What are the three distinct stages of the General Adaptation Syndrome?

The General Adaptation Syndrome (GAS) is a model that describes the body's short-term and long-term reactions to stress. The correct stages are Alarm, Resistance, and Exhaustion.

In the Alarm stage, the body recognizes a stressor and initiates a physiological response, activating the fight-or-flight response, which prepares the body to confront or flee from the stressor. This involves the release of stress hormones like adrenaline and cortisol, leading to heightened alertness and energy.

In the Resistance stage, the body attempts to adapt to the ongoing stressor. During this phase, physiological responses are still in effect, but the body starts to stabilize and tries to return to homeostasis while continuing to respond to the stressor. This stage can last for a prolonged period, depending on the nature of the stressor and the individual's coping abilities.

Finally, the Exhaustion stage occurs when the body's resources become depleted after prolonged exposure to the stressor. If the stress continues beyond the body's capacity to cope, it may lead to increased vulnerability to illness, burnout, and significant changes in health.

This conceptual framework provides insight into how chronic stress can impact both mental and physical health, making it a foundational concept in psychology and medicine.
