What is Wellness?
The terms “health” and “wellness” are often used interchangeably. The World Health Organization has defined health as, “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” Although wellness can be defined similarly, some suggest that wellness is more active and process-oriented whereas health is more of a state of being. For example, the national wellness institute defines wellness as, “an active process through which people become aware of, and make choices toward, a more successful existence.”
What does wellness mean?
Although we’ve just defined wellness, what people mean when they say wellness is slightly different. Within the wellness field, we tend to think of wellness as somewhere between physical health and mental well-being. Usually when people are referring to “health”, they mean physical health, and when people say “well-being”, they are referring to mental health. Wellness is a somewhat broader term that generally includes both physical health and mental well-being as well as other dimensions like spirituality.
