NU.edu – The Negative Effects of Technology on Children

In today’s digital world, technology is an integral part of daily life. Devices such as smartphones, tablets, gaming consoles, and computers are deeply embedded in our personal and professional environments. While these advancements have undoubtedly improved education, communication, and entertainment, they also present significant concerns—especially when it comes to their effects on children. National University (NU.edu), a leader in education and child development studies, emphasizes the importance of understanding the negative consequences that can arise from excessive technology use among youth.

This article delves into the numerous risks associated with the overuse of digital devices by children, including physical health consequences like obesity, psychological and behavioral issues, and deficits in social skill development.

1. Obesity and Physical Health Risks

Sedentary Lifestyle

One of the most direct consequences of excessive technology use is a sedentary lifestyle. Children who spend hours watching television, scrolling on tablets, or playing video games are less likely to engage in physical activity. The World Health Organization recommends at least 60 minutes of moderate to vigorous physical activity daily for children aged 5–17. However, many children fail to meet this guideline due to screen time.

Poor Eating Habits

The screen-entertainment environment also contributes to unhealthy eating behaviors. Children are more likely to consume high-calorie snacks while watching television or using digital devices. In many cases, eating becomes mindless and habitual, leading to excessive calorie intake and poor nutritional choices.

Disruption of Sleep Patterns

Electronic devices emit blue light, which interferes with the body’s production of melatonin—a hormone that regulates sleep. Many children and adolescents who use screens before bedtime report difficulty falling asleep, poor sleep quality, and shorter sleep durations. Sleep deprivation is a known contributor to weight gain and other health issues in children.

2. Behavioral and Emotional Issues

Attention Deficits

Studies show that excessive screen time, particularly from fast-paced media like video games and social media, can shorten attention spans and hinder cognitive development. Children are increasingly showing signs of difficulty concentrating, especially in school environments where sustained focus is critical.

Increased Aggression

Certain types of digital content—especially violent video games or aggressive social media interactions—can lead to increased aggression and impulsivity in children. Prolonged exposure to violent content desensitizes children to violence, potentially encouraging aggressive behaviors.

Anxiety and Depression

Social media, in particular, has been linked to rising rates of anxiety, depression, and low self-esteem in children and teens. The constant pressure to compare oneself to others, fear of missing out (FOMO), and exposure to cyberbullying can be detrimental to mental health.

3. Impaired Social Skills

Reduced Face-to-Face Interaction

Digital communication—texting, chatting, and video calling—often replaces face-to-face interactions. This substitution can hinder the development of essential social cues, such as reading body language, maintaining eye contact, and listening attentively.

Decline in Empathy

Children who are heavily reliant on technology may struggle with developing empathy. Studies suggest that the more time children spend on screens, the less emotionally responsive they become. Lack of real-world socialization reduces their ability to understand and share the feelings of others.

Decreased Communication Skills

Frequent digital communication can limit opportunities to practice verbal and non-verbal communication skills. Over time, this can result in difficulty expressing emotions, forming relationships, and resolving conflicts in a healthy manner.

4. Academic Impact

Distractions and Poor Performance

Many students use technology during class or study sessions, leading to divided attention. Constant notifications and the lure of entertainment can drastically reduce academic performance. According to research, multitasking with digital devices results in poorer memory retention and lower test scores.

Cheating and Plagiarism

Technology also makes it easier for students to access unauthorized information, contributing to a rise in cheating and plagiarism. Without appropriate digital literacy education and supervision, students may misuse technology rather than using it as a learning tool.

5. Parental Challenges

Difficulty Monitoring Content

Parents often struggle to monitor the type of content their children are exposed to. Inappropriate media can influence a child’s worldview, desensitize them to adult themes, or expose them to dangerous online communities.

Dependency and Resistance

Many children develop an emotional attachment or dependency on digital devices. When access is restricted, they may exhibit withdrawal-like symptoms including irritability, tantrums, or aggression. This can create a power struggle between parents and children.

