This document discusses different concepts of health, including the biomedical concept which views health as the absence of disease, the ecological concept which sees health as adaptation to the environment, and the holistic concept which recognizes social, economic, and political influences. It also describes the health-illness continuum model, which illustrates well-being as more than just an absence of illness, showing how one can move either toward higher wellness or premature death based on factors like awareness, education, and lifestyle choices. The model compares treatment-focused and wellness-focused approaches.
