If you are reading this, you have probably noticed that your child's screen time has crept past what feels right, and that the arguments about it are getting worse. That is a common place to be, and it says nothing bad about your parenting.
A detox for children looks different from one for adults. Children have less say over their environment, they are still building the skills a detox is meant to protect, and the whole thing goes better when it is done with them rather than to them.
What does a digital detox for kids actually involve?
A set period where recreational screens are off or sharply limited, with something real put in their place. That is all. It does not need to be total, and it does not need to be long.
The version most families can sustain is narrower than the one they first imagine. Pick the screens that cause the most trouble (often social media, short video or games) and the times that matter most (often bedtime and school nights). Leave homework, calls to family and anything needed for school alone.
One honest limit: the trial I can point to is in adults, not children. Castelo and colleagues (2025, PNAS Nexus) randomly assigned 467 participants to have mobile internet blocked on their smartphones for two weeks. It improved sustained attention, mental health and subjective well-being. Calls and texts still worked, and more nightly sleep was one of the mechanisms.
That suggests a block can help, and that a partial block is a reasonable design. It does not prove the same size of effect for a nine-year-old or a fifteen-year-old.

Where should you start?
With sleep. There is a research link between screen time and sleep, and bedtime is a part of a child's day that screens can easily eat into.
A 2025 meta-analysis in Frontiers in Psychiatry pooled 21 cohort studies covering 548,338 people. Each extra hour of daily screen time was associated with a bedtime about 13.2 minutes later, roughly 3 to 5 minutes less sleep, and higher odds of difficulty falling asleep. That is an association, not proof of cause, and it is a general screen-time finding rather than one specific to children.

For a sense of the target, the American Academy of Sleep Medicine consensus recommends 9 to 12 hours per 24 hours for ages 6 to 12, and 8 to 10 hours for ages 13 to 18. Regularly sleeping those amounts is associated with better attention, behaviour and learning.

In practice, that means devices charge outside the bedroom, and screens stop a set time before bed. It is a small change with a plausible payoff, and it is far easier to hold than a full ban.
Does it matter what the screen is?
Probably, though the evidence in children is thin, so hold it loosely.
In a randomised experiment with 60 four-year-olds, nine minutes of a fast-paced cartoon led to worse immediate performance on executive-function tasks than an educational cartoon or drawing. The effect was immediate and possibly temporary, and it was one small study.

Older findings are more mixed. A well-known study linked more daily TV at ages 1 and 3 with attention problems at age 7, but a reanalysis of the same dataset found the link appeared, if at all, only at very high viewing levels and vanished after adding two covariates. That one is contested.

A larger cohort of 2,441 children found that more screen time at 24 and 36 months was associated with poorer developmental screening scores later, with small effects, based on parent reports.

The fair reading is that the evidence points in a consistent direction without being dramatic. That is a reason to be calm and steady about it, not alarmed.
What should replace the screen?
Something specific, and ideally something you do together.
Research on children's executive functions, including staying focused, found that activities such as aerobics, martial arts, yoga, mindfulness, non-computer games and some school curricula can help. The programs that worked involved repeated practice with gradually increasing challenge, and children with weaker executive functions benefited most.

You do not need a program. The takeaway is that regular, slightly challenging, hands-on activity is a sound thing to swap in. A football practice, a board game night, a bike ride, a drawing project.
Choose it before the detox starts. An empty evening with nothing planned is where the argument about the phone usually restarts.
How do you get a teenager on board?
Do it with them. This is advice, not a finding, but it is consistent with something the research does show: changing intentions produces smaller changes in behaviour (Webb & Sheeran's meta-analysis). So it may not be enough to persuade a teenager that screens are bad.
Source: Webb & Sheeran, Psychological Bulletin, 2006.
My advice is to change the setting and share the rules:
- Include yourself. If the phone basket applies to everyone at the table, it is a household rule rather than a judgement about them.
- Ask what they would trade. Letting a teenager choose which two hours to protect may make them more likely to keep to it.
- Keep the channel to friends open. For many teens, the phone is where their friendships happen. Cutting that off entirely turns the detox into social isolation, which is a different problem.
- Run it as a trial. Two weeks, then talk about how it went. Castelo used two weeks, and it is a short enough stretch to agree to.
Expect irritation in the first few days. That is normal and it usually passes.
Do digital detox camps and retreats for teens work?
They can be a good option, though I cannot point to research that tests them, so treat any claim of guaranteed results with caution.
There is a sound reason they might help. In a study of popcorn habits, people who habitually ate popcorn at the cinema ate stale popcorn as readily as fresh, but did not in a meeting room. Habits are driven by context cues, and a new place removes many of them.
Source: Neal, Wood, Wu & Kurlander, Personality and Social Psychology Bulletin, 2011.
A summer camp or retreat takes a teenager out of the room where the scrolling happens. That may help, though it is my inference rather than something camps have been shown to do. The harder part is the return, because the old cues are waiting at home.
If you are considering one, ask:
- Is the break voluntary, or something they feel has been done to them?
- What is the plan for the first week back?
- Is there real activity on offer, such as sport, outdoors, making things, or time with other people?
A camp is not required. A weekend away or even a changed routine at home are other ways to change the setting, though I cannot point to research on how well they work.
What if it goes badly?
Then you have learned something, and that is allowed. A rough first few days is expected. Missed days do not cancel the attempt.
If a child seems unusually distressed, withdrawn or unable to function without a device, speak to your GP or a school counsellor. A detox is a household habit change, not a treatment.
For your own phone, if you want help with the same pull, Boredom is an app built for that. It is a side note here, since the main work is the family agreement.
The short version
Start small, begin with sleep, choose the replacement before you start, and agree the rules together. Gentle, steady limits are the approach I would suggest, and sleep is where the research link is most relevant to act on.
Keep it to two weeks, check in, and adjust. That is a plan a child can actually live with.
