Anger hurts your heart but laughter protects it.

If you are a hothead, your heart may be at risk. Several recent studies point to the link between anger and heart disease and dangerous heart events like heart attack. So think about this the next time you feel like raging at another driver or that slow person in front of you at the supermarket. Individuals who are prone to getting angry may have a higher risk for heart failure, researchers found. And in those who were hospitalized for heart failure, high anger levels were associated with a greater risk of getting readmitted.

The findings are consistent with previous studies that have evaluated the link between anger or hostility and the risks of stroke and coronary heart disease.

Last month a study found that among patients with cardiovascular disease, an angry personality profile was associated with a higher risk of MI.

That study found that anger drives heart attacks but laughter may protect you. When you are riled your blood vessels squeeze and blood flow is reduced, but a good belly laugh relaxes the arteries and enhances circulation.

And a recent meta-analysis published in the Journal of the American College of Cardiology showed that previously healthy people who were prone to anger and hostility had a greater risk for coronary heart disease events. In those who already had heart disease, anger was associated with a worse prognosis.
