General adaptation syndrome (GAS) is a theory that describes the physiological changes the body experiences when under stress. The syndrome includes three stages: the alarm stage, the resistance stage, and the exhaustion stage. Show
The first GAS stage contains two substages:
Following the alarm stage, the body begins to repair itself. If the stressful situation is resolved, the body continues to repair itself until it returns to its pre-stress state. If the stressful situation is not resolved, the body remains on high alert, eventually adapting to the higher stress level. Stress hormones and blood pressure remain elevated. This can lead to hypertension and heart problems as well as irritability, frustration, and poor concentration. This stage occurs during prolonged or chronic stress when the body’s adaptation to higher stress levels starts to break down. The body no longer has the strength or resources to fight the stress. Signs of the exhaustion stage include, but are not limited to, the following:
For short-term or mild stressors, the alarm stage is not harmful. It is a natural mechanism that is designed to protect the body from danger. However, when prolonged or chronic stress is experienced, the body may not be able to repair itself in a timely manner, which can lead to the exhaustion stage. Understanding the stages of GAS can help with the identification of personal stress signals, which can help with the reduction of stress levels. The fight-or-flight response (also called the stress response) is a physiological reaction that occurs in response to a perceived threat or danger. This enables the body to take action quickly, and is intended to keep us out of (physical) harm’s way. Unfortunately for our health, this response also occurs when we are not in any immediate physical danger, but are still experiencing stress. For example, this can happen when someone is running late for an appointment or class, and is feeling stressed about trying to get there. The physical changes that occur during this response can cause wear and tear within the body if the perception of stress persists. Here are a few examples of such bodily changes:

General Adaptation SyndromeStages of the General Adaptation Syndrome Homeostasis is a state of physiological calmness or balance, and occurs when our bodily functions are running smoothly in conjunction with low stress levels. When exposed to stressors, this causes an imbalance to occur as the body responds to the perceived threat, and then tries to return to normal functioning. The general adaptation syndrome (GAS), developed by Hans Selye, describes the pattern of responses that the body goes through after being prompted by a stressor. There are three stages: alarm, resistance, and exhaustion.
These changes will occur in the body regardless of whether the perceived stressor is considered eustress (positive or pleasant) or distress (negative or unpleasant). Ultimately, this means that we need to take active steps in managing all of our stressors, as it can build up and potentially cause harm to our health otherwise. What physiological events may happen in the alarm phase of general adaptation syndrome?Your heart rate increases, your adrenal gland releases cortisol (a stress hormone), and you receive a boost of adrenaline, which increases energy. This fight-or-flight response occurs in the alarm reaction stage.
What is the alarm stage of the general adaptation syndrome?At the alarm reaction stage, a distress signal is sent to a part of the brain called the hypothalamus. The hypothalamus enables the release of hormones called glucocorticoids. Glucocorticoids trigger the release of adrenaline and cortisol, which is a stress hormone. The adrenaline gives a person a boost of energy.
What are the 3 stages of general adaptation syndrome?General adaption syndrome, consisting of three stages: (1) alarm, (2) resistance, and (3) exhaustion. Alarm, fight or flight, is the immediate response of the body to 'perceived' stress.
What are the stages of the general adaptation syndrome the body's response to stress?General adaptation syndrome is how your body responds to stress. There are three stages to stress: the alarm stage, the resistance stage and the exhaustion stage.
