How Excessive Screen Time Impacts a Child’s Developing Brain

A recent study analyzed dozens of fMRI studies and found that excessive smartphone or internet use in teens and young adults is linked to real changes in the brain—especially in the prefrontal cortex, which governs impulse control, attention, and decision-making.

What does that mean for your child?

The brain regions that help them focus and say “no” to distractions can become less active—similar to what we see in recognized behavioral addictions.

➡️ This isn’t to scare you—it’s to inform you. The developing brain is adaptable, and even small lifestyle shifts can steer it back on track.

What parents can do right now:

✅ Limit non-educational screen time—especially before bed

✅ Encourage offline hobbies like drawing, sports, and reading

✅ Model balance—children learn by watching us too

A brain in balance is a brain that learns well, manages emotions, and makes healthy choices. Small changes today can build strong neural habits for tomorrow’s success.
