Does Using Screens Before Bedtime Really Mess Up Your Sleep?

Screens are everywhere. We use them for work, fun, and winding down before bed. But there's a question: Does using screens before bedtime really mess up your sleep?

We're here to clear things up and help you understand how screens can affect your sleep.

The Connection Between Screens and Sleep

  1. Blue Light Exposure: The light from screens, especially the blue light, can mess with our body's internal clock. This light can mess up the sleep hormone called melatonin, making it hard to fall asleep.
  2. Falling Asleep Late: Watching TV or playing on your phone before bed can keep your brain active, making it difficult to fall asleep when you want to.
  3. Less Sleep: Sometimes, we stay up too late with screens, and this means we get less sleep. It's easy to lose track of time when we're on screens.

The Facts and Myths

  1. Blue Light's Impact: Studies show that blue light before bed does affect sleep. It lowers melatonin levels, making it harder to sleep well.
  2. Falling Asleep Late: It's true that screens can keep you awake for longer. Your brain stays active, making it harder to doze off.
  3. Less Sleep: Research tells us that more screen time often means less sleep, especially in young people.

How to Make It Better?

  1. Use Blue Light Filters: Many devices have settings to reduce the blue light. Using these filters in the evening can help protect your sleep.
  2. Set a Time to Stop: Decide on a time when you'll stop using screens before bed. This can help your body prepare for sleep.
  3. Read a Book: Instead of screens, try reading a real book. It's a relaxing activity that doesn't have the same impact on your sleep.
  4. Create a Cozy Sleep Space: Make your bedroom a comfortable place to sleep. Dark, quiet, and comfy environments can help you get better rest.
Everyone's Different → Remember, the effects of screens before bed can be different for each person. Your age, how much you use screens during the day, and your sleep habits all play a role in how screens affect your sleep.

Additional Ways Screens Impact Sleep

  1. Emotional Stimulation: Screens can also stimulate your emotions, especially if you're watching something intense or engaging. This emotional arousal can make it harder to relax and fall asleep.
  2. Mind Engagement: Scrolling through social media, reading news, or playing games on your device can keep your mind engaged. It's like giving your brain a jolt of caffeine, making it harder to wind down.
  3. Social Comparison: Social media platforms can lead to social comparison, which can affect your self-esteem and contribute to feelings of anxiety or depression. These emotional struggles can, in turn, impact your sleep.

Sleep Disorders and Screens

  1. Insomnia: Prolonged exposure to screens before bedtime can lead to insomnia. Insomnia is characterized by difficulty falling asleep, staying asleep, or experiencing restorative sleep.
  2. Delayed Sleep Phase Disorder (DSPD): DSPD is a sleep disorder where your body's natural sleep-wake cycle is delayed, making it difficult to fall asleep at a socially acceptable time. Screens before bed can worsen this condition.

Creating a Screen-Free Bedtime Routine

  1. Wind Down: Instead of screens try calming activities before bed. Consider taking a warm bath, practicing relaxation techniques like deep breathing, or meditating.
  2. Avoid Screen Time Before Bed: Make a rule to avoid screens at least an hour before bedtime. This gives your brain time to relax.
  3. Limit Exposure: If you can't avoid screens entirely, try to limit exposure to non-engaging content. For example, avoid action-packed movies or heated social media debates.


In conclusion, screens before bed can truly affect your sleep, and this is a fact, not a myth. Blue light, staying up late, and getting less sleep are all real consequences of too much screen time. But you can take steps to help your sleep, like using blue light filters, setting a screen curfew, and creating a cozy sleep space. By being aware of how screens can harm your sleep and making changes, you can enjoy better sleep and feel more refreshed. So, next time you're tempted to stay up late with screens, think about the impact on your sleep. Good night, sleep tight!

FAQs About Screens and Sleep

Double-tap initially on the question to view the answer
1. Is it okay to use my smartphone or tablet as an e-reader before bedtime?

Yes, using your device as an e-reader with a blue light filter turned on is a better option compared to watching videos or engaging in highly interactive content. However, it's still a good idea to transition to a physical book for the last hour before sleep for the best results.

2. How long before bedtime should I stop using screens for optimal sleep?

Ideally, you should stop using screens at least an hour before bedtime. This allows your brain to wind down and for melatonin levels to rise, making it easier to fall asleep.

3. Can I watch TV in bed without it affecting my sleep?

Watching TV in bed can still expose you to blue light and stimulate your brain. If you're going to watch TV in bed, try to limit it to a reasonable duration, use a blue light filter, and avoid particularly engaging or exciting content.

4. What about using "night mode" or "dark mode" on my device? Does that help with sleep?

Night mode or dark mode can reduce the amount of light emitted from your screen, which is beneficial. However, it's still a good practice to combine this with a blue light filter, especially in the evening hours.

5. Are there any specific apps or tools that can help me monitor and manage my screen time before bed?

Yes, there are many apps and features on smartphones and tablets that can help you track and limit your screen time. You can set app-specific time limits, enable "Do Not Disturb" modes, or use apps that remind you to take breaks from your screen.

6. Does the type of content I consume on screens matter for my sleep?

Yes, the type of content matters. Engaging, stimulating, or emotionally charged content is more likely to affect your sleep negatively. Opt for calming or non-engaging content if you plan to use screens close to bedtime.

7. Can I catch up on sleep during the weekends if I use screens before bed during the week?

While it's possible to recover some lost sleep during the weekends, it's not a sustainable solution. Irregular sleep patterns can lead to a phenomenon known as "social jetlag," which can have long-term health consequences. It's better to maintain a consistent sleep schedule throughout the week.

8. I use screens for work late at night. What can I do to minimize the impact on my sleep?

If you have to work on screens late at night, try using blue light filters and follow a wind-down routine after work to signal to your body that it's time to sleep. Limit caffeine and make sure your sleep environment is conducive to rest.
