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 .
Relaxation and stress management in the treatment of essential hypertension.
Thirty-two male and female hypertensives , 34 to 65 yr of age , systolic blood pressure ( SBP ) less than 200 mmHg and diastolic blood pressure ( DBP ) between 90 and 109 mmHg , were r and omly allocated to receive either relaxation and stress management ( experimental condition ) or mild physical exercise ( control condition ) . Half the participants were taking antihypertensive drugs , which were constant for six months prior to the study and controlled during the study . Outcome measures included various measures of blood pressure in the clinic and at home , cardiovascular responsiveness , moods and 24-hr urinary adrenaline and noradrenaline . The study schedule consisted of 3-months baseline , 10 weeks treatment and 3-months follow-up . Relaxation was superior to the control procedure in reducing blood pressure as assessed by nurses blind to the participants ' treatment at post-treatment for DBP and at follow-up for DBP and SBP
