Chaos or Calm: Rewiring the Stress Response
By Carrie Demers, MD
Remember the tale "The Lady or the Tiger?" As it ends, the hero is standing before two identical
doors: one conceals a beautiful maiden; the other, a ferocious tiger. The hero must open one of
these doors—the choice is his—but he has no way of knowing which will bring forth the lady and
which will release the tiger.
I'm sometimes reminded of this story when a patient is describing one of the symptoms of chronic
stress: headaches, indigestion, ulcers, tight muscles, high blood pressure or some combination of
these. When I point out that the symptom is stress-related, the patient seems resigned—stress is
such a constant in most people's lives that all the doors seem to have tigers lurking behind them.
Most of the people who find their way to my office know the fight-or-flight response is hardwired
into our nervous system and many have come to accept a constant feeling of tension as normal,
even inevitable.
It isn't. Like the hero in the story, we have a choice. There is another door, another response to
the challenges of everyday living that is also hardwired into our nervous system. And unlike the
hero, whose destiny rests with chance, we can discover which door is which. A general
understanding of the nervous system and how it responds to stress, coupled with training in
three fundamental yoga techniques, make it possible for us to distinguish one door fron1 the
other. Practicing these techniques gives us the power to choose the lady while leaving the door
that unleashes the tiger firmly closed.
Releasing the Tiger
The autonomic nervous system controls all the body's involuntary processes: respiratory rate,
heart rate, blood pressure, gastric juice secretion, peristalsis, body temperature, and so on. It has
two main components or branches—the sympathetic and the parasympathetic. When we feel
stressed, our brain activates the sympathetic nervous system, which has come to be known as
the fight-or-flight response. This causes the adrenal medulla to secrete adrenaline (also called
epinephrine), a hormone that circulates through the bloodstream, affecting almost every organ.
Adrenaline revs up the body to survive a threat to life and limb: The heart pumps faster and
harder, causing a spike in blood pressure; respiration increases in rate and moves primarily into
the chest; airways dilate to bring more oxygen into the body; blood sugar rises to provide a ready
supply of fuel; some blood vessels constrict to shunt blood away from the skin and the core of the
body, while others dilate to bring more blood to the brain and limbs. The result? A body pumped
up to fight or run, and a mind that is hyper alert.
This response is a crucial reaction to a life-threatening event: when we find ourselves face-to-face
with a mountain lion, the stress response dramatically increases our chances of surviving. And
we’ve all heard stories of fantastic feats: the mom lifting a car off her trapped child, the
firsfighter carrying a man twice his size from a burning building. These are the benefits of the
sympathetic nervous system. Any time we respond quickly and decisively when a life is at stake,
this is the system to thank.
The fight-or-flight response is meant to be triggered sporadically, in those rare moments when
we are actually in peril. Ideally, it remains dormant until the next close call (weeks, months, or
even years later!). But in many of us this response is triggered daily, even hourly. Some people—
soldiers, tightrope walkers, members of a SWAT team, for example—do find themselves in life-

or-death situations frequently. But for most of us, such situations are rare: a mugging, a traffic
accident, a close-up with a bear in the backcountry. Once the threatening event is over, hormonal
signals switch off the stress response, and homeostasis is reestablished.
The problem is that for many of us the fight-or-flight response rarely switches off, and stress
hormones wash through the body almost continuously. The source of our stress is psychological
rather than physical—a perception that something crucial to us is threatened. Fear of the
unknown, major changes in our circumstances, uncertainty about the future, our negative
attitudes—all these are sources of stress. Today we worry more about our jobs, our relationships
or getting stuck in traffic than we do about fighting off a wild animal, but even though the
perceived threat is psychological, it still triggers the archaic survival response.
The upshot is that our bodies are in a constant state of tension, ready to fight or flee, and this
causes a host of physical problems. You can see what some of these are if you look again at what
happens when adrenaline courses through the body: elevated blood pressure, rapid shallow
breathing, high blood sugar and indigestion. What is more, adrenaline makes our platelets
stickier, so our blood will clot quickly if we are wounded. This increases our chances of surviving
a physical injury—but chronically sticky platelets are more apt to clot and create blockages in
our arteries. And this sets the stage for a heart attack or a stroke.
