What is health?
Health is not just absence of disease but a state of overall wellbeing.
In 1948, the World Health Organization (WHO) defined health with a phrase that is still used today.
“Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” WHO, 1948.
In 1986, the WHO further clarified that health is:
“A resource for everyday life, not the objective of living. Health is a positive concept emphasizing social and personal resources, as well as physical capacities.”
This means that health is a resource to support an individual’s function in wider society. A healthful lifestyle provides the means to lead a full life.
More recently, researchers have definedhealth as the ability of a body to adapt to new threats and infirmities. They base this on the idea that modern science has dramatically increased human awareness of diseases and how they work in the last few decades.
