Awareness of mortality and death profoundly shapes human cognition, emotions, values, and behaviour. This paper distinguishes the related yet conceptually distinct constructs of mortality awareness and death awareness, examining their similarities, differences, and implications for psychological functioning. While mortality awareness encourages reflection on life’s finitude, meaning, legacy, and long-term purpose, death awareness evokes more immediate recognition of life’s fragility and emotional responses to mortality. Drawing upon interdisciplinary literature in psychology, thanatology, and existential studies, the paper explores how these forms of awareness influence existential anxiety, value prioritisation, decision-making, interpersonal relationships, risk perception, cultural and religious beliefs, and coping mechanisms. It argues that confronting mortality can foster greater self-awareness, resilience, intentional living, and personal growth when appropriately processed. The discussion provides practical insights for educators, counsellors, therapists, and other helping professionals seeking to understand how mortality-related awareness influences human perception and behaviour, particularly when supporting individuals facing terminal illness, bereavement, or major life transitions.
