How to stop scrolling before bed. I've typed that into Google more times than I'd like to admit, usually at midnight, on my phone, in bed. The irony wasn't lost on me.
Around 91% of UK adults use screens before bed. A UK cross-sectional study of young adults found that those who used their phone within 30 minutes of trying to sleep had double the risk of developing problematic smartphone use compared to those who stopped an hour before. In the US, 38% of adults say their pre-bed phone habit makes their sleep noticeably worse — and there's no reason to think the UK is much different. You probably already know this. The problem isn't information — it's that knowing you should stop doesn't make stopping any easier.
I tried a lot of the standard advice. Some of it worked, some didn't. Here are the eight things that actually stuck.
1. Charge your phone outside the bedroom
This is the single most effective thing I did, and the one I resisted the longest. If your phone isn't within arm's reach, you can't scroll. That's it. No willpower required. The phone is in the hallway, plugged into a charging station, and the temptation is physically removed.
A bedside charging dock or phone station in another room costs under a tenner on Amazon. It sounds like a small purchase but it changes the dynamic completely. Your phone goes on the charger when you start getting ready for bed, and it stays there.
The objection everyone raises: "But I use my phone as my alarm." Right. About that.
2. Get an alarm clock that isn't your phone
Your phone being your alarm clock is the single biggest excuse for keeping it beside your bed. It's also the reason you check it the moment you wake up, and the reason you're still scrolling at midnight. Break that link and a lot of the problem solves itself.
A basic analogue alarm clock costs a few quid. If you want something that actually helps your sleep rather than just waking you up, a sunrise alarm clock gradually increases light over 20-30 minutes before your alarm time, simulating dawn. Your body starts producing cortisol naturally, so you wake up lighter instead of being jolted awake. I switched to one about six months ago and the mornings are genuinely different.
3. Switch your phone to greyscale after 8pm
This one genuinely surprised me. A study published in The Social Science Journal found that students who switched their phones to greyscale cut daily screen time by an average of 38 minutes. A separate 2023 study in Computers in Human Behavior Reports found similar results — about 20 minutes less daily screen time, plus reductions in problematic use and improvements in sleep quality.
The reason it works: social media is designed around colour. Bright notification badges, colourful thumbnails, vibrant images. Remove the colour and everything looks a bit dull. Your brain gets less reward from each scroll, so you scroll less. It's not dramatic — you don't suddenly hate your phone. You just find it slightly less interesting, and that's enough to make putting it down easier.
On iPhone, you can automate this with a Shortcut that activates greyscale at a set time. On Android, it's in the Digital Wellbeing settings. Set it for 8pm and you won't have to think about it.
4. Use app timers for the worst offenders
Screen Time on iPhone and Digital Wellbeing on Android both let you set daily time limits per app. When the timer runs out, the app locks with a grey screen. You can override it, but having to actively tap "Ignore Limit" adds just enough friction to make you pause and think about what you're doing.
I set 30-minute evening limits on Instagram, Twitter, and Reddit. The first week I overrode them constantly. By week three, I mostly didn't bother. The friction works — not perfectly, not every time, but enough.
5. Replace the scroll with a book
The reason scrolling is hard to stop isn't just habit. It's that lying in bed with nothing to do feels boring, and your brain wants stimulation. You need to replace the dopamine source, not just remove it.
A physical book works for most people. Not a Kindle (still a screen), not an audiobook on your phone (still your phone). An actual book. If your partner is asleep and you don't want the main light on, a clip-on book light solves that for under a tenner.
Reading before bed has its own sleep research behind it. A 2009 University of Sussex study found that just six minutes of reading reduced stress levels by 68%, more than listening to music or going for a walk. The content matters too — something absorbing but not adrenaline-fuelled. Novels work. Thrillers work less well. Twitter arguments work not at all.
6. Make your bedroom boring on purpose
If your bedroom has a TV, a tablet on the nightstand, and a laptop on the floor, you've created an entertainment centre with a bed in it. Your brain associates the room with screens and stimulation rather than sleep.
Sleep researchers call this stimulus control: your bedroom should be associated with sleep (and sex) and nothing else. That sounds extreme, but even small changes help. Move the TV to the living room. Charge the tablet elsewhere. The fewer screens in the room, the less tempted you are.
If noise is the issue — you're used to falling asleep with the TV on — a white noise machine or decent earplugs handle that without a screen.
7. Try blue light glasses if you won't ditch screens entirely
Some evenings you're going to use screens. That's realistic. If you're watching a film with your partner or finishing something for work, amber blue light glasses worn for the last two hours of the evening can reduce the melatonin suppression from screen light.
They're not a substitute for actually putting the phone down. Wearing amber glasses while doom-scrolling is still doom-scrolling — your brain is still processing emotionally charged content and staying alert. But for passive screen use like watching a film, they help with the light side of the equation while you work on the habit side separately. We've tested the best blue light blocking glasses separately if you want specific picks.
8. Set a specific wind-down time, not just a bedtime
"I'll stop scrolling at 10:30" is vague and easy to push back. "At 9:30, I put my phone on the charger in the hallway and start my wind-down" is specific and tied to an action. The difference matters.
A wind-down routine gives you something to do instead of scrolling. It doesn't have to be elaborate — a cup of decaf tea, a chapter of a book, getting tomorrow's clothes out. The point is that it's a defined sequence that signals to your brain that the day is ending. We've put together a full wind-down routine if you want something structured to follow.
Why willpower fails: screen time and sleep habits
I spent about three months telling myself I'd stop scrolling at 10pm. I'd still be on my phone at 11:30, every night, feeling annoyed at myself. The problem isn't willpower. It's that your phone in your hand, in a dark room, when you're bored, is almost impossible to resist. The cue (boredom), the routine (scroll), and the reward (distraction) are all right there, within arm's reach, and your tired brain will take the path of least resistance every single time.
That's why the tactics above all focus on changing the environment rather than fighting yourself. Phone in another room. Greyscale making everything dull. A book already on the pillow. You don't need iron discipline to stop using your phone at night. You just need to make the lazy option something other than scrolling.
How to stop scrolling before bed: frequently asked questions
How long before bed should I stop using my phone?
The American Academy of Sleep Medicine recommends 30-60 minutes. A UK study found that using your phone within 30 minutes of trying to sleep doubled the risk of problematic use patterns. Two hours is ideal for melatonin recovery, but even 30 minutes makes a measurable difference. Start where you can and extend it over time.
Does greyscale mode actually reduce phone use?
Yes. Multiple studies show it cuts daily screen time by 20-38 minutes on average. It's most effective for social media and general browsing — less so for video content, which is still stimulating in black and white. Set it to activate automatically in the evening so you don't have to remember.
Is it the blue light or the content that keeps me awake?
Both, but the content probably matters more than you think. Research from The Conversation (2025) found that emotionally charged social media content keeps your brain in a heightened state of alertness, independent of screen light. Blue light suppresses melatonin, but the mental stimulation from scrolling is often the bigger sleep disruptor.
What should I do instead of scrolling before bed?
Read a physical book — a 2009 University of Sussex study found just six minutes of reading reduced stress by 68%. Other options: journaling, stretching, listening to a podcast with a sleep timer, or a breathing exercise. The key is that it doesn't require a screen and isn't mentally overstimulating.
