In a recent episode of “The Dan Buettner Podcast,” longevity expert Dan Buettner, founder of the Blue Zones organization in Minneapolis, Minnesota, highlighted a straightforward habit that could add years to a person’s life: owning a dog.

Scientific evidence supports the claim

Buettner cited a study published by the American Heart Association in the journal Circulation that found dog owners experience a 24% lower risk of all‑cause mortality compared with non‑owners. The benefit is even more pronounced for people who have already suffered a major cardiac event—such as a heart attack or stroke—where having a canine companion reduced the risk of death by up to 33%.

Why dogs may boost longevity

Epidemiologists and psychologists point to three primary mechanisms. First, dog owners walk an average of 22 more minutes per day than non‑owners, according to research published in BMC Public Health. This extra activity helps more people meet weekly physical‑activity guidelines, which are linked to better cardiovascular health.

Second, interacting with a pet lowers cortisol, the body’s primary stress hormone, while increasing oxytocin, dopamine and serotonin—neurochemicals associated with reduced stress and improved mood.

Third, dogs act as natural “social catalysts,” encouraging owners to engage with neighbors and community members. The U.S. Surgeon General has labeled chronic loneliness a public‑health epidemic, comparing its health impact to smoking 15 cigarettes a day. By providing companionship, dogs help combat isolation, especially for single‑person households.

Connections to the Blue Zones lifestyle

Buettner explained that the health benefits of dog ownership align with the principles observed in the world’s “Blue Zones”—regions with the highest concentration of centenarians. Those areas share common habits: regular low‑intensity movement, a strong sense of purpose, stress reduction and deep social connections. A dog can help a person incorporate all four without the need for a complex health regimen.

Practical steps for prospective owners

For those considering adding a canine companion, Buettner recommends adopting from a shelter or rescue organization. He emphasizes that the relationship works both ways: while owners gain health benefits, dogs receive a loving home and a purpose.

“If you want to live longer, go adopt a dog,” Buettner concluded.
