General adaptation syndrome (GAS) is a physiological response to stress that occurs in three distinct phases: the alarm response, resistance, and recovery.

During the alarm phase, the body recognizes a threat and initiates a fight-or-flight response, resulting in the release of stress hormones such as adrenaline and cortisol. This prepares the body to respond to the stressor.

In the resistance phase, the body adapts to the stressor. It continues to maintain heightened alertness and physiological arousal to fend off the effects of the stress while striving to return to a state of homeostasis. If the stress persists, the body's resources begin to deplete, leading to potential fatigue or burnout.

Finally, the recovery phase occurs when the stressor is removed, allowing the body to return to normal function and recuperate. In this phase, recovery may involve physical, emotional, and mental restoration.

Understanding these phases is crucial for recognizing how prolonged stress can impact health, which is particularly relevant for those studying emergency medical services, where stress can be a significant factor in the field.
