The Neurological Impact of Screen Time in Children and Adolescents

If you grew up before the year 2000, you had the privilege of a childhood before technology, where boredom was normal, imaginations were used, and days were spent playing outside with neighbors. Now, when you go to restaurants, grocery stores, or other public places, most people are looking down at their devices instead of engaging with others.

Eye contact and a friendly smile from a passerby are now a thing of the past. We have become so distracted that the important things in life, like relationships and human connections, are no longer a priority.

Have you ever questioned how this new normal could be impacting your child’s brain development? This article highlights the profound impact of excessive screen time on a child’s cognitive, behavioral, academic, linguistic, and social-emotional development. In addition, this article explores strategies that all caregivers can implement to manage and reduce the negative impact of screen time on their children.

A child is the most precious gift the Lord will ever give us, so it is important to honor God through our parenting, even when it’s hard. After all, with everything we consume our minds in this life, the only thing you can bring with you to heaven is your children.

The Impact of Screentime on Academic and Language Development in Children

Decreased executive functioning, reduced academic performance, and delays in language development are all correlated with excessive screen time (Mupalla et al., 2023). A study from Scientific Reports in 2022 analyzed the brain structure of children ages 3-5, according to each child’s digital media use. The results found significant differences in brain structure based on the amount of screen time these children were exposed (Hutton, 2022).

Up to 90% of a child’s brain development happens before age five. As children grow, their language develops through frequent, consistent, and quality interactions with caregivers. When a child spends too much time on their devices, the auditory cortex of the brain (responsible for developing social skills and language) becomes overstimulated.

Talking, playing, and exploring are all critically necessary for early brain development (Bredehoft Ph.D., 2025). It is essential that a child’s early learning be developed from interactive, face-to-face experiences rather than passive viewing.

Neuronal pruning explains the amazing learning potential during the childhood years of development. The “use it or lose it” principle is important because we want children to develop as many brain connections as possible. The pathways in the brain that are used most will remain strong, while those that are used the least will be shut down.

The Impact of Screentime on a Child’s Social and Emotional Development

Studies of young children indicate that screen usage is an independent risk factor for reduced psychological well-being. Research suggests that digital media impacts the development of the brain areas responsible for empathy, attention, memory, and early reading skills in children ages 3-5 (Hutton, 2022).

It is also important to note that early exposure to violence increases a child’s likelihood of engaging in antisocial behavior, with the most obvious effects appearing during early adolescence and beyond (Hill; Flannery). We will discuss adolescents later in this article.

With so much information available to us, we can easily conclude that children younger than age three would be best served by avoiding the use of digital media. This allows a child to grow and develop normally, giving them the best chance at living out God’s greater purpose for their life.

The Physical and Behavioral Impact of Screentime on Children

Research indicates that high levels of screen time are associated with a variety of social, emotional, and behavioral problems in both children and adolescents. In addition to developmental delays, children who use screens for more than two hours per day are likely to exhibit both physical and behavioral problems, such as difficulty with impulse control, cognitive flexibility (i.e., creative problem-solving), and an inability to regulate emotions (Bredehoft, Ph.D., 2025).

Increased TV exposure from 6-18 months of age was associated with emotional reactivity, aggression, and externalizing behavior (i.e., impulsivity, defiance, hyperactivity).

The largest long-term study of child health and brain development in the United States is the Adolescent Brain Cognitive Development (ABCD) Study, tracking more than 11,000 children for ten years, starting from age 9-10. This study aimed to uncover how biology, environment, and experience can interact over time and influence brain development (Rock, 2025). The study observed a correlation between screen time and poor physical health.

For example, adequate sleep is critical for neurodevelopment, brain growth, formation of memories, brain recovery, and energy (Rock, 2025). The blue light emitted by screens suppresses melatonin production, making it harder for a child to fall and stay asleep. Adequate sleep is one of the most important things in a child’s physical development, indicating that poor sleep will have an impact on the child’s overall health.

In addition, excessive screen time often results in a lack of physical activity and a poor diet, contributing to health problems. As a result, a child can experience weight problems, body image issues, and low self-esteem. The Lord gave us one body, and we must care for it.

As technology use increases with each passing year, children are less engaged with their environment and nature, impacting mental health and overall well-being (Mupalla et al., 2023). Spending time outside, with nature, exploring, and playing is essential for brain development and mental health.

If your child is struggling in social settings, engaging minimally with caregivers, and struggling to regulate their behavior, it might be due to excessive screen exposure (Rock, 2025). However, even if your child is not currently exhibiting any of these symptoms, it will likely present itself as the child ages, and the damage is more difficult to reverse.

The Impact of Screen Time on Spirituality

As one can conclude, if a child is spending their free time in front of a screen, they are not using that time to draw closer to God. The greatest gift we can give our children is to foster a deep, authentic relationship with their Savior. Distractions in this generation are a significant barrier to both child and adult spiritual health.

Stillness, rest, and quiet are essential for a growing relationship with God, and a brain that is overstimulated will miss the most precious part of life, Jesus. Imagine how the world would change if we replaced scrolling social media with scrolling scripture.

