What is the general adaptation syndrome (GAS)? General adaptation syndrome, or gas, is a term used to describe the reactions to short term and long term body stress. Stress factors in humans include such physical stressors and emotional or mental, is about the influence of stress injury or illness. Is based on the body’s to response to a stressful environment distributed in three stages. What is the normal function of GAS? When the body systems, is maintain a stable and consistent balanced state. This concept is homeostasis What are the three stages of GAS?Describe them briefly. ALARM STAGE Reaction to stress is the first stage that allows us to recognize the existence of danger y also prepares us to deal with the threat, a.
k. a. the fight or flight response, and activation of the nervous system (SNS) and the adrenal glands. During this phase the main stress hormones cortisol, adrenaline, and noradrenaline, is released to provide instant energy.
But too much adrenaline results in a surge of blood pressure that can damage blood vessels of the heart and brain – a risk factor in heart attack and stroke.The excess production of the cortisol hormone can cause damage to cells and muscle tissues. Stress related disorders and disease from cortisol include cardiovascular conditions, stroke, gastric ulcers, and high blood sugar levels. At this stage everything is working as it should – but if have a stressful event, the body is immediately equipped with enough energy to handle it. RESISTANCE STAGE In second phase, the organism adapt to the stressor and If desired balance is achieved, the body returns to normal (HOMEOSTASIS).If the stressor will continue for long time, the appearance of the body’s looks normal but physiologically and the body’s internal functioning is not normal, Overuse by the body’s defense mechanism in this phase eventually leads to disease as peptic ulcer and ulcerative colitis, hypertension and cardiovascular disease inter alia.
This stage requires abnormally high levels of emotional and physical resources. If things do not change for the better then the next stage EXHAUSTION process is inevitable.EXHAUSTION STAGE This stage at the end, is when the body does not get the desired balance, ie when the stressor agent beyond us.
The organism ability to resist is depleted and this stage is characterized by the activation of the parasympathetic division of the automatic nervous systems. The body resources are not replenished and additional stressors occur the body suffers breakdowns that can lead to death. List and briefly explain at least five common sources of stress. PhysiologicalWe can mention the genetic causes, Example inherited, congenital causes, previous illnesses and injuries. Life Event Is the type of stress involves life events that affect us all. Example being fired from your job, getting divorce Daily Hassles The majority of causes of stress that we face on a day-to-day basis are not as extreme as life events.
Example Traffic jams, Time pressures. Physical environmental They are sources of stress, as an example in this category extreme temperatures, pollution, smog, noise, temperature extremes, etc.. PsychologicalMay be considered as the willingness of the person, their cognitive and emotional vulnerability.
Example the age-life crises such as adult, seniors, Low self-esteem, Unrealistic beliefs 1. (a) What is your own definition of stress? I could define stress as a disease that is triggered by situations as pressure, loosen a feeling of inability to meet the challenges of everyday life, and these responses, causing a series of reactions, physical, psychological, external or internal, good or bad, causes an identical body’s biological response and stereotyped.
