We've all been there, trolling the Internet for cute animal videos, unable to get enough of the adorable scenes flashing before our eyes. But now there's an explanation for why we are drawn to such things. It's science, as explained by CNN.
Scientists have discovered that people are instinctively drawn to anything that has the features of a baby. That means large eyes, chubby cheeks, big foreheads and rounded features. Many scientists believe that this attraction is a matter of staying alive.
"Our survival depends on us taking care of our young. It's part of our human species to respond to these features," said Oriana Aragon, a Yale psychologist.
When we see those same features on animals—big eyes, chubby cheeks, etc.—we react in a similar fashion. Studies have found that the pleasure centers of our brains light up when we see something cute because there's a rush of dopamine to the brain.
"It is kind of a vice. We want our cute fix. There are entire things devoted to cuteness," Aragon said.
So next time you're searching the Internet for cute animal videos, just remember: You're not wasting time. It's actually good for your health!
