why does music give us chills
Answers
When your playlist strikes all the right chords, your body can go on a physiological joyride. Your heart rate increases. Your pupils dilate. Your body temperature rises. Blood redirects to your legs. Your cerebellum—mission control for body movement—becomes more active. Your brain flushes with dopamine and a tingly chill whisks down your back.
About 50 percent of people get chills when listening to music. Research shows that’s because music stimulates an ancient reward pathway in the brain, encouraging dopamine to flood the striatum—a part of the forebrain activated by addiction, reward, and motivation. Music, it seems, may affect our brains the same way that sex, gambling, and potato chips do.
Strangely, those dopamine levels can peak several seconds before the song’s special moment. That’s because your brain is a good listener—it’s constantly predicting what’s going to happen next. (Evolutionarily speaking, it’s a handy habit to have. Making good predictions is essential for survival.)
But music is tricky. It can be unpredictable, teasing our brains and keeping those dopamine triggers guessing. And that’s where the chills may come in. Because when you finally hear that long awaited chord, the striatum sighs with dopamine-soaked satisfaction and—BAM—you get the chills. The greater the build-up, the greater the chill.
