This document discusses health, wellness, and holistic health from multiple perspectives. It defines health as a state of complete physical, mental, and social well-being according to the WHO. Wellness is described as an active process of awareness and decision-making for a balanced life. Models of wellness, such as Travis' continuum of wellness and Ardell's three domain model, show how wellness impacts health and longevity. A holistic perspective recognizes that physical, mental, social, environmental, and lifestyle factors all determine an individual's health status.
