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 Hypertension with Biofeedback and Relaxation Techniques
& NA ; The present study describes a 16‐week trial of the use of a combination of biofeedback and relaxation techniques for the treatment of hypertension . Twenty‐two hypertensive patients were r and omly allocated to one of three groups : ( 1 ) diastolic blood pressure feedback , electromyographic feedback , and verbal relaxation ; ( 2 ) sham blood pressure feedback ; and ( 3 ) no treatment . For the 14 patients completing active treatment during an initial or crossover period , the average changes in blood pressure as measured outside the laboratory were minimal ( 0/−1 and + 1/0 mm Hg , supine and st and ing , respectively ) . Average blood pressure reduction in the laboratory was no greater with active than with sham blood pressure feedback ( −3/−2 vs. −5/−2 mm Hg ) . One subject , however , after showing no change in blood pressure during sham feedback , achieved pronounced and prolonged improvement following active treatment . Overall results do not support the usefulness of these techniques as primary therapy in most hypertensives
