us that he’d developed a modified form of hatha yoga to
deal with PTSD and that he’d been holding classes for veterans at a local
vet center and for women in the Boston Area Rape Crisis Center. Would we
be interested in working with him? Dave’s visit eventually grew into a very
active yoga program, and in due course we received the first grant from the
National Institutes of Health to study the effects of yoga on PTSD. Dave’s
work also contributed to my developing my own regular yoga practice and
becoming a frequent teacher at Kripalu, a yoga center in the Berkshire
Mountains in western Massachusetts. (Along the way, my own HRV pattern
improved as well.)
In choosing to explore yoga to improve HRV we were taking an
expansive approach to the problem. We could simply have used any of a
number of reasonably priced handheld devices that train people to slow
their breathing and synchronize it with their heart rate, resulting in a state of
“cardiac coherence” like the pattern shown in the first illustration above.9
Today there are a variety of apps that can help improve HRV with the aid of
a smartphone.10 In our clinic we have workstations where patients can train
their HRV, and I urge all my patients who, for one reason or another, cannot
practice yoga, martial arts, or qigong to train themselves at home. (See
Resources for more information.)
EXPLORING YOGA
Our decision to study yoga led us deeper into trauma’s impact on the body.
Our first experimental yoga classes met in a room generously donated by a
nearby studio. David Emerson and his colleagues Dana Moore and Jodi
Carey volunteered as instructors, and my research team figured out how we
could best measure yoga’s effects on psychological functioning. We put
flyers in neighborhood supermarkets and laundromats to advertise our
classes and interviewed dozens of people who called in response.
Ultimately we selected thirty-seven women who had severe trauma histories
and who had already received many years of therapy without much benefit.
Half the volunteers were selected at random for the yoga group, while the
others would receive a well-established mental health treatment, dialectical
behavior therapy (DBT), which teaches people how to apply mindfulness to
stay calm and in control. Finally, we commissioned an engineer at MIT to
build us a complicated computer that could measure HRV simultaneously in
eight different people. (In each study group there were multiple classes,
each with no more than eight participants.) While yoga significantly
improved arousal problems in PTSD and dramatically improved our
subjects’ relationships to their bodies (“I now take care of my body”; “I
listen to what my body needs”), eight weeks of DBT did not affect their
arousal levels or PTSD symptoms. Thus, our interest in yoga gradually
evolved from a focus on learning whether yoga can change HRV (which it
can)11 to helping traumatized people learn to comfortably inhabit their
tortured bodies.
Over time we also started a yoga program for marines at Camp Lejeune
and have worked successfully with various other programs to implement
yoga programs for veterans with PTSD. Even though we have no formal
research data on the veterans, it looks as if yoga is at least as effective for
them as it has been for the women in our studies.
All yoga programs consist of a combination of breath practices
(pranayama), stretches or postures (asanas), and meditation. Different
schools of yoga emphasize variations in intensity and focus within these
core components. For example, variations in the speed and depth of
breathing and use of the mouth, nostrils, and throat all produce different
results, and some techniques have powerful effects on energy.12 In our
classes we keep the approach simple. Many of our patients are barely aware
of their breath, so learning to focus on the in and out breath, to notice
whether the breath was fast or slow, and to count breaths in some poses can
be a significant accomplishment.13
We gradually introduce a limited number of classic postures. The
emphasis is not on getting the poses “right” but on helping the participants
notice which muscles are active at different times. The sequences are
designed to create a rhythm between tension and relaxation—something we
hope they will begin to perceive in their day-to-day lives.
We do not teach meditation as such, but we do foster mindfulness by
encouraging students to observe what is happening in different parts of the
body from pose to pose. In our studies we keep seeing how difficult it is for
traumatized people to feel completely relaxed and physically safe in their
bodies. We measure our subjects’ HRV by placing tiny monitors on their
arms during shavasana, the pose at the end of most classes during which
practitioners lie face up, palms up, arms and legs relaxed. Instead of
relaxation we picked up too much muscle activity to get a clear signal.
Rather than going into a state of quiet repose, our students’ muscles often
continue to prepare them to fight unseen enemies. A major challenge in
recovering from trauma remains being able to achieve a state of total
relaxation and safe surrender.
