Certain types of stress can be good for you such as the stress caused by a romantic encounter or the anticipation of a reward (Hadley and Staudacher 1996). However, not all stress is good and prolonged stress can make us very ill. It was by chance that Hungarian-born Hans Selye (1907-1982) stumbled upon the stress syndrome; this is what Selye came to call the process under which the body confronts "stress". Selye explained, the body passes through three universal stages of coping. First there is an "alarm reaction," in which the body prepares itself for "fight or flight."
Outline and evaluate research into the relationship between the immune system and stress-relates illnesses (12 marks) The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. White blood cells, also called leukocytes, are part of this defence system. There are two basic types of these germ-fighting cells; phagocytes, which chew up invading germs and lymphocytes, which allow the body to remember and recognize previous invaders. Long term suppression of the immune system leaves the body vulnerable to disease and infection. For this reason it is said that stress weakens the immune system.
Hypostress is when a person is stuck in a monotonous life and thus finds themselves bored and unmotivated. Eustress is that stress which everyone will have had at some point and is considered healthy and necessary. It is what motivates and drives people to meet their deadlines, goals and challenges.

On the other hand, negative stress which we mostly undergo, come in crisis situations which we cannot cope with. All negative stress are considered feeling sad, depressed, angry or fear. For example, stress comes when you are fearful and have no control over your reaction. There are many ways to help reduce stress.
3) Biofeedback is also a way of measuring stress. It deals with the physiological symptoms of stress such as raised blood pressure and increased muscle tension. We are unable to control then consciously because they are overseen by our autonomic nervous system (ANS). If these systems were controlled consciously, they would constantly be playing on our minds. Biofeedback is a method by which an individual learns to apply voluntary control over involuntary behaviours by being made aware of what is happening in the ANS.
The inflammatory response is the body’s natural response that occurs immediately after the tissue is damaged. The responses main functions are to defend the body against harmful substances, dispose of dead or dying tissue and to sponsor the renewal of normal tissue. The inflammatory reaction is normally put into 5 different characteristics, each of which is due to a physiological response to tissue injury. Pain (pressure on the nerves in and around the affected site), Swelling (blood that exits the tissue and collects in the interstitial spine, Redness (warmth when blood vessels dilute), Heat and Loss of function (bear weight due to pain and swelling). Acute response This often occurs immediately after an injury but can take up to 72 hours for enough tissue fluid to accumulate in order to cause symptoms of pain and stiffness (from swollen muscles).
Physical symptoms include increased heart rate, sweaty palms, muscle tension, sleep and sudden weight loss or gain. Psychological symptoms include anxious thoughts, low self esteem and confidence, fearfulness, difficulty making decisions, negativity, withdrawal, frustration
More nutrients are used and body temperature rises. To perform as efficiently as possible the cardiovascular system must regulate these changes and meet the body’s increasing demands. The respiratory system has different affects to exercising. When you exercise, your body has an increased need for oxygen. The muscles working in your body need oxygen in order to function, as the heart responses by pumping out more oxygenated blood to your muscles, the respiratory system also makes adjustments to help meet the demands of the body during exercise.
The second main reason that people should stop using steroids is, because it can kill them. There are many ways steroids can kill you. Steroids can cause liver failure, high blood pressure, cancer, strokes caused by blood clots and most of all major heart attacks. The reason people have heart attacks from steroid use is because it makes your blood to thick to pump through your heart, causing your heart to work much harder than normal, and then causing the person to have a heart attack. The third main reason that people should not use steroids is because it causes many other health problems in their life.
