Pets aren't just recipients of our love — they have a remarkable positive effect on our health and lifespan. Dog owners tend to have healthier hearts and less loneliness. Learn the science behind this two-way relationship.
On my journey working in health and longevity, I discovered a warm truth: pets aren't just recipients of our love — they also have a remarkable positive effect on our health and lifespan. This article shares the science behind it.
Much research has found a link between owning a dog and better heart health. Dog owners tend to have lower blood pressure and stress levels, partly because walking their dog provides regular exercise. A meta-analysis pooling data from over 3.8 million people found that dog ownership was associated with a 24% lower risk of death from any cause and a 31% lower risk of cardiovascular death, with the effect strongest in people with a prior cardiac event (Kramer et al., Circulation: CQO, 2019).
What I find equally important is the effect on mental health. Pets help reduce loneliness, anxiety, and depression — and longevity research shows loneliness and social isolation are risk factors for mortality on par with physical factors (Holt-Lunstad et al., Perspect Psychol Sci, 2015). Interestingly, chronic stress also accelerates inflammation in the body, a driver of aging — I wrote about this on the human-health side in Inflammaging: chronic inflammation and the genes that speed aging on Geneus DNA. Having a living being waiting at home, loving us unconditionally, therefore has immeasurable healing power. This connects with the human-dog bond.
The most beautiful part is that this relationship is a two-way loop. When we take our dog out to exercise, they stay strong and so do we. When we care for their nutrition, we tend to care more about our own health too. A systematic review also confirms a protective association between pet ownership and cardiovascular health (Yeh et al., PLoS ONE, 2019). Living with a pet is a health investment that benefits both sides. This connects with genetics and pet lifespan.
As someone who prioritizes living long with quality, I see caring for a pet's health and caring for my own as one and the same thing. Because when our pet is with us strong and for a long time, we receive happiness and good health in return. This is why I believe in holistic health care for both people and animals.
Next time you take your dog for a walk, know that you're caring for both your health at once. Pets are a gift that gives both love and good health. Caring for them so they stay with us a long time is profoundly valuable. We'd like to care for your health and your pet's health from the DNA level, feel free to consult the Geneus Pet team and Geneus DNA team.
1. Does owning a dog really improve health?
Many studies find that owning a dog is linked to better heart health and lower stress, partly from getting more exercise. A meta-analysis also links dog ownership to lower mortality.
2. Can pets help mental health?
Yes, a lot. Pets help reduce loneliness, anxiety, and depression, and loneliness and social isolation are themselves risk factors for lifespan.
3. Why is it called a two-way relationship?
It's a two-way loop. We care for our pet, get exercise and pay more attention to health, so both sides benefit together.
