STRESS!!!!
FEELING STRESSED OUT?
 How often do you experience stress in your
daily life? Never? Rarely? Sometimes?
Is it frequent?
In a 2007 Gallup Poll over half of the people
under the age off 55 said that they did not
have enough time to do the things that they
wanted to do.
SEINFELD
 Studies of stressors have shown that
people’s number one fear is speaking in
public.
 Second to this is the fear of dying. Citing
this finding, comedian Jerry Seinfeld has
joked that people are more afraid of giving
the eulogy at a funeral than being in the
casket.
What is Stress?
Stress: the process by which we
perceive and respond to certain
events called stressors, that we
appraise as threatening or
challenging.
Stress comes in 2 Types
Distress
 Stress perceived as being
negative—those events we
typically think of when we
think of “stress.”
Eustress
 Stress perceived as being
positive, but which still
carries heightened arousal.
With both types of stress…
They can (over time) lead
to harmful physical
effects, even
though eustress is more
pleasant to endure.
One Key in Understanding Stress
 Stress is not just a stimulus or a response. It is the process by
which we appraise and cope with environmental threats and
challenges. Stress arises less from events themselves than
from how we appraise them.
 For example—a creaking sound in an empty house may cause
stress in one person and NOT in another.
STRESS AND HEALTH
Experiencing prolonged stress can
lead to chronic disease. Those who
came back from Vietnam with
PTSD went on to suffer greatly
elevated rates of circulatory,
digestive, respiratory, and infectious
diseases.
GENERAL ADAPTATION SYNDROME
 Concept of the body’s adaptive response to stress in three
phases—alarm, resistance, and exhaustion.
1) Alarm Reaction: sudden activation of sympathetic nervous
system. Heart rate zooms, Blood is diverted to skeletal muscles.
You feel the faintness of shock.
2) Resistance:Your temperature, blood pressure , and respiration
remain high. Sudden outpouring of hormones.
This is draining and leads to…
3) Exhaustion: Makes you more vulnerable to illness and possibly
death.
