Where does the fight or flight response belong in the stages of General Adaptation Syndrome?

The fight or flight response is primarily associated with the first stage of General Adaptation Syndrome (GAS), known as the alarm reaction stage. This initial response occurs when an individual perceives a threat, triggering the body's immediate physiological reactions, such as increased heart rate and adrenaline release. This prepares the body to either confront or flee from the danger. If the stressor persists, the body may move into the resistance stage, where it attempts to adapt to the ongoing stress.
