Stressors Case Study

839 Words4 Pages

1.1 Stress and Stressors The term stress was derived from physics by Hans Selye an endocrinologist who has been regarded as the father of stress research. He proposed that ‘stress is a non-specific strain on the body caused by irregularities in normal body functions’. Stress is anything that disturbs the “homeostasis” of the body (Schneiderman, 2005). It can also be defined as the inability of an animal to cope up with its surrounding environment (Dobson, 2000). It is characterised by physiological changes that occur in response to novel or threatening stimuli. These changes comprise a cascade of neuroendocrine events mediated by stress systems such as the hypothalamic–pituitary–adrenal axis (HPA) (Gregus et al, 2005). It can have a major …show more content…

Earlier, the stressors were classified as physical stress and psychological stress. Scientist and researchers have now proposed that the stressors can be divided into 2 more types, namely absolute and relative stressors. An absolute stressor is the one which is interpreted by everyone as a stressful event (like events of natural disaster or terrorism). The relative stressor is that, only those who are exposed to those type of stressors would interpret it to be stressful (like time pressure during work, pressure of taking up an exam).

Stress is not only an individual’s problem, but the problem of the community. Factors such as where we live, the state of the environment, genetics, income and education level, and relationships with friends and family all will have considerable impacts on health. A study by university of California showed stress due to work, family, finances, traumatic events (bereavement in the family), and neighbourhood issues lead to atrial fibrillation in more than 26,200 women in San Francisco. In India, apart from all these factors the changing culture and eventually the lifestyle of the community affects the individual. Thus, change in life style and the social factors are vital contributors to stress (Curtis et al,

My research paper will be focusing on the HPA (Hypothalamus-Pituitary Gland-Adrenal Gland) axis activation in response to stress with a focus on the harmful side effects of the end product of the HPA axis, cortisol hormone. I would also like to bring to attention how stress response can vary in different individuals with certain predisposition that can cause them to have severe physical responses to stress later in life, such as diabetes and cardiac health issues. My lens will be focusing on how college students, in particular, cope with stress while highlighting which coping methods they are using and evaluating how effective they are.

Hypothalamus-Pituitary Theory

1062 Words | 5 Pages

Stress and emotion have shown that their effects stem through the same bodily systems including the brain (limbic system), the autonomic nervous system, and hormones which today can be seen as the Hypothalamus-Pituitary-Adrenal system (HPA) (as mentioned in module 2). When in a, or following a stressful event, such as being fired, person K can begin to exhibit changes within his/her body. The activation of the Hypothalamus-Pituitary-Adrenal system during the stressful event activates the paraventricular nucleus of the hypothalamus, which sends electrochemical signals to the anterior pituitary, which produces adreno-corticotropic hormone (ACTH). This hormone stimulates the adrenal glands to have a final result of releasing the stress-related hormone cortisol into the bloodstream (as mentioned in our textbook, p.124). Cortisol activates glucose production needed for metabolically demanding action by suppressing his/her immune system, increasing heart rate and blood pressure thus distributing blood to appropriate muscle groups involved in the fight-or-flight behaviour (as mentioned in our textbook, 124).

Allostatic Load

1) Define the terms allostasis and allostatic load (2 marks, 1 sentence each). Allostasis is important for one’s survival, similar to the functions of homeostasis; it is defined as one’s capability to reach stability through a series of changes. Allostatic load is caused by chronic stress as one either encounters a maximum or minimum amount of activity that results the wearing and tearing of this system (McEwen, 1998). 2) Describe the 4 different types of allostatic load (Fig 3) and for each describe a study in either humans or animals (summarized in the McEwan article) that showed an adverse health outcome associated with that type of allostatic load (2-3 sentences each, 8 marks total). a) Type 1: The first type of allostatic load is frequent stress, caused from stressors and explained through studies on monkeys.

) There are many different kinds of support given to workers in order to help them deal with stress. Here we will be looking at types of stress support given to employees as well as their stressors, by giving examples of these derived from the case study. Types of support given can include psychological support, cognitive support, employee assistance programs and physical support (Lehrer et al, 1994). Types of stressors that employees face are work overload, work-life balance, emotional and physical labor, job ambiguity and job demands (Danna & Griffin, 1999). Under psychological support there are various mediation and relaxation techniques that are used in order to help support employees suffering from stress.

Hans Selye's Theory Of Stress

The awareness of stress was increased after World War II when it was noticed that many routine life events like examinations, growing up increases stress and leads to dysfunction (Lazarus, 1993). The word stress was used by Hans Selye for the first time to explain the effects of threats that disturbs homeostasis (Chrousos, 1992; Selye, 1978). Walter B. Cannon explained the role of adrenal glands and sympathetic nervous system in maintenance of body equilibrium after exposure to threat. Hans Selye’s observation -” common feeling of being sick” in patients with different diseases laid path for definition of stress. He defined stress as a set of non-specific responses collectively called as” General Adaptation Syndrome”.

Stress In College Students Essay

Stress involves interaction of the person and environment. To quote a definition: “Stress is an adaptive response to an external situation that results in physical, psychological and / or behavioural deviations for organizational participants” (Luthans, 1998). Stress has generally been viewed as a set of neurological and physiological reactions that serves an adaptive function (Franken, 1994). Traditionally, stress research has been oriented toward studies involving the body's reaction to stress and the cognitive processes that influence the perception of stress. However, social perspectives of the stress response have noted that different people experiencing similar life conditions are not necessarily affected in the same manner (Pearlin, 1982).

Acute stress or single exposure to stressor of minutes to hours will be not produce any ill effect as body have protective and adaptive effects managed by hormones and other physiological agents. However re-exposure has proven to be more enigmatic or difficult to reverse. Conrad et al (1999) stated that severe or prolonged exposure to stressors is harmful, brief or moderate stressors actually enhance neural function. Various behavioral studies focusing on the memory functions of the hippocampus have demonstrated that moderate stress enhances memory performance but severe stress causes adaptive plasticity and impairs memory. Prolonged stress produces interaction between local neurotransmitters and hormones leading to structural and functional damage causing suppression of neurogenesis.

INTRODUCTION Stress is a word derived from Latin word “Stingere” meaning to draw tight. (Mojoyinola, 2008) Stress is your body’s way of responding to any kind of demand or threat. When you feel threatened, your nervous system responds by releasing a flood of stress hormones, and including adrenaline and cortisol, which rouse the body for emergency action. Your heart pounds faster, muscles tighten, blood pressure rises, breath quickens, and your senses become sharper. These physical changes increase your strength and stamina, speed your reaction time, and enhance your focus.
