Pets are a common cultural phenomenon all over the world. Dogs have always been known as the ideal American pet, and in England, no stereotypical rainy afternoon can be spent without a cup of tea and a tabby cat curled up in a person’s lap. Even smaller animals such as hamsters, rabbits, and fish have become customary additions to any home. But why has the tradition of keeping animals in our homes prospered for such a long amount of time?

According to multiple studies, people with pets are both physically and mentally healthier.  For example, in a study by the National Center for Health Research, Dr. Dana Cassciotti and Dr. Diana Zuckerman tested patients by giving them difficult mathematical tests in limited amounts of time. Some patients were given canine companions to sit with them during the exam, and these people had lower heart rates and blood pressure. In addition to getting more questions right, these patients also reported feeling more calm than their counterparts who didn’t have dogs. This is because adding access to a nonjudgemental living companion provides humans with a comforting support system.

The Center of Disease Control and Prevention also found that the bond between humans and pets enforces a healthy lifestyle that can help combat depression and any stress or anxiety related disorder. This is because being around animals can increase a person’s dopamine and serotonin, which are hormones in the body that control happiness and relaxation. This allows pet owners to feel a sense of contentment that those who live without pets may not.

Not only are pets a fun incorporation into the daily lives of humans, but these animals can also do wonders in improving one’s mindset and physical well-being.
