You know how parents will often sing their babies to sleep? It turns out music can also help adults fall asleep at night, too. One song in particular, “Weightless” by Marconi Union, is scientifically proven to aid the sleep process. The song is designed to sound like a heartbeat, and the listener’s heartbeat actually slows to match the song, bring blood pressure down and inducing sleep. But the song is so effective, researchers caution against listening while driving.
