This review investigates the association between positive psychological well-being (PPWB) and cardiovascular disease (CVD). We also consider the mechanisms by which PPWB may be linked with CVD, focusing on the health behaviors (e.g., smoking, alcohol consumption, physical activity, sleep quality and quantity, and food consumption) and biological functions (e.g., cardiovascular, inflammatory, and metabolic processes) that are most relevant for cardiovascular health. Because PPWB is a broad concept, not all aspects of PPWB may be associated with cardiovascular health. Thus, we distinguish between eudaimonic well-being, hedonic well-being, optimism, and other measures of well-being when reviewing the literature. Findings suggest that PPWB protects consistently against CVD, independently of traditional risk factors and ill-being. Specifically, optimism is most robustly associated with a reduced risk of cardiovascular events. In general, PPWB is also positively associated with restorative health behaviors and biological function and inversely associated with deteriorative health behaviors and biological function. Cardiovascular health is more consistently associated with optimism and hedonic well-being than with eudaimonic well-being, although this could be due in part to more limited evidence being available concerning eudaimonic well-being. Some similarities were also evident across different measures of PPWB, which is likely due to measurement overlap. A theoretical context for this research is provided, and suggestions for future research are given, including the need for additional prospective investigations and research that includes multiple constructs of psychological well-being and ill-being.Keywords: cardiovascular disease, health behaviors, biological function, eudaimonic well-being, hedonic well-being Scholars have long recognized the connection between mental health and physical health. From the ancient Roman poet Juvenal who declared, "A healthy mind in a healthy body," to early 20th century psychoanalysts who investigated the connection between mental states and physiology (Menninger & Menninger, 1936), and to researchers in the late 20th century seeking to identify disease-prone personalities (H. S. Friedman & Booth-Kewley, 1987;Rosenman et al., 1964), the complex relationship between psychological attributes and physical ailments has been the subject of fascination across time. Although past research has predominantly focused on the relationship between poor psychological functioning (e.g., anxiety, depression, hostility) and physical health, increasing research also suggests that a protective relationship exists between positive psychological functioning and physical health (Diener & Chan, 2011;Pressman & Cohen, 2005). Because the effects of psychological well-being and psychological ill-being are not merely opposites of one another and the absence of one does not necessarily indicate the presence of the other (Ryff et al., 2006;Ryff & Singer, 1998), it is critical to consider each separately in rel...

An 8-months long experimental study examined the immediate and longer-term effects of regularly practicing two assigned positive activities – expressing optimism and gratitude – on well-being. More important, this intervention allowed us to explore the impact of two meta-factors that are likely to influence the success of any positive activity – whether one self-selects into the study knowing that it is about increasing happiness and whether one invests effort into the activity over time. Our results indicate that initial self-selection makes a difference, but only in the two positive activity conditions, not the control; and that continued effort also makes a difference, but again only in the treatment conditions. We conclude that happiness interventions are more than just placebos, but that they are most successful when participants know about, endorse, and commit to the intervention.

Past research has demonstrated a relationship between happiness and workplace success. For example, compared with their less happy peers, happy people earn more money, display superior performance, and perform more helpful acts. Researchers have often assumed that an employee is happy and satisfied because he or she is successful. In this article, the authors review evidence in support of an alternative hypothesis-namely, that happiness is a source of why particular employees are more successful than others. To this end, the authors consider evidence from three types of studies-cross-sectional, longitudinal, and experimental-that relate happiness to various work outcomes. Taken together, the evidence suggests that happiness is not only correlated with workplace success but that happiness often precedes measures of success and that induction of positive affect leads to improved workplace outcomes.

Facets of positive psychological well-being, such as optimism, have been identified as positive health assets because they are prospectively associated with the 7 metrics of cardiovascular health (CVH) and improved outcomes related to cardiovascular disease. Connections between psychological well-being and cardiovascular conditions may be mediated through biological, behavioral, and psychosocial pathways. Individual-level interventions, such as mindfulness-based programs and positive psychological interventions, have shown promise for modifying psychological well-being. Further, workplaces are using well-being-focused interventions to promote employee CVH, and these interventions represent a potential model for expanding psychological well-being programs to communities and societies. Given the relevance of psychological well-being to promoting CVH, this review outlines clinical recommendations to assess and promote well-being in encounters with patients. Finally, a research agenda is proposed. Additional prospective observational studies are needed to understand mechanisms underlying the connection between psychological well-being and cardiovascular outcomes. Moreover, rigorous intervention trials are needed to assess whether psychological well-being-promoting programs can improve cardiovascular outcomes.

Growing evidence suggests that well-being interventions can be effective. However, it is unclear whether happiness-increasing practices are equally effective for individuals from different cultural backgrounds. To investigate this question, Anglo Americans and predominantly foreign-born Asian Americans were randomly assigned to express optimism, convey gratitude, or list their past experiences (control group). Multi-level analyses indicated that participants in the optimism and gratitude conditions reported enhanced life satisfaction relative to those in the control condition. However, Anglo Americans in the treatment conditions demonstrated larger increases in life satisfaction relative to Asian Americans, while both cultural groups in the control condition showed the least improvement. These results are consistent with the idea that the value individualist cultures place on self-improvement and personal agency bolsters the efforts of Anglo Americans to become more satisfied, whereas collectivist cultures’ de-emphasis of self-focus and individual goals interferes with the efforts of Asian Americans to pursue enhanced well-being.

Empirical research demonstrates a relationship between happiness and career success. For example, happy people receive higher earnings, exhibit better performance, and obtain more favorable supervisor evaluations than their less happy peers. Researchers have posited that success leads to happiness, but Boehm and Lyubomirsky reviewed the relevant research in 2008 and argued that the alternative hypothesis-that happiness causes success-may be equally plausible. A decade later, we return to the literature to supplement studies we previously cited with new research and to determine whether the results of cross-sectional, longitudinal, and experimental investigations provide additional support for this hypothesis. We conclude that the evidence continues to persuasively suggest that happiness is correlated with and often precedes career success and that experimentally enhancing positive emotions leads to improved outcomes in the workplace.

Objective Research suggests that positive psychological well-being is associated with cardiovascular health. However, much of this research uses elderly samples and has not determined the pathways by which psychological well-being influences cardiovascular disease or whether effects are similar for men and women. This study investigates the association between two aspects of well-being (emotional vitality and optimism) and coronary heart disease (CHD) in a sample of middle age men and women, and considers potential mediating factors. Methods Between 1991 and 1994, well-being and coronary risk factors were assessed among 7,942 individuals without a prior cardiovascular event from the Whitehall II cohort. Incident CHD (fatal CHD, first nonfatal myocardial infarction, or first definite angina) was tracked during 5 person-years of follow-up. Results Positive psychological well-being was associated with reduced risk of CHD with an apparent threshold effect. Relative to people with the lowest levels of well-being, those with the highest levels had minimally-adjusted hazard ratios of 0.74 (95% confidence interval: 0.55-0.98) for emotional vitality and 0.73 (95% confidence interval: 0.54-0.99) for optimism. Moreover, the association was strong for both genders and was only weakly attenuated when accounting for ill-being. Neither health-related behaviors nor biological factors explained these associations. Conclusions Positive psychological well-being was associated with a modest but consistent reduced risk of incident CHD. The relationship was comparable for men and women, and was maintained after controlling for cardiovascular risk factors and ill-being. Additional research is needed to identify underlying mechanisms and investigate whether interventions to increase well-being may enhance cardiovascular health.
