Effects Of Stress On Homeostasis By Hans Selye

Stress is very well known for just what it means: STRESS. Its effect on human beings from a local and a global standpoint is far greater than any of us imagine. Stress can overtake one’s body physically, mentally, emotionally, as well as behavioral aspects. This is not something to take lightly. This is actually very serious. If you notice, it’s not just older people that die this day and time with heart attacks, suicide, and things of this nature. People of all ages. Older people, younger people, and even really young people. Children, yes, I said children. Don’t automatically think that stress only affects older people that have lived a longer

Another interesting part of this book, talks about the decreased immune response during times of stress. Hans Selye, one of the godfathers of stress physiology, discovered the first evidence of stress-induced immunosuppression back in the 1930s. Selye learned that the same glucocorticoids that are responsible for sympathetic response, was also a large contributor in immune system suppression. Glucocorticoids stop the formation of lymphocytes as well as inhibit the release of interleukins and interferons which make already circulating lymphocytes less responsive to infections. Sapolsky hypothesized why evolution would create this process from happening. He wanted to know why

The term ‘stress’ was generally thought to have been a concept created by Robert Hooke in the 17th century. He worked on the design of physical structures, such as bridges; his concept of stress came from how much pressure a structure could withstand. However, Lazarus (1993) pointed out that the term ‘stress’ has been used as far back as the 14th century, when it meant hardship or adversity. Back then it referred to the external stressor, such as the death of a spouse or financial worry; in the 20th century, there are many different schools of thought on this area. Hans Selye (1956), brought together the work of Cannon and Bernard and devised a comprehensive system of physiological stress; which he termed the ‘General Adaptation Syndrome’,

This assignment will explore the concept of stress by firstly distinguishing between the definitions set out by Selye 919560 and Cox (1976). Following this assignment will critically evaluate the General Adaption Syndrome, SRRS and Daily Hassles explanations of stress and finally, conclude with a discussion on individual differences based on Friedman and Rosenman’s research.

Why Zebras Don’t Get Ulcers is a book about the physiology of stress. It gets into great detail about what exactly is going on inside the body during periods of high stress, and also what short and long term affects are caused by that stress. The first chapter give a brief description of each chapter in the rest of the book. Each subsequent chapter explains different stressors, levels of stress, and hormonal responses to stress. Many of the chapters also include research and discoveries on how stress affects the human body, many of which are somewhat recent discoveries, only occurring in the last one hundred years or so. Robert Sapolsky is able to explain to his readers much about the physiology of stress and how endocrinology plays the most

The biological purpose of the stress response is to help the body to survive either some sort of attack or a serious illness like a stroke or heart attack. During the stress response glucocorticoids divert the bodies energy to the areas necessary for survival like the muscles and the brain and it shuts down the areas that are not necessary for survival like the digestive and immune systems (Sopolsky, 2009). Chronic Stress in this context, is to experience this physical effect on regular or long term basis. This has become a public health issue for humans because we experience this chronic biological response on a too frequent a basis for psychological reasons (Stress, 2008).

In evaluating the GAS Theory, it is helpful to note that it was the first systematic attempt to describe the body’s response to stress. However, all Selye’s early work was carried out on rats, using physical stressors. There are physiological differences between rats and humans making it difficult to generalise his research findings to people.

Stress was defined by Selye as "the nonspecific response of the body to any demand" (Christopher, 1996), the

Stress has been defined by Selye as a non-specific organic response to situations that are stressful to the organism. Its presence in a moderated form signifies a normal adaptation to day-to-day demands. When it is excessive, it is a manifestation of psychological distress with physical and emotional reactions, and the symptoms vary depending on the phase in which it is found. In her

Although a range of previous findings on stress physiology suggest that stress may have ameliorating or detrimental capacities, the possible connections between stress and diseases remain hotly debated despite its wide acceptability (Esch, 2002). Based on this premise, researchers have in recent years intensified investigation on the role of stress in various diseases such as neurological, mental, epidemiological, and cardiac diseases to mention but a few. Particularly, researchers in the field of stress research have been more concerned about the underlying mechanisms and pathophysiological pathways by which the onset of diseases are potentially influenced by stress, this domain however continues to be widely studied. For instance, it is believed that stress represents a major complicating factor in neurological illness and

Long-term alterations in the secretion include a glutocorticoid hormones cortisol via the hypothalamus pituitary adrenal access personal play crucial role in mediating the link between chronic stress exposure and ability to variety of diseases. (Stalder et al. 2012) Some of the biological consequences of such arousal were first identified by Selye (1956) as the General Adaptation Syndrome. Selye noted t h a t a principal characteristic of this response is an elevation in cortisol level. As a result of this early work and of more recent laboratory-based research, cortisol is now often regarded a s a "stress hormone" and as an objective marker of stress (Baum et al., 1982). (Pollard 1995)Registering for stressors cognitive affective states

Stress is an emotional state that is difficult to define because everyone experiences stress in different ways. Pathologically speaking, stress is the brain’s response to certain demands for change and can be positive or negative depending on the individual. This state of mind is induced by physical and emotional stimuli; this in turn generates a response that affects many aspects of a person’s wellbeing. Psychological, behavioral and biological stressors all play a role in an individual’s mood, sense of well-being, behavior and health (Schneiderman, Ironson, & Siegel, Stress and health: psychological, behavioral, and biological determinants, 2005). These factors can threaten our internal homeostasis which

The documentary “Stress the Portrait of a killer” was quite interesting. This documentary teaches you about stress and the effects it has on both animals and humans. Stress plays a huge factor on our daily lives. There are two hormones that are the workhorses of the whole stress response. These hormones are the adrenaline and glucocorticoids and they tend to come out along with each other. However, there happens to be positive and negative stress. For instance, roller coaster rides are considered to be positive stress. In addition, fat can be considered as negative stress because fat that is brought on by stress is known as dangerous fat. Ultimately, there are different levels and outcomes of stress.

Psychological stress is pressure placed on a person to adapt, cope, or adjust to a situation (Rathus, 2016, p.284). The result of prolonged stress can affect a person’s mood, pleasure experience, and have harmful effects on physical health (Rathus, 2016, p.284). Society in the twenty first century places high demands on people. Technology makes it very difficult to separate work life, school life, and home life. Today, society places a high value on a busy lifestyle for individuals. For example, many places of business are open twenty-four hours a day. In addition to societal pressures, attending a university adds to the stressors a person may experience. Going to school not only includes classroom time but it also includes homework,

Psychological and physical well-being and the overall quality of life are under a constant threat of stress and thus, psychological and medical sciences have long been concerned with studying stress response. Cox (1979) claimed that because of the poor understanding and defining it, the concept of stress tends to be rather elusive. The term, “stress”, commonly describes any physchological or physical alteration that deranges the organism’s homeostasis (or balance). This essay reviews some of the biological factors involved in stress and it has been organized in the following way. The paper begins by briefly introducing the concept of stress. It will then go on to discus and describe the automatic response (fight or flight reaction),
