 Homeostasis- The body’s balanced state
 Eustress- Good stress
 Distress- Bad Stress
 Duration/Degree Duration= the amount of time our body’s physiology varies
Degree=Condition or the amount of physiological variance
Walter Cannon- Harvard Medical School
 First to describe the effects of acute stress
 Termed this stress reaction as the fight-or-flight
response
 A primitive response that quickly increases heart rate,
respiration, blood pressure, and serum cholesterol
Acute Alarm Reaction
 Body prepares for fight or flight
 Time of emergency
 Heart pumps blood faster and with greater force
 Blood pressure elevates abruptly
 Lungs send more oxygen to muscles
 Faster blood clotting
Acute Alarm Reaction
 Widening of the pupils to admit more light in order to
heighten visual acuity and awareness
 Increase in breathing rate
 Endorphins released – decrease in body’s sensitivity to
pain
 Elevated blood sugar levels
Hans Selye
 Studied the effects of long-term (chronic) stress
 Stress is- “The nonspecific response of the body to any
demand made upon it”
 Summarized his findings by proposing a three-phase
process called the general adaptation syndrome
 alarm reaction
 stage of resistance
 stage of exhaustion
Other Influential Researchers

 Psychosomatic disease
 Benson
 Relaxation response
 Vogt

 Jacobson
 Progressive relaxation
Stress Theory
 Several theories explain the causes of stress:
 Holmes and Rahe- Life events theory: stress occurs when
the situation requires more resources than are available
 Kobasa and colleagues- Hardiness theory: one’s attitude
toward the events determines stress, not the event.
 Social support theory: insufficient social support for
responding to event
Fight or flight response

 A situation can be stressful or not -- it all depends on
your perception of the event
 A response to stress can be effective or not -- it
depends on your resources and coping strategies
