00:00This new study is raising serious concerns for every parent.
00:03Teen brains may be changing because of social media.
00:07Researchers in the U.S. tracked thousands of kids for years.
00:11And what they found is hard to ignore.
00:13Teens using social media more than five hours a day show measurable changes in their brains.
00:19Not small changes.
00:21Real visible differences on MRI scans.
00:24The amygdala is affected.
00:25The part that controls emotions.
00:27The prefrontal cortex, too.
00:30Responsible for decisions and self-control.
00:32These areas are still developing during teenage years.
00:36Which means the impact could be long-lasting.
00:39And possibly harder to reverse.
00:41This comes as thousands of lawsuits claim platforms were designed to be addictive for young users.
00:47Experts say the most critical brain development window is between ages 10 and 25.
00:52Exactly when usage is the highest.
00:54So this isn't just about screen time anymore.
00:57It may be about brain development itself.
00:59self.
