Physiological stress responses mobilise body resources through the fight-or-flight pathway and HPA axis

The sympathetic nervous system triggers fight-or-flight: heart rate increases, blood redirects to muscles, digestion slows, pupils dilate.
The hypothalamic-pituitary-adrenal (HPA axis) releases cortisol, maintaining high blood glucose and suppressing immune function during acute stress.
Selye's General Adaptation Syndrome (GAS) describes three phases: alarm (initial response), resistance (adaptation), and exhaustion (resources depleted).

Example

A student facing an exam experiences alarm (racing heart, anxiety), resistance (focusing energy on studying), and exhaustion (burnout if stress continues unabated).

Chronic stress damages health through sustained HPA activation and immune suppression

Prolonged cortisol elevation increases infection risk, impairs wound healing, and worsens inflammatory conditions like asthma and arthritis.
