National Pet Day highlights how pets support routines and wellbeing, according to science

Research cited by the CDC and NIH links close relationships with pets to daily routines, lower stress markers such as cortisol and blood pressure, and increased social interaction for some people.

National Pet Day on April 11 draws attention to the everyday relationships people form with animals they live with. Research cited by the CDC and NIH connects those relationships to routines, stress responses, social contact, and some physical health measures. Scientists treat the human-animal bond as a subject of study rather than just a cultural idea. Researchers also note that results vary and the evidence is still developing. Key points: - The CDC reports that pets can increase opportunities for exercise, outdoor time, and social interaction. - The NIH and other studies have found that interacting with animals can be associated with lower cortisol and lower blood pressure in some settings. - Longitudinal work has linked dog ownership and dog walking with higher physical activity and maintained physical function among older adults. - Reviews find many studies connect pet ownership with reduced social isolation, while findings on loneliness are mixed. - The American Heart Association noted a possible association between pet ownership, especially dogs, and lower cardiovascular risk, but also cautioned the evidence is not strong enough to recommend getting a pet solely to prevent heart disease. Summary: These findings help explain why National Pet Day resonates: the human-animal bond often touches daily routines, social contact, and measurable stress-related markers. Undetermined at this time.
