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 .
Treatment of mild hypertension with progressive muscle relaxation. Predictive value of indexes of sympathetic tone.
Effects of progressive muscle relaxation ( PMR ) and of attention control were investigated in a prospect i ve r and omized trial of borderline or mild hypertensive patients . Both groups received placebo and had the same number of clinic return visits . After 22 weeks the average mean home BP in PMR decreased 3 mm Hg , whereas in controls BP increased 2 mm Hg . Progressive muscle relaxation had no significant effect on the clinic BP . The response to PMR was not uniform . Responders were characterized by faster heart rates and higher plasma norepinephrine levels . The responders also showed a decrease of anxiety scores during the trial . Progressive muscle relaxation is a time-consuming procedure . Blood pressure responses do not substantially exceed the placebo effects in unselected patients . However , relaxation may be suitable for young , anxious patients with mild hypertension who have a high resting sympathetic tone