The Impact of Screen Time on Adolescents

A growing body of evidence determined that adolescent brains can be structurally changed by what’s called “toxic screentime.” This includes, but is not limited to, playing video games, computer/app games, watching videos online, social media, pornography, and scrolling (Hutton, 2022).

Research continues to support limiting screen time to less than two hours a day for older children. Exceeding that amount has been associated with increased risks of anxiety, depression, and other emotional challenges (Asher, 2025).

There is an abundance of studies highlighting the impact toxic screen time has on our teens, including but not limited to:

• An analysis of thirty-two studies involving over 25,000 students found that social media use was significantly associated with several mental health concerns, including anxiety, suicidality, depression, loneliness, low self-esteem, and fear of missing out (Bredehoft, Ph.D., 2025).
• A National Institute of Health study found children exposed to excessive amounts of toxic screen time experienced thinning of the brain’s cortex, the area of the brain related to critical thinking and reasoning (Bredehoft, Ph.D., 2025).
• Another study determined that higher levels of media multitasking (such as watching TV while browsing online) contribute to lower scores on standardized tests measuring academic performance in both English and Math. Media multitasking was also found to have a negative impact on executive functioning in teenagers, notably on memory, inhibition, and the capacity to switch between tasks (Mupalla et al., 2023).
• Screen time-induced poor sleep, nighttime use of digital devices, and dependency on mobile phones have been associated with depressive symptoms in adolescents and a higher risk of ADHD (Hill & Flannery).
• A 2024 Centers for Disease Control and Prevention study found that 50% of children aged 12-17 reported being on a screen for over four hours per day, equivalent to a part-time job. Those children had significantly higher rates of depression and suicidal ideation compared with those exposed to less screen time (Hill & Flannery).

Video Games

As previously stated, the ABCD study observed that adolescents who play excessive amounts of video games demonstrate reduced activity in the region of the brain tied to reward processing, called the caudate nucleus (Rock, 2025).

Teens who fall into this category are more likely to experience screen addiction and often seek out more stimulation through gaming and social media. Therefore, it is important to eliminate all use of toxic screens as they are designed to be more addictive and more harmful to a child’s development.

Social Media

Suicide is the second leading cause of death in teens aged 10–24 years old. Social media and internet use were found to be directly associated with an increase in suicide attempts (Sedwick et al., 2019). Social media is difficult for parents to monitor, and the risks are inherently dangerous.

It is the primary platform used by child predators to groom and lure children who do not have the cognitive ability to discern the warning signs. During adolescence, the brain is focused on social development and seeking acceptance from peers. Teens often use social media comments and likes to measure self-worth.

Before social media, that feedback loop was limited to in-person interactions with a small group of peers. Now, through apps and social media platforms, teens are exposed to a constant stream of approval/disapproval (Asher, 2025).

This amplification places stress on the adolescent brain and increases the risk of social anxiety, low self-esteem, and depression. Due to the social and emotional sensitivity of adolescence and the difficulty for parents to monitor activity, children and teens should not be exposed to social media.

Is your child addicted to digital media?

It might surprise you to learn that the brain reacts to digital media in the same way that it reacts to illicit drugs, triggering a strong dopamine response in the brain that is unattainable from real-world experiences. As a result, children are highly susceptible to screen cravings and addiction. Children demonstrating addictive behavior to their devices often exhibit structural changes in the brain that impact cognitive and emotional regulation (Hill & Flannery).

Several indicators can assist a caregiver in determining if a child is addicted to digital media. For example, when a child uses screen time as an escape, when screens are preferred over time with friends and family, and when asking the child to turn off the screen triggers a negative emotional response. Another example of addiction is if the child is being dishonest, sneaking additional screen time beyond what is allowed by the caregiver.

If you suspect your child is struggling with screen addiction, rules and boundaries regarding screen time must be firm and strictly enforced. Like weaning an addict off their drug of choice, you will also have to wean an addicted child off screens. For example, if the child currently spends four hours a day on digital media, start by reducing this by one hour each day.

This will lessen the symptoms of withdrawal that your child will experience upon removal of the heavy dopamine response. When you remove technology from a screen addicted child, they may panic and exhibit highly unstable and irrational outbursts.

Once the screens are removed, the period of withdrawal will last approximately seventy-two hours as the brain adjusts to these changes, varying depending on the severity of the addiction. Caregivers should have other activities available to replace screen time to help the child adjust, such as quality time with parents and outings.

The period of withdrawal can be difficult, but it will pass. Parents mustn’t give in when the child begs or lashes out. It is often the most difficult teaching moments that have the greatest impact on a child’s development.

What is the solution?

All parents want their children to have the best chance at a healthy and fulfilling life. We can reduce the negative impact of excessive screen time and promote a child’s development and well-being by increasing knowledge and encouraging alternative activities that stimulate development. By reading this article, you have already taken the first step to better understand how technology could be impacting your child.

The two most important things to keep in mind are the amount of time spent on digital media and the content being consumed during that time. Enjoying a two-hour family movie together is different than spending two hours scrolling content on social media. It is essential that a child is not allowed unsupervised screen time to ensure they are not being exposed to violent content, bullying, substance use, sexual content, and child predators.

