How does stress affect the body?

If the reactions that compose the stress response are chronic or if they frequently exceed normal ranges, they can lead to cumulative wear and tear on the body, in much the same way that running your air conditioner on full blast all summer will eventually cause wear and tear on it. For example, the high blood pressure that a person under considerable job strain experiences might eventually take a toll on his heart and set the stage for a heart attack or heart failure. Also, someone exposed to high levels of the stress hormone cortisol might become vulnerable to infection or disease because of weakened immune system functioning (McEwen, 1998).

What is the cardiovascular system?

The cardiovascular system is composed of the heart and blood circulation system. For many years, disorders that involve the cardiovascular system—known as cardiovascular disorders —have been a major focal point in the study of psychophysiological disorders because of the cardiovascular system’s centrality in the stress response (Everly & Lating, 2002). Heart disease is one such condition. Each year, heart disease causes approximately one in three deaths in the United States, and it is the leading cause of death in the developed world (Centers for Disease Control and Prevention [CDC], 2011; Shapiro, 2005).

What are the risk factors for cardiovascular disease?

What is the silent killer of heart disease?

A major risk factor for heart disease is hypertension, which is high blood pressure. Hypertension forces a person’s heart to pump harder, thus putting more physical strain on the heart. If left unchecked, hypertension can lead to a heart attack, stroke, or heart failure; it can also lead to kidney failure and blindness. Hypertension is a serious cardiovascular disorder, and it is sometimes called the silent killer because it has no symptoms—one who has high blood pressure may not even be aware of it (AHA, 2012b).

Why are physiological reactions beneficial?

These reactions are beneficial at times because they prepare us to deal with potentially dangerous or threatening situations (for example, recall our old friend, the fearsome bear on the trail). However, health is affected when physiological reactions are sustained, as can happen in response to ongoing stress.

How does stress affect illness?

The susceptibility to stress varies from person to person. An event that causes an illness in a person may not cause illness in other person. Events must interact with a wide variety of background factors to manifest as an illness. Among the factors that influenced the susceptibility to stress are genetic vulnerability, coping style, type of personality and social support. When we are confronted with a problem, we assess the seriousness of the problem and determine whether or not we have the resources necessary to cope with problem. If we believe that the problem is serious and do not have the resources necessary to cope with the problem, we will perceive ourselves as being under stress (2). It is our way of reacting to the situations that makes a difference in our susceptibility to illness and our overall well-being.

How do life events affect neurotic illness?

(52) found that patients with obsessive-compulsive neuroses who have abnormal personality traits (obsessional, anxious and self-conscious) experienced significantly fewer life events than those without such traits. Zheng and Young (53) in comparing live event stress between neurotic patients and normal control found that neurotic patients had significantly higher level of stress and experienced more life event changes than the control group. Rajendran et al. (54) who compared the neurotic executives with healthy executives as a control group, found significant differences between normal and neurotic groups in terms of the frequency of the life events as well as the stress they experienced due to those life events.

How does stress affect breast cancer?

The relationship between breast cancer and stress has received particular attention. Some studies have indicated an increased incidence of early death, including cancer death among people who have experienced the recent loss of a spouse or loved one. A few studies of women with breast cancer have shown significantly high rate of disease among those women who experienced traumatic life events and loses within several years before their diagnosis. However, most cancers have been developing for many years and are diagnosed only after they have been growing in the body for a long time. Thus, this fact argues against an association between the death of a loved one and the triggering of cancer. There is no scientific evidence of a direct cause-and-effect relationship between these immune systems changes and the development of cancer. It has not been shown that stress-induced changes in the immune system directly cause cancer. However, more research is needed to find if there is a relationship between psychological stress and the transformation of normal cells into cancerous cells. One area that is currently being studied is whether psychological interventions can reduce stress in the cancer patients, improve immune function and possibly even prolonged the survival.
