Off the HookDigital detox, without the cold turkey.
What a digital detox and a "dopamine detox" can and can't do, according to the research, and a slower version that lasts.
A digital detox is a break from your phone or social media, to use it less afterwards. The evidence favours cutting back over quitting: restricting social media gives a small boost to well-being, while a short complete break showed no lasting change in mood. A "dopamine detox" doesn't lower your dopamine; its creator meant limiting a habit to set times and removing its cues. The detox that works is slower: about one hour less a day, the most addictive parts removed, kept up for around ten weeks.
Three things to stop believing.
MythA dopamine detox resets your dopamine.
Dopamine isn't a tank that empties when you scroll and refills when you sit in a dark room. Avoiding stimulation doesn't lower it.
The psychiatrist who popularised "dopamine fasting", Cameron Sepah, meant stimulus control: limit a problem habit to set times and remove what triggers it. He called the dopamine name a metaphor. The useful half is the habit part.
MythA week offline will make you happier.
A 2025 review of complete breaks from social media (10 studies, 4,674 people) found no significant change in mood or life satisfaction.
Cutting back did better. Across 32 randomized trials, restricting social media gave a small boost to well-being, and quitting completely was no better than limiting it.
MythIt takes 21 days to break a habit.
The 21 days come from a 1960 self-help book. When researchers measured it, a new habit took a median of 66 days to feel automatic, ranging from 18 to 254.
Missing a single day didn't set people back. Plan for about two months, and don't restart the count after a bad evening.

less phone time a day, four months after using it one hour less a day for a week.
Brailovskaia et al., 2022. 619 people. The cut-back group kept its gains longer than the group that quit for a week.A detox that takes ten weeks.
About the time a habit needs. Three phases, each asking a little more.
Weaning offWeeks 1 and 2
Remove the bottomless parts first: Reels, Explore, For You. Keep messages and friends, so you're not cut off. Expect the urge to scroll to be strongest now.
BuildingWeeks 3 to 6
Fill the time on purpose. Pick one thing for the evenings you got back, and give it a fixed slot. Boredom in this phase is a sign it's working.
New normalWeeks 7 to 10
Keep what works and notice what triggers a relapse, like stressful days. A missed day doesn't undo anything; coming back does the work.
After ten weeks, Off the Hook moves on to chapters of four to six weeks, chosen with Lumi: grow a habit, start a new one, or pick up a new interest.
If you want a weekend offline anyway.
It can be a good reset. These four steps make it more than a pause.
Tell the people who'd worry.
A message to the group chats saves you from checking "just in case".
Plan what fills the time.
In a 2025 study, the gains came with more time with people, exercise and outdoors.
Keep calls and texts.
Blocking mobile internet, not the whole phone, was enough for 91% to improve in that study.
Decide what comes back.
Bring back the people, not the feed. That's where most detoxes undo themselves.
Questions
Does a dopamine detox work?
Not the way the name suggests. Avoiding stimulation doesn't lower or reset your dopamine. The psychiatrist who popularised it, Cameron Sepah, meant a behavioural technique: limit a problem habit to set times and remove its cues. That part has good support.
Does a digital detox improve mental health?
Cutting back helps a little. A 2025 meta-analysis of 32 randomized trials found a small improvement in well-being from restricting social media. A separate review of complete breaks found no significant change in mood or life satisfaction.
How long should a digital detox be?
Longer than a week, and gentler than all or nothing. New habits took a median of 66 days to become automatic in one study, and people who cut their phone use by an hour a day kept most of it four months later.
What should I do during a digital detox?
Plan what fills the time before you start: a book, a walk, people. The gains in a 2025 study came with more in-person time, exercise and time outdoors, not from the absence of the phone alone.
Should I get a dumbphone instead?
Maybe, if you can live without maps, banking apps and WhatsApp on a flip phone. Most people only want to lose a few apps. See dumbphone, or keep your iPhone and lose the feed.
