When you notice yourself endlessly replaying a distressing memory, do something hands‑on instead

Cost: No cost at all. The hard part is first recognizing that you’re stuck in this loop – a skill that takes practice.
In plain terms: Endlessly dwelling on the same bad memory won’t yield any answers. It only deepens depression, cements negative thoughts, makes it harder to solve problems or take action, and can drive away friends who’d otherwise listen. As soon as you realize you’re stuck in this cycle, get busy with a physical task.
Benefit: A review of multiple studies shows that repetitive rumination on distressing events worsens depression. This pattern, known as rumination, also strengthens negative thinking and weakens problem‑solving abilities. It hampers real‑world action and can alienate supportive people. It is linked to anxiety, binge eating, alcohol misuse, and self‑harm.

Notes: This is the hardest item in this section to quantify; the review only provides general direction. “Doing something else” reflects the author’s own approach. The literature supports one core idea: diverting attention is better than staying trapped in rumination. No research has compared which specific activities work best.
