Spending Too Much Time Scrolling? Cutting Back Benefits Well-Being

Treating your smartphone like a flip phone opens up time for enjoyable activities

You’re not alone if you have a complicated relationship with your smartphone. We may depend on them to connect with others, find information and map our way around town, but many of us use them more than we’d like. In a 2022 Gallup poll, 47 percent of people 50 to 64 and 30 percent of those 65 and up said they spend too much time on their smartphones.

Stepping away can be hard, but a new study suggests making the effort may be worth it. People who were told to block the internet from their smartphones for two weeks reported better mental health and well-being. And by one standard test their attention spans improved as if they’d subtracted a decade from their age, researchers reported in the journal PNAS Nexus.

Why the improvements in well-being? The researchers say participants spent more time socializing in person, exercising and being in nature, all of which benefit mental and physical health. 

The experiment included 467 adults, ages 18-74, who were told to use an app that blocked all mobile internet access for two weeks (and tracked how well participants complied). Users could send and receive calls and texts but couldn’t access email or social media, read news apps or browse the internet. “Basically, this app turns people’s smartphones into flip phones,” says study author Noah Castelo, an assistant professor of marketing at Alberta School of Business in Edmonton. 

Study participants were randomly assigned to one of two groups. One group began the blocking experiment immediately, while the other acted as the control group for two weeks, able to use their phones as normal. After two weeks, the groups switched.

After two weeks of the experiment, about 70 percent of participants reported better mental health and 73 percent reported improved well-being. At the beginning and end of the study, participants took a standard computer-based test that assessed how well they sustained visual attention to a challenging task. “Researchers have found that after the age of 40, people’s performance on this task starts to decline a little bit every year,” Castelo says. After the smartphone blocking, participants improved on the test as if they’d reversed 10 years of age-related decline. More than 90 percent of participants improved on at least one of the key outcomes: mental health, well-being and attention.

The study shows that “there are practices you can engage in to support a more successful detox from your internet, specifically the phone,” says Kelley Cours Anderson, assistant professor of marketing at the College of Charleston. She studies use of digital technology and well-being but was not involved in this research. 

The study is particularly significant, says Nick Allen, professor of clinical psychology and director of the Center for Digital Mental Health at the University of Oregon, also not involved in the study. It shows a cause-and-effect relationship, he says, between smartphone use and measures of psychological health, in contrast to a lot of research in the field designed only to show correlations between them.

Many participants had a hard time staying off the apps. Of the original group that committed to the study, 266 set up the blocking app, but only 119 kept the app active for at least 10 of the study’s 14 days. “Being able to have endless entertainment and communication with people around the world at our fingertips is obviously valuable,” Castelo says. Access to those functions is a hard habit to break, especially social media apps such as Facebook, Instagram and TikTok, which are designed to consume as much of our attention as possible, he says.

One limitation of the study is that the participants were already highly motivated to change their smartphone use, so it’s unclear whether a less motivated group would experience the same effects. Participants also knew the study was about smartphone use and well-being and might have expected they were supposed to feel better during the period of restricted internet access and reported that to researchers, even if they didn’t. The results are based on data from the entire group – including those who didn’t stick to the restrictions – though the positive effects were larger for people who kept the block in place for at least 10 days. “Any kind of reduction that you can manage in how much time you’re looking at your phone can probably be helpful,” Castelo says. 

Here are some tips for cutting back your smartphone scrolling:

It’s OK to start small. You can use an app to block or limit time or your phone’s own settings to set time limits on different apps or websites. Stepping away entirely from your phone for certain periods seems helpful, but it doesn’t have to be two weeks, Anderson says. Try a day or a few hours, she suggests.

Figure out which smartphone functions are useful to you. “Learn to tune into when your phone use is helpful and enjoyable and when it feels unproductive and, for want of a better term, soul-destroying,” Allen says. For example, evidence suggests that actively using your phone – such as communicating with family and friends, practicing your Italian, solving a puzzle – is better than mindlessly scrolling social media or other content, he says. 

Fill your life with plenty of offline activities, preferably with others. Take a cue from the people in the study and replace digital time with physical activity, time in nature or a new hobby, for example, and do it with other people. Forging social connections can help ease the FOMO some people feel when they step away from their smartphones, Anderson says, adding, “We are social beings.”
