Impact on Blood Pressure
After three months, researchers say blood pressure significantly decreased, by nearly 6 mmHg, among those who listened to music. It decreased by 5 mmHg among those who took part in sessions designed to make them laugh.
Blood pressure readings taken immediately after music sessions were lower by nearly 6 mmHg, and by 7 mmHg immediately after laughter sessions.
People in the comparison group showed no change in blood pressure readings.
