What happens to the core meaning of 'unhealthy' when its use extends figuratively to relational dynamics?

Answer

The core meaning remains intact as injurious to well-being, only the domain shifts

When the designation of 'unhealthy' is applied to non-physical domains, such as a relationship characterized by emotional strain or habits inhibiting personal growth, the fundamental essence of the term persists. The shift occurs in the domain of application—moving from the corporeal realm to the psychological or social realm—but the core meaning remains consistent: the situation or behavior is detrimental and injurious to the individual’s overall state of well-being. It signifies a condition incompatible with long-term thriving, whether that thriving is physical or emotional.
