Listen to your favorite song or a joke can lower your blood pressure, maybe even as much as you reduce the salt content of your diet and can even reduce your weight by 10 pounds, or about 4.5 kg, according to preliminary results from a small study presented on Friday at American Heart Association meeting in Atlanta.
In this study, Japanese researchers found that people who participate in this group for two months once it is placed in a situation around music or laughter, they are able to lower systolic blood pressure by an average of five to six points after three months. In contrast, blood pressure readings on average in the control group receiving usual therapy unchanged.
Although relatively modest, reduction in blood pressure seen in these studies has been associated with risk of 5??% To 15% lower than deaths from heart disease or stroke, said Michael Miller, MD, director of preventive cardiology at the University of Maryland Medical Center, Baltimore .
"I think there must be some physiological effects that occur, like the relationship of mind and heart," said Miller, who was not involved in this new study but has done similar research.
Researchers at Osaka University Graduate School of Medicine conducted a study on 90 men and women aged between 40 and 74 were randomized to receive hourlong music or laughter sessions per week, or no therapy at all. In music sessions, participants listen, sing, and are free to choose their favorite music from Japanese pop, classical, or jazz. (They are also encouraged to listen to music at home.) Session includes listening to funny stories laughter Japan is somewhat similar to yoga stand-up comedy and laughter, a practice of pretending to laugh until it feels natural.
After three months, the average systolic blood pressure on a group of music and laughter has been a decline 6 mmHg and 5 mmHg, whereas in the control group no change. What's more, measurements made before and after each session of therapy revealed a decrease in shot-term dips from 6 mmHg to 7 mmHg which is indirectly related to each session.
The decline that occurred in the range of three months seem to indicate what is expected of people who go on a diet of salt, and able to lose weight up to 10 pounds or 4.5 kg range, or in people who take blood pressure-lowering drugs, Reveal Miller. He added that nevertheless the music and laughter alone is not sufficient to treat high blood pressure. "This is sort of a great natural way to improve your health, but I would not recommend for you to stop taking drugs that have been recommended by a doctor," said Miller. "Although it can increase your chances to reduce the dose of your medication."
How, exactly, music and laughter can reduce blood pressure remains unclear. The researcher who led the study, Eri Eguchi, said that with this relaxation therapy can reduce levels of cortisol, a stress hormone that can contribute to high blood pressure. And in an earlier study, Miller and colleagues showed that a good laugh and listening to upbeat music to improve the function of the inner lining of blood vessels, causing blood vessels to stretch by 30%. (Watching a horror movie or listen to scary music - like the opening scene of "Saving Private Ryan" - has the opposite effect, or vice versa) Nitric oxide yangterlepas in response to laughter or music may be "magic compound" that dilate blood vessels and lowers blood pressure, Reveals Miller again.
Vera Brandes, director of research programs in music and medicine at the Paracelsus Medical University, Salzburg, Austria, said that music and laughter can influence blood pressure through different pathways. Music is believed to affect the parasympathetic nervous system, which relaxes the body and slow the heart rate, he said, but more research is needed to understand how humor affects a person emotionally - and, in turn, responds to physical stress levels.
"Although the impact of the music or the laughter did not differ significantly in size, the mechanisms that may be only partly the same," said Brandes.
Eguchi presented the findings at the annual conference of the American Heart Association on nutrition, physical activity, and metabolism. In contrast to studies published in medical journals, research has not been thoroughly examined by other experts.
