Animals And Humans Have A Biological Stress Response

Humans frequently turn on the stress response that was intended to assist our survival in reaction to the everyday challenges we face. Professor Michael Marmot conducted a study in England of 28,000 people’s health over a course of 40 years. Each person was a British

Stress Is the body’s way of responding to the hectic lives most of us live, whether good or bad. The body releases chemicals into the bloodstream, which creates a rush of energy and strength If an individual is feeling stressed. This energy can prove useful if an individual is in physical danger. Because it enables a person’s survival instinct kicks in; it is often described as ‘fight or flight.’ In addition, stress can also have a negative effect on the body, for example: suffering from stress and leaving it unchecked can contribute to health problems, such as high blood pressure, heart disease, obesity, and diabetes.

There are three different theories that are used when talking about how we react to stress through the physiological aspect or the psychological aspect. The first is part of the physiological aspect of stress called the Cannon Fight or Flight theory which was proposed in 1914. Fight or Flight response is a physiological stress response that evolved to help organisms to survive immediate danger. The theory states that when an organism, human being or animal, faces imminent danger (acute stressor) the body arouses quickly and is ready to act via two different systems. They are the sympathetic nervous system and the endocrine system. The sympathetic nervous system stimulates the adrenal medulla which is part of the endocrine system and is the region that produces the hormones such as adrenaline and noradrenaline. These hormones increase heart rate, blood flow, and glucose levels to prepare the body for an emergency. This response from the body suggests that the body knows how to protect itself and reach homeostasis. These two systems work together to either fight against the danger or flight away from the danger. Lord, King and Pfister in 1976 studied the Fight or Flight response in animals through a very unethical study. They administered chemicals on male hooded Wistar rats which inhibited the neurotransmitters from functioning normally. This made it very difficult for the rats to escape an electric shock. The results of the study suggest that the Flight or Fight response

In an acute stressor, the immune system is heightened. But is suppressed in a chronic stressor. In this situation the cortisol levels rise, and weaken the immune system. This weaken system can make the human body more susceptible to serious disease, infections

The National Geographic film, A Portrait of a Killer, examines the types of stress that living beings can endure, and how it can thus affect the rest of their bodies. Severe chronic stress can lead even lead to the destruction of brain cells. Dr. Robert Sapolsky is a neurobiologist of Stanford University who has been researching stress for over thirty years. In order to study stress and its implications upon nonhumans, he went to Africa to study baboons. This species has only three hours of stress caused by eating, and the rest of their daily routine is consumed by about nine hours of free time. Much like Western society, baboons socially stress out one another, as they have social hierarchies to regulate how them interact with one another.

The video “Stress Portrait of a Killer” was enlightening. The correlation between each individual’s placement in the hierarchy and their level of stress was not surprising. In fact, it made a great deal of sense. When one is on the lower end of the spectrum, it is a reasonable to anticipate higher levels of stress than when one is at the higher end. The latter, has more control over what is happening in their lives which in turn eliminates that stress. What I found most interesting, is that stress lowers the body’s immunity. I had no idea that the brain cuts non-essential systems like the immune system when stress is present. I found this fact fascinating and rather concerning. For as long as I can remember, I have been very susceptible to

Stress is natural and not necessarily a negative issue. Stress is a signal of change, whenever there is some significant change in one's life; it results to some level of stress in the body system. According to Smith (2008), Stress is a natural biological response to threat or luck of control in ones life. When the human brain perceives a threat, it sends messages to the adrenal glands, which in turn releases hormones that cause the body to be alert. One of these hormones is cortisol. Cortisol is a home that helps the body by reestablishing energy supplies, enhancing memory as well as the immune system. This hormonal activity in the body halts digestion and raises blood sugar level,

