Owning a dog could extend your life span
Dog owners live longer than people without a canine pet, two new studies suggest.
And older people who live alone are a third less likely to die after a heart attack if they have a furry friend at home, according to the Swedish researchers.
Loneliness plays a well known role to the detriment of older people in the US, not only hindering them from living happy lives, but often actually increasing their risks of death and chronic illnesses.
The American Heart Association ( AHA), which released an accompanying statement, noted that it's not exactly proof that dogs will keep you healthier, but it's pretty good evidence that having one is beneficial for older people.
"While these non- randomized studies cannot ' prove' that adopting or owning a dog directly leads to reduced mortality, these robust findings are certainly at least suggestive of this," said chair of the AHA's writing group, Dr Glenn Levine.
In fact, he and the AHA put out a statement in 2013 summarizing all the various ways and research that has suggested that owning pets is good for your heart.
For the latest pair of studies to drive home that point, the researchers used national patient registry to track people who suffered heart attacks and strokes. In the first, study, they looked at data on virtually everyone between the ages of 40 and 85 who had been hospitalized after a heart attack or stroke between 2001 and 2012.
Of those, almost 155,000 had had a stroke - and five percent of those owned a dog.
Nearly 182,000 had had a stroke. Heart attack patients who lived alone, were hospitalized for a heart attack, then came home to a dog were 33 percent less at-risk of dying after returning.
That reduction was actually more significant than even co- habituating with people. Those who lived with a partner or children were only 15 percent less likely to die after a heart attack.
Similarly, stroke survivors were more likely to keep surviving, if they had a dog.
After a stroke, people were 27 percent less at- risk of dying if they owned a dog, but only 12 percent less at- risk if their partner or children lived with them.
In a second study, University of Toronto researchers looked at data on over 3.8 million people, documented in 10 prior studies. Their findings suggested even more robust benefits of dog ownership.
Man's best friend was linked to a 24 percent lower risk of death by any cause, a 65 percent lower risk of dying after a heart attack and 31 percent less probability of dying of any cardiovascular cause.
That's not surprising when you consider that previous studies, too, have documented the lower cholesterol and blood pressure profiles of dog owners and the share amount of time they spend being physically active on the animal's behalf.
Dogs are supposed to get between 30 minutes and two hours of exercise a day.
So it stands to reason that those with pets would have a more athletic physique.
"We know that social isolation is a strong risk factor for worse health outcomes and premature death," said Dr Tove Fall, an Uppdsala University professor and study co-author.
"Previous studies have indicated that dog owners experience less social isolation and have more interaction with other people."
