Secondhand screen time may be just as dangerous as secondhand smoking

Research suggests that if the desire for a phone builds in infancy, it can become second nature.

The Environmental Protection Agency first warned of secondhand smoke in 1991, some 30 years after scientists determined that smoking cigarettes causes cancer. Today, a growing body of research points toward a new indirect health hazard.

Just as frequently being around other people while they smoke can cause cancer, heart disease, lung disease, and other ailments, what I call “secondhand screen time” could be endangering children.

By not limiting their own phone use, parents and other caregivers may be unwittingly setting kids up to be addicted to screens.


A decade ago, the unwillingness—or perhaps the inability—of the college students in my writing classes to stay off their phones for 50 minutes at a stretch catalyzed my interest in screen use. And my students have only grown more unwilling to put down their phones, a trend that has also gotten worse outside of my classroom.

Curious about my students’ phone use, I began researching screen addiction and conducting my own surveys. Roughly 20% of my students have used the word “addiction” when describing their phone habits, and many more have expressed misgivings about their phone use.

While I encourage them to examine their habits, I blame students less for their tech addiction than I did a decade ago. They’ve learned this behavior from adults—in many cases since the moment they were born.

Checking Twitter in front of kids is not the same as blowing smoke in their faces. Smartphones and cigarettes do, however, have some things in common. Both are addictive, and both became wildly popular before researchers learned about their addictive properties and health dangers.

On average, American adults touch their phones over 2,500 times a day. According to the American Psychiatric Association, that fits the definition of addiction: “A condition in which a person engages in the use of a substance or in a behavior for which the rewarding effects provide a compelling incentive to repeatedly pursue the behavior despite detrimental consequences.” While researchers continue to study the effects and extent of phone use, the scientific consensus is that phone addiction is real.


What’s a parent to do while nursing or when an infant falls asleep on one’s chest?

Perhaps they’ll read the news, check email, text friends, or scan social media parenting groups. A phone or tablet can be a portal to the rest of the world—after all, caring for small children can be isolating.

But kids, even babies, notice these habits. They see parents reach again and again for a seemingly magical object that glints and flashes, makes sounds, and shows moving images.

Who wouldn’t want such a wonderful plaything? Trouble is, if the desire for a phone builds in infancy, it can become second nature.


Some researchers have already found links between excessive screen time, particularly phone use, and attention deficitsbehavioral issuessleep problemsimpaired social skillslonelinessanxiety, and depression.

Researchers from Cincinnati Children’s Hospital Medical Center and Israel’s Educational Neuroimaging Center recently published a study in JAMA Pediatrics that focused on cognitive-behavioral risks of exposing preschool-age kids to screen-based media. That includes video games, TV, websites, and apps. Phones are particularly problematic, the study found, because they provide mobile access to all of this media. They found that screen exposure impedes the formation of nerve systems involved in language development, expression, and reading skills.

These findings point to yet another consequence of excessive screen time, especially for younger kids. Since 96% of Americans have phones, many babies are exposed to screens soon after they’re born, and the stakes of such exposure are becoming better understood.

To be sure, it’s hard if not impossible to assess how much time Americans are spending looking at screens given the countless different ways that people use their devices. And because not all screen time is equally good or bad for you, some experts are calling for a “Human Screenome Project” to assess what we’re doing on our screens and to figure out what the consequences might be.


When younger kids are exposed to harmful, habit-forming behaviors, such as smoking cigarettes or gambling, they’re more likely to become addicted to those same substances or behaviors. Exposure to secondhand smoke itself also can make kids prone to cigarette addiction.

While scientists don’t yet know for sure if that happens to kids who observe their parents’ phone use, there’s ample evidence that kids learn from and mimic their parents’ behaviors. If children see their parents do something they’re not allowed to do, that behavior doesn’t seem bad or wrong, and they may desire the “forbidden fruit” all the more…
