Studies relationships between psychological factors, especially stress, and the workings of the immune system
Americans report feeling fatigued, achey (head), a loss of appetite, etc when stressed
Endocrine system

The body’s system of defense against disease
Leukocytes - white blood cells - immune system’s foot soldiers
Antigens
Invading pathogens
Antibodies
Specialized proteins that lock into position on an antigen, marking it for destruction by specialized “killer” lymphocytes that act like commandos on search and destroy missions
General adaptation syndrome (GAS)

If your body believes you cannot overcome the danger but can avoid it by running away, you’ll respond ini flight mode
A surge of hormones, like adrenaline, give your body the stamina to run from danger longer than you typically could

This response happens when your body doesn’t think doesn’t think you can fight or flight
Parasympathetic
fawn
The fawn response is your body’s emotional reaction that involves becoming highly agreeable to the person abusing you
General Adaptation Syndrome
alarm reaction
resistance stage
exhaustion stage
Alarm reaction
Resources arise to confront a stressor
Perception of an immediate stressor triggers this
Mobilizes the body to prepare for challenge or stress
Resistance stage
Remains high and attempts to adapt
Adaptation stage
Body trees to renew spent energy and repair damage
Exhaustion stage
Resources depleted – parasympathetic dominance
Exhaust bodily resources
Characterized by dominance of the parasympathetic branch of the ANS

People who experience a greater number of life changes are more likely to suffer from psychological and physical health problems than those with fewer life events