Viewed from an evolutionary standpoint, in early times stress caused the stimulation of the sympathetic nervous system resulting in an outpouring of the hormones epinephrine, norepinephrine, and glucocorticoids that were essential to the life-preserving fight or flight reactions of primitive man (Anthony 1988). However, the nature of stress for the individual today is different. It is only occasionally and unexpectedly that one is confronted with overwhelming, life-threatening stresses. Present stresses arise from everyday stresses of work, finances and school. The problem is that the body still continues to respond in the same fashion as primitive times. This makes the large release of hormones very harmful. They can cause an increase in blood pressure, damage muscle tissue, lead to infertility, inhibit growth, damage the hippocampus and suppress the immune system (Carlson 1994). It is therefore, important that individuals learn to control the stresses in their lives. The more detrimental coping behaviors will cause a larger change

The most critical stage of stress is when an individual cannot fight off their infections, depression and other health related problems is known as the chronic stress. When stress is not handled properly, over-time it can cause wear and tear to the body which affects a person’s body physical and mentally. For example, when a person undergoes surgery and they are experience high levels of stress their body make take longer to heal (ADA, 2013). This is a direct result of high blood glucose levels, which is product of stress hormones that are designed to deal with short-term

Stress can get bad enough to where it starts to affect your body system. Things like depression, heart attacks, diseases, rashes and a low immune system can all occur to people dealing with stress bad enough. The number of common signs and symptoms is outrageous and is depressing to see that there are so many people dealing with this and how it’s such a common thing in this world. On stress.org, they talk about the different body systems and how they’re affected. The nervous, musculoskeletal, respiratory, cardiovascular, endocrine, gastro and reproductive systems are all affected in some way and in many ways to say the least. If your stress ever gets so bad, I consider seeing a doctor or specialist seeing how dangerous this can get.

1.) Summary: Kelly McGonigal who is a health psychologist gives a thought-provoking lecture called “How to Make Stress Your Friend” at an official TED conference in June 2013. During the first part of the presentation, Ms. McGonigal confesses to the crowd that she been teaching about stress completely wrong, “Basically, I’ve turned stress into the enemy. But I have changed my mind about stress…” Ms. McGonigal emphasizes the point that people who view stress as not harmful (not their enemy), were less likely to die to people who view stress as their enemy; therefore, when people change their mind about stress, they can change their body response to stress to make them healthier. As the presentation gets further along, Kelly McGonigal states how oxytocin plays a huge role in controlling stress. This neuro-hormone, which is released during stress, motivates you to seek support, which is the reason why stress makes you social. At the same time, oxytocin acts

Chronic psychological stress is associated with the body losing its ability to regulate the inflammatory response. The inflammatory response is the body’s defense mechanism that protects it from infection and injury. Inflammation is partly regulated by the hormone cortisol and when cortisol is not allowed to serve its function the immune cells become insensitive to cortisol's regulatory effect. Prolonged stress alters the effectiveness of cortisol to regulate the inflammatory response by decreasing tissue sensitivity to the hormone. Unchecked inflammation is thought to encourage the development and progression of many diseases leading to a greater risk for depression, heart disease and infectious diseases.

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),

Everybody has at least one thing in common. Can you guess what it is? If you guessed, heartbreak, you’re right, but that’s not the answer I’m looking for. The correct answer is stress. Everyone has stress in his or her life at one point or another. It’s one of many inevitable parts of life. Whether it’s busting out a research paper for Psychology at the last minute, expecting your first child to be born, to making sure you’re up in time to catch the Saturday morning cartoons, it’s clearly evident that everyone goes through stress. The real question is, how is stress handled in our society? A person is defined by how they handle the stressors in their lives and how they overcome stressful moments. This paper will explore the aspects of

“Stress is a silent disease” (Doctor Hobel). Over the years, stress has played a major rule in a large majority of people’s lives throughout the United States. When thought about, it is said to be extremely surprising as to how many people really have stress in each individual’s life. People do not consider what the reasons are for the feelings and emotions they experience. There are all different types of stress, and stress can do a lot to a person. Each person also handles stress in a different way. Some can handle more than others, because every single person’s body works in a different way. Stress has also been told to cause people to act out of character (Dr. David Posen). They often do not act the way they usually would while under
