The Adrenal Glands
Captions available
The idea
The adrenal glands release epinephrine and cortisol, mobilizing the body's response to stress.
In practice
Cortisol rises within minutes of a threat and remains elevated long after the threat has passed.
Where people slip
Cortisol is not a damage signal. It is a mobilization signal whose damage comes from staying elevated.
