Social media platforms like Instagram, Snapchat, and TikTok have become social hubs, creative outlets, and in some cases, lifelines. But with students spending an average of 4.8 hours a day on these sites, they also bring serious risks that schools and parents can no longer afford to ignore.1
The previous U.S. Surgeon General has issued multiple warnings about the mental health impact of social media on youth, highlighting its links to anxiety, depression, and disrupted development. As young people spend more time online, often trading sleep and face-to-face interaction for likes and comments, educators and caregivers are left asking: How do we protect them?
In a recent Navigate360 webinar, Dr. Scott Poland, renowned school psychologist and Director of Suicide and Violence Prevention at NSU Florida, joined SVP of Detection & Prevention, Thom Jones, to discuss this critical issue. The conversation provided not only insight, but actionable guidance for building more sustainable student mental health support. Watch the full webinar here.
Understanding the Effects of Social Media on Youth
Despite its pros and cons, the reality is this: most youth spend hours a day on social media sites. According to the Pew Research Center:
- 95% of teens now report using YouTube
- 67% use TikTok
- ~60% use Instagram and Snapchat.2
And according to recent numbers from the American Psychological Association:
- 4.8 hours — The average time U.S. teens spend on social media daily, with YouTube, TikTok, and Instagram making up 87% of their total screen time.
- 41% — The percentage of high-use teen social media users who rate their mental health as poor or very poor, compared to just 23% among low-use teens.
- 60% — Among heavy social media users, those with low parental monitoring and weak relationships are more than twice as likely to report poor mental health.1
With this level of saturation, social media has a growing influence on mental health, identity, and relationships. Dr. Poland emphasized that we can’t pretend to fully understand the pressure teens face because we didn’t grow up in a world where our worth was constantly measured in views and likes.
“We can’t say to an adolescent today, ‘I understand,’ because we didn’t grow up in the world they live in. But we can say, ‘Help me understand.’”
The Mental Health Impact of Social Media on Youth
Increased Depression, Anxiety, and Suicide Risk
The numbers are staggering. According to the CDC’s Youth Risk Behavior Survey, 40% of high school students report feeling sad or hopeless for weeks at a time. Among girls, that number rises to over 50%. Social comparison, cyberbullying, and constant fear of missing out are just a few of the drivers behind these trends.3
“Some teens are online nearly every waking hour. That kind of exposure to curated perfection and negative content is going to affect your self-esteem and mental state,” Dr. Poland noted.
Excessive time on social media feeds also opens the door to serious risks like eating disorders, self-harm, and even suicide—especially when young people feel isolated or ashamed of what they’re experiencing.
Sleep and Social Deprivation
One of the most immediate side effects of excessive social media usage is disrupted sleep. Many students go to bed with their phones, waking throughout the night to check notifications or respond to messages.
Dr. Poland calls this tradeoff “more screen time, less green time.” Kids are losing essential rest and missing out on outdoor play, creativity, and real-life connection.
The consequences? Chronic fatigue, lower academic performance, social withdrawal, and a decline in the face-to-face communication skills critical for emotional regulation and relationship-building.
The Role of Schools & Parents in Minimizing Harm
Technology Is a Privilege, Not a Right
In one of the webinar’s most striking anecdotes, Dr. Poland recalled a mother who insisted her 13-year-old daughter needed to keep her phone overnight “in case her friend needed her.”
“Maybe that friend needs to talk to her own parents,” Dr. Poland responded. “Adolescents don’t need to be reachable 24/7.”
Boundaries are essential. Schools and families should promote tech-free times, especially around dinner, bedtime, and early mornings. A simple rule like “no phones in bedrooms overnight” can have a major positive effect.
Modeling Healthy Technology Use
Students aren’t just watching TikToks, they’re watching us. Adults who constantly check their phones during meals or conversations reinforce the idea that screen time is a priority over human connection.
Dr. Poland encourages families to commit to tech-free meals, regular screen-time “blackouts,” and shared expectations around digital etiquette.
You might even consider a screen-time contract: a simple, age-appropriate agreement that sets boundaries, expectations, and consequences around device use.
Positive Uses of Social Media
While it’s easy to focus on the negative effects of social media on youth, it’s also important to acknowledge its value, especially for marginalized students who may find online communities that reflect their identity, creative side, and offer support they can’t find elsewhere.
Dr. Poland noted that there are benefits to creativity, self-expression, and connection, especially when social media use is balanced and supported by adult involvement.
“It’s not about banning social media—it’s about helping kids use it with intention and limits.”
What Schools Can Do
Establish Clear Policies on Smartphone Use
From Utah to Florida, more districts are re-evaluating cell phone use policies, often banning them during class or creating designated phone-free zones. Dr. Poland shared that even student-led initiatives—like blackout days—can lead to a noticeable difference in focus and peer interaction.
The key is community input. Involve staff, parents, and students in shaping policies that are clear, enforceable, and focused on student well-being, not punishment.
Promote Trusted Adult Relationships
In a world where teens are spending nearly five hours a day on social media, it’s easy for their emotional needs to go unnoticed—especially when their struggles are happening behind a screen. That’s why one of the most powerful antidotes to the negative effects of social media on youth is human connection.
A trusted adult—someone who checks in, listens without judgment, and notices when something is off—can be a life-changing anchor for students navigating the pressures of online life. When students feel isolated, anxious, or overwhelmed by what they see online, having a go-to adult makes them far more likely to seek help before a situation escalates.
Some districts, like Olentangy High School in Ohio, have taken a proactive approach by creating spreadsheets that ensure every student is matched with at least one adult who knows them personally and is equipped to support them through tough times.
“When a student is in crisis, we need to know whose wing they’re under. Every student should have someone at school they can turn to,” said Navigate360’s Thom Jones.
Encourage your team to identify and connect with students who may be flying under the radar. Especially for teens caught in the comparison trap or cyberbullying cycle, one strong relationship can be the difference between silent suffering and real support.
Educate Parents Through Every Touchpoint
Dr. Poland emphasized that screen time should be part of every parent conversation, not just special presentations.
Include five minutes on screen habits in PTA meetings, parent-teacher conferences, or back-to-school nights.
One of his favorite rules of thumb? 10 minutes of screen time per day per year of age.
That means an 8-year-old should have no more than 80 minutes per day across all screens.
Small, consistent reminders can spark bigger shifts in family habits.
Supporting Youth Through Balance & Connection
Social media isn’t going away, and it’s not inherently harmful. But the amount of time, the type of content, and the lack of boundaries can create very real mental health issues for today’s teens.
That’s why schools and parents need to move beyond fear and into partnership. We need proactive policies, open conversations, healthy role models, and consistent reinforcement of face-to-face connection.
As Dr. Poland reminded us, it’s not just about managing screen time—it’s about giving kids purpose and people they can rely on.
“Every child needs someone who shows up for them. And every student should know there’s an adult at school who has their back.”
