Key distinction
Loneliness is subjective; social isolation is objective. Either can hurt health — but they respond to different strategies.
- Life transition (move, breakup, job change)
- No recurring shared activity (everything is “ad hoc”)
- Social anxiety / avoidance loop
- Depression (can feel like loneliness)
- Schedule two touchpoints (call/walk/meal).
- Choose one recurring group activity (weekly).
- Do one “useful” act (help someone; volunteer; contribute).
Use: Social Health Plan.
Red flags
If loneliness comes with persistent depressed mood, hopelessness, or suicidal thoughts, seek mental health support.
