One
of the pioneers of stress research, Dr. Hans Selye wrote that "
... stress is essentially reflected by the rate of all the wear
and tear caused by life."
His
research convinced him that the body has only a finite reserve of
adaptation energy to apply to the stressors of life. Selye likened
this reserve to a bank account upon which we can make withdrawals
from time to time but into which we cannot make deposits. It is
a non-renewable reserve of energy which we draw on throughout life
until eventually it is consumed and death results. Some people squander
their reserves and experience premature ageing as a result; others
exercise more discretion and so they maintain a supply over a longer
period of time.
Over
a long period of time the stress response begins to take a toll
on the body. One of the prime targets affected is the thymus gland
(a mysterious pale grey gland that sits behind the breastbone, above
the heart) which plays a key role in the body's immune system. The
thymus gland pumps out millions of lymphocytes each day to patrol
throughout the body and to kill off bacterial invaders. Killer cells
called macrophages literally eat invading bacteria. They operate
in all parts of the body and we depend on them for our survival.
Macrophages are weakened by a steroid called cortisol which is released
by the adrenal gland when we experience stress. A weakened immune
system makes us vulnerable to infection and this is why people under
stress often experience regular attacks of colds and flu.
Psychological
stress does have physical ramifications. We can do ourselves a great
deal of harm by stressful thinking. We can flood our body with stress
hormones and this can create a vicious cycle making us more and
more stressful.
