Dog Ownership Linked to Longer Life, Longevity Expert Says

Owning a dog may be the most effective strategy for prolonging life, according to longevity expert Dan Buettner. Research indicates that dog owners experience a reduced risk of early death, especially from cardiovascular disease, and report lower rates of loneliness.

Buettner, founder of the organization Blue Zones, stated in a recent podcast episode that scientific evidence strongly supports the benefits of dog ownership for longevity. He cited studies showing that dog owners live longer, have fewer heart attacks, and suffer less from isolation.

According to research published in the American Heart Association journal Circulation, dog ownership is associated with a 24% reduction in all-cause mortality for the general population. For individuals who have already experienced a major cardiac event, such as a heart attack or stroke, living with a dog has been shown to reduce the risk of death by up to 33%.

Experts point to several reasons for these health benefits:

Increased Physical Activity

Studies published in BMC Public Health suggest that dog owners walk an average of 22 minutes more per day than non-owners. This increased activity helps them more consistently meet recommended weekly physical activity guidelines.

Stress Reduction

Interacting with a dog has been shown to lower cortisol, the body's primary stress hormone, while increasing levels of oxytocin, dopamine, and serotonin. A 12-year Swedish study of 3.4 million participants found that dog owners had lower blood pressure and decreased rates of cardiovascular disease.

Reduced Isolation

The U.S. Surgeon General has identified chronic loneliness as a national public health epidemic, with risks comparable to smoking 15 cigarettes a day. Dogs can act as social catalysts, encouraging community interaction and providing emotional attachment that combats isolation, particularly for individuals living alone.

Buettner noted that these benefits align with the principles observed in "blue zones," regions known for their high concentrations of centenarians. These principles include natural daily movement, a sense of purpose, stress reduction, and strong social connections. By incorporating dog ownership into daily life, individuals can naturally adopt habits that contribute to a longer, healthier life.
