Secret to longevity uncovered: Researchers identify key personality trait in centenarians

Scientists exploring the secrets of healthy longevity have identified a crucial missing element beyond genetics, diet, exercise, and social connections: personality. A new study conducted by researchers at the University of Cagliari in Italy focused on residents of Sardinia, home to one of the world's "blue zones" known for exceptionally high numbers of centenarians.

The research, published in the International Journal of Applied Positive Psychology, aimed to understand if personality traits correlate with mental well-being and health-related quality of life (HRQoL). Previous studies on blue zones indicated higher levels of resilience, psychological well-being, and optimism, but lacked detailed personality assessments.

Researchers analyzed 125 participants aged 71 to 101, with 55 living within the blue zone and 70 nearby. They assessed mental and physical health, lifestyle, hobbies, and personality using the Big Five model (openness, conscientiousness, extraversion, agreeableness, and neuroticism). The findings revealed a striking difference: blue zone residents exhibited significantly higher levels of openness to experience.

These individuals displayed greater curiosity and interest in learning, along with a readiness to explore new ideas and try unfamiliar things. They also demonstrated superior problem-solving skills, higher emotional competence, and dedicated more time to intellectually or physically engaging leisure activities. Overall, the study highlighted the significant roles of openness and conscientiousness in fostering better mental well-being and a tendency to spend more time on enriching pursuits.
