The
Chemistry of Stress
How does stress arise?
Whenever we perceive a situation that
demands urgent and
immediate action, our adrenal glands begin to make adrenalin. Imagine a mad
dog chasing us....the fear in our mind is transmitted to the brain and
the pituitary gland in the forehead sends signals to the adrenal gland
situated above the kidney to produce the hormone adrenalin. The adrenalin
is like a siren, an alarming sound to inform everyone about a situation
demanding immediate attention and to halt all other activities. Within a
few seconds the adrenalin instructs various organs like the heart to
pump more blood, the muscles to get tensed, the eyes to dilate, the
lungs to breathe more; in the meantime, glucose is pumped into the blood,
which thickens. Within a few seconds, so much glucose is made
available in the blood, that we could run even a mile.
Stress - an Unwarranted Condition
This type of adrenalin-mediated reaction is good, even necessary, to handle an
attention-demanding situation and protects the body. But this
adrenalin secretion which is meant only for combating emergency situations,
if triggered unnecessarily like maybe for an unwanted telephone call, a traffic jam,
or kids quarreling while watching TV, an irritating boss, spouse or a
colleague etc. is called stress. The above unwarranted reactions if
triggered in our body will make our organs work overtime and exhaust
themselves.
Understand that under normal conditions your heart beats more than 60 times a
minute. Under stress, you make your heart pound more than 100
times a minute. This will tire your heart and end up in a heart
attack and/or changing of heart valves.
Stress Reactions
The
digested food is converted to glucose in our bodies and excess glucose is
stored as glycogen or fat. Excess glucose in the blood will damage the body
organs. Therefore, a hormone called insulin that is produced by the pancreas will
remove excess glucose from the blood.
We have to understand the following fact to maintain good health. The
energy needed to run to a response to 'fear and flight' is made available by
adrenalin by increasing glucose level in the blood. So when we
unnecessarily increase the blood glucose levels it damages
the body organs. This is how stress, over a period of time, causes quick ageing
and age-related diseases.
You will realize that this 'fight or flight' response is a
high energy process. We might wonder
where the extra energy comes from, especially if we were feeling tired
immediately before the event that caused the 'fight or flight' response in
us. The answer
is that energy is diverted from the body’s normal functions of maintenance
and repair. Thus, so long as we are feeling stressed, our digestion,
rejuvenation and cleansing functions are turned off.
Worn out by the process described above, our energy is sapped. We lose
concentration, become easily confused, make silly mistakes, fall asleep
after lunch, become irritable, find it hard to sleep at night, don’t want to
wake up in the morning, sweat more than normal, and/or suffer from headaches.
These are the symptoms that ring bells of the disaster we are causing
our body.
Instead of addressing the root cause of "low
energy" we get into addictive habits.
