(CNN) — Need an excellent reason to add a dog to your life? How about living longer?
“Our analysis found having a dog is actually protective against dying of any cause,” said Mount Sinai endocrinologist Dr. Caroline Kramer, lead author of a new systematic review of nearly 70 years of global research published Tuesday in “Circulation,” a journal of the American Heart Association.
The review of the health benefits of man’s best friend analyzed research involving nearly 4 million people in the United States, Canada, Scandinavia, New Zealand, Australia and the United Kingdom.
“Dog ownership was associated with a 24% reduction in all cause mortality,” said Kramer, an assistant professor in the division of endocrinology and metabolism at the University of Toronto.
The meta-analysis found an even bigger benefit for people who had already had a heart attack or stroke.
“For those people, having a dog was even more beneficial. They had a 31% reduced risk of dying from cardiovascular disease,” Kramer said.
