Scientists studying people who live exceptionally long lives have discovered that personality may play an important role in healthy aging. While diet, exercise, and social connections are often linked to longevity, new research suggests that certain psychological traits may also influence how people experience life as they grow older.

Researchers from the University of Cagliari in Italy examined 125 adults between the ages of 71 and 101 in Sardinia, a region famous for having one of the world’s highest concentrations of centenarians. The study found that these long-lived residents consistently showed higher levels of openness, a personality trait connected to curiosity, creativity, learning, and a willingness to experience new things.

According to researchers, openness may encourage habits that support healthy aging, such as staying mentally active, developing hobbies, maintaining relationships, and continuing to learn throughout life. Participants with higher openness scores also tended to report better psychological well-being and greater involvement in meaningful activities. Other traits showed connections as well, with conscientiousness being linked to life satisfaction and stronger coping skills, while higher neuroticism was associated with lower well-being.

The researchers caution that personality alone does not determine how long someone will live. Instead, traits may influence daily decisions and behaviors that contribute to healthier aging over time. Since the study was observational and involved a limited number of participants, it cannot prove that openness directly causes longevity. However, it adds to growing evidence that mental habits and emotional well-being may work together with lifestyle choices to support a longer, healthier life.
