As defined by the World Health Organisation (WHO), health is a state of complete physical, mental, and social well-being, and not merely the absence of disease and infirmity. This definition emphasises a holistic view of health that goes beyond just the absence of illness to include the overall quality of an individual's physical, psychological, and social functioning and resources. It recognises that health is influenced by a complex interplay of biological, psychological, social, economic, and environmental factors. Achieving and maintaining health requires attention to all these dimensions and involves promoting well-being in all aspects of life. This broad definition underscores the sociological perspective on health, which examines how social factors shape health outcomes and inequalities within and between populations.
