The Canadian Health Network, part of the Public Health Agency of Canada, uses the World Health Organization’s (WHO) widely used and generally accepted definition of health:
“a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.”

But check this out, the Canadian Health Network goes on to clarify what this definition really means, that health is:
Multidimensional : it is related to physical, mental and social well-being.
Multi-determined : it is affected by many factors, including:
- spiritual beliefs and practices
- social support
- relationships
- peace
- justice
|
- the economy
- income
- the environment
- policies
- citizen participation in decision making.
|
|
|
Dynamic : it shifts freely and frequently.
Subjective : each person’s experiences of health can differ widely, even when the “dimensions” appear to be similar.
This definition has been criticized for its lack of boundaries - I guess it’d be difficult to know where to start treatment when there so many possibilities (controllable and uncontrollable).
However, the old definition of health was real loosey-goosey with: “an absence of illness”. This makes total sense when you consider the current state of healthcare – the healthcare system was set up way-back when this definition was accepted.
What do you think would happen if Canada’s healthcare system began changing its policies and practices to include this new definition of health?
