Doomscrolling is not weak willpower — it is your threat-detection system hijacked by infinite feeds. The amygdala and related circuits scan for danger; algorithms serve outrage, disaster, and comparison on repeat. You leave the screen more alert and more exhausted.
What happens in the brain
- Threat scanning — bad news keeps the amygdala engaged
- Stress hormones — cortisol and adrenaline rise; sleep prep fails
- Dopamine anticipation — next swipe might bring relief or shock
- Prefrontal fatigue — impulse control weakens late at night
- Body state — racing heart, tight chest, shallow breathing

3-step behavioral interrupt
- 1. Name it — “This is doomscrolling, not information I need now.”
- 2. Change state — stand, cold water, 60-second walk, box breathing
- 3. Replace cue — podcast chapter, paper book, or scheduled worry time tomorrow