6. Developmental Delays in Younger Children

Language Development Issues

For toddlers and preschoolers, excessive screen time can significantly delay language acquisition and development. Children learn language best through human interaction—not from screens. The American Academy of Pediatrics advises that children under 2 years old should have very limited screen exposure.

Motor Skill Deficiencies

Young children also need to engage in physical play to develop fine and gross motor skills. Sitting passively in front of a screen doesn’t provide the necessary stimuli to enhance hand-eye coordination, balance, or manual dexterity.

Strategies for Mitigating the Effects

To minimize the negative effects of technology, parents, educators, and caregivers must implement proactive strategies:

• Establish screen time limits appropriate to a child’s age.
• Encourage outdoor play and physical activity.
• Model balanced technology use as adults.
• Use parental control tools and content filters.
• Promote face-to-face family interactions, like shared meals and tech-free zones.
• Educate children on responsible digital behavior.
• Integrate technology with real-world learning, such as using apps that promote creativity and problem-solving.

NU.edu – The Negative Effects of Technology on Children

In today’s fast-paced digital age, children are growing up surrounded by technology, from smartphones and tablets to gaming consoles and laptops, all of which play a major role in shaping their everyday experiences. While these devices offer significant educational and entertainment benefits, there is increasing concern from educational institutions like National University (NU.edu) about the growing negative consequences of excessive technology use in children. Among the most pressing risks are rising rates of childhood obesity, behavioral problems, and deficits in essential social skills. Obesity, now more prevalent among children than ever before, is heavily linked to a sedentary lifestyle fueled by screen-bound entertainment that replaces physical activity. Children are spending hours glued to their screens, consuming digital content while remaining physically inactive, which not only limits their opportunities for exercise but also promotes unhealthy eating habits, such as snacking on junk food during screen time. These habits contribute directly to weight gain, decreased physical fitness, and in some cases, early onset of lifestyle-related diseases such as diabetes or high blood pressure. Compounding the problem is the interference of screens with sleep routines—especially in the evening—due to the blue light emitted by devices, which suppresses melatonin production and disrupts the natural sleep-wake cycle. Sleep deprivation in children not only affects physical health but also impairs cognitive function, mood stability, and academic performance. Moreover, psychological and behavioral issues are becoming increasingly common among children who are excessively exposed to digital technology. Research has shown a correlation between high screen time and attention deficits, with children finding it increasingly difficult to concentrate, complete tasks, or sustain attention in school. Fast-paced, highly stimulating digital content—particularly in the form of video games and social media—can make traditional classroom activities feel dull, reducing a child’s ability to engage in learning and develop patience and perseverance. In addition, content consumed through technology often includes violent or inappropriate material, which may desensitize children to aggression, encourage impulsive behavior, and increase irritability. Social media, another prevalent technological force, plays a significant role in shaping self-esteem and emotional health, often negatively. Children and adolescents frequently compare themselves to idealized images and lives portrayed online, leading to feelings of inadequacy, anxiety, and depression. The constant pursuit of likes, comments, and validation online fosters a shallow sense of self-worth, making emotional stability increasingly dependent on digital affirmation. Furthermore, the rise of cyberbullying has introduced a new form of psychological threat, one that often occurs out of adults' sight and can severely damage a child’s mental well-being. Social