The Benefits of Puppy Love
Pet ownership confers a sense of belonging and acceptance. Many studies have hypothesized that owning and caring for a pet has qualitative psychological and physical benefits, but recent studies are quantifying these advantages. Pet owners have long reported better overall well-being compared to peers without pets, including greater self-esteem, greater conscientiousness, less stress, less negativity, and less fear. They routinely report more exercise and physical activity, which itself is positively correlated to improved psychological and physical health. Additionally, pets often complement, rather than compete, with other forms of social support.
An recent study reports that pet ownership may have quantifiable cardiovascular benefits. Evidence suggests that pet ownership, specifically dog ownership, leads to lower blood pressure and lower cholesterol. Dog owners also have improved survival following a heart attack. The authors hypothesize that the link is due to the improved emotional state of pet owners, which leads to decreased autonomic activity and improved endothelial function, which, in turn, causes improved coagulation, immune function, and electrolyte balance, and related cardiovascular parameters. Collectively, these benefits lead to less cardiovascular dysfunction and disease.
In a related study, not owning a pet was a significant predictor of mortality in heart attack survivors. The link between not owning a pet and depression was significant, indicating that pet ownership improves survival by preventing depression, anxiety, and a lack of social support that contributes to post-heart attack deaths.
Luckily, this research does not apply only to adult pet owners. New research shows positive health benefits for adolescents who have a pet in their lives. Specifically, adolescents are more likely to engage in physical activity if their family has a dog. Improved physical activity for children and adolescents has innumerable psychological and physical benefits.
October is World Animal Month. Celebrate by thanking your pet for all he does for you. The long walks, the wet noses, the tennis-ball chasing, the purrs, and the fur on all your clothes and furniture are all making you happier and healthier.
