How Stress Influences Disease Study

Kelly McGonigal discusses the importance of viewing stress as positive, as opposed to negative, by detailing three specific studies and findings about stress. In the first study, it was discovered that people with a significant amount of stress had a higher mortality rate; however, this was only statistically significant if the subject viewed stress as harmful. If the overly-stressed subject didn’t view stress as harmful, they were actually at the lowest risk of dying, even compared to those with a minimal amount. Therefore, it is important to change a person’s perspective of stress. In particular, McGonigal emphasizes that stress is important for a person’s body: it energizes and prepares them to meet whatever challenge they are facing. Furthermore, it helps the blood vessels remain relaxed, thereby allowing the heart to remain healthy.

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

Getting sick is another negative factor of being overly stressed. Chronic stress compromises your immune system and stress hormones affect the body’s ability to fight off illness due to the fact that thymus’s ability to stimulate and coordinate the white blood cell activity.

Most studies of the relationship between stress and the immune system have focussed on acute(i.e. short lived) stressors and have found a decrease in immune cell function.

Initial response to stress activates immune systems; prolonged stress weakens the immune system making you more susceptible to getting sick.

People are increasingly facing more stress since the Human-Being society became developed and complicated, by ignoring the physical influence to our body, Human’s health suffered considerably from stress. Many people was suggested to solve the stress problem by using psychological approaches, however, the research in recent decades has identified a significant awareness gap between the benefits of physical activities and stress relief. The following paper is aiming at exploring how stress affects physical health and how to relieve stress physically.

Society defines stress as anything which forces us to change. Through technical terms stress is defined as “a negative emotional state occurring in response to events that are perceived as taking or exceeding a person’s resources or ability to cope.” To explaining stress researchers came up with the “Cognitive appraisal model”, this system works to tell us whether we believe we have enough resources to deal with the situation without becoming stressed. For instance as a now college student those who have had previous experience taking finales in high school can have less stress than those who have not taken it. This is because they have previous experience with taking the tests and learning how to study while those who have never taken one can become extremely stressed over the unknown of the test. Stress is one of the sub branches that is attached to the world of health psychology. Health psychology is a quickly growing branch that deals with the way the mind and body work together. Psychologists that work in the health field came up with the biopsychosocial model. This model explains the complex interaction with biological, psychological, and social factors.

The aim of this review is to discuss the mechanisms by which the nervous and immune systems interact to affect each other during periods of stress (psychological and physiological), the specific effects of cortisol-mediated stress on the immune system based on the magnitude and duration of the stressor, and the models proposed to explain these effects.

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

This article was written by a team of people so there is a lot of information. They talk about what stress is and what it can cause. Also about what hormones are released while stress is occurring. They give good examples of when we feel stressed, for example, they mention when you are on a morning walk and you hear a very loud dog barking at you. Your body releases a bunch of hormones through your body to prepare you to “fight or flight”. They explain what these hormones do to your body and how we react. They also give a list of symptoms that stress can cause. The Mayo Clinic produces a lot of medical information so I believe that this is a credited resource and provides accurate information. This article seems to be for people who are looking

Indo Asian News Service reported an article on the effects of stress about our immune system. In this article it mentions a study done to show that controlled stress improves the immune system. “Short-term stress, the fight-or-flight response, a mobilisation of bodily resources lasting minutes or hours in response to immediate threats -- stimulates immune activity” (“Stress” 2). This statement was given by a researcher and professor, Firdaus Dhabhar. He was explaining his purpose for his research and the process he would go through.

Even lowering resistance to certain type of viruses. Stress does not only cause detoriation to heart but to your gums as well making you less immune from common colds to cancer. People who are stressed are very much more likely to pick up habits like smoking, over eating, and are even less likely to exercise.

They have also found that there are strong links between prolonged stress and disorders, mentally and physically. Kiecolt-Glaser et al 1995 also carried out research into the relationship between Stress and the Immune System. Kiecolt-Glaser et al 1995 = == ==

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,

      Stress can cause many things that affect a healthy body.  Stress causes quick yet shallow breathing in which case, the body's cells are being deprived of oxygen.  Stress will increase cholesterol levels and can also cause indigestion, heartburn, a decreased sex drive, and also arteriosclerosis (the hardening of the arteries).  While these symptoms may seem minimal, stress can decrease the activity of white blood cells.  Since the white blood cells fight off sicknesses and diseases, the immune system is affected by stress and can make the body more susceptible to colds, viruses, flues, and diseases (Morrison 2).
