This study compared 125 older adults (71–101 years) from Sardinia's Blue Zone versus a nearby non-Blue Zone. Openness, conscientiousness, and agreeableness correlated with better psychological well-being; neuroticism correlated with lower Health-Related Quality of Life (HRQoL). Blue Zone residents showed higher openness, better coping and emotional competence, and more leisure engagement than non-Blue Zone peers, suggesting adaptive personality traits and active lifestyles jointly support successful aging in this exceptional-longevity population.

This narrative review of 31 studies finds that chronic stress is consistently associated with higher neuroticism and lower levels of the remaining four Big Five traits. The neuroticism link is the strongest and most well-replicated; evidence for reduced conscientiousness is moderate; associations with extraversion, agreeableness, and openness are meaningful but largely cross-sectional. The relationship is likely bidirectional, and social support, coping strategies, and socioeconomic status all moderate these effects.

Using data from over 30,000 participants, this study links the Big Five personality traits to dietary habits, exercise, and obesity. Conscientiousness emerged as a key predictor of health, correlating with recommended food intake, higher physical activity, and lower obesity risk. Conversely, Neuroticism was associated with poor dietary choices and increased obesity. Interestingly, Openness and Extraversion showed mixed results, linking to both healthy and unhealthy eating habits. These findings suggest that while personality is stable, understanding these behavioral patterns can help tailor effective, individualized health interventions.

This systematic review finds that employment is generally associated with better health outcomes, especially in reducing depression and improving overall mental well-being. However, evidence on its impact on specific physical health conditions and mortality remains limited. The authors highlight the need for further research to better understand how employment influences these areas and to address existing gaps in the literature.

The Big Five personality factors serve as powerful heuristics for predicting outcomes across multiple life domains. At the individual level, traits are linked to health, happiness, and identity. Interpersonally, they shape the quality of family and romantic relationships. Finally, at the institutional level, personality influences occupational success, political ideology, and community involvement. These findings underscore that personality dispositions are not just internal states but active drivers of significant life consequences.

This meta-analysis explains why Conscientiousness is such a powerful predictor of a long life. By reviewing nearly 200 studies, researchers found that highly conscientious people consistently avoid risky behaviors (such as tobacco use, excessive drinking, and reckless driving) while actively engaging in beneficial habits like regular exercise and healthy eating. These findings demonstrate that personality doesn't just impact your mind; it physically protects your body by shaping your daily lifestyle choices.

This meta-analysis identifies hostility as an independent risk factor for coronary heart disease (CHD) and all-cause mortality. The research distinguishes between different measurement methods, finding that structured interviews focusing on the 'potential for hostility' are particularly effective at predicting CHD. Meanwhile, cognitive-experiential measures, such as the Cook-Medley Hostility Scale, prove highly predictive of overall mortality. Despite an increase in null findings from recent high-risk studies, the overall evidence suggests that chronic hostility functions as a significant psychological contributor to cardiovascular decline and shortened lifespan.

This longitudinal study analyzed the early-life autobiographies of 180 nuns to determine if emotional content predicts longevity. Researchers discovered a powerful inverse relationship between positive emotions expressed at age 22 and mortality risk between ages 75 and 95. Those in the highest quartile of positive emotion lived significantly longer, showing a 2.5-fold lower risk of death compared to the lowest quartile. These findings suggest that a positive emotional baseline in early adulthood serves as a long-term predictor of survival decades later.

This study of 343 participants highlights Conscientiousness as a vital predictor of health-conscious behaviors, particularly those involving household safety. High levels of this trait led to more restrictive smoking rules at home, suggesting that self-disciplined individuals are more proactive in protecting their environment. Interestingly, perceiving health risks only reduced smoking within the home for those high in Conscientiousness, indicating that personality acts as a necessary catalyst for turning health concerns into actual lifestyle changes.

This meta-analysis of 45 studies identifies hostility as an independent risk factor for coronary heart disease (CHD) and all-cause mortality. Using structured interviews to measure hostile potential yielded a correlation of r=.18 with CHD. Notably, the Cook-Medley Hostility Scale and similar cognitive measures were significant predictors of mortality (r=.16), even after controlling for traditional medical risk factors. While recent high-risk studies have introduced more null findings, the overall data suggests that a hostile personality profile significantly impacts long-term cardiovascular health and longevity.

This longitudinal study followed a cohort of gifted children across several decades to determine how personality and family stress impact longevity. Researchers discovered that psychosocial factors, particularly impulsive or undercontrolled personality traits and the experience of parental divorce during childhood, serve as significant risk factors for premature death. These early-life stressors and traits also linked to unstable marriage patterns in adulthood, suggesting that long-term health is deeply influenced by the intersection of individual temperament and stable family environments.
