Sigh. We're all doing it. At some point, getting into bed and reaching for the phone became as automatic as pulling up the covers.
A quick scroll through Instagram, a few YouTube clips, maybe a peek at the news. And suddenly it's an hour later. What started as a way to wind down has quietly become one of the most researched sleep disruptors of our time.
So let's actually get into why it's so hard to stop scrolling before bed, what it's doing to your sleep, and what can help in getting rid of this habit.
How Common Is Bedtime Scrolling?
A survey by Amerisleep found that 86% of Americans use their phone in bed before falling asleep, spending an average of 38 minutes scrolling each night. That number might not sound alarming on its own, but over the course of a year it adds up to roughly 231 hours.
For most people, this isn't something they think about or consciously choose to do each night. It has simply become part of the routine.
While it’s true that Gen Z spends the most time scrolling in bed, with an average of 50 minutes, older generations are not far behind, with millennials at around 37 minutes, Gen X about 35, and baby boomers roughly 33.
Across every age, the phone has become part of the bedtime ritual in a way that nothing else ever has.
The Relationship Between Scrolling and Sleep Quality
Knowing that nearly everyone does it is one thing, but understanding what it actually does to your sleep is another. Let’s talk about it.
A large study of over 45,000 Norwegian university students found that each additional hour of screen use in bed raised the odds of insomnia symptoms by 59% and reduced total sleep time by roughly 24 minutes per night.
The pattern holds across older populations as well. A 2025 study published in JAMA Network Open, one of the largest of its kind covering over 122,000 participants, showed the same connection: regular screen use before bed leads to shorter sleep duration and worse overall sleep quality.
What these studies point to isn't just a correlation between phones and bad sleep. It's a dose-response relationship, meaning the more time spent on a screen in bed, the worse the outcomes tend to be.
Why Scrolling is Bad for Your Sleep
It tells your brain it's still daytime
The screens on our phones emit what's known as blue light, which refers to short wavelengths that fall between 400 and 500 nanometers on the visible light spectrum. These wavelengths are particularly effective at suppressing melatonin, the hormone your body releases to signal that it's time for sleep.
Harvard researchers compared the effects of blue light and green light on melatonin suppression and found that blue light suppressed the hormone for about twice as long and shifted the body's internal clock by twice as much.
Even relatively brief evening exposure to screen light can delay the onset of melatonin release, which pushes your sleep window later and makes it harder to fall asleep at a natural hour.
Your brain gets wired up right when it needs to wind down
Every time you come across something new while scrolling, your brain releases a small hit of dopamine, which is the same reward chemical involved in gambling, eating, and other pleasurable behaviors.
Social media platforms are designed with this in mind: the unpredictability of what comes next on a feed is precisely what makes it so hard to stop.
Research in neuroscience has shown that the brain's reward circuitry responds to variable rewards more strongly than to predictable ones, which is why an endless feed of mixed-quality content can hold your attention longer than something you actually enjoy.
By the time you put the phone down, your nervous system is far more activated than it was when you picked it up.
It chips away at your deep sleep
The cumulative effect of blue light exposure and cognitive stimulation before bed affects the quality of what happens after.
Research has found that pre-bedtime exposure to light from electronic devices is associated with reduced REM sleep, the stage most involved in emotional processing and memory consolidation. It's also linked to decreases in slow-wave sleep, the deepest and most physically restorative phase of the sleep cycle.
The content itself is a problem
The American Academy of Sleep Medicine has specifically highlighted that emotionally charged or stressful content, like news cycles, heated comment sections, and upsetting videos, keeps the mind in a state of alert even after the phone goes down.
When your brain is still processing something that triggered anxiety, frustration, or even just mild curiosity, the transition into restful sleep becomes significantly harder.
That’s because the nervous system doesn't have an off switch you can press; it needs time and the right conditions to settle. Handing it stimulating content right before bed is the opposite of that.
How to Stop Scrolling Before Bed
Here's the thing that doesn't get said enough: this is genuinely difficult to change. For a lot of people, bedtime scrolling is a ritual with real emotional weight attached to it.
It might be the only quiet time you get to yourself all day. It might be how you decompress, how you feel connected to people, or how you avoid lying in silence with thoughts you'd rather not sit with.
BJ Fogg, a behavioral scientist at Stanford who studies habit formation, describes behavior as the product of three things coming together at once: motivation, ability, and a cue. If you remove any one of those three, the behavior stops.
That framing is useful here because it means you don't have to rely entirely on willpower. You can change the conditions instead:
Acknowledge it honestly: Before anything changes, it helps to be clear-eyed about how much you're actually on your phone at night and what's driving it. Is it boredom? Anxiety? A need for connection? The habit of it? Tracking your screen time for a week (most phones make this easy) can be a surprisingly confronting first step, and an effective one.
Start small, not strict: Going from 90 minutes of bedtime scrolling to none overnight is likely to fail and feel punishing.
A more sustainable approach is to set a modest target: maybe 30 minutes earlier than your current cutoff, then push it back further over the following weeks. Small wins build the forward momentum that makes harder changes feel possible.
Put physical distance between you and your phone: This is one of the simplest interventions you can do and all it takes is leaving your phone in another room before bed. When the phone isn't within arm's reach, the automatic reach-and-scroll behavior has nowhere to go. The cue is gone.
Make your phone more boring: Switch your display to grayscale, move social apps off your home screen, and turn off any notifications you don't actually need.
Replace, don't just remove: The phone isn't just filling time before sleep. It's meeting a need. If that need is decompression, try something that works with your nervous system instead of against it: a physical book, a quiet podcast, a short stretch, a bath.
If it's connection, consider calling or texting someone earlier in the evening so you're not relying on a feed to feel in touch.
A Better Way to Sleep
Even if you follow every step in this article and genuinely cut back on bedtime scrolling, there will be nights where sleep still doesn't come easily.
Some nights, despite your best efforts, you'll lie awake longer than you'd like, move through lighter sleep than you need, or wake up feeling like the night didn't do much for you.
That's where Kimba comes in, not as a replacement for the habits above, but as something that works in the background while you sleep.
Kimba is a smart diffuser that connects to wearables you may already own, like Oura, Apple Watch, WHOOP, Garmin, or any tracker synced through Apple Health. While you sleep, it reads your biometric data in real time: heart rate, HRV, movement, and sleep stage.
When those signals show that your body is struggling to settle or drifting out of deeper sleep, Kimba responds with a short, quiet pulse of scent designed to support your nervous system back toward rest.
The scent blends Kimba uses are 100% natural and clinically tested, formulated specifically to work with the limbic system, the part of the brain that regulates sleep, stress, and emotional balance.
If you're working on scrolling less before bed, Kimba won't replace that effort. But on the nights where the effort isn't quite enough, it gives your body a better chance of getting the sleep it needs anyway.
