Spending just a couple of hours each day scrolling through social media could be significantly increasing the risk of loneliness among young adults, a major nationwide study has revealed. Researchers surveyed almost 65,000 students, aged between 18 and 24, across more than 120 American colleges. The findings indicate that dedicating as little as 16 hours per week to these platforms is enough to heighten their susceptibility to feelings of isolation.
For those students who are the heaviest users, spending upwards of 30 hours a week on social media, a staggering 38 percent reported experiencing loneliness. These results carry serious implications for the mental and physical wellbeing of college students, a demographic where almost all individuals engage with social media daily, according to the Pew Research Center.
The detrimental impact of loneliness on health is well-documented. The World Health Organization estimates that it contributes to approximately 100 deaths per hour globally. Dr. Madelyn Hill, an assistant professor at Ohio University and a co-author of the study, highlighted the gravity of the situation in a statement. “We know that people who are lonely are more likely to become depressed,” she explained. “We also know that those who are lonely are more likely to die early.”
Further research suggests that the health risks associated with loneliness are comparable to those of smoking. The Centers for Disease Control and Prevention identifies it as a significant risk factor for a range of serious health issues, including heart disease, type 2 diabetes, depression, anxiety, dementia, suicidal thoughts, and premature death.
The study’s authors propose a potential cyclical relationship between excessive social media use and loneliness. They theorise that not only does overuse of social media contribute to feelings of isolation, but loneliness itself can also drive individuals to spend more time on these platforms. The researchers also acknowledged that some students might be underestimating their actual screen time, which could influence the perceived timeframe for loneliness to develop after using social media.
Recommendations for Academic Institutions
In light of these findings, the researchers are urging academic institutions to take proactive steps. They advocate for enhanced education for students regarding the potential negative effects of excessive social media consumption. Furthermore, they encourage universities to actively promote real-world social events on campus to foster genuine human connection.
“Young adulthood is a time of many changes, from leaving home for the first time, to starting college and forming new friendships, and it is vital that colleges and universities do all they can to help their students forge connections with others,” stated Dr. Hill.
The Growing Problem of Loneliness Among Young Adults
Loneliness is not an isolated issue; it’s a widespread concern affecting more than half of all Americans, as indicated by a 2025 report from the American Psychological Association. Certain demographic groups are disproportionately affected, with adults younger than 30 identified as one of the most likely groups to experience these feelings, according to the Pew Research Center.
This age group also tends to be more prone to using drugs or alcohol when feeling lonely. A 2024 study revealed that over 20 percent of college students suffer from substance use disorder. While college students are reportedly drinking less than in previous years, there has been a “significant increase” in daily marijuana use, according to Texas A&M Health.
Technology: A Double-Edged Sword
While technology can offer a seemingly easy solution for lonely students seeking connection, experts warn that it may ultimately do more harm than good. Dr. Saul Levin, CEO of the American Psychological Association, commented on the complex nature of online interactions. “In some cases, it seems to be helping us reach people who become part of our inner circles or to communicate with those who already are,” he explained.
However, he cautioned, “Distracting yourself when you’re feeling lonely with social media might be a double-edged sword: while it can connect, it can also lead to feelings of missing out, and we need to make sure we remain conscious of its effects on our mood.” This highlights the critical need for a balanced approach, where digital interactions complement, rather than replace, meaningful face-to-face connections. The study underscores the importance of fostering a campus environment that prioritises genuine social engagement and provides students with the tools and opportunities to build strong, supportive relationships.
