Can Teenagers Improve Their Sleep and Mood in a Hyperconnected World?
Teenagers aged 13 to 18 should sleep 8 to 10 hours per night to support optimal health. Unfortunately, most are falling short—averaging just 6.5 to 7.5 hours. This widespread sleep deprivation is more than a matter of being tired. It’s linked to issues with attention, memory, emotional regulation, academic performance, and even long-term physical health.
Why Aren’t Teens Sleeping Enough?
One major factor is the use of smartphones before bedtime. Studies show that screen time late in the evening can significantly disrupt sleep in several ways:
- Mental stimulation from apps and social media can keep the brain active at the exact time the body is trying to wind down.
- Notifications and vibrations interrupt sleep even after a person has fallen asleep.
- Blue light exposure from screens suppresses melatonin production—the hormone triggered by darkness that signals the brain it’s time to sleep.
These digital disruptions occur at a time when teenagers, unlike adults, typically have no external obligations like night shifts. They should be able to maintain a consistent and healthy sleep routine. But behavioral patterns, social pressures, and a general resistance to parental regulation often make simple fixes hard to enforce.
A Smarter Approach: Helping Teenagers Use Their Phones More Mindfully at Night
Most teenagers aren’t going to voluntarily turn off their phones or activate Do Not Disturb at bedtime—and that’s not surprising. Their devices are a core part of their social lives, entertainment, and identity.
Fortunately, phone manufacturers are already introducing features designed to reduce nighttime disruption. Many devices now include:
- Do Not Disturb and Focus Modes that silence notifications during set hours
- Night Shift or Blue Light Filters that reduce stimulating screen brightness
- Digital wellbeing dashboards that show usage patterns and suggest breaks
But features alone aren’t enough.
Some of the responsibility now falls on us—as adults, educators, and digital creators—to help teenagers actually use these tools. That means building awareness around why sleep matters and how even small changes in phone behavior can improve it.
Here are a few practical ideas that could support better nighttime routines:
- Quieter notifications: Social and messaging apps could default to lower notification volume between 9 PM and 11 PM on school nights, with silent mode after 11 PM.
- Gradual screen dimming: Devices could auto-adjust screen brightness progressively starting at 9 PM, aligning with circadian rhythms.
- Sleep awareness nudges: Once a week—preferably early in the week—phones or apps could serve short, visually engaging reminders about the benefits of sleep. These should feel like casual, algorithmic content drops, not lectures or health warnings.
Ultimately, the goal isn’t to restrict teens but to create space for healthier habits to take root. Subtle, consistent cues—embedded in the digital rhythms they already follow—are more likely to succeed than strict rules or moralizing.
Technology May Not Fix Everything—But Better UX Helps
We may not be able to stop teenagers from scrolling late at night—but we can design better digital environments. The way software and interfaces are built plays a direct role in behavior.
At Moveo One, we don’t tell people what to do. We help teams understand how users behave and where interfaces nudge, distract, or frustrate. If we can’t force teens to sleep earlier, we can at least help digital products respect their rhythms. Try it out and let us know what you think.
