The standard answer to how long before bed you should stop using your phone is 30 to 60 minutes. The [American Academy of Sleep Medicine](https://aasm.org/americans-are-doomscrolling-at-bedtime-prioritizing-screen-time-over-sleep/) says to avoid handheld screens for 30 to 60 minutes before bed, and the [National Sleep Foundation](https://www.thensf.org/screen-use-disrupts-precious-sleep-time/) says at least an hour. Those are reasonable targets. When researchers looked at the gap directly in 2026, though, its exact length mattered less than how long people scrolled and whether the phone came back during the night.

Most adults are nowhere near an hour anyway. In one study of more than 1,200 students, the typical gap between the last screen and bed was 5 to 10 minutes. So if you want one change that is likely to help, move the phone out of the bed and out of the night, and treat the countdown as a bonus.

## 41% of Americans say their phone costs them sleep

In a survey of 9,750 US adults run in May and June 2026, [Pew Research Center](https://www.pewresearch.org/short-reads/2026/09/01/about-half-of-americans-say-they-spend-too-much-time-on-their-smartphone/) found 41% say their smartphone hurts how much sleep they get. Only 5% say it helps, and 46% say it makes no difference. Pew called sleep the clearest perceived downside of everything it asked about.

**62%**: of US adults aged 18 to 29 say their smartphone hurts how much sleep they get, compared with 14% of those 65 and older ([Pew Research Center, September 2026](https://www.pewresearch.org/short-reads/2026/09/01/about-half-of-americans-say-they-spend-too-much-time-on-their-smartphone/))

The number drops steadily with age: 52% of people in their 30s and 40s, 36% of those 50 to 64. These are people's own impressions, not measured sleep. Still, they line up with an [AASM survey](https://aasm.org/americans-are-doomscrolling-at-bedtime-prioritizing-screen-time-over-sleep/) in which 38% of adults said reading news on a phone before bed makes their sleep worse (46% of 18 to 24 year olds). I covered the broader question of [whether scrolling before bed affects sleep](https://ivehadit.app/blog/scrolling-phone-before-bed-affect-sleep) in an earlier post, so this one sticks to the gap.

## Where the 30 to 60 minute rule comes from

Screens are thought to hurt sleep in three ways. They push bedtime later because one more video is always available. They keep your brain alert when it should be winding down. And their light can delay melatonin, the hormone that tells your body it's night.

The light effect is real in the lab. In one [PNAS study](https://doi.org/10.1073/pnas.1418490112), reading on a light-emitting e-reader for hours before bed delayed melatonin and sleep compared with a printed book. For a phone, the effect is probably modest, and staying alert or staying up later likely matters more. The 30 and 60 minute figures are sensible round numbers built on these mechanisms. No study has shown that 45 minutes fails and 60 succeeds.

## How long before bed should you stop using your phone, according to 2026 research

The most direct adult data comes from a [Frontiers in Psychiatry study](https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2026.1735186/full) of 1,262 medical students in Germany, Austria, Hungary and Japan, surveyed in 2024. Between 96% and 98% used a screen in the last hour before bed. The median was 30 minutes of screen use, ending about 10 minutes before bed in Europe and 5 minutes in Japan.

**5 to 10 minutes**: median gap between the last screen and bedtime among 1,262 medical students in four countries ([Liebig et al., Frontiers in Psychiatry, 2026](https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2026.1735186/full))

### Minutes of scrolling mattered more than when you stopped

After adjusting for other factors, the total time spent on screens before bed had a small but significant link to poor sleep, mostly because people took longer to fall asleep. The length of the gap itself was not significantly linked. The authors point out a likely reason: almost nobody had a long gap, so there was little to compare.

Treat this as a hint, not a verdict. The study is a snapshot, so it can't show cause and effect. Only 13% to 37% of invited students responded, the night-time screen questions were new, and medical students are not typical adults.

### Larger adult datasets point the same way

In 122,058 US adults, daily screen use before bed was linked to a 33% higher prevalence of poor sleep quality than no screen use ([JAMA Network Open](https://doi.org/10.1001/jamanetworkopen.2025.2493)). A conference abstract using National Sleep Foundation data found that smartphone use in the hour before bed went with worse sleep quality ([SLEEP 2024](https://doi.org/10.1093/sleep/zsae067.01111)), though an abstract is modest evidence. Neither tested a specific cut-off.

### For kids, the gap itself seems to count

A new [Frontiers in Sleep study](https://www.frontiersin.org/journals/sleep/articles/10.3389/frsle.2026.1783027/full) of preschoolers measured the time between the TV going off and bedtime. When the TV ended mattered more for sleep duration than total TV time, and even modest increases in the screen-free gap were linked to longer sleep. If you're working out rules for older children, my post on [what time teens should stop using their phone](https://ivehadit.app/blog/what-time-teens-stop-using-phone) goes through that separately.

