What you've heard: A dopamine fast resets your brain
Does a dopamine detox actually work?
The name misreads the science, and the behavior can help. Take a month off something that has stopped feeling like a choice, and skip the day-long fasts. Evidence grade: Emerging.

The evidence
The idea is that a day or more without pleasures, such as phones, treats and music, lets your dopamine "reset". Dopamine is not a tank that drains and refills; it is a learning and wanting signal that responds to surprising rewards and the cues that predict them. A recent review of dopamine fasting reports no trials. One addiction psychiatrist advises thirty days away from a substance or behavior that has become compulsive, and that is clinical advice, not a trial result.13 A deliberate break can still help, because it interrupts the cue-and-habit loop and shows you what the habit was doing for you.
