What is the definition of health according to the World Health Organization?

The World Health Organization defines health as a state of complete physical, mental, and social well-being, not merely the absence of disease or infirmity. This comprehensive definition emphasizes that health is not just about physical capabilities or the absence of illness; it encompasses emotional and social well-being as well.

This holistic view recognizes that various factors such as mental health, social connections, and even societal and environmental influences contribute to an individual's health status. Hence, an individual can be considered truly healthy only when they are thriving in all these dimensions. This broad definition aligns with the goals of public health to promote overall well-being and quality of life, rather than simply focusing on treating diseases.

In contrast, other definitions, such as a lack of disease or disability, narrow the concept of health to just the absence of medical conditions rather than a broader and more comprehensive state of well-being. Wellness in environmental conditions and access to healthcare services are important aspects of health; however, they do not encompass the full scope of what health represents according to WHO standards.
