While occasional anger episodes pose minimal risk, recurring anger can lead to chronic injuries in blood vessels, increasing the likelihood of heart disease, according to a recent study, funded by the National Institutes of Health (NIH).
Published in the Journal of the American Heart Association (JAHA), the research highlights a link between chronic anger and impaired blood vessel function, a precursor to heart disease.
STUDY DESIGN AND FINDINGS
- The randomized, controlled study recruited 280 healthy adults aged 18 to 73 without cardiovascular risk factors or mood disorders. Participants were exposed to tasks eliciting anger, anxiety, sadness, or a neutral emotional state.
- Blood flow changes were measured in participants’ dominant arms before and after emotional tasks. Results revealed a significant reduction in blood vessel dilation among those in the anger group compared to the control group.
- This impairment persisted for up to 40 minutes post-task, suggesting a sustained negative impact of anger on vascular health.
IMPLICATIONS AND FUTURE DIRECTIONS
- Impaired blood vessel dilation is a precursor to atherosclerosis, highlighting the potential long-term consequences of chronic anger on heart health.
- While the mechanisms underlying anger’s effects remain unclear, potential factors include autonomic nervous system activation, stress hormone release, and arterial inflammation.
- Future research will explore whether these findings are applicable to older adults with existing health conditions and medications. Additionally, investigations into the role of positive emotions in mitigating anger’s effects are warranted.
ANGER MANAGEMENT STRATEGIES
Effective anger management strategies, such as exercise, yoga, deep breathing, and cognitive behavioral therapy (CBT), are crucial for individuals prone to frequent anger episodes.
The study underscores the importance of promoting holistic approaches to anger management to safeguard cardiovascular health.
