Screens and stress: Helping your family reset and recharge

Avatar

While screens seem essential to modern family life, research suggests these devices take a toll on children’s mental and physical health.

Child psychiatrist Dr. Victoria Dunckley has studied screen time’s effects on young people for years. Her findings reveal that excessive screen exposure, whether for school, social media, or gaming, can disrupt children’s emotional stability, focus, and behavior. In some cases, screen time can even lead to a condition Dr. Dunckley calls Electronic Screen Syndrome (ESS), where the nervous system becomes overstimulated, mimicking the symptoms of chronic stress.

The author of “Reset Your Child’s Brain” proposes a radical yet effective solution: a four-week “electronic fast” that reduces or completely removes interactive screen use to reset children’s nervous systems and restore balance to their lives.

Dr. Dunckley’s research shows that each time a child interacts with a screen, their brain responds as though it were facing a potential threat, activating the fight-or-flight response. This neurological reaction was designed for real-world dangers and involves increased heart rate, blood pressure, and stress hormones such as cortisol.

However, screen interactions do not allow for the physical discharge of this energy. So instead of engaging muscles to flee or fight, children remain stationary, trapping stress in their bodies and escalating their brain’s sense of threat. Over time, the brain begins to adapt to this heightened state, causing chronic stress symptoms that can lead to disruptive behaviors, anxiety, and even depression.

The effects go beyond the immediate fight-or-flight response. Screen time impacts the brain’s frontal lobe, the area responsible for planning, impulse control, and emotional regulation. Brain scans of children with heavy screen exposure show reduced blood flow to this region, potentially impairing critical learning and social skills. Even children who play nonviolent, educational games display similar changes in brain activity, indicating that overstimulation, rather than content, is a primary concern.

Misdiagnoses

The symptoms of ESS, such as impulsivity, irritability, trouble focusing, and anxiety, can mimic conditions like attention-deficit/hyperactivity disorder (ADHD), anxiety disorders, and mood disorders. Dr. Dunckley warns that these misdiagnoses can lead to unnecessary medications. Often, reducing screen time alone can lead to dramatic improvements in children’s behaviors and emotional regulation, alleviating symptoms that previously seemed unmanageable.

Parents of neurotypical children are also seeing the impact of excessive screen use. Increased aggression, difficulty with friendships, and struggles in school have all been linked to excessive screen exposure. With a four-week screen fast, these issues often diminish, helping children regain emotional control, perform better academically, and reconnect socially.

Dr. Dunckley’s recommended four-week “electronic fast” involves removing all interactive screen time and allowing limited passive screen time—no more than five hours weekly of calm, non-animated programming. This restriction allows the nervous system to return to a stable baseline, lowering stress hormones and helping reset the body’s natural rhythms. During this period, the brain also begins to recover, with blood flow returning to the frontal lobe, supporting improved focus, creativity, and impulse control.

Families who commit to the electronic fast often report noticeable improvements within weeks: Children sleep better, focus more in school, and become more engaged with family activities. Some parents even decide to extend the fast beyond four weeks, having observed its profound effects on their child’s mood, behavior, and academic performance.

Strategies

The fast requires commitment and structure. Here are some strategies Dr. Dunckley suggests to make it a success:

1. Get the family on board: For the reset to work effectively, the entire family should reduce screen time. This sets a strong example and helps parents recognize how screen habits impact their interactions and focus. Family members supporting each other creates an atmosphere of accountability and shared commitment.

2. Plan alternative activities: To prevent boredom and fill the gap left by screens, plan a mix of physical, creative, and social activities. Kids might enjoy sports, board games, creative projects, and puzzles, while teenagers may appreciate activities like chess, basketball, or hiking. Many parents find that their children’s initial resistance fades as they rediscover old hobbies and develop new interests.

3. Track changes: Dr. Dunckley suggests setting measurable goals, such as fewer tantrums or improved focus and organization. Tracking these changes can provide motivation and help parents make data-driven decisions about whether to reintroduce screens gradually after the fast.

4. Avoid overexplaining: While kids may ask why they need to fast from screens, Dr. Dunckley advises against extensive explanations. Children often look for loopholes and may try to wear down their parents’ resolve. Instead, frame it as an experiment and reassure them that the goal is to see if it helps.

5. Introduce screens slowly post-fast: If families decide to reintroduce screen time, Dr. Dunckley recommends cautiously starting with short periods, 15 minutes one day a week, for example, and observing any behavior changes. The goal is to find each child’s unique tolerance level before negative symptoms reemerge.

Overstimulation

Not every child exhibits screen-related symptoms, but many do. Dr. Dunckley suggests looking for specific behaviors that may indicate overstimulation. If your child seems constantly “revved up,” has trouble sleeping, struggles with school performance, or has issues with social interactions, a screen fast could be beneficial. Other red flags include frequent tantrums, mood swings, and difficulty focusing.

Parents who try the fast often notice significant improvements in their children’s behavior and family’s overall interactions and emotional closeness. Some families find the experience so rewarding they continue the lifestyle long-term, structuring screen time limits to maintain the benefits.

As Dr. Dunckley’s research highlights, reducing screen time is more than just limiting exposure; it’s about resetting children’s brains and nervous systems to support healthier development. A four-week screen fast gives children the time to recalibrate, allowing them to recover from the overstimulation that screens introduce into their lives.

This journey proves transformative for many families, reshaping daily routines and creating a more connected, engaged household. If you’re wondering if screen time might affect your child’s mood, behavior, or learning, consider a screen fast; it may just be the lifestyle shift your family needs.
