Do you enjoy listening to the sounds of the ocean waves crashing against the shore, or the calming sounds of a relaxation CD to help you unwind after a stressful day? According to new research, these sounds might not only calm and soothe your soul; they may also help to lower your blood pressure.
The study tested 41 elderly men and women who had hypertension. 20 participants were asked to listen to a 12-minute-long relaxation CD, while the remaining 21 participants were asked to listen to a 12-minute-long CD of a Mozart sonata. Both groups were asked to listen to their CD three times a week for four months.
The results showed a drop in blood pressure by an average 6.4% in those listening to the relaxation CD, compared to nearly 5% in those who listened to the Mozart CD. The reduction in systolic blood pressure was statistically significant in both groups; however the reduction in diastolic blood pressure was not statistically significant in either group.
"A 3-5% change has been used as the cutting point in clinical research. It has been suggested that a 5 mmHg reduction in systolic blood pressure would result in a 9% reduction in coronary heart disease related death and 14% reduction in stroke related death," Jean Tang (who conducted the study) said in a news release issued by the American Heart Association. This program may provide another way to help manage hypertension or blood pressure.
