  • 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
