Health
Health is a state of being free from illness or injury. Health is intimately tied to behavior and mental processes. (physical, mental, and emotional wellbeing)
Health Psychology
Health psychology is the study of how psychological factors (like stress) affect health and illness. Health psychology also includes the study of how interventions help maintain health and combat illness.
Health Psychologists
Who study how people’s behaviors influence their health, have classified stressors into several types
Leading Causes of Death in Adults
Heart disease - chronic
Cancer - chronic
Chronic lower respiratory diseases - chronic
Unintentional injuries
Stroke
Alzheimer’s disease
Diabetes
Influenza and pneumonia
Kidney disease
Suicide
What behaviors contribute to health
Maintain healthy weight
Exercise regularly
Eat a healthy diet
Get 8 hours of sleep
Quit smoking (or never smoke)
Behaviors that contribute to chronic conditions
Excessive alcohol consumption
Tobacco smoking
Unhealthy diet
Inadequate exercise
Inadequate sleep
Stressors
Stimuli in our lives that we perceive as challenges or threats (Stressors are stimuli that place demands on us and require us to adapt in some manner)
Reactions
Second part in the process of stress response (includes bodily reactions)
Coping
By perceiving and then reacting, we are coping with the challenges or threats (successfully/not)
Cognitive Appraisal
Is it irrelevant, stressful, or positive
Is this a threat, harm, or challenge
Challenge = better; threat = worse
Various sources of stressors
Major life events
Catastrophes
Daily hassles
Frustration
Pressure
Conflict
Degrees of stressors
Microstressors
Major negative events
Catastrophic events
Microstressors
Daily hassles and minor annoyances (traffic jam, line at the grocery store, etc)
Major negative events
Personal, negative events (divorce, death of a loved one, serious illness, etc.)
Catastrophic events
Tend to occur unexpectedly and affect large numbers of people; affect both physical and mental health (hurricane, tsunami, wildfire)
Fight or Flight response
Sympathetic division of the autonomic nervous system
Release of adrenaline, norepinephrine, cortisol
Affects multiple body systems; suppresses immune system
General Adaptation Syndrome
Our stress response system defends, then fatigues (The body’s resistance to stress can only last so long before exhaustion sets in)
Phase one of GAS
Alarm reaction (mobilize resources)
Phase 2 of GAS
Resistance (cope with stressors)
Phase 3 of GAS
Exhaustion (reserves depleted)
Diseases of Adaptation
Chronic inflammation
Damage to heart and blood vessels
High blood pressure, heart disease
Depressed immune function
Colds, flu
Arthritis
Disruptions in gut bacteria
HPA Axis
Hypothalamus, pituitary gland, adrenal gland axis
Effects of chronic stress
More vulnerable to infectious diseases (colds and flu)
Progression of HIV infection to AIDS is influenced by stress
Produces greater vulnerability to the virus responsible for mono, which is normally kept in check by the immune system
Stress related to social relationships can be especially harmful to our ability to stay healthy
Heart disease is associated with chronic stress (damage affects the ability of blood vessels to expand when necessary)
PTSD
Severe negative reactions to a traumatic event, including anxiety, irritability, jumpiness, inability to concentrate or work productively, dysfunction in many areas of life (thinking, sexual function, relationships, sleep)
