Health, however, is more than the mere absence of disease. In an article published this week in the Psychological Bulletin, my colleague Laura Kubzansky and I demonstrate that positive psychological well-being – which includes feeling optimistic, happy, satisfied, and purposeful – is beneficial for cardiovascular health.
In an investigation of more than 200 studies, we found that these psychological assets are associated with a reduced risk of cardiovascular disease, the leading cause of death in the United States. This relationship was present regardless of a person’s age, socioeconomic status, smoking status, or body mass index.
Moreover, positive psychological well-being seems to be connected to better cardiovascular outcomes because people with greater well-being tend to engage in healthier behaviors like exercising and have healthier biological function like low cholesterol. These findings align with the American Heart Association’s recent emphasis on ideal cardiovascular health, which it defines as more than the absence of risk factors.
