About this episode
It’s not too late to reset the screen-time limits and boundaries you've set for your kids—and the reasons to take action are becoming increasingly clear. In this episode, Dr. Carrie Mackensen joins host Nicki Petrossi to unpack the science behind interactive screens and short-form media and how they impact children's brain development. Her clear, accessible approach helps parents understand what's happening neurologically and how to make informed choices. Our brains operate using two key systems: the emotional center, which rewards us with dopamine when something feels good, and the thinking brain, where we analyze, reflect, and make decisions. Activities like riding a bike or climbing a tree provide healthy dopamine boosts through effort and engagement. But scrolling social media or watching endless YouTube Shorts floods kids’ brains with 100 to 200 times the dopamine—without any effort—bypassing the thinking brain entirely. Over time, this leads to an underdeveloped thinking brain and an overstimulated emotional center. The result? Kids who are increasingly anxious, withdrawn, emotionally dysregulated, and lack critical thinking skills. The good news: It’s not too late to make a change. Thanks to the brain’s neuroplasticity, you can help rewire these patterns and restore balance at home. Dr. Mackensen, a clinical psychologist, parent coach, and mom of two boys, shares her proven approach in conversation with Nicki from Scrolling 2 Death. Together, they offer practical tools and clear screen-time guidelines to help families create healthier digital boundaries. This is an episode every parent needs to hear.
