According to a study by the Minnesota Stroke Institute that followed more than 4,000 cat owners over 10 years, owning a cat can dramatically reduce a person's chance of dying from heart disease [source: Mundell]. Specifically, people who owned cats were 30 percent less likely to suffer a heart attack. Although those researchers cannot make the same conclusions about dogs based on the data they gathered, they suspect a dog study would provide similar results.
That study merely adds to the existing evidence that shows how animals can benefit human health. For example, psychologists have found reason to believe that owning a dog helps lower your blood pressure and your cholesterol [source: BVA]. And other research shows that pets help us feel better overall and help us to deal with stress, which can be a source of illness [sources: Laino, BBC News].
And let's not forget the benefits for the elderly. For example, one study observed neural activity in seniors while they walked or interacted with a dog [source: Motooka]. It turned out that walking with a dog gave seniors a boost in parasympathetic nervous system activity, which is good because the parasympathetic nervous system helps calm and rest the body.
For whatever reason, pets certainly can have a special effect on their owners. On the next page, find out more about pets' amazing ability to improve our health. Is it really possible for a dog to foresee its owner's seizures and even detect cancer?
Stories abound about the healing abilities of pets. For instance, one boy who did not talk for six years finally chose to start talking after a therapy dog visited his school [CBS News]. Organizations, such as the Delta Society, train dogs to help disabled people perform tasks. The Delta Society feels so strongly about the health benefits of animals to humans that it is dedicated to spreading knowledge about the issue as well as services.
The psychological benefits of pets can make a big difference in someone's life. This seems to be especially true for kids who are struggling to deal with death or illness in the family. Certain studies have concluded that children with dogs cope better with these serious situations [source: Howie]. Researchers believe this probably has to do with the obvious fact that pets provide love and with the fact that the structured routine required for taking care of a pet is a positive for the child. Kids aren't the only ones who benefit from pets during these difficult times; the spouses of cancer patients said they believed pets helped them cope as well.
