Q

why do we get chills when we have a fever?

A
  • core temp < thermostat setting = feels chilled
  • Chills = generate more internal heat - shivering, vasocontricting skin and turnin goff sweat glands

Q

how can fevers be good?

A
  • disrupts growth and reproduction of many invasive pathogenic microorganisms, both bacterial and viral
  • lower amount of iron available to invading bacteria, which have a higher iron requirement
  • enhances neutrophil migration, T-Cell proliferation, and interferon activity
