PLEASE! Do Not Give Your Children Smartphones

Updated: Feb 25


Smartphones Are an Adult Device

Smartphones, while powerful and versatile tools, are primarily designed for adults, not children. They offer a wide range of functionalities that can have unintended consequences, especially when used by young, developing minds. Children and teenagers often lack the maturity and life experience to understand the long-term impact of their digital actions. This is partly due to the fact that the frontal cortex, the region of the brain responsible for executive functioning, impulse control, and decision-making, is the last to fully mature. Research indicates that the frontal cortex doesn't reach full maturity until a person's mid-20s (Johnson et al., 2009). As such, children are not equipped to handle the potential risks associated with smartphone use, including exposure to inappropriate content, cyberbullying, or the negative effects of excessive screen time on mental and physical health. Allowing children to use smartphones at an early age could have lifelong consequences, especially if their digital actions lead to harm or poor decision-making.



The Harmful Effects of Smartphones on Attention and Mental Health

Excessive screen time has been strongly linked to attention problems in children, with significant research highlighting the negative impact of prolonged exposure. A large study conducted on 5-year-olds compared the attention spans of children who spent less than 30 minutes on screens daily with those who spent over two hours. The results were striking: children with the highest screen exposure were 7.7 times more likely to meet the criteria for an ADHD diagnosis (Wu, 2022). This study found that screen time was a more significant predictor of attention problems than even sleep deprivation, socioeconomic status, or parental stress, underscoring the powerful impact of screens on a child’s cognitive development.

Additionally, research from Dr. Jean Twenge and Dr. Keith Campbell (2019) determined that the only safe amount of social media use for youth was 30 minutes or less per day. Beyond this threshold, negative psychological effects such as increased anxiety, depression, and loneliness were observed. However, with the rise of platforms like TikTok, Twenge’s research now suggests that there may be no safe amount of social media exposure for children. Furthermore, a comprehensive review conducted by Stiglic (2018) found no convincing evidence of health benefits from screen time, indicating that it is unlikely to have a positive impact on young people’s well-being. Given that smartphones are the primary means through which children access social media, the simplest and safest approach is to avoid giving them smartphones altogether to reduce the risks of attention problems, psychological harm, and the lack of health benefits associated with screen use.



Smartphones Are a Distraction in Schools

The vast majority of schools recognize that smartphones interfere with learning and classroom focus. During the 2021-22 school year, 76.1% of K-12 public schools in the United States banned non-academic cell phone use (Burr et al., 2024). Despite these policies, many teachers report that smartphone use remains out of control, which continues to make it difficult to maintain focus and facilitate effective learning in the classroom. Removing smartphones from children’s daily lives can significantly improve their ability to concentrate, retain information, and engage in meaningful, face-to-face social interactions. By reducing the distractions caused by smartphones, students can enhance their academic performance and develop stronger interpersonal skills.



The Cognitive Impact of Smartphones

Given the findings of neuroscientific research, it is clear that smartphones pose a significant threat to children’s cognitive development. The mere presence of a smartphone, even when turned off, can reduce working memory and cognitive functioning (Ward, 2017). For children, who are in critical stages of brain development, this cognitive drain can hinder their ability to focus, think critically, and solve problems. These fundamental skills are essential for academic success, emotional regulation, and social interactions. Allowing children access to smartphones can disrupt this developmental process, making it harder for them to build the necessary foundation for self-regulation and independent thinking. Limiting smartphone use, or not providing them at all, can mitigate these cognitive impairments, fostering better mental clarity, improved learning, and stronger cognitive abilities that are crucial for their overall growth and future success.



The Link Between Social Media and Mental Health Decline

While some argue that social media fosters connection, the evidence suggests that it often worsens mental health conditions in young people. Research indicates that excessive social media use is strongly linked to increased rates of depression, anxiety, and suicidal ideation. Between 2011 and 2021, reports of persistent sadness among high school students rose from 28% to 42%, and suicidal ideation increased from 16% to 22% (CDC, 2023b). This troubling trend parallels the rise of social media use, suggesting that constant exposure to curated, idealized content online exacerbates feelings of inadequacy, loneliness, and stress. Given these findings, providing children with smartphones that grant access to social media platforms can significantly contribute to these mental health risks, making it all the more important to carefully consider the impact of early smartphone use on young minds.


Flip Phones: A Safer Alternative

Some parents argue that children need a phone for safety reasons. However, any legitimate need for a phone—such as contacting parents or emergency use—can be met with a basic flip phone that does not connect to the internet. A flip phone provides a means of communication without exposing children to the risks of social media, cyberbullying, and addictive online content. By opting for a simpler device, parents can ensure their children have access to emergency communication while also protecting them from the potential harms associated with smartphone use.



Conclusion

In conclusion, the evidence against providing smartphones to children is both compelling and concerning. Smartphones are powerful adult tools that are often ill-suited for developing minds. Research indicates that excessive screen time, especially when paired with unrestricted access to social media, has a direct link to attention problems, cognitive impairment, and a significant rise in mental health issues such as depression, anxiety, and suicidal ideation. With the brain's executive functioning and impulse control not fully developed until the mid-20s, young people are simply not equipped to handle the complex risks associated with smartphone use. Additionally, the presence of smartphones—whether in use or not—has been shown to hinder concentration and cognitive performance, making it harder for children to develop essential life skills like critical thinking and problem-solving.

Furthermore, the widespread use of smartphones in schools has raised concerns about their impact on learning, as teachers report that students are often distracted and disengaged. Despite policies designed to limit smartphone use in educational settings, the negative effects persist, underlining the need for more effective solutions. While some argue that smartphones can provide safety and communication for children, the reality is that a basic flip phone offers a much safer alternative—allowing children to stay connected while avoiding the dangers of social media, cyberbullying, and the addictive nature of constant online engagement.

Ultimately, the best choice for parents concerned about their children's well-being is to opt for alternatives that allow communication without the drawbacks of smartphones. By doing so, parents can foster healthier relationships, promote better mental health, and help their children build stronger focus, social skills, and critical thinking abilities. Protecting children from the risks associated with smartphones is an investment in their future, ensuring they grow up in a balanced and supportive environment, free from the overwhelming distractions and dangers of today's digital world.
