“Wellness” sounds like a modern marketing word, but versions of the term have appeared in English for centuries. What changed most dramatically was not its existence, but the range of meanings attached to it.
An old word with a relatively quiet history
Early uses of “wellness” broadly referred to the state of being well. It would be too neat to say that the word once had one objective medical definition opposed to “illness”; historical usage was less standardised than that.
Twentieth-century health promotion expanded the idea
In the twentieth century, writers and health promoters increasingly used wellness to describe something more active than the absence of disease. Halbert L. Dunn’s idea of “high-level wellness” is frequently cited in histories of the modern movement, although today’s wellness culture emerged from many influences rather than one person or theory.
From health concept to commercial category
Fitness, nutrition, spa services, mindfulness, workplace programmes, digital products and consumer health brands have all adopted the term. This breadth is one reason “wellness” can be useful in ordinary language but imprecise in medical reporting.
A product labelled “wellness” is not necessarily evidence-based, clinically effective or medically necessary. Likewise, everyday activities that make someone feel restored should not automatically be described as treatments.
Why language matters in a health publication
London Health Journal uses wellness as a broad cultural and lifestyle category, not as a diagnosis or guarantee of benefit. Clinical claims should still be supported by appropriate evidence and distinguished from personal preference, commercial language and general wellbeing.
The history of the word is therefore also a history of expanding expectations: from being well, to actively pursuing health, to a large marketplace that now sits partly inside and partly outside medicine.
