Chewing gum may help get that song out of your head. Catchy tunes can end up playing over and over again in your head, but a group of researchers has found that chewing gum might prevent these earworms from getting stuck. The team recruited 98 people and had them listen to catchy music. “After playing the participants two different catchy tunes the researchers asked them to try not to think of the songs they had just heard over the next three minutes. Each time the participant thought of the song, they were instructed to hit a key.” A third just listened to the songs, a third listened while tapping their fingers, and the rest listened while chewing gum. “Those who chewed gum reported hearing the song less than those with no activity or who just tapped their fingers.” Those who chewed the gum were 33% less likely to have the song come back into their head. The researchers think the act of chewing gum may make the music harder to hear, which prevents it from catching in your brain as easily.
