Feeling angry constricts blood vessels in unhealthy ways and could raise a person's long-term odds for heart disease, new research warns.
“We’ve long suspected, based on observational studies, that anger can negatively affect the heart. This study in healthy adults helps fill a real knowledge gap and shows how this might occur,” said Laurie Friedman Donze. She's a psychologist and program officer in the Clinical Applications and Prevention Branch of the National Heart, Lung, and Blood Institute , which funded the study.
All of the participants were monitored for blood vessel changes in their dominant arms, and then asked to engage in very personal eight-minute talks or readings that elicited various emotional states — anger, sadness, anxiety or no heightened emotion at all .This wasn't observed among people in states of either anxiety or sadness, the team noted.
He said it's not yet clear how anger impairs blood vessel dilation. Perhaps it activates the autonomic nervous system, stress hormones or inflammation of the arteries, Shimbo said. Only further research can reveal exact mechanisms, he added.
