Death is a universal truth, yet people's views toward death vary widely across psychological and cultural situations. These attitudes affect older persons' mental well-being, end-of-life decisions, and overall life satisfaction. This review compiles data from 25 empirical studies that investigate the psychological, spiritual, and cultural aspects of death attitudes in later life. The paper uses cross-cultural research to investigate how religiosity, spirituality, meaning-making, and cultural worldviews influence acceptance, fear, and avoidance of death. The findings show that spirituality and strong religious views are consistently associated with lower death anxiety and greater peaceful acceptance. Individuals who lack existential purpose or social connectedness, on the other hand, are more fearful and avoidant. Cultural context is an important moderator: Western civilisations frequently understand death through individualistic and existential frameworks, whereas Eastern traditions see dying as a natural movement along a spiritual or social continuum. Gender, physical health, and life satisfaction all have an impact on how older persons think and feel about death. The review uses psychological theories to explain coping mechanisms and meaning reconstruction, including Gerotranscendence, Logotherapy, and Terror Management Theory. Overall, data suggest that fostering purpose, spiritual meditation, and acceptance of mortality improves resilience and psychological integration as people age. This research highlights the importance of comprehending death attitudes for end-of-life care as well as for fostering dignity, peace, and purpose in the latter phases of human development by integrating cross-cultural and psychological viewpoints.
