Three changes, and none of them ask you to delete anything. Charge your phone outside the bedroom tonight. Switch your screen to greyscale. Make your worst app take four steps to open instead of one. Do those today and the pickups drop before you've had to decide anything bigger.
Three changes, in order
- **The phone sleeps in another room.** Buy a cheap alarm clock so you can't argue that you need it. If the bedroom is the only option, the phone goes face down across the room, on charge, off the bedside table.
- **Turn the colour off.** On an iPhone: Settings, Accessibility, Display & Text Size, Colour Filters, then Greyscale. Set Accessibility Shortcut to Colour Filters so a triple-click toggles it. On Android the path varies by manufacturer, usually under Digital Wellbeing or Accessibility.
- **Add four steps to the worst app.** Log out. Delete the saved password. Take the icon off the home screen. Use it in the browser instead. Four small obstacles at 11pm beat any amount of resolve.
Ten minutes. The rest of this page explains why those three.
Start with where the phone sleeps
Sleep is where the evidence is genuinely strong, so it goes first.
A meta-analysis of 20 studies covering 125,198 children found ["a strong and consistent association between bedtime media device use and inadequate sleep quantity (odds ratio [OR], 2.17; 95% CI, 1.42-3.32)"](https://pubmed.ncbi.nlm.nih.gov/27802500/). Then the finding that decides where you put the charger: ["children who had access to (but did not use) media devices at night were more likely to have inadequate sleep quantity (OR, 1.79; 95% CI, 1.39-2.31)"](https://pubmed.ncbi.nlm.nih.gov/27802500/).
Read that second one again. Not using it. Just having it within reach. Still worse sleep.
Two honest caveats. Those were children and adolescents, average age 14.5, so the numbers aren't yours exactly. And the pooled studies were cross-sectional, single snapshots that cannot tell you whether the phone wrecked the sleep or the bad sleep pulled out the phone. What it gives you is a cheap thing to test on yourself.
Greyscale, and what it does and doesn't do
A pre-registered field experiment with 112 people compared greyscale against setting time limits, and against just watching your own numbers. The friction won: greyscale ["led to an immediate, significant reduction of objectively measured screen time compared with the control condition"](https://pubmed.ncbi.nlm.nih.gov/36577008/), while the goal-setting group's use came down more slowly.
Now the half most articles leave out. The same authors wrote: ["In contrast to the popular belief that reducing screen time has broad benefits, we found no immediate causal effect of reducing usage on subjective well-being and academic performance."](https://pubmed.ncbi.nlm.nih.gov/36577008/)
So greyscale buys back time. It doesn't hand you a better mood, and if you expect one, you'll switch the colour back on inside a week and decide you're beyond help. You're not. You got given hours, and hours you can spend.
Friction beats willpower
The strongest causal result available here comes from a month-long randomised controlled trial that used an app to block all mobile internet on people's phones for two weeks. The result: ["The intervention 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/)
What filled the gap matters too. The authors found that ["when people did not have access to mobile internet, they spent more time socializing in person, exercising, and being in nature"](https://pubmed.ncbi.nlm.nih.gov/39967678/).
Look closely at the design, because it's the useful part. Texts still worked. Calls still worked. Desktop internet still worked. Nobody went off the grid. What changed was that the phone stopped being the shortest path to a feed, which is what step three does on a smaller scale.
If you want the phone to hold that line rather than relying on yourself at 11pm, [Shield](/shield) is the part of Renovyn that puts real blocks between you and an app. A screen time passcode a friend sets and keeps does a similar job for nothing.
Not sure any of this applies to you? [Work out whether your use is actually a problem](/guides/social_media/is-my-social-media-use-a-problem) first.
What nobody has actually tested
Plenty of popular advice has no trial behind it that we could find. Batching notifications to arrive twice a day. One offline day a week. Buying a flip phone. Consumer blocking apps as products in their own right.
That doesn't mean they don't work. People report all of them helping, and the mechanism is the same friction the blocking trial used. It means nobody has run the study, so treat them as worth trying rather than proven.
What this is, and what it isn't
There's no recognised diagnosis of social media addiction. The American Psychiatric Association says the proposed gaming condition ["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 behavioral addiction (as opposed to chemical substance use disorders) identified in DSM-5-TR"](https://www.psychiatry.org/patients-families/internet-gaming).
You'll also read that the feed causes depression. All four UK Chief Medical Officers looked and wrote that ["This research does not present evidence of a causal relationship between screen-based activities and mental health problems"](https://www.gov.uk/government/publications/uk-cmo-commentary-on-screen-time-and-social-media-map-of-reviews), and that ["it could be, for example, that CYP who already have mental health problems are more likely to spend more time on social media"](https://www.gov.uk/government/publications/uk-cmo-commentary-on-screen-time-and-social-media-map-of-reviews). They still recommend a precautionary approach, and so do we.
The size of the link is small. An analysis of three datasets covering 355,358 people found the association ["negative but small, explaining at most 0.4% of the variation in well-being"](https://pubmed.ncbi.nlm.nih.gov/30944443/).
None of that makes your evening any less lost. It means the honest claim is narrower than the headlines. The hours are real, the sleep finding is well documented, and the rest is contested.
For the mechanism, [why the feed is built to hold you](/guides/social_media/why-the-feed-is-built-to-hold-you) covers what the design is doing and where that argument runs out.
Where to get support
Internet and Technology Addicts Anonymous covers this explicitly. Their opening line names ["social media addiction, phone addiction, video addiction, television addiction, gaming addiction, news addiction..."](https://internetaddictsanonymous.org/), and their meetings are free and open to anyone who struggles with compulsive internet use. Most are online and daily. In the UK there are in-person meetings in London and Oxford.
[SMART Recovery UK](https://smartrecovery.org.uk/faqs/) runs free groups built on cognitive behavioural methods, with no religious content and no higher power required. Their FAQ names gambling, food, shopping and gaming rather than social media, so expect to be the one in the room with a slightly different problem. That's usually fine.
The NHS has no service for this. Its general explainer lists internet use among the things people become addicted to, then offers treatment directories for alcohol, drugs and smoking. If what's underneath the scrolling is darker than boredom, Samaritans is on 116 123, free, any hour.
Common questions
**Has TikTok ruined my attention span?** The blocking trial found that removing mobile internet improved objectively measured sustained attention, which is the closest thing to an answer anyone has. Nothing in it proves permanent damage. Two weeks of less access moved the measure, which is a reason for hope.
**Am I addicted to social media?** There's no diagnosis to qualify for, so the label won't help you either way. More useful: is it taking time you meant for something else, have you tried to cut down and not managed it, and do you feel worse after a session. Yes to those is reason enough to change something.
**How do I stop boredom scrolling specifically?** Boredom scrolling needs a replacement, because the hand reaches before you've decided anything. Keep something physical within arm's reach of wherever you scroll. [What to do with your hands instead](/guides/social_media/what-to-do-with-your-hands-instead-of-scrolling) has options that survive a real evening.
**Does a digital detox actually work?** A [meta-analysis of 10 studies](https://pubmed.ncbi.nlm.nih.gov/39280291/) found a significant effect on depression (standardised mean difference -0.29), and none on life satisfaction, stress or overall mental wellbeing. A break may lift low mood. It probably won't do the rest of what people hope for.
**I put the phone down and feel worse. Is that normal?** Very. The first few evenings after you add friction feel flat and slightly irritable, and people mistake that for proof it isn't working. Give it a week, and plan what fills the gap.