skill deficits are another deeply concerning outcome of excessive technology use. Face-to-face communication is essential for developing empathy, understanding non-verbal cues, and building meaningful relationships—all of which are compromised when digital interactions replace in-person experiences. Children who spend more time texting or gaming than engaging in real-world play may struggle with interpersonal communication, exhibit poor listening skills, and show reduced ability to interpret facial expressions or body language. These limitations can make school, social interactions, and eventually workplace environments challenging, as children grow into adults who lack confidence in social settings. At home, families also face growing challenges related to device use. Many parents report difficulty controlling their children’s screen time or monitoring what content is being consumed. When technology limits are imposed, children may exhibit signs of dependency, such as withdrawal symptoms, tantrums, or aggression—behaviors comparable to those observed in individuals with substance addiction. The struggle to balance discipline and freedom around screen use can strain parent-child relationships, diminish the quality of family bonding time, and lead to unhealthy household dynamics. In younger children, the effects of overuse are particularly pronounced. Toddlers and preschool-aged children, who are in critical stages of brain and language development, need rich verbal interactions and physical exploration of their environments to thrive. Passive screen use at this age can significantly delay language acquisition, hinder cognitive growth, and even limit fine and gross motor skill development, especially when time spent on screens replaces essential activities like playing with toys, interacting with caregivers, or moving around freely. In addition to these developmental setbacks, there is growing concern that children are becoming overly reliant on technology for problem-solving and creativity, as opposed to developing independent thinking and imagination. Educational systems also bear the burden of digital overuse, with teachers frequently reporting that students are distracted by their phones during lessons or struggle to engage deeply with educational material. Digital multitasking, such as switching between academic content and entertainment apps, leads to fragmented attention, lower retention of information, and diminished academic outcomes. The ease of copying material from online sources also contributes to rising incidents of plagiarism, undermining the development of academic integrity and critical thinking. Despite these risks, it is important to recognize that not all technology use is inherently harmful. When used intentionally and in moderation, technology can serve as a valuable tool for learning, creativity, and communication. Educational games, digital storytelling, and virtual collaboration platforms can support cognitive development and global awareness. The key lies in how technology is integrated into children's lives. Parents, educators, and caregivers must adopt proactive strategies to mitigate the risks, such as setting firm screen time limits, encouraging physical play, promoting open communication, and modeling healthy digital behavior themselves. Designating screen-free zones in the home, such as during meals or before bedtime, can help children disconnect and reengage with the real world. Additionally, promoting media literacy and teaching children how to use technology responsibly are essential for empowering them to navigate digital spaces safely. National University emphasizes that the conversation about children and technology must shift from simply permitting or banning devices to guiding their mindful use and ensuring that real-world developmental needs are not neglected. Children need environments that nurture their physical, emotional, and social growth—environments that challenge them to interact, move, explore, and empathize. Technology, when used correctly, can enhance these environments, but when overused or misused, it becomes a barrier to healthy development. The solution is not to reject technology outright but to restore balance by prioritizing human connection, physical activity, emotional well-being, and lifelong learning.

