Some 5.741 people participated in the study that revealed a beneficial effect of pet ownership on several of the classical factors for coronary heart disease. Dog owners in the McHargetal survey also reported better physical and mental health than non dog-owners. They go to the doctor less often. Fewer take medication for high blood pressure, sleeping difficulties, high cholesterol or a heart problem. They also report greater satisfaction with their physical fitness.
Pets can act as emotional substitutes for spouses, romantic partners and children.
They found that the people who felt closer to their pets tended to be those without a present spouse or romantic partner, have no children or have no children in the present home. They found that widows, single people, and empty nesters are more likely to emphasize the companionship qualities of pets. Pet ownership has many benefits. Animal companions affect both the emotional and physical well being of their owners. They provide people with unconditional love, and research has shown that they can decrease depression and stress, and lower blood pressure.
