Anyone who has troubles falling asleep knows how frustrating it can be —sometimes it seems like no matter how tired you are, getting some REM take a LOT of effort. Counting until a thousand, lying perfectly still, drinking warm milk —methods that just don’t really do the trick sometimes. But maybe, maybe the secret to catching some much-needed Zs at night as been with us all along. Listen up, restless sleepers.

Scientists have determined that leaving one or both feet out from under the covers will help put you to sleep a lot faster than if you’re all tucked in.

They’re not exactly sure why it works, but they think it has something to do with heat. Since they don’t have hair, feet conduct heat really well. In your feet there are blood vessels that carry heat away from your body, so leaving one or both of your feet out will ultimately make you a ton more comfortable, and making going to sleep much easier. “It helps lower your internal temperature, which signals to your body that it’s time to drift off to sleep,” NY Mag reports.
