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.
People who have positive psychological well-being may be more likely to engage in heart-healthy behaviors such as exercising, eating a healthy diet, and avoiding smoking, all behaviors that also reduce their risk of cardiovascular disease. These researchers reviewed the evidence linking well-being and health behaviors, and described strategies to enhance well-being studied by others, and the implications for cardiovascular health.
Positive psychological well-being, especially optimism, protects against the incidence, and somewhat against the progression, of cardiovascular disease through a broad array of mechanisms, according to this extensive literature review.
