General Adaptation Syndrome (GAS)
General Adaptation Syndrome (GAS) is a theoretical framework proposed by Hans Selye in the 1930s to describe the body's physiological response to stress. It consists of three stages:
Alarm Stage: The first stage of GAS is the alarm reaction, during which the body perceives a stressor and activates the "fight or flight" response. Physiological changes such as increased heart rate, elevated blood pressure, and heightened alertness occur as the body prepares to confront or flee from the perceived threat.
Resistance Stage: If the stressor persists, the body enters the resistance stage, during which it attempts to adapt to and cope with the ongoing stressor. Physiological responses stabilize, and the body's resources are mobilized to maintain physiological functioning and cope with the stressor.
Exhaustion Stage: If the stressor continues for an extended period without relief, the body enters the exhaustion stage. During this stage, the body's resources become depleted, leading to increased susceptibility to illness, fatigue, and physical and mental breakdown.
GAS provides a framework for understanding the physiological responses to stress and highlights the importance of adaptive coping strategies in maintaining health and well-being.