In the rapidly evolving digital era, technology has become an omnipresent force in children’s lives, bringing with it a blend of opportunities and challenges; while devices such as smartphones, tablets, and computers can provide educational resources, entertainment, and social connectivity, the overuse of technology among children raises serious concerns about their physical, psychological, and social development, as highlighted by National University (NU.edu), which underscores the negative effects of excessive screen time on children, particularly noting how this phenomenon contributes to increased rates of childhood obesity, behavioral problems, and deficits in social skills that are critical for healthy growth. First and foremost, the sedentary nature of screen-based activities directly promotes obesity by encouraging children to engage less in physical activity and more in prolonged periods of inactivity, often seated and immobile, which dramatically reduces calorie expenditure; this shift away from active play and sports is compounded by the tendency for children to snack mindlessly while using screens, frequently opting for high-calorie, low-nutrition foods and sugary beverages, which further exacerbates the risk of weight gain and associated metabolic health problems, such as type 2 diabetes and cardiovascular disease, conditions that were once rare in young populations but are now emerging as significant pediatric concerns. Additionally, technology use, particularly before bedtime, disrupts children’s natural circadian rhythms due to blue light exposure from screens, which suppresses melatonin production and delays sleep onset; this lack of sufficient and quality sleep not only contributes to weight gain by altering hormones that regulate hunger and satiety, like leptin and ghrelin, but also impairs cognitive function and mood, fostering irritability and difficulty concentrating in academic and social settings. Beyond the physical health implications, excessive device use is strongly linked to a range of behavioral and emotional issues that can hinder a child’s ability to thrive; for example, the constant stimulation from fast-paced digital content, such as video games and social media, may shorten attention spans and impair executive functions, making it harder for children to sustain focus, manage impulses, and complete tasks in traditional learning environments, which can lead to poor academic performance and frustration. Moreover, exposure to violent or inappropriate media content can desensitize children to aggression and increase the likelihood of impulsive or aggressive behaviors, especially when combined with reduced parental supervision. Emotional well-being is also at risk, as social media platforms can foster anxiety, depression, and low self-esteem among young users, who are frequently exposed to idealized portrayals of peers and influencers, creating unrealistic expectations and feelings of inadequacy; the phenomenon of “fear of missing out” (FOMO) and the prevalence of cyberbullying contribute to this mental health crisis, sometimes resulting in withdrawal, loneliness, or even suicidal ideation among vulnerable children and adolescents. The negative impact of technology extends deeply into social skill development, as children who spend excessive time interacting with screens often miss out on valuable real-world social experiences that teach empathy, cooperation, and effective communication; face-to-face interactions allow children to interpret subtle nonverbal cues such as facial expressions and tone of voice, skills that are difficult to acquire through texting or social media alone. As a result, many children demonstrate impaired social understanding and reduced ability to form and maintain meaningful relationships, which can negatively affect their emotional resilience and sense of belonging. This decline in social competence can also lead to increased social anxiety and isolation, as children become more comfortable in virtual worlds than in physical social settings. Parental and familial challenges are integral to this discussion, as many caregivers find it increasingly difficult to monitor and regulate their children’s screen time in an environment saturated with digital devices; attempts to restrict device use can provoke resistance, tantrums, or withdrawal symptoms in children who have developed psychological dependencies on technology, creating conflicts that strain family relationships and hinder effective parenting. Furthermore, the educational system faces hurdles as technology can become a double-edged sword in classrooms: while it offers innovative tools for learning, it also introduces distractions, encourages multitasking that reduces comprehension, and facilitates cheating and plagiarism due to easy access to online information, ultimately compromising the quality of education. For very young children, the effects of screen overexposure are even more alarming, as these formative years are critical for language acquisition, motor skill development, and social bonding; passive screen use in toddlers and preschoolers can delay speech development, reduce opportunities for physical exploration, and limit interactive experiences with caregivers, all of which are essential for healthy brain development. The American Academy of Pediatrics strongly advises minimal screen exposure for children under two years old, emphasizing that direct human interaction remains the most effective way to foster early learning and emotional growth. In light of these multifaceted challenges, it is essential for parents, educators, and policymakers to develop comprehensive strategies to mitigate the negative effects of technology on children; such strategies include setting age-appropriate screen time limits, encouraging regular physical activity and outdoor play, fostering face-to-face social interactions, and modeling balanced technology use by adults themselves. Additionally, implementing parental controls and content filters, creating tech-free zones in the home, and promoting media literacy can empower children to navigate the digital landscape safely and responsibly. National University emphasizes that the goal is not to vilify technology, but to restore balance and ensure that children’s developmental needs—physical, emotional, and social—are prioritized alongside their digital experiences. When managed thoughtfully, technology can serve as a powerful tool for enhancing learning, creativity, and connectivity without compromising health or social well-being. Ultimately, fostering an environment where children have ample opportunities for physical movement, real-world engagement, emotional expression, and intellectual curiosity will safeguard their holistic development and prepare them to thrive in an increasingly digital future.

Conclusion

While technology will remain a central part of modern life, it is essential to understand its limitations and potential harms, especially for growing children. The key is moderation and mindful usage. Schools, parents, and society must collaborate to cultivate digital environments that enrich rather than diminish children's development. Fostering real-world connections, physical activity, and emotional intelligence will help counteract the negative effects and prepare children for a healthier future.
