Stay Cool and Live Longer? University of Michigan Study

Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why. Researchers at the University of Michigan Life Sciences Institute have identified a genetic program that promotes longevity of roundworms in cold environments—and this genetic program also exists in warm-blooded animals, including humans. "This raises the intriguing possibility that exposure to cold air—or pharmacological stimulation of the cold-sensitive genetic program—may promote longevity in mammals," said Shawn Xu, LSI faculty member and the Bernard W. Agranoff Collegiate Professor in the Life Sciences at the U-M Medical School.
