Put the phone in another room with the volume up. Set a timer, or just look at a clock. Do one ordinary thing for ten minutes: wash up, make tea, tidy one surface. That is the whole exercise. The uncomfortable part arrives in the first two or three minutes and then flattens, and the point of doing it deliberately is to find that out on an evening when nothing is at stake.
The exercise, exactly
- **Next room, not out of the house.** Kitchen, hall, anywhere with a wall between you. Keep the ringer on so a real call still reaches you.
- **Ten minutes.** Longer is not braver. Ten is short enough that you will actually start.
- **One ordinary task with your hands.** Washing up is ideal. It has an end, it needs hands and it does not need attention.
- **Do not check the time constantly.** If clock-watching takes over, put a timer on in the other room where you can hear it.
- **Notice what you reach for.** Your hand will go to a pocket that is empty. That is the thing you came to observe.
Then do it again tomorrow. A week of ten minutes teaches you more than one heroic afternoon, and it does not blow up your day if it goes badly.
What the ten minutes usually does
No trial has measured a ten minute separation, so what follows is what people consistently describe rather than a finding.
The first thirty seconds are fine. Then something that feels like being slightly on alert arrives, and with it a specific thought: what if someone needs me. Around minute three it is at its loudest, and it is at exactly that point that most people go and get the phone, which teaches them that the feeling was unbearable, when what they actually proved is that it was interruptible.
If you stay in the room, the alertness usually flattens somewhere in the middle. Not gone. Quieter, and less interesting than it was. By minute eight most people have forgotten the exercise is happening, which is the result you are looking for.
Getting the phone at minute four is not a failure either. Note the time you gave in, go again tomorrow, and see whether it moves. Numbers moving is the evidence.
The fear is not irrational, so separate it
Being told your anxiety is silly does not help, partly because some of it is correct.
The phone is genuinely your alarm, your bank, your maps, your two-factor codes, and the number the school rings. It is also how an ill parent reaches you at ten at night. Ten minutes with the ringer on does not touch any of that, and saying so explicitly is what makes the exercise possible.
So split it into two lists. **Real** consequences: a call you would have to take, a delivery, a person genuinely waiting on you tonight. **Felt** consequences: everything else, which is mostly the sense that something is accumulating while you are not looking.
The real list is handled by keeping the phone in the house and audible. The felt list is what the ten minutes is for.
If you are on call, or a carer, or a parent of a young child, do this differently rather than not at all. Set a focus mode that allows calls from a named list of people through, and put the phone in the next room with the volume up. The point is distance, not being unreachable.
The trial that got the design right
The strongest evidence in this whole area was built on exactly that distinction. Researchers blocked all mobile internet on people's phones for two weeks while ["allowing participants to maintain mobile connection (through texts and calls) and nonmobile access to the internet"](https://pubmed.ncbi.nlm.nih.gov/39967678/). The result: it ["improved mental health, subjective well-being, and objectively measured ability to sustain attention; 91% of participants improved on at least one of these outcomes"](https://pubmed.ncbi.nlm.nih.gov/39967678/).
Nobody went off grid. The friction went on the feed, not on the people. Your ten minutes is a very small version of that same shape, and it is why the instruction is "next room, ringer on" rather than "leave it at home and be brave".
Building it up
Once ten minutes is dull, which usually takes a week or so, extend it in one of three directions.
**Longer at home.** Thirty minutes, then an evening hour. The phone stays in the hall, still audible.
**Out of the house, short.** A walk to the shop without it. This is the one that surprises people most, because the world turns out to be navigable.
**Overnight.** The phone charges in another room and a cheap alarm clock does the waking. This is the version with actual evidence attached: a review of 20 studies covering 125,198 children found ["a strong and consistent association between bedtime media device use and inadequate sleep quantity"](https://pubmed.ncbi.nlm.nih.gov/27802500/), and children who had access to a device at night without using it still slept worse. Cross-sectional, and about children, so an association rather than proof, but it is the cheapest experiment on this page.
Pick one. Doing all three in the same week is the classic way to be back where you started by Sunday. [What the first week of a quieter phone feels like](/guides/phone_screen/the-first-week-of-a-quieter-phone) covers the stretch after that.
Nobody is going to call this a disorder
Worth saying, because people arrive at this frightened by what they have read about themselves.
There is no recognised condition here. The American Psychiatric Association states that its proposed research condition for gaming ["is limited to gaming and does not include problems with general use of the internet, online gambling, or use of social media or smartphones"](https://www.psychiatry.org/patients-families/internet-gaming), and that gambling disorder is the only behavioural addiction in the current manual.
That cuts both ways, usefully. There is no label to earn, so you do not have to qualify before taking this seriously. And feeling twitchy without your phone is not a symptom of anything with a name, it is what happens when something you check a hundred times a day is suddenly two rooms away.
There is a line, though. If being without the phone produces real physical panic, racing heart, tight chest, a sense of dread that does not lift when you have it back, that is worth taking to a GP, because that pattern usually belongs to anxiety rather than to a device. In the UK, if it is heavier than that, Samaritans is on 116 123 at any hour.
Why this exercise is worth ten minutes a day
Every practical change in this area assumes you can tolerate a gap. Charging the phone in the hall assumes it. Notifications off assumes it. Any block or limit assumes it. If the gap itself is intolerable, all of them get undone in the first week and it looks like a discipline failure when it was actually a tolerance one.
Ten minutes a day builds the thing the rest depends on, which is why it comes before the settings. When you are ready for those, [the four changes with the most evidence behind them](/guides/phone_screen/how-to-stop-picking-up-your-phone) are next.
And if some of the alertness is really about people being annoyed with you for replying slowly, that is a separate problem with a separate fix: [say it once, to the right people](/guides/phone_screen/telling-people-youre-slower-to-reply).
Common questions
**Why do I feel anxious when my phone is in another room?** Because checking has become the way you resolve small uncertainties, and removing it leaves those uncertainties sitting there for a few minutes. It is uncomfortable rather than dangerous, and it usually flattens within a few minutes if you stay put.
**Is phone separation anxiety a real condition?** Not a recognised one. There is no diagnosis for smartphone use anywhere in the current manuals. That does not make the feeling imaginary, and it does mean you should judge it by what it costs you rather than by whether it qualifies as something.
**What if something important happens while I am away from it?** Keep the phone in the house with the ringer on, and allow calls from a named list through. Ten minutes at that distance changes nothing about your reachability, which is precisely why it is a fair test of the feeling rather than of the risk.
**How long until it stops feeling like this?** Most people find ten minutes unremarkable within a week of daily practice. Longer gaps take longer. If nothing shifts at all after a fortnight, that is worth mentioning to a GP rather than pushing harder.
