Diet, exercise and social ties often dominate discussions of healthy aging, yet researchers highlight another element. A study in Sardinia, Italy, one of the Blue Zones known for high numbers of centenarians, points to personality as a significant factor. Personality shapes responses to challenges and influences habits that support activity in later years, according to psychologist Maria Chiara Fastame and colleagues at the University of Cagliari. Their findings indicate that adaptive traits combined with coping skills encourage an active lifestyle and offer clues about successful aging. Isolating personality’s role remains complex because genes and surroundings also affect aging. Blue Zones attract interest due to longer lifespans and lower disease rates. The team examined 125 adults aged 71 to 101, including 55 from the Sardinian Blue Zone and 70 from a similar nearby area with comparable socioeconomic conditions and healthcare access. Participants completed assessments of mental and physical health, leisure activities and the Big Five personality traits. Blue Zone residents showed notably higher openness, reflecting greater curiosity, interest in learning and willingness to try new experiences. They also demonstrated stronger coping abilities, emotional skills and more time spent on stimulating hobbies. Across all participants, higher openness correlated with improved psychological well-being and hobby engagement, while higher conscientiousness linked to greater life satisfaction and coping. Higher neuroticism associated with lower health-related quality of life. Researchers suggest personality indirectly supports longevity by promoting behaviors such as seeking experiences, maintaining connections and staying active. The observational study was small and cannot prove causation, so further research is required to clarify these links.
