In non-physical contexts, what core meaning of "unhealthy" remains intact when describing relationship dynamics?

Answer

Injurious to well-being

The figurative extension of the term 'unhealthy' to contexts like relationships or finance demonstrates that the core concept of detriment remains constant even when the domain shifts away from the purely corporeal. When a relationship is described as unhealthy due to constant criticism or emotional strain, it is detrimental to mental and emotional stability, thereby indirectly affecting overall well-being. Thus, the underlying meaning—that the condition or behavior is injurious to the individual’s state of well-being—is retained, regardless of whether the harm is physical or psychological.
