Summary

Screen time can physically change brain structure and pathways.
Dopamine release from screens creates a craving cycle.
Heavy screen use impacts attention, problem-solving, and social skills.

Research indicates that regular screen time can lead to physical changes in a child's brain, affecting memory and planning areas. These alterations can reroute brain network connectivity, potentially causing unforeseen consequences.

This extensive digital exposure is linked to cognitive challenges, including shorter attention spans and difficulties with multitasking. The brain's reward system, stimulated by dopamine release from screens, can foster a craving for more usage, diminishing the appeal of real-world interactions and social engagement.

Experts emphasize the importance of balance, suggesting digital detox periods and prioritizing face-to-face interactions. The type of screen content also plays a role, with mindful use being less detrimental than passive scrolling.
