As a cardiologist, Dr Dhruv Kazi once wrote about the health benefits of dogs. It wasn’t until 2021, after moving to Boston and enduring a lonely pandemic year in ICU work, that he adopted Rumi-a high-energy Vizsla puppy.
Rumi transformed Dr Kazi’s routine: increased walks, neighborhood connections, and emotional stability. He credits the dog with preserving his mental well-being.
Decades of research show dog owners tend to have lower blood pressure, reduced heart disease risk, and a 24% lower mortality rate over 10 years. The American Heart Association recognizes this link, though it does not recommend getting a dog solely for heart health.
Experts suggest physical activity is key-dog walkers often meet weekly exercise guidelines. But if owners are inactive, their dogs likely are too.
Tove Fall, a Swedish epidemiologist, found that dog owners with Type 2 diabetes are more likely to share the condition, highlighting shared lifestyle risks.
Mental health gains are also significant-especially for those living alone. Dog companionship counters loneliness, a known health threat.
Yet pets demand commitment: training, vet costs, and grief upon loss. Still, Dr Kazi calls them a 'joy.'