Professional Recommendations

Thankfully, we can look to the American Academy of Child and Adolescent Psychiatry (AACAP) for adequate recommendations regarding safe screen exposure. The AACAP recommends zero screen time for children aged 0-2. During this stage, children should spend all their time exploring their environment and interacting with caregivers to ensure healthy brain development.

For children ages 2-5, no more than 1 hour of screen exposure per day is recommended, and that hour should be limited to educational programming or shared screen time (i.e., watching a movie as a family). Personal screen time at this age should be limited to special occasions only.

The AACAP recommends no more than two hours per day of screen exposure for children ages six and older, including the adolescent years. It is important in this stage for caregivers to focus on encouraging healthy habits and limiting activities that include screens (i.e., removing screens during family mealtimes and outings).

In addition, removing screens approximately 1 hour before bedtime is essential to ensure adequate sleep. All devices should be removed from the child’s bedroom when they are sleeping.

Modeling Healthy Digital Hygiene

Parents have become reliant on screens as babysitters, bargaining tools, distractions, or ways to stop tantrums. The importance of parents avoiding this trap cannot be overstated, as this cycle can significantly disrupt development. Parents must become familiar with and use parental controls, practice boundaries with their children, and model good screen behavior.

The amount of time parents spend on their devices directly correlates with how much time a child also spends on devices (Mupalla et al., 2023). The old saying “do as I say, not as I do” is not an acceptable response when teaching your children rules and boundaries around screen time. Parents must model the behavior they expect from their children.

If parents require themselves to follow the same rules as their children in this regard, parents can increase quality time with their children, strengthening family bonds, and living out God’s true design of the family.

The family unit is the most influential relationship in your child’s life, and the nature of those relationships will influence the child’s future relationships. It will determine how they bond with a future spouse, how they parent their own children, what type of employee or student they are, and so on.

God’s design for the family was not created by accident. It is a sacred bond and a beautiful gift from the Lord that should be nurtured and prioritized so that children develop the ability to engage in healthy relationships for the rest of their lives.

Wait until 8^th

Wait until 8^th is a movement encouraging parents to delay giving their children smartphones until at least the end of eighth grade. The longer you wait, the greater the likelihood that your child will build a solid foundation of social and emotional development (Asher, 2025).

Most parents have heard their child complain that everyone else has a phone or that all their friends are allowed to play video games, leaving the child feeling frustrated and left out. As a result, parents often give in to guilt and pressure to give their child a device before it is developmentally appropriate. This is a great opportunity for parents to teach their children that the fact that someone else has something does not mean that others are entitled to it.

How will I contact my child?

Parents and caregivers in this generation are convinced that they must be able to contact their children at all times. Parents, who themselves grew up without cell phones, often use this excuse to justify giving their child a phone before developmentally appropriate. If there is a special circumstance requiring a parent to contact their child and a landline is not available, there are several options to choose from.

A great alternative to a cell phone is a Gabb phone. Gabb phones are internet-free, app-free, game-free phones that allow the child to call/text pre-approved contacts only. There are a variety of watches on the market that allow a parent to track and contact their child without the toxic elements of the internet and apps. No matter the situation, there are many alternatives that enable parents to contact and protect their children at the same time.

Toxic Screentime

As you may have noticed, different types of screens have greater risks than others. For instance, watching a family movie together is an acceptable form of screen consumption as it promotes family interaction and discussion rather than passive consumption (Hill; Flannery). Educational screen time is also acceptable if used after age 2 and for no more than 1 hour per day.

On the other hand, significantly harmful screen time includes fast-paced content with shifting visuals and apps/games that offer prizes and push constant interaction to keep kids engaged. Moderation of this type of digital media use is not recommended, as no amount of toxic screen time is safe for a developing brain.

Conclusion

If you are concerned that it is already too late to make a change and the damage is already done, let me provide some reassurance. Some disruptions to healthy development can be corrected over time. The brain has an incredible ability to heal, rewire itself, and adapt. However, with each passing year of your child’s life, the brain lessens its ability to heal.

When a child’s brain development is not hindered by external factors, the child will develop the ability to regulate social, emotional, behavioral, and physical health. It takes approximately 25 years for the brain to fully develop and mature, and it is the responsibility of the parent to enforce boundaries and provide structure during this stage, even when it is hard.

In 2026, we are raising children in a completely different culture than any generation prior. There will be many learning experiences, and often tough decisions must be made to protect the children of the future from the world and from themselves.

More than ever before, parents must use the discernment of the Lord to determine healthy boundaries for their children. Romans 13:13 says “do not be conformed to this world,” and Colossians 3:2 says, “set your mind on things that are above, not on earthly things.” These are only two of the many verses in the Bible that command our attention to heavenly, rather than worldly, matters.

Digital media is a worldly idol designed to consume the attention of our hearts and minds, pulling us away from a relationship with our Creator. Jesus himself speaks to the value of children in all four Gospels, and parents are ordered to protect and nurture them, even if doing so requires difficult decisions. Anything that draws our children or us away from the Lord must be removed, because the only thing you can bring with you to heaven is your children.
