Many of today’s college students are digital natives, having grown up in a world dominated by cellphones, the internet, social media and rapid technological advancements.
Coming of age alongside smartphones, however, has been linked to high rates of mental health concerns among Gen Z. A 2024 brief by the National Center for Health Statistics found that half of teenagers between the ages of 12 and 17 spent four or more hours on screens per day, and those teens were more likely to experience anxiety or depression symptoms. In 2025, 32 percent of college students reported moderate or severe levels of anxiety and 37 percent said they experience moderate or severe depression, according to the Healthy Minds Study.
As a result, more primary and secondary schools are introducing phone-free policies to improve children’s interpersonal skills and mitigate the harms of social media on their developing brains.
At some colleges and universities, students, faculty and administrators have identified opportunities to encourage healthy device habits and promote student success.
By the numbers: Students, in large part, are aware of their heavy device use and its potential link to poor academic outcomes.
A fall 2025 survey by Echelon Insights found that 54 percent of U.S. students say they spend five hours or more on recreational screen time, including scrolling social media, streaming or gaming. Of those students, 18 percent say they spend over six hours on their devices doing non–coursework-related tasks.
Another 2025 study of smartphone use surveyed students in the U.K. and found that among young adults aged 18 to 22, 73 percent spend more than four hours on their phone each day. Over three in four students also believe their smartphone negatively impacts their academic performance.
Finding ways to unplug, however, is difficult.
One research study from San Jose State University found that students who logged daily social media use reported a slight decrease in overall screen time over the course of a month, but simply monitoring screen time didn’t change the students’ high internet use. A Northwestern study of Americans who deactivated their Facebook account found leaving the platform did improve their mental health, but many just spent their time on other platforms rather than go offline entirely.
DIY: A 2023 survey of college students found that over 80 percent of respondents believe colleges and universities should do more to support breaks from technology. For practitioners looking to support students who are glued to their phones, other institutions and experts offer interventions that can encourage them to disconnect from devices.
- Encourage sleep. Excessive screen time is linked to poor health outcomes; it has been shown to disrupt students’ sleep and energy levels as well as their emotional health and cognition. First-year seminar instructors at the New York Film Academy require incoming students to complete a sleep log. Students track how many hours they sleep in a week, and the log provides a space for reflection and links healthy habits to academic and personal performance.
- Provide tech breaks. Fluid Focus’s survey of U.K. students found that 67 percent of students struggle to disconnect while they’re at home studying; an additional 16 percent said they have trouble disconnecting “during class.” Faculty and staff can help make it possible by assigning classroom activities that don’t require a device or creating phone-free class sessions.
- Establish phone-free environments. New York University’s president announced this fall that the university would implement device-free spaces, classes and events at campuses in New York, Shanghai and Abu Dhabi. Wyoming Catholic bans phones outright on campus; it also limits students’ internet access in the dorms to college emails and selected websites for class. Students leave their phones at the student life center and can check them out before they leave town.
- Support student leadership. The fear of missing out can also hinder students from spending less time on their smartphones, according to U.K. survey respondents. Some colleges and universities house student clubs that promote device-free engagement.
- Provide incentives. Researchers from Rensselaer Polytechnic Institute, the University of Pittsburgh and the University of Texas at Austin evaluated how an app that rewards students for staying off their phone during class could change behaviors. They found that app users were more likely to be focused, attend class and be satisfied with their academics, but weren’t necessarily more likely to study using the time saved by staying off their phone.