The damage doesn’t end there. When we are constantly in fight-or-flight mode, the adrenal
cortex begins to secrete cortisol, a steroid whose job it is to help us adapt to a prolonged
emergency by ensuring that we have enough fuel. Cortisol acts on the liver and muscle tissues,
causing them to synthesize sugars (glucose) and fats and release them into the bloodstream.
From the body's viewpoint, this is a reasonable response— dumping fat and sugar into the blood
will help us survive a shipwreck, for example. But when this fuel is not metabolized in response
to prolonged physical duress, disease results. Excess sugar in the bloodstream leads to diabetes,
and excess fat to high cholesterol/high triglycerides. Both conditions boost our chances of
developing heart disease.
The steroids cortisol and cortisone quell inflammation in autoimmune diseases and asthma, and
so are useful when used infrequently and for brief periods, but their constant presence in the
bloodstream suppresses immune function. This causes the white blood cells—those hardy
defenders against bacteria, viruses, cancer cells, fungi, and other harmful microorganisms— to
become sluggish. And this makes us more prone to disease, especially cancer and chronic
infections like Lyme disease, hepatitis, and the Epstein-Barr virus.
Sounds grim, doesn’t it? It is. It's a tiger A chronically activated sympathetic nervous system
keeps the body under constant pressure. If we ignore early warning symptoms—tight shoulders,
digestive upset, recurring headaches, an increasing tendency to lose our temper or become easily
upset—sooner or later the tiger will tear us up. But we can make another choice. The autonomic
nervous system has another component, the parasympathetic nervous system. Rather than
living under the tyranny of a ramped-up sympathetic nervous system, we can learn to trigger the
parasympathetic system, the rest-and-digest response, instead.
Just as the fight-or-flight response automatically kicks in at the threat of danger, the rest-and-
digest response automatically responds to our sense of equilibrium. When it is activated, the
heart rate drops, I blood pressure falls, and respiration slows and deepens. Blood flow to the core
of the body is reestablished— this promotes good digestion, supports the immune system and
infuses us with a sense of well-being.

We unconsciously achieve this state on vacation, in the throes of a hearty laugh, or in deep sleep.
1t feels good, and it offers a much needed respite from the hectic pace we set for ourselves. But
we have come to accept stress as the norm and to expect the feeling of relaxed well-being to come
about only sporadically—and so it does. We release the tiger a dozen times a day, even though
the other door is also there in every moment. Once we learn to open it at will, we can override
the harmful habit of triggering our stress response by activating the rest-and-digest component
of our nervous system instead.
Greeting the Lady
I use a variety of natural therapies in my medical practice, but the basic treatments are drawn
from yoga— stretching, breathing, relaxation and meditation—and these techniques are
especially effective when it comes to managing stress. You already know from personal
experience that aerobic exercise is excellent for dissipating stress-created tension, and that
sugar, caffeine and spicy food contribute to jangling your nervous system and shortening your
temper. You are probably also familiar with the relaxing effects of practicing yoga postures - they
teach us to move and stretch our tense, strained bodies and to focus on the breath. But do you
know that breathing slowly and deeply is the easiest way to activate the rest-and-digest system?
That is one reason yoga classes are so popular—they soothe frazzled nerves and quiet anxious
minds. But yoga also works at an even deeper level: it reestablishes healthy breathing patterns,
teaches us to relax consciously and systematically, and gives us the opportunity to explore the
inner workings of our minds through meditation. These techniques, both separately and in
combination, nourish and strengthen the parasympathetic nervous system so that the relax-and-
digest response becomes our normal mode. The fight-or-flight response is then reserved for
emergencies, as nature intended. So let's take a look at some ways we can open Door Number
Two.
Diaphragmatic Breathing • Babies and young children breathe deeply and fully, using the
dome shaped diaphragm that separates the chest and abdominal cavities to move air in and out
of their lungs. Their bellies are relaxed and move in concert with their breath. This is the
natural, healthy way to breathe. But as we grow up we are taught to constrict the abdomen (Pull
your stomach in and stand up straight!), and that training, coupled with an unconscious
tendency to tighten the belly when we experience stress, disrupts the natural flow of our breath.
With the abdomen pulled in, the breath is confined to the upper portion of the lungs (from about
the nipple line up). And because this breathing pattern is perceived by the body to be a stress
response, it reinforces the fight-or-flight reaction.
