Summary
Minw explores the psychology behind “內耗” (internal depletion/rumination) — a commonly used Chinese term for the exhausting cycle of chronic self-criticism and negative thinking. The article distinguishes rumination (反芻, a physiological response) from anxiety, explaining the neurobiological pathway: stressor → cortisol/amygdala activation → prefrontal cortex diverted to threat-scanning → failure to return to baseline when the stressor persists only in thought. Escape strategies are discussed.
Minw 探討「內耗」背後的心理學——慢性自我批評與負面思維的消耗性循環。文章區分反芻（生理反應）與焦慮，解釋神經生物學路徑：壓力源 → 皮質醇/杏仁核激活 → 前額葉皮質轉向威脅掃描 → 壓力源僅存在思維中時無法回歸基線狀態。
Key Points
- Rumination (反芻) is the natural mechanism that gets stuck: the brain treats imagined/past stressors as ongoing threats
- Stress response: cortisol → amygdala activates → prefrontal cortex redirects to threat-scanning
- The body doesn’t require a real stressor to trigger stress responses, or for it to end to return to baseline
- Rumination amplifies self-denial; chronic anxiety creates a vicious cycle (内耗 = chronic anxiety + rumination loop)
- Avoidance and suppression worsen rumination; behavioral activation and cognitive restructuring help
Insights
The key neurobiological insight is that the human brain cannot easily distinguish between real and imagined threats — a memory of a stressor activates the same cortisol/amygdala pathway as the original event. This makes rumination a feature of a threat-monitoring system that evolved for physical dangers, but one that misfires for social/cognitive threats which don’t resolve physically. The framing of rumination as a “natural physiological response” (not a personal failure) reduces the self-blame that would otherwise worsen the loop.

Raw Excerpt
人不需要因為真實壓力源也能產生壓力反應；更有趣的是，人也不用因為真實壓力源結束就調節到平常狀態。而這，正是反芻（Rumination）的開端。
