Stress part one
- Reaction
- Autonomic nervous system
governs the bodily functions
that need to be automatic.
- Sympathetic branch gets body ready
for fight or flight. Makes us more
alert and gives us more energy.
- 1) Hypothalamus
stimulates the adrenal
medulla. 2) Adrenaline is
released. 3)the body is
ready for fight or flight.
- Acute stress
- Physiological
reactions include
increased heart
rate and increased
blood pressure.
- 1) Hypothalamus
stimulates the adrenal
medulla. 2) Adrenaline is
released. 3)the body is
ready for fight or flight.
- Parasympathetic branch. Rest
and digest. when our body is in
a relaxed state and functioning
normally. low levels of
adrenaline.
- 1) Hypothalamus stimulates the
pituitary gland to release ACTH-
adrencorticotrophic hormone.
2) Stimulates the adrenal cortex.
3) releases corticosteroids.
- Chronic stress
- Liver releases energy
and the immune
system is supressed.

- Stress and Illness
- Natural immunity provides
immediate response to foreign
invaders
- white blood cells
give natural
immunity
- effected more than
specific immunity
- white blood cells
give natural
immunity
- Specific immunity occurs
when our lymphocytes
produce antibodies to
eliminate specific antigens.
- less affected by stress
as memory of white
blood cells is not
affected.

- Selyes general
adaption syndrome
- Animal study giving rats
daily injections. they started
to develop stress related
symptoms. ALARM,
RESISTANCE and
EXHAUSTION!

- Natural immunity provides
immediate response to foreign
invaders
- Illness research studies
- Cohen et al wanted to
see whether people
with high stress levels
were more likely to get
ill than those with low
levels.
- 394 participants
asked questonaires
about stress levels
- A nasal drip either
exposed them to
the common cold or
a saline soloution.
- 82% became
infected which
positively correlated
to levels of stress.
- long term stress
leads to illness
- X social desirability- self report
X ethical issues
- 394 participants
asked questonaires
about stress levels
- Kiecolt Glaser et al
investigated whether the
stress of sitting an exam
has an effect on the
functioning of the
immune system.
- 75 medical students
had blood samples
taken from them one
month before the exam
(low stress) and during
the exam (high stress).
- T-cell activity was
measured (essential for
immunity).
- T-cell activity was
lower in the
second sample.
short term stress
leads to illness.
- 75 medical students
had blood samples
taken from them one
month before the exam
(low stress) and during
the exam (high stress).
- Cohen et al wanted to
see whether people
with high stress levels
were more likely to get
ill than those with low
levels.
- Holmes and Rahes SRRS =
The social Readjustment
Rating Scale
- Rahe investigated
whether scores on the
SRRS correlated with the
subsequent onset of
illness.
- 2,500 male american sailors
- SRRS assessed how
many life events they'd
experienced in the
previous six months.
- Over 6 months of tour
duty records were kept
of health status
- Positive correlation between life
change scores and illness scores.
as life change units increased, so
did the frequency of illness.
- 2,500 male american sailors
- Rahe investigated
whether scores on the
SRRS correlated with the
subsequent onset of
illness.
