You get into bed meaning to check one message. Then there's a group chat to catch up on, a video that autoplays into another, and a news headline you have to read. When you finally look at the clock, it's well past the time you planned to sleep, and your alarm hasn't moved.
If that sounds familiar, you're far from alone. Scrolling before bed is a familiar habit for many people, and a surprisingly hard one to shake. This guide looks at why it happens, what the research actually says about phones and sleep, and how to build a realistic wind-down routine that doesn't require you to give up your phone altogether.
Why we keep scrolling when we should be sleeping
Late-night scrolling isn't simply a lack of willpower. A few things make it unusually sticky.
- There's no natural stopping point. Feeds refresh endlessly and the next video often starts on its own, so there's never a clear "end" that tells you to put the phone down.
- Night can feel like "me time". After a long day of work, family and commuting, scrolling can feel like the first moment that's truly yours. Researchers use the term bedtime procrastination for this pattern of delaying sleep even when nothing is stopping you from going to bed.
- Your brain stays switched on. Messages, comments and news invite a response. Sleep experts quoted in a Straits Times report shared by Singapore General Hospital note that how long you use your phone and how stimulating the content is both matter. They add that scrolling in bed can teach your brain to treat the bed as a place for entertainment rather than rest.
Understanding this helps, because the fix isn't to try harder. It's to make stopping easier.
How phone use before bed may affect sleep
Research on phones and sleep is still developing, and much of it shows associations rather than direct cause and effect. Even so, the overall picture is fairly consistent.
- It can push bedtime later. A 2025 survey of more than 45,000 students in higher education in Norway, published in Frontiers in Psychiatry, found that each extra hour of screen use after going to bed was linked to 59% higher odds of insomnia symptoms and about 24 minutes less sleep. The researchers couldn't show that screens caused these problems, but their findings suggest screen time may simply eat into time that would otherwise be spent sleeping.
- It may make it harder to fall asleep. The same Straits Times report points to studies linking bedtime device use with taking longer to fall asleep.
- Lost minutes add up. Expert guidance from the American Academy of Sleep Medicine and Sleep Research Society recommends that adults sleep at least seven hours on a regular basis. Scrolling that regularly pushes bedtime back can make that harder to reach.
Is blue light the only problem?
Blue light gets most of the attention, but it's probably only part of the story.
In a small, tightly controlled lab study published in 2014, adults who read on a light-emitting tablet for several hours before bed took nearly 10 minutes longer to fall asleep, had less REM sleep and felt less alert the next morning than when they read a printed book. That suggests evening light from screens can play a role.
However, a 2021 study of young adults found that turning on a phone's Night Shift mode did not lead to better sleep than using the phone normally. The researchers suggested that mental engagement, such as texting and scrolling, may matter more than the colour of the light.
In practice, three things seem to matter together:
- Time: minutes spent on the phone are minutes not spent sleeping.
- Stimulation: emotionally engaging content, chats and games keep your mind alert.
- Interruptions: notifications can pull you back in, or wake you up.
Night mode won't hurt, but it's unlikely to solve the problem on its own.
How to stop scrolling before bed without giving up your phone
You don't need a dramatic digital detox. Small changes that make the phone less convenient at night tend to be easier to stick with.
Change where the phone sleeps
Charging your phone outside the bedroom, or at least out of arm's reach, is one of the simplest changes you can make. If you rely on it as an alarm, a basic alarm clock can take over that job.
Let your phone go quiet automatically
Schedule Do Not Disturb or a sleep focus mode for the same time every night. Most phones let you allow calls from selected contacts, so family can still reach you in an emergency.
Swap the activity, not just the device
If you enjoy winding down with your phone, choose something calmer: a downloaded podcast, gentle music with the screen off, or an e-book with the brightness turned down. Save fast-moving social feeds, games and work chats for earlier in the evening.
Set a "last check" time
Pick a time to reply to any last messages, set your alarm and put the phone down. Telling family or colleagues that you won't reply after a certain hour can make this easier.
Start smaller than you think
If you usually scroll right up to the moment you fall asleep, aim for 10 or 15 phone-free minutes first, then build up. In a Singapore student campaign called "Phone Sleeps First", university students who took on challenges of three to seven nights reported cutting their late-night screen time by about 58 to 81 minutes. It was a student project based on self-reported results rather than a clinical trial, but it shows how short, specific goals can build momentum.
