How Doomscrolling Before Bed Affects Your Sleep

Key takeaways:

• More than one-third of U.S. adults say doomscrolling before bed makes their sleep worse.

• Blue light combined with emotionally charged content disrupts your body's ability to wind down.

• Poor sleep weakens self-control, which makes the scrolling habit harder to break.

• A consistent screen-free bedtime routine, along with a natural sleep aid, can help restore sleep quality.

You've probably told yourself "five more minutes" while scrolling in bed, only to realize it's already past midnight and too late to get a full night's sleep. But those extra minutes aren't just cutting into your sleep time. They may be changing how well you sleep for the rest of the night.

A 2025 survey from the American Academy of Sleep Medicine (AASM) found that 38% of U.S. adults say scrolling through news and current events before bed makes their sleep slightly or significantly worse.

Among younger adults aged 18 to 24, that number rises to 46%. Half of all adults report using a screen while in bed every day, and more than one-quarter say they prioritize screen time over getting the recommended amount of sleep.

What are brain rot and doomscrolling?

Doomscrolling refers to the compulsive habit of scrolling through negative or emotionally charged content online, often without a clear reason to keep going. The behavior became widespread during the COVID-19 pandemic and has remained common since.

While brain rot is a relatively new term, it is closely associated with doomscrolling. Oxford University Press named it the Word of the Year in 2024 and defined it as "the supposed deterioration of a person's mental or intellectual state, especially viewed as the result of overconsumption of material considered to be trivial or unchallenging." 

It's not a clinical diagnosis, but research has found that excessive digital content consumption can weaken attention and memory over time.

Both habits share a common thread: passive, prolonged screen use that tends to leave people feeling worse rather than better. And for many people, that screen use is happening right before sleep.

Why does doomscrolling before bed make it harder to sleep?

When you consume emotionally stimulating content close to bedtime, your brain stays in a heightened state known as presleep cognitive arousal. Rather than transitioning toward rest, it continues processing what you've seen — distressing headlines, social comparisons, or fast-moving video content.

"Internalizing topics that are stressful or worrisome before bed makes it difficult to have the deep, restorative sleep that is imperative to overall health," said Dr. James Rowley, past president of the American Academy of Sleep Medicine, in the same survey. "Phone use before bed should be limited altogether, but it's important to also be mindful of the type of content you view near bedtime."

Social media platforms are also designed to keep you engaged. Content that triggers small dopamine rewards creates a loop that makes it hard to stop scrolling, even when you know it's past your bedtime. The fear of missing out adds to the problem by creating pressure to keep checking for new posts or updates.

One study of 830 young adults found that emotional investment in social media predicted sleep problems more strongly than total screen time. It wasn't how long people scrolled that mattered most. It was how the content made them feel.

Does the type of content matter more than blue light?

Blue light from screens does suppress melatonin production, which can delay sleep onset. Research shows that two or more hours of evening screen time can significantly disrupt the melatonin surge your body needs to fall asleep.

But blue light is not the only factor that makes scrolling before bed so disruptive to sleep. Dr. Rowley noted that "blue light, especially when combined with emotionally charged content, can trick our body clocks into a state of daytime-level alertness, disrupting the circadian rhythm and making it more difficult to achieve high-quality sleep."

Using night mode or blue light glasses can help reduce light exposure, but these tools won't address the emotional and cognitive stimulation that keeps your brain active when it should be winding down. If you're still doomscrolling in bed with a filter on, your brain is likely still too activated to sleep well.

Can brain rot affect more than just your sleep?

The effects of excessive passive scrolling aren't limited to bedtime. Over time, the habit can show up in other areas of daily life.

• Reduced focus. If your brain gets accustomed to rapid, bite-sized content, it can become harder to concentrate on longer or more demanding tasks.

• Weakened memory. Research has found that constant exposure to online information can weaken the brain's ability to pay sustained attention, which in turn affects how well it stores and retrieves information.

• Heightened anxiety. Consuming a steady stream of negative content keeps the body's stress response engaged, which can increase anxiety over time.

• Brain fog and low motivation. Many people describe feeling drained or unmotivated after long periods of passive scrolling. It may feel satisfying in the moment, but it doesn't leave you better off.

These effects often compound, and brain fog during the day can lead to more scrolling as a way to pass time, which leads to more fog, which eventually bleeds into your sleep.

Can poor sleep make the scrolling habit worse?

Yes, and this is one of the reasons the habit is so hard to break.

Sleep deprivation impairs the prefrontal cortex, the area of the brain that manages self-control and decision-making. When you're running on poor sleep, the ability to resist picking up your phone drops significantly. This sets up a cycle:

• You scroll before bed, and your sleep suffers

• Poor sleep reduces your impulse control the next day

• With less self-control, you're more likely to scroll again that night

• The cycle repeats

Missing one night of sleep can lead to decreased cognitive function, trouble concentrating, headaches, and mood swings. Over time, sleep loss can increase the risk for chronic health conditions, including heart disease, high blood pressure, diabetes, and excessive daytime sleepiness.

