This literature review synthesises research on the relationship between personality development and health perceptions, focusing on how specific personality traits influence individuals' health-related views and behaviours. Through an examination of empirical and theoretical literature, the review highlights the significant roles of neuroticism, conscientiousness, and extraversion in shaping health perceptions. Key findings reveal strong links between these traits and health outcomes, with neuroticism associated with poorer health perceptions and conscientiousness linked to healthier behaviours and perceptions. The paper identifies gaps in current research, particularly in understanding the underlying mechanisms and the effectiveness of tailored interventions. The review concludes with recommendations for future research, emphasising the need for longitudinal and culturally diverse studies to advance the field.
