Walk into almost any home or classroom and you’ll see it: kids with tablets, phones, and video games at their fingertips. Screen time is a part of childhood now—but how does it affect growing brains? Science is giving us some clear answers, especially when we look at two key brain chemicals: dopamine and serotonin.
This is a short intro gives a quick overview of our downloadable ebook that provides research based information on what devices are doing to our kids' brains.
The Brain’s Reward System: Dopamine
Dopamine is often called the “feel‑good” chemical because it fires when we experience something rewarding. For kids, that could be solving a tough math problem, finishing a puzzle, or scoring a goal in soccer. Those natural dopamine hits motivate them to try again, stick with challenges, and build long‑term motivation.
But screens deliver fast, repeated dopamine hits—every new level, notification, or quick video clip gives a burst of reward without much effort. Over time, this can dull a child’s motivation for slower, real‑life challenges. A child used to instant digital rewards might find reading a chapter book or practicing an instrument “boring” because it doesn’t give the same quick feedback.
Mood, Sleep, and Regulation: Serotonin
Serotonin is the brain chemical that helps kids feel calm, balanced, and socially connected. It also regulates sleep patterns and impulse control.
Behavior, Academics, and Social Life
When dopamine systems are over‑stimulated and serotonin systems are under‑supported, kids often struggle in ways parents and teachers notice:
Behavior: More impulsivity, frustration, and difficulty calming down.
Academics: Shorter attention spans, less persistence with challenging work, and weaker long‑term learning habits.
Social Life: Less practice reading faces and emotions, fewer opportunities to develop empathy and teamwork skills.
Super affordable ebook that provides research-based information on what happens to our kids' brains on devices...and how screen time is impacting a whole generation.
