Are pets a healthy pleasure? The influence of pets on blood pressure

Pet owners often describe their pets as important and cherished family members who offer solace in times of stress. This article considers evidence suggesting that pets influence human blood pressure. Studies on this topic extend current research testing the hypothesis that having other people around in stressful times can buffer the negative consequences of stress. The existing data suggest that people perceive pets as important, supportive parts of their lives and that the presence of a pet is associated with significant cardiovascular benefits, among both people with normal blood pressure and those with high blood pressure. Studies about pets and blood pressure have examined both naturally occurring and randomly assigned pet ownership, but are limited by their focus on responses to short-term, acute stress. Future prospective studies should explore the influence of pets on people at risk for cardiovascular disease and also consider explanatory mechanisms for the pet effect.
