Prospective data from the Health and Retirement Study, a nationally representative study of older US adults, was analyzed to examine the relationship between optimism and heart failure, adjusting for sociodemographic, biological, behavioral, and psychological covariates. Higher optimism was associated with a lower risk of incident heart failure during the follow-up period, and these effects persisted when accounting for covariates.
Health—whether psychological or physical—is characterized not just by the absence of disease but increasingly by the presence of well-being. These researchers looked at the relationship between psychological well-being (marked by optimism, happiness, and life purpose) and serum antioxidants such as carotenoids and Vitamin E, which are indicators of physical health.
Research suggests that optimistic individuals are more likely to live a healthier and longer life. However, more longitudinal studies are necessary to learn more about when, why, how and for whom optimism plays a role in good health and whether interventions that enhance optimism will yield health benefits.
