Selye

Hans Selye, a scientist known for his research on the effects of stress on the human body, defining the General Adaptation Syndrome.

General Adaptation Syndrome

A three-stage response (alarm, resistance, exhaustion) that the body has to prolonged stress, proposed by Hans Selye.

Exhaustion Stage

The final stage of the stress response, as described by Hans Selye in his General Adaptation Syndrome model, where the body's ability to resist stress becomes depleted after prolonged exposure, leading to increased vulnerability to illness.

General Adaptation Syndrome

A model describing the body's short-term and long-term reactions to stress, consisting of the alarm, resistance, and exhaustion stages.
