If you have trouble sleeping, there’s a chance it’s not the sugar or caffeine you might’ve had. It could be that you keep tapping that refresh button on Facebook, Twitter, Instagram, Vine, or whatever the hell Peach is. A recent study by University of Pittsburgh researchers revealed that young adults on social media for good portions of the day sleep less than those who aren’t.

The 1,700+ respondents (U.S. residents aged 19 to 32) keep a median of 61 minutes on social media each day, checking their channels about 30 times a week. Nearly 60% of them acknowledged problematic sleeping patterns. The reason’s not totally locked, as researchers can’t nail down if it’s because people use social media to cope with insomnia or because their social appetite keeps them up at night.

In truth, it’s probably both. But what do I know? I’m not a doctor. I’m just some young adult checking social media when I can’t sleep and can’t sleep because I check social media.
