Outline and evaluate research into the relationship between the immune system and stress related illness (12 marks)
Cohen et al (1993) investigated the role of general life stress on vulnerability to the common cold virus. He found that the chance of developing a cold, i.e. failing to fight off the infection, was significantly correlated with stress index scores. Cohen et al. concluded that life stress and negative emotions reduce the effectiveness of our immune system, leaving participants less able to resist viral infection.
Support for research into the relationship between the immune system and stress related illness came from studies such as Evans and

The Music Effect
Can music really effect mood, behavior, and the way we think? The answer is yes, with a big fat Y! There are certain types or genres of music that affect not just your physicality but your mind as well. There is evidence that it greatly impacts the way we perceive. A mere snippet of a song can trigger memories as vivid as anything. A tune can induce emotions ranging from overwhelming joy to deep sorrow and can drive listeners into a state of frenzy. Music can also kick a long haunting addiction, boost your immune system, even repair brain damage. In this paper we’ll explore how the effects of music on a person can be just as dangerous or therapeutic as some of

Irritant Contact Dermatitis. This skin rash does not require exposure to an allergen but can develop when you come in contact with substances such as detergents, oils, skin cleansers, and solvents.
Psoriasis is a chronic skin disease characterized by skin scaling and inflammation. This disease affects about 5.5 million people in the United States. It occurs in all age groups and affects both men and women. When psoriasis develops, patches of skin redden and become covered with scales. The skin then cracks and may cause severe irritation in places like the face, scalp,
elbows, knees, and lower back.
It is believed that psoriasis is a disorder of the immune system in which there are not enough white blood cells to help protect the body against infection and diseases of this type.

With all the concerns about cold and flu viruses, combating germs can sometimes feel like a full-time job. Surprisingly, there may be something you can do in the bedroom to keep your immune system strong, says Dr. Ebanks, who points to a study by researchers at Wilkes University in Pennsylvania. “Individuals who have sex once or twice a week show 30 percent higher levels of an antibody called immunoglobulin A, which is known to boost the immune system,” he says. So, make this your new cold-and-flu season mantra: Wash your hands and make a bedroom

What are scientist doing to solve the problem of psoriasis?
Psoriasis is an immune-mediated disease , which is abnormal activity of the body's immune system, in which the T-cells behave abnormally this then affects the skin.(1) Psoriasis happens when the skin replacement process speeds up, taking just a few days to replace skin cells that usually take 21-28 days, the skin cells build up , instead of shedding the extra skin cells they form raised areas on the skin, which can be flaky, scaly or red. (2)There is not a fully understood cause of psoriasis, but it is believed to have a genetic component, and is believed to be triggered by stress and/or injury to the skin.(3)It’s also believed

antibodies). All the water, salts and proteins are ultimately derived from the food we eat. Water and salts are regulated by the renal system. Albumin is produced by the liver and antibodies are a product of the immune system. There is also a balance of proteins and water within the vasculature (intravascular space) and without (extravascular space). There is always an influx or efflux balance between the tissues and the vasculature depending on the osmotic and mechanical pressure. This is all in one giant balance or homeostasis most of the time.

stumped. Many are calling multiple sclerosis an autoimmune disease, which means your immune system is fighting off the healthy cells mistakenly. There are others who disagree that are calling the disease immune-mediated. This is because a particular antigen that your immune cells are attacking is still unknown. Multiple sclerosis attacks the central nervous system (CNS) that consists of the brain, spinal cord, and the optic nerves. Your body’s immune system attacks the protective coating around nerve cells called myelin. The damage that is done to the nerve cells affects the messages that are sent between the brain and your body and leads to multiple sclerosis, which causes problems for

Addison’s Disease is usually caused by a problem with the adrenal glands themselves. A lot of the time the body’s self-defense mechanism, the immune system, mistakenly attacks the adrenal glands. When these attacks happen it destroys the outer layer of the glands. Long-lasting infections such as HIV or tuberculosis can also harm the glands. Addison’s disease can also be brought on by body spreading cancer cells.
All treatment associated for Addison’s Disease is in the form of hormone replacement therapy. One drug you could use would be oral corticosteroids. A doctor would prescribe these pills to you to help replace aldosterone. Other medicines such as hydrocortisone, prednisone, or cortisone acetate may be used to replace cortisol. Another form of treatment would be corticosteroid injections. These injections are normally used if a patient experiences vomiting when taking the oral corticosteroids and can’t keep the pills down.

Stress and the Immune System
The immune system is actually responsible for providing defense for our body against any type of disease. The body is continuously involved in search for invading microbes and destroys them accordingly to protect the individual. It has been suggested that it is not the occasional stress but incidence of chronic stress that weakens the body’s defensive mechanism and immunity. This weakening of the defensive system increased the chance of body being attacked by different chronic diseases such as flu or

In 2000, George Bierson’s "Marijuana, the Deceptive Drug", was published by the Massachusetts News. Bierson concludes that marijuana is harmful in many ways, including brain damage, damage to the reproductive system, and weakening of the immune system. He also attempts to convince the reader that marijuana is a "gateway drug" that leads the users to venture into much harder drugs. I believe that research to support anything can be found if one is looking hard enough, but that the fallacy of Bierson’s conclusion is due to his research seeking facts to support an already-assumed conclusion. Based on my research and my own personal experience, I have found that several of his

The spleen is a lymphoid organ, part of the Lymphatic System. It is the size of a closed fist and lies just below the diaphragm, tucked against the top of the stomach on the left side of the abdominal cavity (Marieb & Hoehn, 2013). It is the first organ in the embryo to produce red blood cells (Turbyville, 2012) but, later in life, it functions as a filter to remove old or damaged red blood cells from circulation. It also stores about 250mL of blood which can be released into the blood circulation in emergencies (Marieb & Hoehn, 2013). As a part of the immune system, it stores and produces lymphocytes which produce essential antibodies and release

Vitamins are a valuable component to a healthy diet, because our bodies cannot make them or our bodies cannot produce enough of them to provide adequate nutrition to our cells. Vitamins are essential for everyday body functions such as cell growth, blood cell production, hormone production, and metabolism. Vitamins can also affect body systems such as the reproductive system, circulatory system, and the immune system.
Fat soluble vitamins consist of vitamin A, D, E, and K. These vitamins only dissolve in fat not in water and are stored in fatty tissues as well as the liver. These vitamins can be stored for long periods of time and people consuming a well-balanced diet

Human immunodeficiency virus, otherwise known as HIV, is a serious disease that affects the bodies’ immune system. HIV affects the immune cells, specifically called the CD4 cells or T cells. As time passes, these cells are destroyed and soon the body begins to lose its ability to fight off infections and disease. HIV is the virus that could lead to acquired immunodeficiency syndrome, or AIDS. Unfortunately, there is no cure for HIV, meaning once infected, you will remain infected for the rest of your life.

Blood is not considered the “fluid of life” without valid reason. This essential liquid is circulated throughout the human body within veins, capillaries and arteries to our heart, where it is cleaned from contaminants and waste products, then replenished with nutrients and oxygen needed to maintain life. That is the way the human body system nourishes its cells. Blood provides the necessary nutrients to our cells to keep them alive.
