Social media could be draining children of their ability to concentrate, a new study says.

Children who spend a lot of time on Instagram, Snapchat, TikTok, Facebook, Twitter or Messenger gradually become less able to focus and pay attention, researchers reported Monday in the journal Pediatrics Open Science.

This might partially explain why ADHD diagnoses have increased among kids in recent years, researchers said.

"Our study suggests that it is specifically social media that affects children's ability to concentrate," said senior researcher Torkel Klingberg, a professor of cognitive neuroscience at Karolinska Institutet in Sweden.
