There is no single standard duration because this is a behavioral strategy, not a medication course. In practice, common formats include 24 hours, 48–72 hours, and 7 days. A 24-hour reset is powerful for awareness and identifying triggers. A 48–72-hour window can be more effective for breaking compulsive stimulation loops. A 7-day approach supports deeper habit redesign, but if it is too restrictive, it may reduce adherence. The smartest model is to start short, then build weekly low-stimulation blocks or a “reduced-screen day” routine. That turns dopamine detox from a one-time event into long-term system optimization.
