Stress has been defined in many ways:
# Dr.
Hans Selye: (Father of modern Stress theory) “the
non-specific response of the body to any demand made upon it”.
# Lazarus: “The response of the body when pressure exceeds ones
perceived ability to cope”.
In
any situation, the primary impulse is sent to the amygdala, a
small pea sized organ behind the eyes and over the nostrils for evaluation of
threat. When the amygdala perceives threat, it sends an impulse to the hypothalamus
which in turn transmits the threat to the sympathetic nervous system through
the pituitary gland. This input floods the
circulatory system with adrenaline.
The body responds by:
- Increased Heart rate & blood pressure: To get more blood to muscles & brain.
- Faster breathing: To increase oxygen inflow into the body.
- Dilation of blood vessels in muscles: Preparing for action.
- Dilation of the eyes and sensitivity of the sense organs: To assess the situation and act quickly.
- Auditory exclusion & tunnel vision.
- Inhibition of erection.
- Decreased blood flow to skin/ digestive tract/ kidneys & liver to divert blood to musculo-skeletal system.
- Increased level of blood sugar, fats and cholesterol: For extra energy.
- Increased level of platelets and blood clotting elements: to prevent hemorrhage in case of injury.
How can this be explained in Yoga terms?
In the previous post, we have seen that when
we receive a stimulus, we either like or dislike it. Depending on whether we like (raag) or dislike (dwesh) the stimulus, we draw close to the subject or away from it.
This action of moving close to or away is karma (action).
How do we like or dislike a subject? Like or
dislike is personal and we evaluate against a standard called svadharma (sva= self + dharma = conditioning) which is
uniquely our own. Dharma or conditioning occurs on account of our
DNA, family, upbringing, societal norms, diet and habits. The behaviour
exhibited by us on account of our svadharma is called svabhaava (sva= self + bhaava = manner or behaviour). Together they present
to the outside world our identity and the weave of svadharma and svabhaava is called svatantra (sva = self + tantra = weave).
What happens after the threat passes?
Lessons are stored in the amygdala for future use; the experience changes our personal values (svadharma) on account of our awareness
of the stimulus (vijnana) and its impact on our identity (jnana) and this consequently
reflects as changes to our behavior.
Often, we are able to manage some parts of the
situation, but not all elements. Also, there may not be enough time, or our conditioning may lack the capability
to find a solution. This leads to sustained perception of threat and we begins
to experience physical, intellectual or emotional discomfort.
Finally, the body which has gone into a state
of alert now needs to come back to normal. This may be possible if there is
enough time for the system to assimilate the learning and work out the
adrenaline. But, we often find ourselves confronting multiple situations with
different coping requirements in each situation which results in prolonged
states of arousal that, over time, damages the body.
The chemicals released by the pituitary, the
adrenals, the hypothalamus, the thyroid etc., are life-saving chemicals that
inhibit routine functions to provide the drive to face danger. Prolonged
exposure to these chemicals damages vital organs, leading to reduced resistance
of the immune system, hypertension, psychiatric illnesses, and stomach
ailments, etc., which over time result in other psychosomatic problems that
affect different parts of our body.
Indicators of Stress
Physical: fatigue,
headache, insomnia, muscle aches/stiffness (especially neck, shoulders and low
back), heart palpitations, chest pains, abdominal cramps, nausea, trembling,
cold extremities, flushing or sweating and frequent colds.
Intellectual: Decreased
concentration and memory, indecisiveness, mind racing or going blank,
confusion, loss of sense of humor.
Emotional: anxiety,
nervousness, depression, anger, frustration, worry, fear, irritability,
impatience, short temper, nervousness (nail-biting, foot-tapping), increased
eating, yelling, swearing, blaming.
Anecdotes, experiences and
situations to help understand…
Given below are a series of situations. Some
are motivational situations, others distressing while some boring. Decide
whether you would experience stress in these situation and give them weights
between 0 and 5 on the impact they would have on you… for example - Stress on the day of
marriage. Most would experience a mix of motivation and anxiety. Let us assume
that the resultant stress experienced =2. Similarly, assess the resultant
stress one would experience in the situations below;
- Stress on the day of exams.
- Stress on the day of the results of the exams.
- Stress of having got good marks.
- Stress of having got poor marks.
- Stress of getting admission into a college.
- Stress of losing a job.
- Stress of argument with one’s best friend.
- Stress of hunger.
- Do animals experience stress? Stress which a pet experiences when seeing the master leave for work.
- Stress that a pet experiences when master returns from work.
- Is earthquake a result of stress between 2 plates?
