Why Does Music Give You Chills?

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.

Gray Areas

But there are competing theories. Neuroscientist Jaak Panksepp, for example, discovered that sad music triggers chills more often than happy music. He argues that a melancholy tune activates an ancient, chill-inducing mechanism—a distress response our ancestors felt when separated from family. When a ballad makes us feel nostalgic or wistful, that evolutionary design kicks into gear.

What’s interesting about Panksepp’s theory, though, is that chills don’t sadden most people. The experience is overwhelmingly positive. Recent research shows that sad music actually evokes positive emotions—sadness experienced through art is more pleasant than the sadness you experience from a bad day at the office.  

And this may hint at another theory. The amygdala, which processes your emotions, responds uniquely to music. A somber tune may activate a fear response in the amygdala, making your hair stand on end. When that happens, your brain quickly reviews whether there’s any real danger. When it realizes there’s nothing to worry about, that fear response becomes positive. The fear subsides but the chill remains.

Anything Goes

You can feel chills from any genre, whether it’s Mozart, Madonna, tango, or techno. It’s the structure—not the style—that counts. Goosebumps most often occur when something unexpected happens: A new instrument enters, the form shifts, the volume suddenly dims. It’s all about the element of surprise.

Well, maybe.

The most powerful chills may occur when you know what’s coming next. When our expectations are being met, the nucleus accumbens becomes more active. This ties back to that dopamine-inducing guessing game our brain likes to play. As a result, being familiar can enhance the thrill of the chill. (Perhaps that’s why 90 percent of musicians report feeling chills.)

Your personality matters, too. Scientists at UNC Greensboro found that people who are more open to new experiences are more likely to feel a quiver down their spine (possibly because open individuals are more likely to play instruments). Meanwhile, researchers in Germany found that people who felt chills were less likely to be thrill seekers, but were more reward-driven.

Big Questions
Who Was Chuck Taylor?

From Betty Crocker to Tommy Bahama, plenty of popular labels are "named" after fake people. But one product with a bona fide backstory to its moniker is Converse's Chuck Taylor All-Star sneakers. The durable gym shoes are beloved by everyone from jocks to hipsters. But who's the man behind the cursive signature on the trademark circular ankle patch?

As journalist Abraham Aamidor recounted in his 2006 book Chuck Taylor, All Star: The True Story of the Man behind the Most Famous Athletic Shoe in History, Chuck Taylor was a former pro basketball player-turned-Converse salesman whose personal brand and tireless salesmanship were instrumental to the shoes' success.

Charles Hollis Taylor was born on July 24, 1901, and raised in southern Indiana. Basketball—the brand-new sport invented by James Naismith in 1891—was beginning to take the Hoosier State by storm. Taylor joined his high school team, the Columbus High School Bull Dogs, and was named captain.

After graduation, instead of heading off to college, Taylor launched his semi-pro career playing basketball with the Columbus Commercials. He’d go on to play for a handful of other teams across the Midwest, including the the Akron Firestone Non-Skids in Ohio, before finally moving to Chicago in 1922 to work as a sales representative for the Converse Rubber Shoe Co. (The company's name was eventually shortened to Converse, Inc.)

Founded in Malden, Massachusetts, in 1908 as a rubber shoe manufacturer, Converse first began producing canvas shoes in 1915, since there wasn't a year-round market for galoshes. They introduced their All-Star canvas sports shoes two years later, in 1917. It’s unclear whether Chuck was initially recruited to also play ball for Converse (by 1926, the brand was sponsoring a traveling team) or if he was simply employed to work in sales. However, we do know that he quickly proved himself to be indispensable to the company.

Taylor listened carefully to customer feedback, and passed on suggestions for shoe improvements—including more padding under the ball of the foot, a different rubber compound in the sole to avoid scuffs, and a patch to protect the ankle—to his regional office. He also relied on his basketball skills to impress prospective clients, hosting free Chuck Taylor basketball clinics around the country to teach high school and college players his signature moves on the court.

In addition to his myriad other job duties, Taylor played for and managed the All-Stars, a traveling team sponsored by Converse to promote their new All Star shoes, and launched and helped publish the Converse Basketball Yearbook, which covered the game of basketball on an annual basis.

After leaving the All-Stars, Taylor continued to publicize his shoe—and own personal brand—by hobnobbing with customers at small-town sporting goods stores and making “special appearances” at local basketball games. There, he’d be included in the starting lineup of a local team during a pivotal game.

Taylor’s star grew so bright that in 1932, Converse added his signature to the ankle patch of the All Star shoes. From that point on, they were known as Chuck Taylor All-Stars. Still, Taylor—who reportedly took shameless advantage of his expense account and earned a good salary—is believed to have never received royalties for the use of his name.

In 1969, Taylor was inducted into the Basketball Hall of Fame. The same year, he died from a heart attack on June 23, at the age of 67. Around this time, athletic shoes manufactured by companies like Adidas and Nike began replacing Converse on the court, and soon both Taylor and his namesake kicks were beloved by a different sort of customer.

Still, even though Taylor's star has faded over the decades, fans of his shoe continue to carry on his legacy: Today, Converse sells more than 270,000 pairs of Chuck Taylors a day, 365 days a year, to retro-loving customers who can't get enough of the athlete's looping cursive signature.

What Is the Difference Between Generic and Name Brand Ibuprofen?

What is the difference between generic ibuprofen vs. name brands?

Yali Friedman:

I just published a paper that answers this question: Are Generic Drugs Less Safe than their Branded Equivalents?

Here’s the tl;dr version:

Generic drugs are versions of drugs made by companies other than the company which originally developed the drug.

To gain FDA approval, a generic drug must:

  • Contain the same active ingredients as the innovator drug (inactive ingredients may vary)
  • Be identical in strength, dosage form, and route of administration
  • Have the same use indications
  • Be bioequivalent
  • Meet the same batch requirements for identity, strength, purity, and quality
  • Be manufactured under the same strict standards of FDA's good manufacturing practice regulations required for innovator products
