Loneliness has emerged as a critical social determinant of health with significant implications for individual wellbeing, population health outcomes, and health equity. This paper conceptualizes loneliness as a subjective experience distinct from social isolation and examines its pathways of influence on physical, psychological, and behavioral health. Drawing on epidemiological evidence, it highlights the uneven distribution of loneliness across age, gender, and socioeconomic groups, with heightened vulnerability among disadvantaged populations. The paper further reviews advances in the measurement of loneliness, including standardized scales and complementary indicators of social connectedness, while noting challenges in cross-national comparability. Policy responses are explored across multiple sectors, emphasizing community-based interventions, urban design, digital inclusion, and integrated health services as key strategies for reducing loneliness. An equity lens underscores the need to address structural determinants and prioritize marginalized groups through targeted and universal approaches. The analysis also identifies implementation challenges such as stigma, limited resources, and governance constraints, alongside enabling factors including stakeholder partnerships and community co-design. Ultimately, the paper argues for the integration of loneliness into public health frameworks, monitoring systems, and policy agendas to promote social connectedness and improve health outcomes at scale.

Keywords: Loneliness, Social determinants of health, Health equity, Social connectedness, and Public health policy.
