Research Shows Phone Use Before Bed Increases Insomnia Risk by Over 50% and How to Fix It

If your smartphone sits right next to you on the nightstand (or even under your pillow) every night, you're in good company. About 90% of people use electronic devices within an hour of bedtime, and many keep their phones within arm's reach while they sleep. After all, staying connected and never truly logging off is what makes technology so convenient, right?
Well, not exactly. Your evening phone habits might be affecting your sleep and overall health in ways you haven't considered. While that quick scroll through social media or check of your messages seems harmless enough, it can actually have a bigger impact on your sleep than you might think.
Does Using Your Phone Before Bed Really Affect Sleep?
Yes, using your phone too much close to bedtime can definitely affect your sleep.
What seems like an innocent habit, crawling into bed and opening up your phone for "just a few minutes," can actually have a significant impact on how well you sleep and how you feel the next day.
One study involving over 45,000 young adults found that each hour of evening screen time increased insomnia risk by 59% and reduced sleep by an average of 24 minutes per night.
The researchers looked at different activities like scrolling social media, watching videos, gaming, and reading on devices to see how they affected sleep.
But here's the thing: it's not just that you're using your phone that disrupts sleep. The type of activity you're doing makes a big difference.
Research indicates that more passive phone use – such as listening to music or a calming podcast – doesn't have the same negative effect on sleep compared to active engagement. Active use includes things like texting, scrolling social media, reading emotionally charged content, or responding to work emails.

How Your Phone Disrupts Your Sleep
Smartphones are designed to capture and hold our attention, but when it comes to bedtime, this can work against us. Here's what happens when you use your phone before bed.
It Keeps Your Brain Active and Alert
When it's time to wind down for sleep, your brain needs the opposite of stimulation – it needs calm. Using your phone does the exact opposite by keeping your mind engaged and alert.
Even a quick check of messages or social media can activate your brain and delay the natural transition to sleep. Your mind can stay revved up long after you've put the phone down, as you continue thinking about what you saw or read.
This mental stimulation is particularly strong with interactive content. Responding to messages, commenting on posts, or engaging with apps keeps your brain in an active state when it should be preparing for sleep.
The Blue Light Factor
Phone screens emit blue light, an artificial light that closely mimics natural daylight. During the day, this can actually be helpful by making you feel more alert and focused. But at night, blue light sends the wrong signal to your brain.
Your body's internal clock called the circadian rhythm, relies on light cues to know when it's time to be awake and when it's time to sleep. Blue light exposure in the evening can confuse this system by making your brain think it's still daytime.
Research has found that blue light can suppress melatonin production for up to 3 hours after exposure. Melatonin is the hormone that makes you feel drowsy and helps regulate your sleep-wake cycle. When melatonin levels are suppressed, you may find it harder to feel sleepy at your normal bedtime.
However, the evidence shows that this effect is most pronounced in people who use screens for extended periods – typically 2 hours or more – right before bed. Brief checks or minimal use may have less impact, though individual sensitivity can vary.
Content Can Trigger Strong Emotions
Going to sleep should be a peaceful experience, but engaging with your phone too close to bedtime can work against this. Whether you're scrolling through news, social media feeds, or even work emails, you might encounter content that triggers strong emotional responses.
Seeing something stressful, upsetting, or even exciting right before bed can leave you feeling wired and wide awake. Stress and anxiety are two of the most common causes of sleep problems, and evening screen use can be a significant source of both.
Even positive emotions can interfere with sleep. That funny video or exciting news might leave you feeling energized when you should be feeling calm and drowsy.

How Long Before Bed Should You Stop Using Your Phone?
There's no universal rule that works for everyone, but research provides some helpful guidelines.
Most sleep specialists suggest putting devices away 1-2 hours before your intended bedtime. This gives your brain time to naturally wind down and your melatonin levels to start rising.
If going phone-free for two hours feels unrealistic, start smaller. Even putting your phone away 30 minutes before bed can make a noticeable difference for many people.
-
For heavy users (2+ hours of evening screen time): Consider stopping screen use 2 hours before bed to allow for adequate mental wind-down time.
-
For light users (brief checks or minimal use): Stopping 30-60 minutes before bed may be sufficient, though longer is generally better.
-
For sensitive individuals: Those who are particularly affected by light or stimulation may benefit from longer screen-free periods before sleep.
The key is finding what works for your sleep patterns and lifestyle. Some people can use their phones up to 30 minutes before bed without issues, while others need a full 2-hour buffer to sleep well.
Tips for Better Sleep at Night
You don't have to completely eliminate your phone from your evening routine. Small changes can make a big difference in how well you sleep.
Create Phone-Free Boundaries
-
Establish a digital cutoff time: Choose a specific time each evening to put your phone away, and stick to it consistently. Start with 30-60 minutes before bed if longer periods feel too challenging.
-
Keep phones out of the bedroom: This removes the temptation to scroll when you should be sleeping. Use a traditional alarm clock instead of your phone's alarm.
-
Create a charging station outside the bedroom: Set up a designated spot in another room where you can charge devices overnight.
Use Your Phone's Built-In Features
-
Activate night mode: Most phones have settings that reduce blue light emission after sunset. While these don't eliminate all sleep disruption, they can help minimize the impact.
-
Set "Do Not Disturb" schedules: Program your phone to automatically silence notifications during your designated sleep hours.
-
Use app timers: Many phones offer features that track and limit your usage of specific apps during evening hours.
Replace Phone Time with Sleep-Friendly Activities
-
Try relaxing alternatives: Instead of scrolling, consider reading a physical book, doing gentle stretches, or practicing deep breathing exercises.
-
Prepare for tomorrow: Use the time you'd normally spend on your phone to lay out clothes, write a to-do list, or do other preparation that can help you feel more organized.
-
Create a calming environment: Dim the lights, play soft music, or try aromatherapy to signal to your body that it's time to wind down.
What to Do If You're Still Having Trouble Sleeping
If you've reduced your evening phone use and created a better bedtime routine but still struggle with sleep after 2-3 weeks, it might be time to look at other factors or consider talking to a healthcare provider.
Sometimes, even with good phone habits, it can be challenging to transition from the day's mental activity to a calm, sleepy state. This is especially true if you've been dealing with stress, have an irregular schedule, or are naturally more sensitive to light.
Some people find a gentle, natural sleep aid helpful during this transition. Sip2Sleep® offers a melatonin-free option with natural ingredients that work with your body's sleep-wake cycle to help ease the shift from wakefulness to sleep, without the grogginess that can come with other sleep aids.
The sublingual delivery allows for quick absorption when you need help winding down, making it a useful addition to your bedtime routine alongside good sleep hygiene.
When to Seek Professional Help
Consider talking to a healthcare provider if you experience:
-
Chronic insomnia lasting more than a month
-
Excessive daytime sleepiness despite adequate time in bed
-
Sleep problems that interfere with your work or relationships
-
Difficulty staying awake during important daytime activities
