General Adaptation Syndrome (GAS) is a model of the body's physiological response to stress. It was first proposed by Hans Selye, a Hungarian-Canadian endocrinologist, in the 1950s. According to this model, the body goes through three stages in response to stress: the alarm stage, the resistance stage, and the exhaustion stage.

The alarm stage, also known as the "fight or flight" response, is the body's initial reaction to stress. During this stage, the body releases stress hormones such as adrenaline and cortisol to increase the heart rate, blood pressure, and other physiological functions needed to respond to the stressor. This helps the body to be better prepared to handle the stressor and cope with the situation.

The resistance stage follows the alarm stage. During this stage, the body tries to adapt to the stressor and maintain homeostasis, or balance. The body continues to produce stress hormones, but at a lower level than in the alarm stage. If the stressor persists, the body may continue to be in the resistance stage for a longer period of time.

The exhaustion stage is the final stage of GAS. If the stressor persists or the body is unable to adapt to it, the body's resources will eventually become depleted, leading to the exhaustion stage. During this stage, the body's ability to cope with stress is reduced, and the individual may experience physical and emotional symptoms such as fatigue, illness, and depression.

It is important to note that not all individuals will experience all three stages of GAS, and the length of each stage can vary. Additionally, different stressors can affect individuals in different ways, and some individuals may be more resilient to stress than others.

In conclusion, GAS is a model that describes the body's physiological response to stress, which consists of three stages: the alarm stage, the resistance stage, and the exhaustion stage. Understanding this model can help individuals recognize the signs of stress and take steps to manage it effectively.
