Background: Lifestyle including exercise and stress management has been demonstrated to reduce hypertension. It has been suggested that restorative yoga has the potential to lower blood pressure (BP) more than other lifestyle changes. Rigorous studies comparing restorative yoga to other lifestyle changes are lacking.
Procedure: Seventy eight individuals were screened and forty-five healthy volunteers were randomized into a quiet relaxation group, a stretching group, and a restorative yoga group. The relaxation group sat quietly for 15 minutes in. The stretching group performed stretching exercises for 15 minutes. The yoga intervention group performed restorative yoga for 15 minutes. Participants had blood pressure and heart rate measured at baseline, 15 minutes post intervention and 24 hours later.
Results: There were no significant differences at baseline. No significant difference between baseline, 15 minutes after, and 24 hours later were noted in the quiet relaxation group. The stretching group had a 7.1% (p<0.0001) reduction in systolic BP and saw similar reductions in diastolic BP, and HR but returned to baseline after 24 hours. The restorative yoga group saw significantly greater reductions in systolic BP more than the other groups, by 19.5% (p<0.0001) directly after the intervention and by 9.5% (p=0.0003) 24 hours later. Similar results were found for diastolic BP and HR.
Conclusions: Quiet relaxation had minimal effects on HR, diastolic BP or systolic BP; stretching and restorative yoga both appeared to reduce BP and HR. However, restorative yoga appeared to have significantly greater reductions. These reductions in BP and HR in the restorative yoga group persisted 24 hours later. This suggests the potential of restorative yoga as a therapeutic option for hypertensive patients.