If you need your phone for work or family
Some late messages can't be avoided. If you need to stay reachable, keep the phone face down and on silent with only key contacts allowed through. Handle anything urgent, then put it away again rather than drifting back into the feed.
A simple 20ā30-minute night-time routine
There's no medically fixed length for a wind-down routine. Twenty to thirty minutes is a practical starting point, and public-health guidance such as the CDC's suggests turning off devices at least 30 minutes before bedtime. Adjust it to suit your evening.
| When | What to do |
|---|---|
| 30 minutes before bed | Reply to final messages, set your alarm, switch on Do Not Disturb and put the phone on charge, ideally outside the bedroom. |
| 25 minutes before | Dim the lights at home and do small tasks for tomorrow, such as packing your bag or laying out clothes. |
| 20 minutes before | Take a warm shower and do your skincare or other personal care. |
| 10 minutes before | Do something calm: read a printed book, write down tomorrow's to-do list, or try some light stretching or slow breathing. |
| Bedtime | Lights off. If your mind is busy, leave the phone where it is and focus on slow, steady breathing. |
The exact steps matter less than doing roughly the same thing at roughly the same time, so your body learns the cue. A sleep specialist quoted in another report shared by SGH also recommends keeping a consistent wake-up time, even on weekends, to help anchor your body clock.
Some nights you'll still end up scrolling. That's normal. Treat it as information about what made that evening harder, not as a reason to give up.
Make your bedroom more supportive of sleep
A good routine works best in a room that's set up for rest. The CDC recommends keeping the bedroom quiet, relaxing and at a cool temperature.
- Light: use soft, warm lighting in the evening, and block streetlights or early sunrise with curtains if they bother you.
- Temperature: Singapore nights are warm and humid, so a fan, air-conditioning set to a comfortable temperature and breathable bedding can all help. Our guide to the best cooling mattress in Singapore covers materials designed for airflow.
- Noise: a fan or white-noise machine can mask traffic or neighbours.
- Comfort: a mattress that suits your body and sleeping position makes it easier to settle once the phone is away. If you're unsure what feels right, our guide to firm vs soft mattresses is a useful starting point.

What if you still struggle to sleep?
Cutting back on late-night scrolling can help many people, but it isn't the answer to every sleep problem. It's worth speaking to a GP if:
- you regularly have trouble falling asleep, staying asleep or waking too early, and it affects how you feel or function during the day. SingHealth clinicians describe difficulties on at least three nights a week for at least three months as a pattern that warrants assessment;
- you or your partner notice loud snoring or gasping during sleep, or you feel very sleepy during the day despite spending enough time in bed;
- worry, low mood or stress is regularly keeping you awake.
A GP can talk through what might be affecting your sleep and, if needed, refer you to a sleep specialist.
Frequently asked questions
Is it bad to use your phone before bed?
Not necessarily, but long phone use after getting into bed has been linked to less sleep and more insomnia symptoms. Shorter, calmer use, with notifications silenced, is a reasonable middle ground.
How long before bed should I stop using my phone?
There's no single proven cut-off. Public-health guidance commonly suggests at least 30 minutes, and the researchers behind the Norwegian study suggest 30 to 60 minutes. If that feels like too much at first, start with 10 to 15 minutes and build up.
Does night mode or a blue light filter help?
It may reduce some light exposure, but one study found Night Shift mode didn't improve sleep compared with normal phone use. Reducing how long and how actively you use the phone is likely to matter more.
Is reading on my phone better than scrolling social media?
Calm, low-interaction activities are generally less stimulating than chats, games or fast-moving feeds. If you read on your phone, lower the brightness, silence notifications and set a time to stop.
Do I need a full digital detox?
No. For most people, small and consistent changes, such as charging the phone away from the bed and using Do Not Disturb, are more realistic than cutting out screens completely.
When should I see a doctor about poor sleep?
If sleep difficulties happen several nights a week over a period of months, affect your daytime life, or come with loud snoring or gasping, speak to a GP.
Sleep is a habit you can build
You don't have to overhaul your evenings overnight. Pick one change, such as charging your phone outside the bedroom or setting Do Not Disturb, and give it a week. Then add another.
And when you're ready to make your bedroom a more inviting place to switch off, visit an Englander gallery at Tai Seng or Tiong Bahru to try a mattress in person and find the comfort that suits you.
