A Health Benefit of Roller Coasters | The Atlantic

For years in practice, Wartinger noticed anecdotal reports from patients who had passed small kidney stones during and immediately after visiting the Disney theme parks. It was a correlation he might not have noticed in another place, he told me: “This mass migration helped bring it to my attention.”

But one particular gentleman really inspired Wartinger. The man rode Big Thunder Mountain Railroad at Disney’s Magic Kingdom, and then passed a small stone. Then he did it again and passed another. And then another. “That was just too powerful to ignore,” Wartinger said. “I’d been hearing these anecdotal stories for a couple years, and then I thought, okay, there’s really something here.”

The stones passed 63.89 percent of the time while the kidneys were in the back of the car. When they were in the front, the passage rate was only 16.67 percent. That’s based on only 60 rides on a single coaster, and Wartinger guards his excitement in the journal article: “Preliminary study findings support the anecdotal evidence that a ride on a moderate-intensity roller coaster could benefit some patients with small kidney stones.”
