Health and Stress
Health Psychology – studies how biological, psychological and social factors influence health, illness and treatment.
- large number of people
- Patterns (correlations) between lifestyle and health outcomes
- look for risk factors of disease.
Top 5 causes of Death are related to Lifestyle
Stressors: Events or situations that are perceived as harmful, threatening, or challenging and thus trigger stress response.
Stress –play role in 50% to 70 % of all physical

- any change, whether negative or
positive is inherently stress producing.
or mental health.
Daily Hassles Scale
Social/cultural Stressors: poverty, low social status, discrimination
Conflict as a source of Stress
Approach-Approach conflict – win/win
easily resolved and not too stressful
People feel stuck and experience
Stress and anxiety.
Physiological Stress Response
Triggered whenever your mind determines that
you are under threat. Response is the same
regardless of the type of stress!
Fight-or-flight response (Cannon)—rapidly occurring chain of internal physical reactions that prepare people to either fight or take flight from an immediate threat
- activates Sympathetic Nervous System (SNS)
Heart rate, BP, release of epinephrine,
adrenaline, and endorphins.
Increases general arousal level
and reduces concentration.
Net loss of amino
Glucocortical Stress Hormones
epinephrine and norepinephrine
Short term elevation (20 to 60 mins)
Triggers fight or flight response
Reduced inflammation and enhance tone of circulatory system.
In long run they weaken important systems, lower immunity and lead to illness.
Prolonged stress also linked to depression & other psychological symptoms.
General Adaptation Syndrome (GAS)
Stage 1. Alarm
- SNS response.
- good for short term stressors, but when
prolonged . . .
Stage 2. Resistance
- prolonged period of moderate arousal
- continued high levels of hormones that elevate
blood sugars -- increase metabolism
- increase immune response
Stage 3. Exhaustion
- prolonged metabolic increase decreases
Alarm Resistance Exhaustion
Student Syndrome – students more likely to get sick after exam period.
Burnout - psychological, physical and behavioral
dysfunction in response to continuous, chronic
Shortening of Telomeres
normally occurs with age.
Stress appears to increase the rate of shortening!
Stress does age people.
Presidents actually tend to
live pretty long: WHY?
Access to superior medical
care, good education, and it
takes an inherently healthy
person to endure the rigors of a presidential campaign and administration.
Stress and Illness
SNS is a direct link between CNS and the physical systems of the body.
Stress and the Immune System
Lymphocytes – white blood cells that fight
viruses and bacteria
Lymphocytes have receptors for neurotransmitters and hormones AND they also produce these chemical messengers.
Problems develop when the immune system is either underactive or overactive.
Underactive - does not protect against disease.
Overactive – Immune system may attack one’s own body tissue.
Woman have stronger immune systems than men. Also more susceptible to autoimmune disorders!
Personality, Stress and Illness
Type A - competitive, workaholic, impatient, quick to anger.
Type B - less competitive, easy-going, less hostile
Cynical Hostilityis the most predictive Type A behavior for Heart Disease.
Type A individuals are more susceptible to negative effects of stress, including vulnerability to heart disease, with anger and hostility being primary factors.
How Do You Deal with Stress?
Components of Stress Reactions
Stress Coping Techniques
1) Assess Stressors
- reduce those you do not need.
2) Cognitive Appraisal
- Sense of Control
- Predictability - plan to cope
- time management
3) Work on your reaction to Stress
Optimism!! Positive outlook
unstable (temporary) and specific.
- commitment to activities
- see their activities as worthwhile
- see potential stressors as a challenge
- sense of control
4) Social Support
5) Journal Writing
6) Aerobic Exercise!
Moderate exercise adds
two years to your life!
Text lists many benefits – but misses one.
That physical exertion often tricks the SNS into thinking that the threat is over -- Turns off fight or flight response!
Taking one’s mind off problems can help when the stressor involves a waiting period (i.e., did I get the job) but if it is distracting for coping with the stress, it can make it worse!
The SNS is part of the autonomic system.
We do not have voluntary control over it.
We do however have indirect control.
Components of Relaxation
Control of Breathing
- changes SNS response
Imagery – Nervous system
responds to imagery the same
way it does to reality. Calming
thoughts and images activate
PNS turning off Fight or flight
- systematic tensing and relaxing of muscle groups
