During the General Adaptation Syndrome, the body goes through three stages: alarm, resistance, and exhaustion. In the alarm stage, the body perceives a stressor and activates the fight-or-flight response, releasing stress hormones like adrenaline. In the resistance stage, the body tries to adapt to the stressor by maintaining elevated hormone levels and physiological responses. If the stressor persists, the body enters the exhaustion stage, where resources are depleted, leading to physical and psychological burnout.
A.) Resistance stage
The stressor first presents itself during the "alarm phase" of the general adaptation syndrome (GAS) response. In this initial phase, the body recognizes the stressor and activates the fight-or-flight response, leading to physiological changes such as increased heart rate and heightened alertness. This phase prepares the body to confront or escape the threat.
During the "exhaustion" stage of the general adaptation syndrome, disease is a probable outcome. This stage occurs after prolonged exposure to stress, when the body's resources are depleted and it can no longer effectively cope with stressors. As a result, the individual becomes more susceptible to illnesses and health issues due to weakened immune function and overall physical and mental fatigue.
Adrenaline is released during alarm phase of the general adaptation syndrome, when it is necessary to enlist the fight or flight response. This adaptation is so hard-wired in our bodies that simply watching a scary movie can elicit the response, cause the body to release Adrenaline, and bring about all the same physiological changes that are produced if a knife-wielding person attacked you. The same response can occur when you open your electric bill and see that you owe nearly $500, or when a person softly approaches so you didn't hear them coming and they surprise you.
During the resistance phase of the general adaptation syndrome, there is a high demand for glucose, especially by the nervous system. The hormones GH-RH and CRH increase the levels of GH and ACTH, respectively. Growth hormone mobilizes fat reserves and promotes the catabolism of protein; ACTH increases cortisol, which stimulates both the conversion of glycogen to glucose and the catabolism of fat and protein.
The body's attempt to reestablish internal equilibrium occurs in the resistance stage of Selye's general adaptation syndrome. During this stage, the body adapts to the stressor and attempts to return to a state of homeostasis while continuing to cope with the stress. If the stress persists, the body remains in this stage, which can eventually lead to exhaustion if the stressor is not resolved.
The General Adaptation Syndrome (GAS) describes the body's physiological response to stress and consists of three stages: alarm, resistance, and exhaustion. Its primary function is to prepare the body to handle stressors effectively, promoting survival through increased alertness, energy mobilization, and resilience. During the alarm stage, the body reacts to a stressor, while the resistance stage involves adaptation and coping mechanisms. If stress persists beyond the body's capacity to adapt, the exhaustion stage can lead to decreased performance and health issues.
General adaptation syndrome, also called GAS, is what is used to describe the body's short-term and long-term reactions to stress. The three stages are: the alarm reaction, the stage of resistance, and the stage of exhaustion.
The stage resistance in the General Adaptation Syndrome (GAS) refers to the second phase of the body's response to stress, following the alarm reaction. During this stage, the body attempts to adapt to the ongoing stressful situation, utilizing resources to cope with the stressor. Physiological responses, such as increased hormone production, help maintain homeostasis, but if the stress persists for too long, it can lead to exhaustion and a decline in health. Ultimately, prolonged resistance can compromise the immune system and increase vulnerability to illness.