LEARNING SELF-REGULATION
After seeing the success of our pilot studies, we established a therapeutic
yoga program at the Trauma Center. I thought that this might be an
opportunity for Annie to develop a more caring relationship with her body,
and I urged her to try it. The first class was difficult. Merely being given an
adjustment by the instructor was so terrifying that she went home and
slashed herself—her malfunctioning alarm system interpreted even a gentle
touch on her back as an assault. At the same time Annie realized that yoga
might offer her a way to liberate herself from the constant sense of danger
that she felt in her body. With my encouragement she returned the following
week.
Annie had always found it easier to write about her experiences than to
talk about them. After her second yoga class she wrote to me: “I don’t know
all of the reasons that yoga terrifies me so much, but I do know that it will
be an incredible source of healing for me and that is why I am working on
myself to try it. Yoga is about looking inward instead of outward and
listening to my body, and a lot of my survival has been geared around never
doing those things. Going to the class today my heart was racing and part of
me really wanted to turn around, but then I just kept putting one foot in
front of the other until I got to the door and went in. After the class I came
home and slept for four hours. This week I tried doing yoga at home and the
words came to me ‘Your body has things to say.’ I said back to myself, ‘I
will try and listen.’”
A few days later Annie wrote: “Some thoughts during and after yoga
today. It occurred to me how disconnected I must be from my body when I
cut it. When I was doing the poses I noticed that my jaw and the whole area
from where my legs end to my bellybutton is where I am tight, tense and
holding the pain and memories. Sometimes you have asked me where I feel
things and I can’t even begin to locate them, but today I felt those places
very clearly and it made me want to cry in a gentle kind of way.”
The following month both of us went on vacation and, invited to stay in
touch, Annie wrote to me again: “I’ve been doing yoga on my own in a
room that overlooks the lake. I’m continuing to read the book you lent me
[Stephen Cope’s wonderful Yoga and the Quest for the True Self]. It’s really
interesting to think about how much I have been refusing to listen to my
body, which is such an important part of who I am. Yesterday when I did
yoga I thought about letting my body tell me the story it wants to tell and in
the hip opening poses there was a lot of pain and sadness. I don’t think my
mind is going to let really vivid images come up as long as I am away from
home, which is good. I think now about how unbalanced I have been and
about how hard I have tried to deny the past, which is a part of my true self.
There is so much I can learn if I am open to it and then I won’t have to fight
myself every minute of every day.”
One of the hardest yoga positions for Annie to tolerate was one that’s
often called Happy Baby, in which you lie on your back with your knees
deeply bent and the soles of your feet pointing to the ceiling, while holding
your toes with your hands. This rotates the pelvis into a wide-open position.
It’s easy to understand why this would make a rape victim feel extremely
vulnerable. Yet, as long as Happy Baby (or any posture that resembles it)
precipitates intense panic, it is difficult to be intimate. Learning how to
comfortably assume Happy Baby is a challenge for many patients in our
yoga classes.
GETTING TO KNOW ME: CULTIVATING
INTEROCEPTION
One of the clearest lessons from contemporary neuroscience is that our
sense of ourselves is anchored in a vital connection with our bodies.14 We
do not truly know ourselves unless we can feel and interpret our physical
sensations; we need to register and act on these sensations to navigate
safely through life.15 While numbing (or compensatory sensation seeking)
may make life tolerable, the price you pay is that you lose awareness of
what is going on inside your body and, with that, the sense of being fully,
sensually alive.
In chapter 6 I discussed alexithymia, the technical term for not being
able to identify what is going on inside oneself.16 People who suffer from
alexithymia tend to feel physically uncomfortable but cannot describe
exactly what the problem is. As a result they often have multiple vague and
distressing physical complaints that doctors can’t diagnose. In addition,
they can’t figure out for themselves what they’re really feeling about any
given situation or what makes them feel better or worse. This is the result of
numbing, which keeps them from anticipating and responding to the
ordinary demands of their bodies in quiet, mindful ways. At the same time,
it muffles the everyday sensory delights of experiences like music, touch,
and light, which imbue life with value. Yoga turned out to be a terrific way
to (re)gain a relationship with the interior world and with it a caring, loving,
sensual relationship to the self.
If you are not aware of what your body needs, you can’t take care of it.
If you don’t feel hunger, you can’t nourish yourself. If you mistake anxiety
for hunger, you may eat too much. And if you can’t feel when you’re
satiated, you’ll keep eating. This is why cultivating sensory awareness is
such a critical aspect of trauma recovery. Most traditional therapies
downplay or ignore the moment-to-moment shifts in our inner sensory
world. But these shifts carry the essence of the organism’s responses: the
emotional states that are imprinted in the body’s chemical profile, in the
viscera, in the contraction of the striated muscles of the face, throat, trunk,
and limbs.17 Traumatized people need to learn that they can tolerate their
sensations, befriend their inner experiences, and cultivate new action
patterns.
