Re: Found the true cause of AF

More information to confirm that allowing your anger to run is beneficial.  I have left in the links to the sources.

....Studies have found that suppressing anger can worsen the experience of pain and put stress on people’s cardiovascular systems; pushing anger down has also been tied to anxiety and depression.

In contrast, the benefits of acknowledging and harnessing our angry energy are well-documented in scientific studies. Anger can be a motivating force that also might make people feel more optimistic and confident. Acknowledging anger can help lower stress on the heart and manage pain, at least in laboratory studies. And expressing anger as it arises (instead of bottling it up and letting it all come out in one explosive fight) has also been found to benefit interpersonal relationships.

Perhaps more than anything else, anger benefits us by alerting us that something is wrong on an individual, interpersonal, or societal scale. In the simplest sense, anger may be one of the reasons why we no longer have segregated water fountains, why someone chooses to end a deadening career, or why a person leaves an unhealthy relationship. But does this mean we should all go around punching walls every time we get annoyed or witness injustice?
