In 2019, the journal Circulation published a figure that was hard to ignore: dog owners showed a 24% lower risk of premature death. The science of pets deserved a closer look.
A Measurable Effect on the Heart
The American Heart Association published an analysis of multiple studies as early as 2013: owning a dog is associated with lower blood pressure, better triglyceride levels and faster cardiac recovery after stress. Researchers also found that heart attack survivors who own a dog show significantly higher one-year survival rates than those who don't.
Part of the explanation lies in physical contact. Stroking an animal lowers cortisol (the stress hormone) and increases oxytocin — the same hormone released during a hug.
What Daily Life Actually Changes
A dog owner walks an average of 2,200 steps more per day than someone without a pet. Over a year, that adds up to the equivalent of several extra marathons, without even thinking about it. The walks the animal requires become a physical activity routine that motivation alone might never have put in place.
The Impact on Mental Health
Loneliness is now recognised as a mortality risk factor comparable to smoking. Pets provide constant presence, a responsibility that structures the day, and a bond that doesn't judge. For elderly people living alone, having a pet is correlated with significantly reduced depression and longer-maintained independence.
Cats are no exception. A University of Minnesota study found that cat ownership was linked to a 30% lower risk of stroke.
A Note on Causality
Researchers are cautious. Part of the effect may be explained by reverse bias: people in good health are more likely to adopt a pet and care for it over the long term. A pet is not a medical prescription.
What is certain: a relationship with an animal, built over time with attentive care, produces real and measurable effects. The quality of that relationship matters as much as its mere existence.
What It Changes Day to Day
Fewer doctor visits, better sleep, more stable blood pressure, faster recovery from life's difficulties. These benefits accumulate over years. They don't replace a healthy lifestyle, but they add meaningfully to it.
Well-nourishing your pet, getting them checked regularly, giving them exercise and company: it's also taking care of yourself. That's exactly the conviction that has guided Pet Cheri's work from the beginning.
