Stress is experienced when a person's perceived demands exceed their perceived
ability to cope. Stress is an alarm reaction that involves a series of changes in the body.
A stressor is something that triggers the stress reaction in the body and it can include
workplace and life events. Stressors can vary from person to person depending on their
sense of control.
The Body's Response
The Sympathomedullary Pathway (SAM) ­ Is the body's response to short term
(acute) stressors.
When there's a stressor in the environment signals are sent to the hypothalamus, which
triggers activity in the autonomic nervous system (ANS). This then triggers the adrenal
medulla and as it becomes more active and uses more energy it stimulates the release
of adrenaline and noradrenalin.
Adrenaline and noradrenalin help prepare you for the fight or flight response by...
Increasing blood pressure and heart rate
Tensing muscles
Increasing breathing
Suppressing nonemergency processes such as digestion
The PituitaryAdrenal System (PAS) ­ Is the body's response to long term (chronic)
If the stress is long term, it will start to use up your body's resources so a counter shock
response supplies your body with fuel.
The hypothalamus is triggered at the sight of a stressor, which controls most of the
body's hormonal systems. Activation of the hypothalamus triggers the release of CRF
into the pituitary gland which releases the hormone ACTH stimulating the adrenal cortex
which in turn releases corticosteroids such as cortisol.
The cortisol has physiological effects on the body, which replace the energy used up by
the body's initial reaction to stress.

Daily Hassles
Daily hassles are everyday issues such as being late for work or missing the bus that
cause us stress. The negative effect of daily hassles can be counteracted by daily uplifts
such as a compliment. However, daily hassles can accumulate, if you experience too
many in one day, which can create serious stress problems such as depression.…read more

such as the heart are not stimulated for the fight or flight response.…read more
