When you were a teenager and couldn’t sleep, the options were slim. You could read, stare at the ceiling or count sheep. That was it. Today’s teens have many more choices now that screens and tech have moved into the bedroom, and we’re all learning—still—what the long-term impact and benefits of that cultural shift will be.

Screens aside, teenagers are already undergoing a big sleep shift hormonally as they transition from childhood to adulthood. Melatonin—the hormone that kicks in at night to help you sleep—peaks between 2 and 4 AM and gradually decreases as the sun rises. For my teenage clients who game, that can be the best time to play with friends in different time zones. That’s problematic because teenagers are wired to connect, and they’re finding connections online with other sleep-deprived teens.

So there are social, hormonal and developmental reasons for sluggish mornings and late nights of gaming, chatting with friends and scrolling social media. It’s no surprise that teens today are facing a sleep crisis, as school start times are earlier and parents struggle to get teens going in the morning.

As a parent coach and cognitive specialist, I help parents understand their child’s brain development so they can make better parenting decisions. For this article, I interviewed 20 people between the ages of 13 and 21 to ensure that the ideas listed here would make a difference. All the teens I interviewed are clients of mine who are working with me to curb binge-gaming. What I’ve learned: When it comes to teens, sleep and screens, neuroscience can help you retrain your teen’s brain for optimal sleep.

‘…Neuroscience Can Help You Retrain Your Teen’s Brain For Optimal Sleep.’ By Beatrice “Bea” Moise, Cognitive Specialist And Patenting Coach | Teens And Sleep

But first, your teen’s brain and sleep

The teenage brain is still developing. The prefrontal cortex—which is the part of the brain responsible for dopamine monitoring and control, impulse control, and cognitive control—is not fully developed until the age of 25. Which means that teenagers require more guidance than you might think—or than they might be willing to admit.

Meanwhile, the adolescent brain is producing growth hormones, stress hormones and sex hormones. Hormones are the brain’s messengers. They take information from the brain’s hypothalamus and pass it on to the body to tell it what to do. To carry these messages, hormones need transportation routes, such as the pineal gland, the pituitary gland and the thyroid gland.

Hormone fluctuation is typical during the teenage years, and this can cause fatigue, anxiety and depression, all of which can have a big impact on your child’s development. This makes things tricky for a parent, because what seems like unusual behavior might be typical developmental behavior rather than a sign that something’s wrong.

So what’s the importance of sleep to teens? While teens sleep, the pituitary gland releases growth hormones for tissue repairs, and it needs to be working optimally. In the simplest terms, the pituitary gland sends messages to the body during deep sleep and works like a cleanup crew to flush toxins, reorganize and get things ready for the next day. If this cleanup process doesn’t happen between the peak melatonin hours of 2 and 4 AM, or if it’s interrupted by screen use, your teen’s development could be impacted.

What’s the link between screens and hormones?

Prolonged exposure to screens can boost serotonin. Serotonin is one of the “feel-good” hormones and boosts a feeling of connection and belonging. Although boosting serotonin by streaming a television series can make your brain feel good, this can also be a problem. For example, if you watch a video series from start to finish in one day and feel good doing it, you’re less likely to get up and move or take a physical break. The brain is content; therefore, the body thinks it’s content with the lack of movement.

Blue light from screens can impact the production of melatonin. Screens produce a spectrum of colors, which can increase focus and attention during the day. In the evening, however, when the body is supposed to be preparing for sleep as the sun goes down, blue light makes the brain assume it’s still daytime and can limit the release of melatonin, which regulates the sleep cycle.

Gaming and interactive screen time also release cortisol. Cortisol is a stress hormone that puts the body and brain in a heightened state of alertness. It can be triggered when your child engages in interactive screen activity before bed, which can make it more difficult to wind down into a peaceful slumber.

How much sleep do teens need?

Teens need an average of eight to 10 hours of sleep per night. Yet studies show that the average teen only gets about seven hours of sleep.

Here are four steps to take that can help your teen with sleep.

Paso 1

Reset the internal clock.

If your teenager consistently stays up late with screens, the first step is to decondition that behavior and reset the body’s internal clock. That’s going to take some time—for the same reason that a trendy, short-term diet doesn’t work as well as lifestyle changes do for maintaining healthy habits. Recalibrating the brain to engage in healthier habits can take an average of 66 days. And for a new routine to become an automatic response, consistency is important. The goals are to stop staying up late, eliminate excess screen time and stop avoiding sleep.

Paso 2

Move screens out of the bedroom.

It’s estimated that 75% of teens have electronics in their bedrooms. Move gaming devices and screens out of their bedrooms, but be sure to ask your teen where these devices should go instead, or this could be perceived as a punishment rather than support. Developmentally, teenagers have a hard time avoiding temptation, so removing these devices or setting a time when they can be used can help your teen practice impulse control and strengthen self-control overall.

Paso 3

Set a time to connect after screens go off.

Create a consistent bedtime schedule and routine. Teenagers are still kids; they still want to tell you about their day and connect with you. And this is also a chance to create the kind of situation that boosts serotonin in the right direction: toward a connection with you. If there’s an activity or routine they can look forward to after screens, it’s easier to turn screens off. But this is not the time to do chores or mow the lawn. Once the screens go off, plan to talk together about that winning move in their favorite game or something new they’ve learned that day. The goal is to create a time when you can build a connection to you, the parent—and boost serotonin.

Paso 4

Make time for sleep cues.

There are several tech-free ways to relax prior to bedtime that can give your family members a more natural serotonin boost.

Use a sleep cue.

Drink water, stretch and dim the lights. These activities should be done around the same time each night to tell your brain that it’s time to go to sleep.

Take a hot bath.

Studies show that body temperature decreases once you’re out of the hot water, which induces sleepiness.

Turn on the white noise.

White noise has been proven to increase the quality of sleep and can help with falling asleep quickly. Smart speakers and Bluetooth speakers can maintain a screen-free environment while helping your child get a better night’s sleep.

Be patient. This is going to take time. One of the teenage girls I’m working with tried all the sleep cues and said they really helped. She asked her parents to encourage her to keep up the routine—not in a nagging way, but in a supportive way. Teenagers want parental affirmation without being micromanaged: They want to hear “good job.”

So talk together about creating a new routine and let your kids do the work—but check in periodically to ask if they need anything. And hopefully, everyone can get a better night’s sleep.

Smart sleep strategies for teens

  1. Reset the internal clock. Set a bedtime and have teens cut back on nightly screen use. Consistency is key here, so help them stay on track.
  2. Move screens out of the bedroom. Work with teens to find a better place for screens so it feels collaborative—and not like punishment.
  3. Make time for connection. Give teens something else to look forward to at bedtime, like talking with you about their day or their interests.
  4. Try some sleep cues. Do things that let your body know it’s time to wind down, like dimming the lights, taking a hot bath or listening to white noise.
