Robust statistically significant effects were found for improved diet , aerobic exercise , alcohol and sodium restriction , and fish oil supplements : mean reductions in systolic blood pressure of 5.0 mmHg [ 95 % confidence interval ( CI ) : 3.1 - 7.0 ] , 4.6 mmHg ( 95 % CI : 2.0 - 7.1 ) , 3.8 mmHg ( 95 % CI : 1.4 - 6.1 ) , 3.6 mmHg ( 95 % CI : 2.5 - 4.6 ) and 2.3 mmHg ( 95 % CI : 0.2 - 4.3 ) , respectively , with corresponding reductions in diastolic blood pressure .
Relaxation significantly reduced blood pressure only when compared with non-intervention controls .
We found no robust evidence of any important effect on blood pressure of potassium , magnesium or calcium supplements .
Available evidence does not support relaxation therapies , calcium , magnesium or potassium supplements to reduce blood pressure
PURPOSE To quantify effectiveness of lifestyle interventions for hypertension .
Efficacy of relaxation techniques in hypertensive patients.
We examined 117 out patients ( 20- to 45-year-old men ) with mild essential hypertension before treatment , after the main treatment course ( 6 weeks ) , and at 12-month follow-up . The patients were r and omized into two major groups : ( a ) a treatment group that received autogenic training ( 23 patients ) , biofeedback ( 24 patients ) , or breathing-relaxation training ( 23 patients ) and ( b ) a control group that consisted of 24 patients who did not receive any intervention and 23 patients who were treated with a " psychological placebo . " Clinical , psychological , and psychophysiological data from all patients who were offered relaxation therapy were analyzed . By the end of follow-up , and compared to the control group , the treatment group demonstrated a significant reduction in systolic and diastolic blood pressures , peripheral vascular resistance , and hypertensive response to emotional stress , and an improvement in psychological adaptation , quality of life , and capacity for work . Comparative analysis of the efficacy of different relaxation methods revealed that biofeedback and breathing-relaxation training result ed in the greatest reduction in blood pressure . The antihypertensive effect of relaxation therapy correlated positively with pretreatment blood pressure levels and negatively with the duration of illness and certain psychological features
