    • SAM system triggered
    • secondary response- HPA system
    • The hypothalamus releases CRH which stimulates the adrenal cortex which releases cortisol
    • Lowers sensitivity to pain
    • Releases glucose for energy- not digesting properly
    • Lower immune system
    • Reduces recall potentially
    • Immunosuppression - immune system seen as non-essential shuts down to divert energy elsewhere, risk of illness.
    • Kiecolt-Glaser- measuring NK cell activity (immune system) during exam period and month prior in 75 medical students and did SRRS, high SRRS score had lower NK cell activity
    • If cortisol levels suddenly drop may become ill, inflammatory effects because it reduced it when active
    • Can't prove cause and effect
    • Bad habits have bad effects
    • Lack of longitudinal study
    • Boys have more cortisol activation
    • CRH --> pituitary gland --> ACTH --> Adrenal cortex
