How to stop using your phone in bed and scrolling at night

To stop using your phone in bed, charge it outside the bedroom. That one move did more for me than any app, night mode or resolution, because it removes the cue instead of asking you to resist it at the hour you are least able to. Then fill the gap it leaves: a cheap alarm clock, a paper book by the bed, and a set time when screens stop.

That is what worked for me, and it is the change I would make first if I were starting again. Here is what the research says, and then the steps in order.

What the phone in bed does to sleep#

The evidence is mostly surveys, so it shows links rather than proof, but the links point one way.

In a survey of 844 adults in Belgium, six in ten took their phone into the bedroom. Texting or calling after lights out went with worse sleep and taking longer to fall asleep, and phone use at bedtime went with more insomnia, more fatigue and getting up later.

A much larger survey of 45,202 university students in Norway found that each extra hour on a screen after getting into bed went with 59 percent higher odds of insomnia symptoms and 24 minutes less sleep. The link was the same whether the hour went to social media or to anything else.

One small trial points the same way. Thirty-eight university students in China were randomly assigned either to stop using their phones in the 30 minutes before bed, for four weeks, or to carry on as usual. The group that stopped fell asleep faster, slept longer, reported better sleep and less arousal at bedtime, and did better on a memory task.

Reviewers of this research list four ways screens can harm sleep: the light, the arousal of whatever you are doing, being woken by the phone in the night, and plain displacement, where an hour on the phone is an hour not asleep. They also note that it runs both ways. People who are not sleeping well reach for the phone to fill the time or to settle themselves, which makes the phone in bed a habit that feeds itself.

Blue light is the smaller part#

Most advice about phones and sleep is about blue light, and the light is real. In a lab study, twelve young adults read for about four hours before bed on a light-emitting e-reader, or from a printed book, for five evenings each. With the e-reader they took nearly ten minutes longer to fall asleep, made less melatonin in the evening, and their body clocks shifted later.

But when researchers test the fixes people actually use, they find little. In a week-long trial with 167 young adults, sleep was no better with the iPhone's Night Shift on than with it off. Across the whole group, even the people asked to put the phone away for the hour before bed did not sleep measurably better; only in a follow-up look at those already sleeping close to seven hours did the no-phone group come out ahead. And a Cochrane review found it is not known whether blue-light filtering glasses improve sleep at all.

The trials are small and do not all agree, so hold this loosely. My reading of it: the light matters at the margins, and a warm-tinted screen at midnight is still a phone at midnight. The bigger costs are the ones the surveys and the small trial keep pointing to: the time it takes, and the way what is on it keeps you up. So the fix is about where the phone is, not what color it glows.

The steps that worked for me#

Charge it outside the bedroom#

Not on silent on the nightstand. Outside, somewhere you have to get up and walk to. Sleep medicine uses the same principle for insomnia, called stimulus control: the bed is kept for sleep and sex and nothing else, so the room stops cueing wakefulness. Lesson five is built around this one move.

Buy a separate alarm clock#

"I need it as my alarm" is how the phone gets back into the room. A basic alarm clock removes the reason.

Give the last hour a different job#

Decide the time when screens stop, and decide what that hour holds instead: a paper book, a shower, a conversation, tomorrow's list written by hand. An empty hour is where the phone gets picked back up. Researchers have a name for staying up later than you meant to when nothing is making you: bedtime procrastination. In one survey it went with not getting enough sleep. An hour with a job in it is easier to end on time than an empty one.

Get up if you cannot sleep#

This is part of the same insomnia guidance: if you are lying awake, get out of bed, and go back when you feel sleepy. Do not reach for the phone to pass the time. That is how the room learns to mean scrolling.

Add friction to what is left#

For the hours when the phone is still with you, make the worst of it harder. Delete the apps that pull you in at night, set app limits, log out of the accounts, turn the screen gray in the evening, and put a filter on content you are trying to stop. The blockers page shows how, device by device. I have no good study to point to for most of these tricks; treat them as things to try, and keep the ones that work for you.

Try a month without it in the room#

Cal Newport's Digital Minimalism makes a case I found useful. Instead of trimming phone use bit by bit, take a month away from the optional apps and sites, use the month to get back in touch with what you actually value, and then add back only what serves it, with rules about when and how. More than 1,600 people signed up for the experiment he ran while writing the book.

You can apply the same idea to the bedroom alone: thirty nights with the phone outside the door, and then decide what, if anything, has earned its way back.

Why this matters more if you are stopping pornography#

For anyone trying to stop pornography, the phone in bed is the cue that matters most, because it puts the easiest supply there is in your hand at the hour you are most tired and most alone. When I finally wrote my cues down, nearly all of them happened in one room, at one hour, with one object in my hand. Moving that object out removed more of them than everything else combined.

Tiredness is a cue in its own right, so the sleep you get back helps twice. How to sleep better covers the rest of the night.

Questions people ask#

Does night mode or a blue-light filter help?#

Not much, on current evidence. In a trial that tested Night Shift directly, sleep was no better with it on, and a Cochrane review could not say whether blue-light glasses help sleep at all.

How long before bed should I stop using my phone?#

In the small trial above, 30 minutes was enough to make a difference. I would start with an hour, because the hour before sleep is where my habit lived.

What if I need my phone at night for emergencies?#

Leave it charging just outside the door with the ringer on, or set do not disturb to let calls from chosen contacts through. You will still hear it if it matters.

Is reading on a phone in bed as bad as scrolling?#

The reading is not the problem so much as what sits one tap away from it. In the lab study above, even the light of an e-reader delayed sleep a little. A paper book gives you the reading without the light or the pull.

If you want to make this the first move of something larger, the thirty days puts it in the very first evening: filters on every device, and the phone charging outside the bedroom from the first night.
