In order to assess the effectiveness of the thermal biofeedback training combined with the progressive muscle relaxation therapy in the treatment of patients with essential hypertension, blood pressure, plasma cortisol and aldosterone level decline was measured on the treatment group who had the combined thermal biofeedback and progressive muscle relaxation training(N=18), and on the control group who had only the progressive muscle relaxation(N=11). Baseline blood pressure was measured four times for two weeks on both groups. For the treatment group, blood pressure was measured twice before and after each of eights sessions of thermal biofeedback training for four weeks. For control group, blood pressure was measured every two visits to a clinic for progressive muscle relaxation self-training twice before and after the self-training. Plasma cortisol and aldostrone level was measured only two times during the first and during the sixth week for both group. A significant decline of the systolic blood pressure by 15mmHg, of the diastolic blood pressure by 10mmHg, of the mean atrial pressure by 11.7mmHg and of the plasma aldostrone level by 23.5pg/ml in the treatment group.
