What the guides say

The short version of each, before you read it.

How do you do a dopamine detox? A version that holds up

  • A dopamine detox is a planned break from one or two compulsive cues, usually phone apps. It does not drain or reset dopamine.
  • Dopamine responds most to rewards that are better than expected, which is why unpredictable feeds are so hard to put down.
  • In a 2025 trial, two weeks of blocked mobile internet cut screen time from about 314 to 161 minutes a day and improved attention and wellbeing.
  • Only about a quarter of participants kept the block on most days, so start small and use a blocker rather than willpower.

The four happy chemicals, explained without the hype

  • Dopamine tracks wanting and anticipation more than pleasure, which is why cues and progress pull so hard.
  • About 90 percent of serotonin lives in the gut; no food or checklist item reliably dials brain serotonin.
  • Oxytocin follows affectionate contact with people and animals you are close to.
  • Exercise of twenty minutes or more is the most reliable mood action on the list, via endorphins and endocannabinoids.
