Did you know that owning a pet could be good for your heart?

American Heart Association studies concluded that dog ownership is associated with a lower risk of death over the long term, which is possibly driven by a reduction in cardiovascular mortality.

Just petting an animal has a calming effect that can suppress stress hormones, said John P. Erwin III, MD, a cardiologist and Chair of the Department of Medicine.

If you don’t own a pet, consider volunteering at a shelter or spending time with a friend’s dog.
