Pets help keep people healthy and active both physically and mentally. Research has reported finding pet owners to be less stressed than non-pet owners. People with less stress tend to also be more physically healthy. For example, pet owners tend to have lower blood pressure and be at a lower risk for heart disease.

One study done at the New York State University at Buffalo studied 48 male and female stock brokers who suffered from high blood pressure and no other medical disorders. The participants all lived alone with no pet for at least five years. Half of the participants were given a pet to take home and the other half were not. After six months, researchers found that the group of stockbrokers that now had pets also had significantly lower blood pressure than the stockbrokers that did not.