Breaking the pattern usually starts with the nighttime habit. Changing what you do in the hour before bed tends to have the most immediate effect on sleep quality.

Are children and teens at higher risk?

The CDC estimates that about half of U.S. teenagers spend four or more hours a day on screens, and global estimates suggest adults may average over six hours online daily.

Data from the ABCD study, the largest long-term child brain development study in the U.S., found that adolescents with higher screen time were more likely to experience depression, anxiety, ADHD, oppositional defiant disorder, and physical symptoms like pain or nausea. Other research has connected high screen time in young people to delayed bedtimes, shorter sleep, and lower overall sleep quality.

But the issue isn't just about what screens are doing to young people. It's also about what screens are replacing.

Dr. Costantino Iadecola, director of the Feil Family Brain and Mind Research Institute at Weill Cornell Medical Center, explained: "Brain development requires diversity of exposures. When you are on your phone, you are not getting these other experiences."

The American Academy of Pediatrics recommends that families create screen-time plans together, prioritize offline activities, and distinguish between passive scrolling and purposeful screen use.

Signs that scrolling before bed is affecting your sleep

Some signs are easy to spot, while others are less obvious. Here's what to look for:

• You regularly stay up later than planned because you can't stop scrolling

• You have trouble falling and staying asleep after putting your phone down

• You wake up during the night and immediately reach for your phone

• You feel tired or unrested in the morning, even after enough hours in bed

• You feel anxious or mentally wired when you try to go to sleep

• Your daytime attention span has noticeably shortened

• You depend on caffeine to compensate for poor nights

If several of these apply, your nighttime screen habits may be playing a larger role in your sleep quality than you've considered.

How to protect your sleep from doomscrolling

You don't have to give up your phone. What matters is creating some distance between screen time and sleep time. Here are some practical steps you can start tonight:

• Set a screen cutoff time. Put your phone away at least 30 to 60 minutes before bed. This gives your brain enough time to transition out of its alert state.

• Move your phone out of the bedroom. If it's not within reach, you're far less likely to scroll at night or first thing in the morning. Try using a regular alarm clock instead.

• Replace scrolling with a wind-down routine. Reading a physical book, journaling, stretching, or taking a warm shower all work. The key is consistency. Doing the same thing each night signals to your brain that it's time for rest.

• Use grayscale mode. Removing color from your phone screen makes apps less visually stimulating and reduces the pull to keep scrolling.

• Turn off notifications in the evening. Alerts pull your brain back into response mode when it should be winding down.

• Try a natural sleep aid. If you're building better nighttime habits and want extra support, Sip2Sleep® can help. It's made with Tart Cherry Extract and Rafuma Leaf, two ingredients clinically studied for improving sleep quality and reducing insomnia severity. It's non-prescription, non-habit-forming, and designed to be taken nightly as part of a consistent bedtime routine.

The bottomline

While late-night scrolling may give you a quick dopamine hit, it's a pattern that can erode your sleep quality over time, and poor sleep makes the pattern harder to break. The good news is that small, consistent changes to your nighttime routine can make a real difference. Pair those changes with a natural sleep aid like Sip2Sleep®, and you're giving yourself the best chance to sleep better.

FAQs about doomscrolling, brainrot, and sleep

Can doomscrolling cause insomnia?

It can contribute to insomnia symptoms. Research has linked emotional engagement with social media and heightened mental activity before bed to both poorer sleep quality and greater insomnia severity. If you're regularly struggling to fall asleep after scrolling, it may be worth talking to your doctor.

Does night mode help with sleep?

While night mode helps reduce blue light from your screen, blue light combined with emotionally charged content is what disrupts sleep most. Night mode alone won't solve the problem if you're still consuming stimulating content before bed

How long before bed should I stop using my phone?

At least 30 to 60 minutes is the standard recommendation. The earlier you disconnect, the more time your brain has to wind down.

Can brain rot be cured?

While brain rot is not a medical condition, it can affect your daily life and eventually your sleep. The cognitive fog and sleep disruption associated with excessive screen time tend to reverse with small habits. A regular bedtime routine, reduced screen use before bed, and a natural sleep aid like Sip2Sleep® can help restore your sleep quality over time.

When should I see a doctor about my sleep?

If you've adjusted your screen habits and built a consistent sleep routine but still struggle to fall asleep, stay asleep, or feel rested, talk to your healthcare provider. Ongoing sleep problems may point to an underlying condition like insomnia, delayed sleep phase syndrome, or sleep apnea.
