The general adaptation syndrome describes stages in stress response. A stressor acts on the body, triggering the alarm reaction. This is followed by the resistance stage, where the body attempts to cope with the stressor. If the stressor persists, the exhaustion stage sets in, characterized by depletion of resources and increased vulnerability to illness.
The 3 Stages of the General Adaptation Syndrome
The general adaptation syndrome (GAS) is a three-stage model of the body’s response to stress. It was first proposed by Hans Selye in 1936. According to Selye, the GAS is a nonspecific response to any stressor, whether it is physical, emotional, or psychological.
The Three Stages of the GAS
The GAS is divided into three stages:
-
Alarm stage. This is the first stage of the GAS, and it occurs when the body is first exposed to a stressor. During this stage, the sympathetic nervous system is activated, which causes the release of hormones such as adrenaline and cortisol. These hormones prepare the body for a fight-or-flight response.
-
Resistance stage. This is the second stage of the GAS, and it occurs when the body has adapted to the stressor. During this stage, the sympathetic nervous system is less active, and the body begins to repair itself.
-
Exhaustion stage. This is the third stage of the GAS, and it occurs when the body has been unable to cope with the stressor. During this stage, the sympathetic nervous system is exhausted, and the body becomes vulnerable to illness and disease.
Table of the Stages of the General Adaptation Syndrome
| Stage | Description |
|---|---|
| Alarm stage | The body is first exposed to a stressor. |
| Resistance stage | The body has adapted to the stressor. |
| Exhaustion stage | The body has been unable to cope with the stressor. |
How to Manage the GAS
There are a number of things you can do to manage the GAS and reduce its negative effects on your health. These include:
- Identifying and avoiding stressors
- Developing coping mechanisms
- Exercising regularly
- Eating a healthy diet
- Getting enough sleep
Question 1:
What does the general adaptation syndrome describe?
Answer:
The general adaptation syndrome describes stages in the body’s response to stress.
Question 2:
What are the key concepts of the general adaptation syndrome?
Answer:
The key concepts of the general adaptation syndrome are the alarm reaction, resistance, and exhaustion stages.
Question 3:
How does the general adaptation syndrome relate to health outcomes?
Answer:
The general adaptation syndrome can affect health outcomes by influencing the body’s immune response, cardiovascular function, and other physiological processes.
