According to research highlighted by the National Institutes of Health in the US (NIH) and supported by a growing body of behavioural science, our relationships with pets can shape both our physical health and emotional wellbeing in meaningful ways.
For many people, the benefits begin with stress reduction. According to research from the NIH, spending time with animals can lower cortisol levels. The calming, bonding hormone, oxytocin, also increases when we spend time with pets. Even just patting a dog or sitting with a cat can help the body shift into a more relaxed state. This simple, daily regulation can have lasting effects on overall health.
Pets also encourage movement. Dog owners, in particular, tend to be more active than non-pet owners. Regular walks support cardiovascular health and improve mental clarity. Research suggests that people who walk their dogs are significantly more likely to meet recommended physical activity guidelines. Walking with a dog may also feel more calming than walking alone, helping to reduce stress while creating a healthy routine.
Loneliness is another area where pets make a measurable difference. Companion animals provide a consistent presence and a sense of connection. This is especially important for older adults or people living alone. Studies have found that pet owners report lower levels of loneliness, as caring for their pet increases their feelings of wellbeing.
Beyond the home, pets can strengthen social connections. Dogs often act as social bridges, prompting conversations between strangers and helping people build relationships within their communities. Research shows that pet owners are more likely to form friendships and receive social support through these interactions.
For children, growing up with animals can support emotional and social development. Studies link pet ownership with improved self-esteem, empathy, and social skills. Caring for an animal also teaches responsibility and compassion through everyday actions such as feeding, grooming, and play.
Pets can also provide a strong sense of purpose. Feeding, walking, and caring for an animal creates routine and accountability. This structure can be especially valuable during stressful periods, when motivation is low or daily life feels uncertain. Pets rely on consistency, and that reliance often helps people maintain their own wellbeing.
Research shows that pets can help reduce symptoms of anxiety and depression. Many people describe feeling calmer and more supported in the presence of their animals. Therapy animals are now often brought into hospitals and care settings to reduce stress and provide comfort to patients.
Pets also play a quiet but important role in times of grief. Their presence offers stability without expectation. Studies have found that animals can provide a unique form of support during loss, simply by being there without judgment or the need for words.
There is also growing evidence that pets help anchor us in the present. Animals live in the moment, and interacting with them can encourage mindfulness. Research shows that people who engage mindfully with their pets, report improved psychological wellbeing. These small, shared moments help shift attention away from stress and into the present.
While the benefits are significant, pet ownership is not the same for everyone. The NIH notes that different animals offer different advantages. A dog may suit someone seeking more activity, while watching fish may provide calm for another person. Pets also require time, money, and emotional commitment, which can add pressure if not carefully considered.
What remains consistent across studies is the depth of the human-animal bond. Whether through companionship, routine, or simple presence, pets have a unique ability to support our health in ways that are both subtle and profound.
