Stress is defined as an organism's total response to environmental demands or pressures. When stress was first studied in the 1950s, the term was used to denote both the causes and the experienced effects of these pressures. More recently, however, the word stressor has been used for the stimulus that provokes a stress response. One recurrent disagreement among researchers concerns the definition of stress in humans. Is it primarily an external response that can be measured by changes in glandular secretions, skin reactions, and other physical functions, or is it an internal interpretation of, or reaction to, a stressor; or is it both?


Stress in humans results from interactions between persons and their environment that are perceived as straining or exceeding their adaptive capacities and threatening their well-being. The element of perception indicates that human stress responses reflect differences in personality, as well as differences in physical strength or general health.
Risk factors for stress-related illnesses are a mix of personal, interpersonal, and social variables. These factors include lack or loss of control over one's physical environment, and lack or loss of social support networks. People who are dependent on others (e.g., children or the elderly) or who are socially disadvantaged (because of race, gender, educational level, or similar factors) are at greater risk of developing stress-related illnesses. Other risk factors include feelings of helplessness, hopelessness, extreme fear or anger, and cynicism or distrust of others.

Causes and symptoms


The causes of stress can include any event or occurrence that a person considers a threat to his or her coping strategies or resources. Researchers generally agree that a certain degree of stress is a normal part of a living organism's response to the inevitable changes in its physical or social environment, and that positive, as well as negative, events can generate stress as well as negative occurrences. Stress-related disease, however, results from excessive and prolonged demands on an organism's coping resources. It is now believed that 80-90% of all disease is stress-related.
Recent research indicates that some vulnerability to stress is genetic. Scientists at the University of Wisconsin and King's College London discovered that people who inherited a short, or stress-sensitive, version of the serotonin transporter gene were almost three times as likely to experience depression following a stressful event as people with the long version of the gene. Further research is likely to identify other genes that affect susceptibility to stress.
One cause of stress that has affected large sectors of the general population around the world since 2001 is terrorism. The events of September 11, 2001, the sniper shootings in Virginia and Maryland and the Bali nightclub bombing in 2002, the suicide bombings in the Middle East in 2003, have all been shown to cause short-term symptoms of stress in people who read about them or watch television news reports as well as those who witnessed the actual events. Stress related to terrorist attacks also appears to affect people in countries far from the location of the attack as well as those in the immediate vicinity. It is too soon to tell how stress related to episodes of terrorism will affect human health over long periods of time, but researchers are already beginning to investigate this question. In 2004 the Centers for Disease Control and Prevention (CDC) released a report on the aftereffects of the World Trade Center attacks on rescue and recovery workers and volunteers. The researchers found that over half the 11,700 people who were interviewed met threshold criteria for a mental health evaluation. A longer-term evaluation of these workers is underway.
A new condition that has been identified since 9/11 is childhood traumatic grief, or CTG. CTG refers to an intense stress reaction that may develop in children following the loss of a parent, sibling, or other loved one during a traumatic event. As defined by the National Child Traumatic Stress Network (NCTSN), "Children with childhood traumatic grief experience the cause of [the loved one's] death as horrifying or terrifying, whether the death was sudden and unexpected (for example, due to homicide, suicide, motor vehicle accident, drug overdose, natural disaster, war, terrorism, and so on) or due to natural causes (cancer, heart attack, and so forth). Even if the manner of death does not appear to others to be sudden, shocking, or frightening, children who perceive the death in this way may develop childhood traumatic grief. In this condition, even happy thoughts and memories of the deceased person remind children of the traumatic way in which the deceased died." More information on the identification and treatment of childhood traumatic grief can be obtained from the NCTSN web site, 〈〉.


The symptoms of stress can be either physical or psychological. Stress-related physical illnesses, such as irritable bowel syndrome, heart attacks, arthritis, and chronic headaches, result from long-term overstimulation of a part of the nervous system that regulates the heart rate, blood pressure, and digestive system. Stress-related emotional illness results from inadequate or inappropriate responses to major changes in one's life situation, such as marriage, completing one's education, becoming a parent, losing a job, or retirement. Psychiatrists sometimes use the term adjustment disorder to describe this type of illness. In the workplace, stress-related illness often takes the form of burnout—a loss of interest in or ability to perform one's job due to long-term high stress levels. For example, palliative care nurses are at high risk of burnout due to their inability to prevent their patients from dying or even to relieve their physical suffering in some circumstances.


When the doctor suspects that a patient's illness is connected to stress, he or she will take a careful history that includes stressors in the patient's life (family or employment problems, other illnesses, etc.). Many physicians will evaluate the patient's personality as well, in order to assess his or her coping resources and emotional response patterns. There are a number of personality inventories and psychological tests that doctors can use to help diagnose the amount of stress that the patient experiences and the coping strategies that he or she uses to deal with them. A variation on this theme is to identify what the patient perceives as threatening as well as stressful. Stress-related illness can be diagnosed by primary care doctors, as well as by those who specialize in psychiatry. The doctor will need to distinguish between adjustment disorders and anxiety or mood disorders, and between psychiatric disorders and physical illnesses (e.g., thyroid activity) that have psychological side effects.


