What a Scientific Review Reveals About Digital Addiction

Think about this for a second. What’s the first thing you reach for when you wake up in the morning? And what’s the very last thing you look at before you go to sleep? For many of us, it’s a screen. We are more connected than ever, but this constant digital tether raises a real question researchers are working to answer.

We’ve all been there: that moment of anxiety when you check your screen‑time report, an evening lost to scrolling, or the uncertainty about where the line is between a helpful habit and a harmful compulsion.

But what if our digital habits aren’t just about personal willpower? What if they’re shaped by deeper needs, our social environments, and the way daily life is organized? Today we look at what an editorial overview in the International Journal of Environmental Research and Public Health reveals about that blurry line between healthy use and overuse. Read the review here: Lopez‑Fernandez (2021).

The paper synthesizes studies from the Special Issue “Internet‑ and Smartphone‑Use‑Related Addiction: Health and Education and Research,” with many contributions developed before and during the beginning of COVID‑19—highlighting how assessment, prevention, and practical approaches are evolving.

In this post, we’ll break down key findings from this research and offer suggestions to help you translate them into habits that protect your attention—especially on your Mac.

📊 Top Findings

Here are the findings from Lopez‑Fernandez (2021) that I find most relevant:

1. Beyond “Internet Addiction”

What does “internet addiction” really mean? The review argues that the catch‑all label is too broad for today’s diverse online behaviors. Instead, the editorial uses the term “Internet use‑related addiction problems.”

With that shift, attention turns to specific behaviors—excessive mobile phone/smartphone use, social networking, gaming, online gambling, and online shopping—because each can become problematic in different ways.

When these activities escalate, they can cause tangible harm: slipping performance at work or school, strained relationships, and reduced well‑being.

Each behavior also has its own context, risks, and motivations. Problematic gaming is not the same as social media overuse or compulsive online shopping. That’s why prevention and support are most effective when tailored to the behavior and setting—whether in healthcare, schools, or families. Recognizing these differences helps everyone choose smarter, more targeted ways to address digital challenges.

2. Where’s the line between fun and a real problem?

A helpful marker used in many of the studies summarized is control.

• Healthy engagement: You enjoy the activity and can put it down when you choose.
• Problematic use: Control is impaired—you keep going despite negative consequences or feel distress when you can’t connect.

Commonly examined indicators in the studies include repeated unsuccessful attempts to cut back, preoccupation, irritability or anxiety when unable to be online, and harms to school/work, relationships, or well‑being.

The editorial notes that impaired control can appear across different online activities, each with its own patterns and triggers—problematic mobile phone/smartphone use, gaming, social networking, online shopping, gambling, and pornography use.

3. It’s Not Just About Willpower

Why do some people slide into compulsive online habits while others don’t? The review makes clear: it’s not simply a matter of “just put the phone down.” It’s a complex mix of what’s happening inside us and around us.

On the individual side, traits and states such as impulsivity, loneliness, anxiety or depression, and low self‑esteem are commonly associated with problematic use in the studies summarized. On the environmental side, the constant availability of devices, everyday routines, social expectations to be “always on,” and family or peer norms all shape technology use and may increase the likelihood of unhealthy patterns.

In short, problematic internet use isn’t only about self‑control. Effective responses—prevention, education, and policy—should consider these broader social and environmental conditions, not just offer willpower tips.

4. Environmental Risk Factors

Our environment also plays a significant role. The studies summarized in the editorial point to factors such as constant connectivity expectations, everyday routines, and family or peer norms that can encourage heavy or unbalanced use.

Then came a sweeping environmental shift: the COVID‑19 pandemic. It didn’t just nudge habits—it accelerated them. The pandemic reshaped daily life and strengthened the role of technology in restrictive routines. Work, school, and socializing moved online, increasing screen time—often with less oversight—and creating higher‑risk conditions for vulnerable individuals. The same tools needed for school, work, and staying in touch also became a primary outlet for coping, blurring the line between necessary use and escape.

Personal traits—such as age, mental health, and personality—still matter, but they’re only part of the picture.

What you do online, where you do it, and your strengths and struggles all interact. The most effective responses combine personal skills—such as stress management and setting boundaries—with adjustments to the digital environment and everyday routines.

5. Prevention

The conversation around digital overuse is moving beyond quick fixes like “digital detox.” The editorial highlights growing attention to prevention and education.

Two trends to watch:

• Better screening tools: Psychometric scales and other assessments are being developed and refined, which can help identify problems earlier and monitor habits over time.
• Integrated approaches: Health and education settings are increasingly considered together to support digital skills, clarify use expectations, and manage exposure to online triggers in everyday contexts.

Bottom line: Prevention efforts are most promising when they are practical, evidence‑informed, and embedded in daily routines.

One more priority the review underscores: we need stronger study designs to move from correlation to causation. In other words, it’s not enough to see that social media use and anxiety co‑occur—we need longitudinal and experimental evidence to test whether (and when) one contributes to the other.

6. a Global Problem

Internet‑related problems are being studied across many regions, but they don’t look the same everywhere. The review points to a dual digital divide: differences in access to technology and differences in digital skills. Both shape risk and determine what kinds of support are realistic. Some regions—such as parts of Africa—remain underrepresented in the research base.

The COVID‑19 pandemic increased worldwide dependence on digital tools. That shift amplified benefits (e‑learning, staying connected) and risks (overuse, safety concerns), with the sharpest impacts where access and skills are uneven.

🤔 Why This Matters for Focus, Learning, and Work

• Always‑on environments can increase risk. When work, school, and social life all happen online, the line between productive use and problematic habits can blur—especially under stress.
• Assessment and education work hand in hand. Spotting problems is only the start; teaching practical digital skills and routines helps people stay ahead of them.
• Prevention is doable. Attention is shifting beyond quick fixes toward strategies that reduce exposure to triggers and support day‑to‑day self‑management.

Understanding what drives both healthy and unhealthy digital habits lets you make smarter choices—and shape your environment so focus and balance come easier, whether you’re working, studying, or simply spending time online.

Our relationship with technology is complex. It’s shaped by individual factors, everyday environments, and it accelerated during the pandemic. Research will continue to evolve, but the practical challenge returns to each of us:

In a world that is only becoming more digital, what does a healthy, balanced, and intentional relationship with technology look like for you?

❓ Reflection Questions for You

• How much time do you spend online each day?
• In what situations do you find it difficult to put your smartphone down?
• Which offline activities would you like to integrate more into your daily life?
