Stress factors, especially high levels of occupational stress, are associated with hypertension. Several so-called psychological techniques have been applied to hypertension: biofeedback, relaxation techniques (Schultz' autogenic training, Jacobson's progressive relaxation), transcendental meditation, and cognitive behavioral techniques for stress management. Randomized studies show that the best results come from cognitive behavioral methods, whether or not they include relaxation techniques. Other forms of psychotherapy (such as psychoanalysis) may be useful, although their benefits for blood pressure have not been tested in controlled trials. Patients should be informed about the personal benefits they may obtain from psychological treatment. Indications are hyperreactivity to stress, high levels of occupational stress, and difficulty in tolerating or complying with antihypertensive drugs.
