Causes and symptoms
- 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.
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.
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.
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.

stressAny 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.
stress(1) in mechanics, the force per unit area applied to a body or object. Measured in newtons per square metre (N.m-2) or pascals (Pa); (2) the psychological and/or physiological response of an organism to any demand made upon it by agents threatening its physical or emotional well-being. stressor any factor that causes a stress response. stress management any of a range of methods used to reduce or manage the negative effects of stress, such as relaxation techniques and biofeedback. See also anxiety.
stressresisting force (within a body) to potentially deforming forces/loads incident upon that body; and distributed throughout the material sustaining the load; the greater the amount of the material subject to load, the lower the overall stress to the material
stressbody reaction to external and internal events upsetting homeostasis and ability to deal with external events; instrumental in disease onset/manifestation, e.g. ischaemic heart disease, rheumatoid arthritis and psoriasis
2. the force of energy directed against a tissue structure or against the function of tissue as the result of injury and trauma associated with fracture, burn, infection, surgical procedure, pharmacologic action, or anxiety states. The response to stress involves local metabolic function, the hormonal activity of the endocrine system regulated by the pituitary gland, and the autonomic and central nervous systems. The stress phenomenon is often associated with the general adaptation syndrome.
3. in prosthetic dentistry, forcibly exerted pressure (e.g., the pressure of the maxillary teeth against the mandibular teeth or the pressure contact of a distorted removable partial denture on the supporting teeth or ridge structures).