## The phone does more harm once it comes back into the night

The strongest links in the [student study](https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2026.1735186/full) had nothing to do with the evening. Using a screen after waking up at night was tied to roughly 1.7 to 1.8 times the odds of poor sleep. Being woken by a device was tied to about 1.5 to 2.4 times the odds, depending on how often it happened.

About 1 in 4 European students used a screen at least weekly after waking in the night. If that sounds familiar, my post on [checking your phone in the middle of the night](https://ivehadit.app/blog/check-your-phone-middle-of-the-night) covers it in more depth. The practical point is that a phone on the nightstand affects both the hour before sleep and the hours during it.

There is a little intervention evidence too. A sunrise-alarm programme for medical students that included taking devices out of the bedroom reduced late-evening screen time and improved sleep and mood ([BMC Medical Education](https://doi.org/10.1186/s12909-020-02263-6)). It was a small, brief study, so it supports the idea without settling it.

## Some people who scroll every night sleep fine

A survey of more than 1,000 Canadian adults, published in Sleep Health and reported by [Medical Xpress](https://medicalxpress.com/news/2025-11-night-bed.html), found close to half used screens at bedtime every night. Their overall sleep health was about the same as people who never did. Nightly users even reported the best sleep timing and daytime alertness.

The worst sleep showed up in people who used screens more than once a week but not every night. One possible reading is that a consistent routine matters, though this survey can't prove it. What it does suggest is that if you scroll nightly and feel rested, you don't need to panic. Test it on yourself before you trust a rule.

## A practical answer: start at 30 minutes and test the rest

Start with 30 minutes, the low end of the AASM range, and work toward 60 if it feels good. Any real gap beats the typical 5 to 10 minutes. Shrinking how long you scroll counts as well, even if your last glance still lands close to bedtime.

> **Move the charger before you set a timer** Charge your phone outside the bedroom and use a cheap alarm clock. Then schedule Do Not Disturb or a Sleep Focus so nothing can buzz you awake. This removes the pre-bed scroll and the night-time checking in one move, which is where the clearest risk sits.

Plan for willpower to give out. According to [Pew](https://www.pewresearch.org/short-reads/2026/09/01/about-half-of-americans-say-they-spend-too-much-time-on-their-smartphone/), 45% of Americans tried to cut back on their phone in the past year, and only 25% of them say it went extremely or very well. A charging spot in the hallway works at midnight, when your resolve doesn't.

1. Week one, change nothing: Each morning, jot down when you put the phone down, roughly how long it took to fall asleep, and how you felt on waking.
2. Week two, move the phone out: Charge it outside the bedroom, use a regular alarm, and stop scrolling at least 30 minutes before lights out.
3. Skip the news feed at night: If you want headlines, read one summary earlier in the evening instead of scrolling them in bed.
4. Compare the two weeks: If you fell asleep faster or woke up sharper, keep the setup and try stretching the gap toward an hour.
5. Accept a null result: If nothing changed, you may be one of the people who sleep fine with a screen, and that's a fair outcome.

If you want a screen in the evening, the Frontiers authors suggest that passively watching a TV across the room may be gentler than a phone held close to your face. That's their opinion and hasn't been tested, but it's an easy swap to try during week two.

If your late-night scrolling happens on a laptop, I built I've had it to close social media feeds in the browser while leaving the rest of the internet open, so there's less to fall into at 11 p.m. ([How it works](https://ivehadit.app/start))

- The 30 to 60 minute advice is a reasonable target, but no study has found an exact threshold.
- Most people leave a gap of only 5 to 10 minutes, so any real gap is an improvement.
- Total scrolling time before bed and night-time phone use showed clearer links to poor sleep than the gap length.
- Charging the phone outside the bedroom tackles the evening scroll and night-time waking together.
- Some nightly scrollers sleep fine, so a two-week self-test tells you more than a rule.

## Questions people ask

### Is 30 minutes without screens before bed enough?

Thirty minutes is the low end of the American Academy of Sleep Medicine's 30 to 60 minute range, and it's far more than most people manage. No study shows that 30 minutes fails where 60 succeeds, so it's a good starting point.

### Is the one-hour no-screens rule backed by science?

The National Sleep Foundation recommends at least an hour, and screen use before bed is consistently linked to worse sleep. But a 2026 study of 1,262 students found the length of the gap was not independently linked to sleep quality, partly because almost nobody had a long one.

### Should I keep my phone out of the bedroom?

It's probably the most useful single change. Using a phone after waking at night and being woken by it had the strongest links to poor sleep in 2026 research, and a phone in another room prevents both.

### Is watching TV before bed better than using my phone?

The authors of a 2026 Frontiers in Psychiatry study suggest that passively watching a distant TV may be gentler than a phone held close. That's their opinion and hasn't been tested directly.

### I scroll every night and sleep fine. Is it still bad?

Maybe not. A Canadian survey of more than 1,000 adults found nightly screen users slept about as well as non-users, though it was correlational, so a two-week self-test is a better guide than guilt.
