The role of purpose in life in healthy aging: implications for the Semmelweis Study and the Semmelweis-EUniWell Workplace Health Promotion Model Program.

The global aging population presents significant challenges to public health systems, particularly in countries like Hungary, which faces some of the least favorable health indicators in the European Union. To address these challenges, Purpose in Life (PIL) has emerged as a critical determinant of healthy aging, influencing physical, mental, and social health. Defined as a sense of meaning, direction, and intentionality, PIL promotes resilience, mitigates age-related decline, and fosters well-being. This review explores the theoretical frameworks, mechanisms, and practical implications of PIL in the context of aging. Biologically, PIL regulates stress responses, contributing to reduced disease risk and improved longevity. Psychologically, PIL fosters resilience, self-regulation, and positive emotions, which buffer against mental health challenges and support cognitive health. Socially, PIL strengthens meaningful relationships, promotes prosocial behaviors, and fosters collective purpose, reducing isolation and enhancing social cohesion. These mechanisms interact to create a synergistic effect that supports healthy aging trajectories. The Semmelweis Study, Hungary's most extensive workplace cohort study, offers a unique opportunity to integrate PIL assessment into its longitudinal design, providing novel insights into how PIL influences aging outcomes. Complementing this research, the Semmelweis-EUniWell Workplace Health Promotion Program translates these insights into actionable interventions, designed to enhance employee well-being and productivity. Drawing from global best practices, including insights from Blue Zones and Mediterranean-inspired interventions, Hungary can position PIL as a cornerstone of its healthy aging agenda. Incorporating PIL-focused strategies into workplace health programs and national public health policies holds the potential to extend healthspan, reduce healthcare costs, and foster a resilient and purposeful aging population. This review highlights the transformative potential of PIL in addressing the multifaceted challenges of aging and advancing public health goals.
