What does unhealthiness mean?
Unhealthiness is an uncountable noun naming the state or condition of being unhealthy. It is most often used of a person, body, place, environment, or system whose condition is detrimental to physical health. Typical examples include the unhealthiness of cramped housing, an unsafe workplace, or a poor diet. The word focuses on a condition as a whole rather than on one particular symptom or diagnosis, giving it a formal or evaluative tone in medical and public-health writing while remaining ordinary in general prose. Unhealthiness is related to the older noun health and to healthy through the standard English prefix un- and suffix -ness. Compared with illness, which more often names an individual's disease or bout of ill health, unhealthiness can describe a broader and continuing condition. That distinction makes it especially useful when discussing patterns, places, and environments rather than isolated cases.

Unhealthiness does not name one disease; it names the whole condition of poor health.
