General Adaptation Syndrome

A three-stage process that describes the physiological changes the body goes through when under stress: alarm, resistance, and exhaustion.

Alarm Reaction

The first stage of the GAS, which is triggered by the impact of a stressor and characterized by sympathetic activity.

Exhaustion Stage

The final phase of the stress response, as described by Hans Selye, characterized by depleted physical and mental resources, leading to burnout or health issues.

Resistance Stage

The second phase of the General Adaptation Syndrome, where the body mobilizes its defenses to cope with a stressor.