Recent advances in the understanding of the many complex connections between the human mind and body have produced a variety of mainstream approaches to stress-related illness. Present treatment regimens may include one or more of the following:
  • Medications. These may include drugs to control blood pressure or other physical symptoms of stress, as well as drugs that affect the patient's mood (tranquilizers or antidepressants).
  • Stress management programs. These may be either individual or group treatments, and usually involve analysis of the stressors in the patient's life. They often focus on job or workplace-related stress.
  • Behavioral approaches. These strategies include relaxation techniques, breathing exercises, and physical exercise programs including walking.
  • Massage. Therapeutic massage relieves stress by relaxing the large groups of muscles in the back, neck, arms, and legs.
  • Cognitive therapy. These approaches teach patients to reframe or mentally reinterpret the stressors in their lives in order to modify the body's physical reactions.
  • Meditation and associated spiritual or religious practices. Recent studies have found positive correlations between these practices and stress hardiness.

Alternative treatment

Treatment of stress is one area in which the boundaries between traditional and alternative therapies have changed in recent years, in part because some forms of physical exercise (yoga, tai chi, aikido) that were once associated with the counterculture have become widely accepted as useful parts of mainstream stress reduction programs. Other alternative therapies for stress that are occasionally recommended by mainstream medicine include aromatherapy, dance therapy, biofeedback, nutrition-based treatments (including dietary guidelines and nutritional supplements), acupuncture, homeopathy, and herbal medicine.


The prognosis for recovery from a stress-related illness is related to a wide variety of factors in a person's life, many of which are genetically determined (race, sex, illnesses that run in families) or beyond the individual's control (economic trends, cultural stereotypes and prejudices). It is possible, however, for humans to learn new responses to stress and, thus, change their experiences of it. A person's ability to remain healthy in stressful situations is sometimes referred to as stress hardiness. Stress-hardy people have a cluster of personality traits that strengthen their ability to cope. These traits include believing in the importance of what they are doing; believing that they have some power to influence their situation; and viewing life's changes as positive opportunities rather than as threats.


Complete prevention of stress is neither possible nor desirable, because stress is an important stimulus of human growth and creativity, as well as an inevitable part of life. In addition, specific strategies for stress prevention vary widely from person to person, depending on the nature and number of the stressors in an individual's life, and the amount of control he or she has over these factors. In general, however, a combination of attitudinal and behavioral changes works well for most patients. The best form of prevention appears to be parental modeling of healthy attitudes and behaviors within the family.

1. forcibly exerted influence; pressure.
2. in dentistry, the pressure of the upper teeth against the lower.
3. a state of physiological or psychological strain caused by adverse stimuli, physical, mental, or emotional, internal or external, that tend to disturb the functioning of an organism and which the organism naturally desires to avoid. stress reactions are elicited but should these reactions be inappropriate or inadequate, they may lead to disease states. The term is also used to refer to the stimuli that elicit such a state or stress reactions. Just as a bridge is structurally capable of adjusting to certain physical stresses, the human body and mind are normally able to adapt to the stresses of new situations. However, this ability has definite limits beyond which continued stress may cause a breakdown, although this limit varies from person to person.

Physical Stress. There are many kinds of physical stress, but they can be divided into two principal types, to which the body reacts in different ways. There is emergency stress, a situation that poses an immediate threat, such as a near accident in an automobile, a wound, or an injury. There is also continuing stress, such as that caused by changes in the body during puberty, pregnancy, menopause, acute and chronic diseases, and continuing exposure to excessive noise, vibration, fumes, chemicals, or other agents.

The body's reaction to emergency stress is set off by the adrenal medulla. The medulla of each adrenal gland is directly connected to the nervous system. When an emergency arises, it pours the hormone epinephrine into the bloodstream. This has the effect of speeding up the heart and raising the blood pressure, emptying sugar supplies swiftly into the blood, and dilating the blood vessels in the muscles to give them immediate use of this energy. At the same time, the pupils of the eyes dilate. (See also alarm reaction.)

