 It's a fascinating study because we've long known that anger has been associated with problems with our heart. But in this study, they were actually to gather participants, almost 300, and they were able to subject them to different emotional experiences. And what they found that anger was most likely associated with the malfunctioning of specific blood cells or epithelial cells. And that's important because that can lead to hardening of the blood, the blood vessels over time. And then that can lead to increased risk of heart attacks, strokes and cardiovascular disease.
