Clinophilia is a psychological and medical term derived from the Greek words clino (to lie down) and philia (love or affinity). It describes a condition where an individual has an excessive or pathological desire to remain in bed for extended periods, often for days at a time, without necessarily being asleep. While it is not a standalone "disease" in the DSM, it is considered a significant clinical symptom of several underlying mental health conditions, most notably severe clinical depression, chronic fatigue syndrome, or certain stages of schizophrenia. Clinophilia differs from simple laziness or "staying in" on a weekend; it is characterized by a "lack of vitality" or an inability to find the motivation to enter the vertical world. In the elderly, it can also be a sign of "psychomotor regression." Treatment typically focuses on the primary diagnosis, involving a combination of cognitive-behavioral therapy (CBT) and medication to help the individual regain their "élan vital" and re-engage with daily life activities outside of the bedroom.
