Bringing stress under better control—through nutrition, lifestyle changes, and specific techniques—may improve outcomes in a variety of health conditions. Research suggests that psychological outlook and stress physiology can influence immune function and disease progression.
An article published in Medical Tribune (February 10, 1994;28) reviewed research indicating that stress reduction may be supportive for patients with serious illnesses, including cancer and HIV/AIDS. In one large observational study of approximately 800 HIV-positive patients, individuals with a pessimistic outlook about their health became ill sooner and had shorter survival times than those with a more positive outlook. These findings suggest that psychological factors may influence disease progression, though they do not replace medical treatment.
Stress management has also been studied in cardiovascular disease. Research published in The Journal of the American Medical Association (April 6, 2005;293(13):1626–1634) found that a combined program of exercise and stress management improved outcomes in patients with ischemic heart disease. Earlier research in Archives of Internal Medicine (October 27, 1997;157:2213–2223) followed 136 patients with coronary artery disease who participated in either an exercise program or a structured stress-management program. Over a 38-week follow-up period, patients in the stress-management group experienced significantly fewer cardiac events than controls, with a relative risk of 0.26. The exercise group also showed benefit, though less pronounced than the stress-management group.
Patients with irritable bowel syndrome (IBS) also appear to respond to stress-reduction strategies. A study published in Digestion (1991;50:36–42) divided 35 IBS patients into two groups, one receiving standard care and the other receiving stress-management training that included education, breathing exercises, and relaxation techniques. More than 60% of patients in the stress-management group experienced fewer episodes, and their symptoms were less severe. Additional research in The American Journal of Gastroenterology (1994;89(8):1219–1225) found that psychological stress was associated with increased symptom severity and mucosal abnormalities in patients with ulcerative colitis.
Other conditions that may benefit from stress-reduction strategies include chronic fatigue syndrome, fibromyalgia, depression, eczema, allergies, and asthma. Stress-related hormonal changes can alter immune function and white blood cell activity. While stress management is not a cure, reducing cumulative stress can support overall health and may improve the body’s ability to cope with disease.
