This paper explores the relationships between quality of life and health by applying discourses from the health sector to other fields and disciplines. These relationships are based on subjective parameters such as well-being, happiness, love, pleasure, and personal satisfaction, as well as objective parameters like the satisfaction of basic needs and the needs created by a society's economic and social development. The text presents the main instruments developed in recent years for measuring quality of life and the debates they have sparked. It also discusses the semantic field where representations and actions in favor of quality of life, such as the concepts of development, democracy, quality, mode of life, and conditions of life, develop. In the context of health, the paper addresses the tendency to restrict the concept of quality of life to the biomedical area, associated with economic assessment. It highlights the variety of instruments created for measuring quality of life according to this concept and considers health promotion as a crucial strategy to avoid medical reductionism and foster interdisciplinary dialogue. However, it argues that this proposal still needs refinement and testing in sanitary practices.This paper explores the relationships between quality of life and health by applying discourses from the health sector to other fields and disciplines.