The reaction of the body to continuing stress is even more complex. Again the principal organs are the adrenal glands, but after the first phase of alarm, the glands continue to produce a steady supply of hormones that apparently increase the body's resistance. This is in addition to specific defenses such as the production of antibodies to fight infection. If the stress is overwhelming, as in the case of an extensive third-degree burn or an uncontrollable infectious disease, the third phase, exhaustion of the adrenal glands, sets in, sometimes with fatal results.
Psychologic Stress. The emergency response of the body comes into play when a person merely foresees or imagines danger, as well as in real emergency situations. The thought of danger, or the vicarious experience of it in a thrilling story, play, or film, may be enough to cause the muscles to tense and the heart to start pounding. Psychologic situations can have the same effect. One of the best-known examples of this is “stage fright,” often characterized by tensed muscles and an increased heart rate. At times the person may not even be aware of the unconscious thought that produces this dramatic reaction.
Stress and Disease. In recent decades, there have been numerous attempts to find a direct correlation between certain diseases and a stressful environment or a personality type that responds to the environment in a certain way. However, while inappropriate activity and a hectic lifestyle can cause illness in some persons, a busy and productive person can actually be subject to less stress than one who feels trapped in a limited position with no hope for release or a sense of accomplishment.

The diseases most often associated with a stressful environment are, according to some scientists, coronary artery disease and “heart attack,” high blood pressure, and cancer. Studies of laboratory animals have demonstrated a connection between isolated and specific stimuli such as electric shock and separation from mates and the development of heart disease in these animals. The stressful variables in the human environment are, however, much more complex, and a stressful environment can be related to heart disease only as a risk factor (see type a behavior).

The postulated relationship between stress and the development of a malignancy is based on the theory that destructive emotions affect and in some way weaken the body's surveillance system, causing its immune response to fail to recognize and destroy malignant cells.

Although relaxation techniques can reduce blood pressure in persons with mild hypertension, there is no evidence that tension and stress cause the blood pressure to rise and stay at levels above normal.

Other diseases considered by some researchers to be related to stress include asthma, allergies, colitis, migraine headaches, and peptic ulcers. Even though the relationship is not clear and there are currently no hard data to support this, most health care providers are convinced that stress contributes to the worsening of symptoms and influences the impact a disease will have on the lives of some patients while other patients adapt to stress and seem to have no long-term deleterious reaction to it.
Coping Mechanisms. Unhealthy ways to cope with psychologic stress include drug abuse and alcoholism, smoking, abusive and violent behavior, and working harder to accomplish unrealistic or poorly defined goals. In order to deal with stress in an effective and healthy way, one must first identify sources of stress, either within oneself or in one's environment.

Job stressors are frequently related to disorganization in the work place, poor time management, and unrealistic or uncommunicated expectations of the employer. Another source of stress for the working person may be the lack of time for family and recreation because of job demands. Once job stressors are identified, some options are to change the stressful situation, modify the way one responds to stressors, or seek another job that is less stressful. In some instances learning to be more assertive and better able to communicate with supervisors and coworkers can reduce job-related stress.

Stressors in the home environment include negative self-concept; inadequate physical, cognitive, or behavioral resources; poor problem-solving skills; marital discord; ineffective parenting or lack of parenting skills; and lack of family support. Effective coping may require strategies to improve self-concept and build self-esteem, develop problem-solving skills, learn effective parenting, and establish a network of people who can give support. Exercise, improving one's nutritional status, making time for recreational activities, and utilizing relaxation techniques to relieve tension can also be healthy ways to cope with stress.

Etymology: OFr, estrecier, to tighten
any emotional, physical, social, economic, or other factor that requires a response or change. Examples include dehydration, which can cause an increase in body temperature, and a separation from parents, which can cause a young child to cry. Stress can be positive or negative. Ongoing chronic stress can result in physical illness. Stress has been theorized as a major contributing factor in many physical diseases, such as asthma. Stress may also be applied therapeutically to promote change, such as implosive therapy for phobic patients, in which the patient is given support while being exposed to the situation that produces anxiety and is thereby gradually desensitized. The nature and degree of stress observed in a patient are frequently evaluated by the nurse as part of the ongoing holistic nursing assessment. See also general adaptation syndrome.

Any physical, social or psychological factor or combination of factors that acts on the individual so as to threaten his or her well-being and produce a physiological, often defensive, response. The response to stress may be beneficial, distressing or, occasionally, dangerous. Responses such as the production of ADRENALINE and CORTICOSTEROIDS, raised heart rate and blood pressure, increased muscle tension and raised blood sugar, are natural; but persistent civilized suppression of the natural physical concomitants (fight or flight) may be damaging. Most medical scientists view with scepticism the proposition that many human diseases are caused by stress. There is, however, no questioning the fact that overwhelming stress can cause physical and psychological damage. See POST-TRAUMATIC STRESS DISORDER.

An instrument for examining substances in polarized light. It consists of a polarizer and an analyser with their planes of polarization at right angles to each other. In the regions where the material is stressed (such as an ophthalmic lens tightly mounted in a metal frame) it becomes birefringent and the observer sees a system of dark fringes in that region. When used to detect strain in glass or plastic it is called a strain tester. Safety glass (except the chemically strengthened type) displays a characteristic strain pattern when viewed in a polariscope. See safety glass; strain.