In yoga you focus your attention on your breathing and on your
sensations moment to moment. You begin to notice the connection between
your emotions and your body—perhaps how anxiety about doing a pose
actually throws you off balance. You begin to experiment with changing the
way you feel. Will taking a deep breath relieve that tension in your
shoulder? Will focusing on your exhalations produce a sense of calm?18
Simply noticing what you feel fosters emotional regulation, and it helps
you to stop trying to ignore what is going on inside you. As I often tell my
students, the two most important phrases in therapy, as in yoga, are “Notice
that” and “What happens next?” Once you start approaching your body with
curiosity rather than with fear, everything shifts.
Body awareness also changes your sense of time. Trauma makes you
feel as if you are stuck forever in a helpless state of horror. In yoga you
learn that sensations rise to a peak and then fall. For example, if an
instructor invites you to enter a particularly challenging position, you may
at first feel a sense of defeat or resistance, anticipating that you won’t be
able to tolerate the feelings brought up by this particular position. A good
yoga teacher will encourage you to just notice any tension while timing
what you feel with the flow of your breath: “We’ll be holding this position
for ten breaths.” This helps you anticipate the end of discomfort and
strengthens your capacity to deal with physical and emotional distress.
Awareness that all experience is transitory changes your perspective on
yourself.
This is not to say that regaining interoception isn’t potentially
upsetting. What happens when a newly accessed feeling in your chest is
experienced as rage, or fear, or anxiety? In our first yoga study we had a 50
percent dropout rate, the highest of any study we’d ever done. When we
interviewed the patients who’d left, we learned that they had found the
program too intense: Any posture that involved the pelvis could precipitate
intense panic or even flashbacks to sexual assaults. Intense physical
sensations unleashed the demons from the past that had been so carefully
kept in check by numbing and inattention. This taught us to go slow, often
at a snail’s pace. That approach paid off: In our most recent study only one
out of thirty-four participants did not finish.
Effects of a weekly yoga class. After twenty weeks, chronically traumatized women
developed increased activation of critical brain structures involved in self-regulation: the insula
and the medial prefrontal cortex.
YOGA AND THE NEUROSCIENCE OF SELF-AWARENESS
During the past few years brain researchers such as my colleagues Sara
Lazar and Britta Hölzel at Harvard have shown that intensive meditation
has a positive effect on exactly those brain areas that are critical for
physiological self-regulation.19 In our latest yoga study, with six women
with histories of profound early trauma, we also found the first indications
that twenty weeks of yoga practice increased activation of the basic self-
system, the insula and the medial prefrontal cortex (see chapter 6). This
research needs much more work, but it opens up new perspectives on how
actions that involve noticing and befriending the sensations in our bodies
can produce profound changes in both mind and brain that can lead to
healing from trauma.
After each of our yoga studies, we asked the participants what effect
the classes had had on them. We never mentioned the insula or
interoception; in fact, we kept the discussion and explanation to a minimum
so that they could focus inward.
Here is a sample of their responses:
“My emotions feel more powerful. Maybe it’s just that I can
recognize them now.”
“I can express my feelings more because I can recognize them
more. I feel them in my body, recognize them, and address
them.”
“I now see choices, multiple paths. I can decide and I can
choose my life, it doesn’t have to be repeated or be experienced
like a child.”
“I was able to move my body and be in my body in a safe place
and without hurting myself/getting hurt.”
LEARNING TO COMMUNICATE
People who feel safe in their bodies can begin to translate the memories that
previously overwhelmed them into language. After Annie had been
practicing yoga three times a week for about a year, she noticed that she
was able to talk much more freely to me about what had happened to her.
She thought this almost miraculous. One day, when she knocked over a
glass of water, I got up from my chair and approached her with a Kleenex
box, saying, “Let me clean that up.” This precipitated a brief, intense panic
reaction. She was quickly able to contain herself, though, and explained
why those particular words were so upsetting to her—they were what her
father would say after he’d raped her. Annie wrote to me after that session:
“Did you notice that I have been able to say the words out loud? I didn’t
have to write them down to tell you what was happening. I didn’t lose trust
in you because you said words that triggered me. I understood that the
words were a trigger and not terrible words that no one should say.”
Annie continues to practice yoga and to write to me about her
experiences: “Today I went to a morning yoga class at my new yoga studio.
