New research reveals a surprisingly simple way to improve mental health and focus: turn off your phone’s internet. A month-long study found that blocking mobile internet access for just two weeks led to measurable improvements in well-being, mental health, and attention—comparable to the effects of cognitive behavioral therapy and reductions in age-related cognitive decline.
Researchers from multiple universities across the U.S. and Canada worked with 467 iPhone users (average age 32) to test how removing constant internet access would affect their daily lives. Instead of asking people to give up their phones completely, the study took a more practical approach. Participants installed an app that blocked mobile internet while still allowing calls and texts. This way, phones remained useful for basic communication but lost their ability to provide endless scrolling, social media, and constant online access.
The average smartphone user now spends nearly 5 hours each day on their device. More than half of Americans with smartphones worry they use them too much, and this jumps to 80% for people under 30. Despite these concerns, few studies have actually tested what happens when people cut back.
The results were significant. After two weeks without mobile internet, participants showed clear improvements in multiple areas. They reported feeling happier and more satisfied with their lives, and their mental health improved—an effect size that was greater than what is typically seen with antidepressant medications in clinical trials. They also performed better on attention tests, showing improvements comparable to reversing 10 years of age-related cognitive decline.
To measure attention, participants completed a computer task that tested their ability to stay focused over time. The improvements were meaningful—similar in size to the difference between an average adult and someone with mild attention difficulties. This suggests that constant mobile internet access may impair our natural ability to focus.
The study design was particularly strong because it included a swap halfway through. After the first two weeks, the groups switched roles—people who had blocked mobile internet got access back, while the other group had to block their internet. This strengthened the evidence that the improvements were caused by reduced mobile internet access rather than other factors.
“Smartphones have drastically changed our lives and behaviors over the past 15 years, but our basic human psychology remains the same,” says lead author Adrian Ward, an associate professor of marketing at the University of Texas at Austin, in a statement. “Our big question was, are we adapted to deal with constant connection to everything all the time? The data suggest that we are not.”
An impressive 91% of participants improved in at least one area. Without the ability to check their phones constantly, people spent more time socializing in person, exercising, and being outdoors—activities known to boost mental health and cognitive function.
Throughout the study, researchers checked in with participants via text messages to track their moods. Those who blocked mobile internet reported feeling progressively better over the two weeks. Even after regaining internet access, many retained some of their improvements, suggesting the break helped reshape their digital habits.
Interestingly, the benefits weren’t just from less screen time. While phone use dropped significantly during the study (from over 5 hours to under 3 hours daily), the improvements appeared linked specifically to breaking the habit of constant online connection. Even after getting internet access back, many participants kept their usage lower and continued feeling better.
One surprising finding involved people who started the study with a high “fear of missing out” (FOMO). Rather than making their anxiety worse, disconnecting from mobile internet led to the biggest improvements in their well-being. This suggests that constant access to social media and online updates may fuel digital anxiety rather than relieve it.
Blocking mobile internet also helped participants feel more in control of their behavior and improved their sleep. Without instant access to endless entertainment and social media, people reported having better control over their attention and averaged about 17 more minutes of sleep per night.
However, sticking to the program was difficult—only about 25% of participants kept their mobile internet blocked for the full two weeks. This highlights how dependent many of us have become on constant connectivity. Still, even those who didn’t fully adhere to the program showed improvements, suggesting that simply reducing mobile internet use can be beneficial.
The researchers noted that a less extreme approach might work better for most people. Instead of blocking all mobile internet, limiting access during certain times or restricting specific apps could provide similar benefits while being easier to maintain.
The takeaway is simple: reducing mobile internet access—even temporarily—can help improve well-being, mental health, and focus. While not everyone is ready to disconnect completely, finding ways to limit our online exposure could make us happier, healthier, and more present in our daily lives.