Diaphragmatic breathing, on the other hand, activates the relax-and-digest response by
stimulating the primary mediator of the parasympathetic nervous system, the vagus nerve. This
nerve travels from the brain to nearly all the thoracic and abdominal organs ("vagus" comes from
the same root as "vagabond"), and triggers a cascade of calming effects. Most of the time we wait
for it to be activated by something pleasant and hope for a trickle-down effect, not realizing that
the nerve (and hence the entire parasympathetic nervous system) can be turned on from the
bottom up by diaphragmatic breathing.
The fight-or-flight response is meant to be triggered sporadically, in those rare moments when
we are actually in peril.
Of all the processes regulated by the autonomic nervous system (heart rate, blood pressure,
secretion of gastric juices, peristalsis, body temperature, etc.), only breathing can be controlled
consciously. And in doing so, we stimulate the branch of the vagus nerve that innervates the
diaphragm (which carries a message to the other vagus branches and the brain) to activate the
www.BeMindful.org Steve Shealy, PhD 813-980-2700
entire rest-and-digest response. This is why the first step in reversing our chronic stress
response is to learn to breathe again the way we were born to breathe.
If you haven't been trained in diaphragmatic breathing, find an experienced teacher and practice
every day until it once again becomes a habit. Then, as you develop the skill of breathing from
the diaphragm in the course of your daily activities, you will begin to experience your breath as a
barometer for the nervous system. As long as you are breathing deeply and from the diaphragm,
you will find that you can access a feeling of calm and balance even when you are confronted
with an unpleasant situation. And you will also notice that if you allow your breath to become
shallow by breathing from your chest, anxiety creeps in, your muscles tighten, and your mind
begins to race and spin. When this agitated breathing is prolonged, it creates an unsettled and
defensive outlook on life. Once you know this from your own experience, you can make a different
choice.
Systematic Relaxation • to activate the parasympathetic nervous system, diaphragmatic
breathing makes an excellent beginning. But we need to do more, particularly when we have
spent years unconsciously flinging open the door to the tiger's cage. Daily periods of relaxation
are a must. When I tell my patients this, many of them say they relax while they watch TV or
read or knit or socialize. The problem is that while these activities distract the mind from its
usual worries (and so provide some relief), they do little to relieve the stress we hold in the form
of muscular contraction and tension.
To reverse well-established habits of holding tension in our bodies, we need to work with what
the yogis call the energy body (pranamaya kosha). Systematic relaxation practices offer a precise,
orderly technique for releasing tension from head to toe. There are a number of these techniques,
and like all yoga practices, they are best learned from an experienced teacher, and then honed
through patient practice. They range in complexity from simple tension/relaxation exercises and
point-to-point breathing practices to techniques that require making fine distinctions among
various points in the energy body. But all involve moving our attention through the body in a
methodical fashion, usually while resting in shavasana (corpse pose). And all require that we
withdraw our attention -from the drama of our lives. For the duration of the practice, we let go of
our memories, plans, worries, and fantasies, and focus on what we are doing here and now as we
move our awareness calmly and quietly from one part of the body to another.
Breathing from the diaphragm, while systematically bringing our full attention to one point in
the body after another, not only releases tension and fatigue in the places where we rest our
attention, it also augments the energy flow among those points. This promotes both healing and
cleansing. Further, because full engagement with a systematic relaxation practice requires that
we clear our minds and attend fully to the present moment, we are also refining a skill that
opens the door to meditation.
Meditation • Since stress begins with the perception that our lives (or at least our sense of
wellbeing) are in danger, working with the mind to alter our perceptions is the most powerful
technique for quieting our stress response. Most of what activates our fight-or-flight response is
not a matter of life or death. We may feel pressured to accomplish a certain task or worried about
what will happen at tomorrow's meeting—but our lives don't depend upon the outcome. With
rare exceptions, the habitual thought patterns that create the experience of stress for us are
overreactions to events in our lives. Instead of responding in a way that floods the body with
adrenaline, however, we can reframe the experience to make it not only less stressful, but also
more accurate in reflecting what is really happening ("I'm only in a traffic jam, I'm not at death's
door.' 'I want to please this person, but if I don't, I'm not going to be fired.") This goes a long way
