More than any other animal, dogs have evolved to become acutely attuned to humans and our behavior and emotions. While dogs are able to understand many of the words we use, they’re even better at interpreting our tone of voice, body language, and gestures. And like any good human friend, a loyal dog will look into your eyes to gauge your emotional state and try to understand what you’re thinking and feeling (and to work out when the next walk or treat might be coming, of course).
While most dog owners are clear about the immediate joys that come with sharing their lives with canine companions, many remain unaware of the physical and mental health benefits that can also accompany the pleasure of playing with or snuggling up to a furry friend. It’s only recently that studies have begun to scientifically explore the benefits of the human-animal bond. The American Heart Association has linked the ownership of pets, especially dogs, with a reduced risk for heart disease and greater longevity.
Studies have also found that:
- Dog owners are less likely to suffer from depression than those without pets.
- People with dogs have lower blood pressure in stressful situations than those without pets. One study even found that when people with borderline hypertension adopted dogs from a shelter, their blood pressure declined significantly within five months.
- Playing with a dog or cat can elevate levels of serotonin and dopamine, which calm and relax.
- Pet owners have lower triglyceride and cholesterol levels (indicators of heart disease) than those without pets.
- Heart attack patients with dogs survive longer than those without.
- Pet owners over age 65 make 30 percent fewer visits to their doctors than those without pets.
One of the reasons for these therapeutic effects is that dogs (and cats) fulfill the basic human need to touch. Even hardened criminals in prison have shown long-term changes in their behavior after interacting with dogs, many of them experiencing mutual affection for the first time. Stroking, hugging, or otherwise touching a loving animal can rapidly calm and soothe us when we’re stressed or anxious. The companionship of a pet can also ease loneliness, and most dogs are a great stimulus for healthy exercise, which can substantially boost your mood and ease depression.
